ESS TS1 Dyno on my 330ci

[e34m5]

I just did mine last night..very dissappointing results.

Max RWHP = 250

We tried everything we knew but that was it. Considering the info from ESS says 284 RWHP that is a significant difference.

I expected some lower numbers on my car due to age, wear, temp, etc., but not that much. That's a 14% difference.

[Lemonsqr]

Wow, that is kind of dissapointing! details on age of car, mileage and temp please.

[EIAlfonso]

Do you have a graph that you could post up? Did you get a baseline reading?

[GodSendsDeath]

This don't sound right. Post some base line numbers and after TS. There must be something seriously wrong with you car because a lot of people have the kit and aren't showing such problems. Maybe some sort of boost leak or something.

[e34m5]

Car is 2001 with a little over 100k miles. I do not have a baseline before TS since I never thought I would need it. The boost is up to 8psi on the inlet side of the manifold, so that's probably around 7psi at the block.

The temp was about 89F last night so I would expect some loss, but not 35HP, maybe 5 or so.

We checked all the air passages very closely (even opened the air box at ESS's suggestion). Checked all pressure side as well.

We also added Octane Boost to the fuel just in case. Disconnected the battery to let the ECU re adapt as well.

So far all ESS suggests is that maybe the CATs are blocked, but here again all not that level.

I have the graph and will post later. Frankly at this point I am not sure it was worth the investment.

I felt from the day I installed it that it was low on power. 280 RWHP should make a 330 go like a scalded cat. My car, albeit stronger than before TS, never felt quite that strong.

Bottom line right now is that it seems it just doesn't make more than 250RWHP.

I am curious what others may show.

[GodSendsDeath]

Others show ESS posted numbers, few had install issues but once they took care of it the cars work just fine. I honestly think its your car doubt its the kit. You really need to check the cats also your fuel filter is it maybe clogged with junk from the gas thank. My friend here has a TS ESS kit and it rocks my sock i tell ya. Work it out don't give up.

[e34m5]

Remeber that this is a TS1...

I doubt fuel filter is an issue as t he A/F was perfect. The CAT's maybe. I am in search of some now.

[Lemonsqr]

If it is TS1 and you are up to 7-8psi, then it sounds like the blower is not the issue because the TS1 is rated at 6.5psi, right? What is the condition of the transmission? I know it is frustrating, but stay with it. We'll try to help as much as we can.

[GodSendsDeath]

Drive train loss due to high millage could be a issue too. Hope you don't think I am bashing you just throwing out ideas as to what might be wrong. Keep us posted.

VT1, TX2, now the TS1.... I'm seeing a trend....:confused: , your results are about what I got on 5 dyno runs with one exceptional dyno run that got higher results, perhaps it was the fluke.....

[MachRc]

really sucks.. mines well over 130k and its still made 90 rwhp bringing my weak 180 to 269.2 on stock clutch 5-speed.

I would of been dissapointed too even though the TS makes power ealier. Hows your torque band? post the graph do0d.

[e34m5]

I would be happy with 270 like yours.

thats a 330 right??? u made 180rwhp stock?

post the dyno

[spartanwarrior]

Well 100+ miles on a bmw isn't alot to lose that much hp period, just incase i misread do you have a auto or a 5sp manual if it's a 5sp what gear did they dyno it, just try to figure out the problem because ess is pretty much on tach with their hp figures, because with my 328 vortech unit running 7psi i made 254rwhp they were right,, now on my 330 TS2 i made 312rwhp,, so i would say your loosing 30hp from somewhere.

[330i ZHP]

I hope your car is an anomaly with this power loss. Or it is some dyno or gearing screw-up.

I heard today mine will ship tomorrow - yay

[Tyler@UniqueDesign]

You measure higher intake boost with more restrictive exhaust and cam combinations. Maybe thats why its reading high, then again you can't say its exactly 6.5 psi, which is why AA was claiming 8.5-9 psi when they released theirs, its not 100% consistent throughout RPM because of back-pressure and harmonics.

Here is the Dyno Graph

[aggieE46]

Have you seen a dyno from anyone in the US boasting claimed numbers? I hear a lot of people saying it's fast, and I've been in a TS2 car that blew my mind, but he's also about 30hp short on the dyno... Probably 25 short if he hits the dyno in 5th :loco:

yeah I was hoping for 190, but with stock everything, 180 @ 130k was

aah-ite


as for the dyno e34m5, you seem to be shhort 25-30hp and torque when I compare to my centri graph.

6.5 redline?

Maybe the claimed #s from ESS were from running with 93+ octane fuel:dunno: too lazy to go on their site to check test conditions.

[330i ZHP]

I was thinking the same thing...not to mention the temperature and humidity up there might be optimal for dyno runs...not sure about 30hp though

[aggieE46]

I'm in TX, my friend is running 93. ESS is helping him get it figured out, though. I'm sure they'll find his power :)

[e34m5]

I don't think it's an anomaly. After talking to a few people I am beginning to belive that there are significant diferences with the US motors such that they do not make the same power.

I don't know what those diferences are but we have always known that US spec engines are never as strong as the european versions.

I was also told by ESS that our ECU's are not programmed as agressively either.

I really would like to see another dyno run from a US spec engine with a TS1.

I spoke to you buddy today....I hope they can work it out...he's none to happy.

[330i ZHP]

If programming is not as aggressive here, than I need to convince them to reprogram that as well...

Thank you for posting honest results for those of us still waiting for our kits.

Here is the Dyno Graph

Were the dyno runs in 5th gear (1:1)?

[330i ZHP]

please tell me this is some error in testing or dyno error

[Asbjorn@ESS]

Well, actually I do not think there is anything abnormal with this dyno. The TS1 is rated at 320hp (272whp) @ DIN standard temperature of 20C/68F. On the non intercooled TS1 it is programmed to start pulling timing when you have over ~77F and a lot of timing when it is over 87F in order to keep the engine safe. This is why we recommend the TS2 to keep the power optimal in very hot climates as the TS2 is programmed with less ignition reduction vs temp due to it's intercooling. There is also a lot less air density when it is ~92F as in this dyno making power drop on both NA, but especially in a non-IC FI car. You are also running 91 octane which does not help either. You did add some octane booster, but I have yet to see this make a significant difference.

The 272whp number (on 93 octane) is however rated conservative, and most Z4 3.0i TS1's dyno 280+whp (~70F) and 330's dyno mid 270's.

We also see that cars with 90.000+ miles normally dyno 10+whp less than a lower mileage car due to oem cats starting to become congested. It is always a good idea on a high milage M54 to replace the cats(or install headers) before FI to make sure you get full benefit of the kit.

Try putting in a pair of fresh cats and redyno using 93 octane in ~70F and I guarantee you that you are up to the 270's as you should if everything else on the engine is operating poperly. If you run 91 octane you can expect mid-high 260's (see reference TS1 dyno).

But even in 92F the TS1 is capable of a 35% power increase on 91 pump and in a high milage car (185whp-250whp) which is not bad considering this is a non-IC budget kit ran under the worst possible conditions.

[Asbjorn@ESS]

I spoke to you buddy today....I hope they can work it out...he's none to happy.

He has a problem with a misfire in cyl 6, probably caused by a bad injector electrical connection. We have scheduled to send him a tech this coming Monday to sort it out for him. This is most likely not a kit related problem, but we have offered to send him a tech as in this case it is easier for him than to have a local mechanic diagnose it as these electrical problems can be difficult to diagnose without the proper BMW test equipment our techs have.

[Asbjorn@ESS]

And the ESS Euro 98 and US 93 softwares have the same tuning. It is just our US 91 software that is detuned to keep the engine safe with the low octane quality.

[330i ZHP]

Aj - with the TS2 (+) software tuning you are doing for my setup - what will mine have from above? Will mine have the more aggressive mapping? I want as much SAFE HP from this thing as possible.

[e34m5]

Asbjorn:

Please understand that I really like this kit and have nothing but praise for ESS, their support and work.

The issue for most of us is one of expectations. We expected, based on published data, to have somewhere around 280 - 290 whp. We are geting 250 - 260.

No where has it been explained that the published values were obtained in absolute optimal conditions, meaning that those values are not realistic for most cars. With a vast number of the population in the US living in warmer climates, and 90 to 93 octane fuel, then this should be made very clear,or perhaps a new set of numbers published.

I am not sure whether or not I would have done this knowing these results, or maybe I would have done TS2 right away. The work to upgrade to TS2 now, albeit not extremely difficult, is way to time consuming.

BTW, I am running 93 octane which is what is mostly available in the US.

If there are any other suggestions I will be glad to try them,

Thanks.

Like they said you cat's clogged and honestly come not **** they are going to post it in optimal conditions thats a common sense deal here. Either way good luck.

[e34m5]

I spoke to some one with new cats....same results...

[thekubiaks]

I've had both the VT1 and the TX2 superchargers. Here are the results of all my dyno runs. I have the sheets if you really want to see them.

VT1 - HP 227.4 / TQ 213.7
VT1 - HP 239.8 / TQ 217.3
VT1 - HP 237.8 / TQ 214.4
VT1 - HP 248.2 / TQ 223.7
++++++++++
TX2 - HP 242.8 / TQ 223.7
TX2 - HP 283.7 / TQ 258.1 ***

*** I removed the valve in the air intake which opens and closes around 4000 rpm's to aid low end torque (forgot the correct name of the valve but thought it was restricting air??) Also, got the latest software from ESS that allowed the removal of the 470K resistor in the MAF wiring. Since then, my idle has been flawless and power solid.

Perhaps the 283.7 HP run was a fluke, (a sudden gain of 40 RWHP ??? :hmm: ) perhaps it was not, my car is very fast above 4000 rpm's and I've had an ESS supercharger on my car since 12/02, that speaks well for durability. Also worth mentioning, Asbjorn at ESS has always gone out of his way to help with S/C issues.

I can only speculate about the original post of 250 RWHP with the new TS1 S/C. Heatsoak on the dyno will cause a big loss in RWHP. One last thought, if the TS1 is putting out 6.5psi and my TX2 is putting out 8psi, theoretically, the TS1 car will make less power than my 8psi car. It's just the TS1 design allows earlier boost (higher torque). If I lived anywhere near the West Coast, I'd take my TS1 equipped car to ESS in San Diego or Los Angeles?? and have them mess with it until they got the RWHP numbers they claimed.

[e34m5]

Unfortunately I live in Georgia. I have high praise for Asbjorn and all the ESS guys. They have always been very accomodating.

I guess I am more bummed than anything else. Not bashing ESS in any way.

Your numbers seem to support the fact that 250 may be all we can get....

I just wish that I had known about this sooner, might have thought harder before making the investment.

[bigjae1976]

Patience is the key!

Asbjorn,

How much of a HP and TQ difference is there between the US93 and US91 tuning?

[e34m5]

Agree.....

IF we can get more then great....if not so be it

[e34m5]

New CATS are $1600. Can't by used ones because EPA will not allow....

I don't think I am willing to pay that much for this.....:(

[EIAlfonso]

Was your ECU mapped for 93 Octane?

[e34m5]

Yes...mapped for 93 octane...will wait for your results...

[david05111]

Why not go catless? You live in Georgia where there is no inspections (or at least I don't think there is)...it might be a little louder, but who knows...it might be to your liking. Not to mention that you will make more power because its less restrictive...

I have a great deal of respect for ESS, but this is probably the reason I'll go AA...I like having the shop that built the thing right around the corner so they can diagnose these problems in-house. ESS get a shop over here and I'll be glad to consider you guys any day of the week...

[spicytuna]

put some race gas in and crank up the boost, doh!

[e34m5]

Georgia does have emissions inspection....otherwise I would have ripped them out a long time ago.

Can't find 100 octane gas anywhere around here.

[aggieE46]

Yikes! For much less than that you can buy headers and high-flow cats (there's an extra few horses for you :idea: ). Of course, you may have to get your hands dirty.... I know BMW owners HATE doing that :rolleyes:

[bigjae1976]

I thought ebay headers and random tech cats would run you less than $600 plus installation?

I've seen about 6 hours quoted to install the headers. You should still be well under $1.6kl if you go to an indy shop with reasonable rates.

[e34m5]

I have done all the work on my car with the exception of clutch/FW.

I have spent all morning scouring for used CATS, but so far nothing.

Who makes aftermarket headers for this application?

[Asbjorn@ESS]

With high milage cats this is always the #1 place to look for hidden power.

The TS1 is not engineered to perform optimally in weather over 87F, it is engineered to keep the engine absolutely safe in these conditions. We can obviously change the programming to give you more timing in hot weather, but this is on the expense of safety. I would say that the TS1 on a 330 (Z4's always seem to dyno 8-10rwhp more than E46's, both stock and FI.) with 80-87 weather you can expect mid to high 260's at the wheels. Over 87F you can expect high 250's. TS 2 will also loose power when wheather is over 87F, but not as much as the TS1. This is the fact with any kind of forced induction, heat is your worst enemy. The only way to counteract and make good power with very high temps is high octane fuel or lowered compression.

A TS1 rated to 272whp on a Z4 3.0i using 93 octane fuel in 68-77F can however expect substantially more than rated power (280+ whp normally).

[e34m5]

Ok...I understand. Perhaps it was my fault for not asking the right questions before purchase.

I am looking for CATS but so far nothing.

[douglas_ngo]

I guess it depend on where you live in GA. Where I live, I don't have to go thru any kind of inspection. I am running without cat on my pickup truck. Actually, the cat is still there, I just remove the honey cone material. It would pass a visual inspection.


Georgia does have emissions inspection....otherwise I would have ripped them out a long time ago.

[e34m5]

Well, they use the OBD por for readings. If you refer to the tail pipe sniffer then it depends on the age of the vehicle.

Last I heard GA agreed to emmisions testing so they could have access to federal highway funds.

[LAFENGAS]

No where has it been explained that the published values were obtained in absolute optimal conditions,


you're never going to see company advertised 0-60 times posted for any car that performed the test during a snow storm on ice either.

when posting optimal results, you're going to expect optimal conditions.

just my $.02

[e34m5]

Well I guess that's the problem with advertising. However, some disclaimers should be noted.

At any rate, I think I have all the info at this time. We'll wait and see how it all comes out.

Maybe others will post dyno results for comparison purposes.

[spartanwarrior]

I don't think I am willing to pay that much for this.....:(It would be cheaper and wiser to buy Headers and then install 2 americats under the car.

[aggieE46]

Maybe I don't understand your application. I guess I assumed this was in an E46. You don't have anything in your "garage". If it is an E46, there are many header choices available. Ebay headers are cheap and they work. Technik gets my vote. I'm trying to pick up a set of the Gen. 3s right now.

If you installed your TS1, I'm sure you wouldn't have problems with the headers. That'll save you a TON right there.

[aggieE46]

Sorry, I just managed to read the thread title. You have tons of options for headers. Cats can just be welded in, along with new O2 bungs. They'll just move further down the exhaust path. PM me if you can't find info. I have some threads bookmarked with examples.

[Activ3]

I guarantee that if you see a picture of the factory exhaust manifolds on the US spec e46's, you'll be ordering headers asap.

They are the ugliest headers, ever. lol

[Asbjorn@ESS]

:werd: The ugliest and seems to be the most restrictive. They look like pancakes at the exhaust port of the engine. :(

Absolutely, but as long as they are relatively low mileage (less than ~90K normally) they still get the exhaust out without to much backpressure, it is when the cats start to get congested you really loose power.

I tested my personal TS2 Z4 3.0i with stock manifolds and exhaust (~33.000 miles) and made 308rwhp, then switched to Alpina headers and CSL cats and made 311 so the difference is not huge unless the OEM's are congested. I loved the header sound and it certainly "felt" faster, but I only gained like 3rwhp @ 8PSI. Now if you try to move more than 300'ish rwhp through the OEM's the headers will gain more and more over even a pair of fresh manifolds as ~310rwhp seems to be their saturation point.

I then added the FI cams and 8.5PSI TS2+ upgrade and made 344,73rwhp.

[Asbjorn@ESS]

Wait till next week and I will post my dyno. I also changed my headers, we will see if I make the published hp.

The fans in our rating dynos are off and we take into consideration not optimal conditions during kit rating. That is why the TS1 is rated at 272whp even if several of our R&D and customer cars (especially Z4's) have dynoed in the mid-high 280's. We do however not rate a non-IC kit at 92F ambient as this would not make sense since most customers would get a lot more power than this rating under normal conditions. A decent condition TS1 330 would under virtually all conditions where the temp is below 80F make the rated numbers. It would be very close up to 87F and 6-10% lower at 90-100F as a function of both heat and programmed in ignition retardation at high IAT.

[aggieE46]

Yup. The first time I saw a pair for sale in the classifieds, I decided that they had to go. Just need more cash...

I dynoed again today, I will be start a new thread about my adventures shortly, but the power problems I was having with my kit was due to the hoses being incorrectly installed. My intake manifold was not receiving any coolant and thus my kit was acting similiar to a TS1. My best numbers were 303hp and 276 tq. Many thanks to Asbjorn for coming out here and troubleshooting my car. I will start a new thread with my issues and solutions when I get a chance.

I just looked at the dyno posted on ESS' website and it shows 321rwhp/286tq on a Z4. I think ESS said that Z4s dyno a little higher. So it the 18hp/11tq difference on par with what the kit should be at taking the weather conditions into account?

He has headers and an exhaust so shouldn't it be closer to the 321/286?

The TS2 kit is rated at 350HP (297.5whp) The 321whp dyno was a development car (Z4) under good conditions (67F and 16.000 miles on it) just showing what the TS2 kit is actually capable of on a stock motor in good conditions. Based on several R&D Z4 dynos we could have rated the TS2 @ 321whp/377,6 crank, but in order to get these numbers out of a TS2 you need a fresh car, chilly weather and good fuel. This is why it is rated at a rating it will meet even on a high mileage car in hot weather. That way we do not disappoint anyone, and if it makes more whp than the rating nobody usually complains..

You should expect 297.5whp @ 68F with the TS2, headers makes very little difference over a pair of fresh cat-manifolds at 8PSI without cams and when you get 303whp @ 84F that is actually considerably better than the ratings. Especially on a 103K miles car.

It was a pleasure meeting you Elio :hi:

This is why it is rated at a rating it will meet even on a high mileage car in hot weather. That way we do not disappoint anyone, and if it makes more whp than the rating nobody usually complains..

You should expect 297.5whp @ 68F with the TS2, headers makes very little difference over a pair of fresh cat-manifolds at 8PSI without cams and when you get 303whp @ 84F that is actually considerably better than the ratings. Especially on a 103K miles car.

It was a pleasure meeting you Elio :hi:

Thanks for the info...I understand much better. I got to ride in Elio's car the day before you got there. I would have waited but I don't think the Army would have. I was still impressed with the kit while running as a TS1...can't imagine what it feels like now.

why does a stock z4 3.0 makes more then a stock 330 ??



i read somewhere in this thread, i could be wrong... :eek:

I'm no expert, but here's what I assume... To the best of my knowledge there is not much difference in the engines themselves so I would think that they would both perform nearly equally at the crank. The difference (in my mind) probably comes from additional drivetrain losses incurred in the 330. Could be the result of a longer/heavier driveshaft, diff, drive axles, wheels, or a combination of all four plus some other variables between the engine and the dyno.

I think the Z4 also has an electric steering pump...:hmm:

[MarvelPhx]

From what I have seen, the differences to a Z4 from a 330 are the Z4 has electric steering so no drag from the belt-driven power steering pump and a non-vacuum compensated fuel regulator. It also probably has less drivetrain loss. Every Z4 ive seen makes more power than my 330i did stock. Bastards. :)

Its true Z4s are faster than there 3er counter part. I have 05 Z4 2.5 5sp and I beat a 04 330i. I mean we had a few runs a friend of mine and I took him every time by a few cars. And this guys Auto X his cars quite a bit. Its stock for stock.

I think its alot to do with the minimal drive train loss, my car feels like it makes more TQ when I don't odd. I love it.

:thumbsup: Way to go Elio on your TS2!!!!

I`m looking forward to your story too.....there are lessons to be learnt i`m sure.
Also good to hear ESS giving their total support for the Totally Screwed Club!!
If you ever want to fly to Sunny Wales Asbjorn, i`ll put you up for free board and breakfast.......:)

Asjborn,

How can I check coolant is running through the manifold? The pipe at the back is always warm...

Regardless if the car is faster (lower weight of the Z4 could do that), I think we are referring to the actual power output between the two on a dyno.

I checked this myself. After a good run, feel the hose connections on either end of the heat exchanger up front. One should feel warmer than the other. If both sides are the same, you are not flowing correctly.
