im so excited to see this, im about to pee my pants
aw.. only two tiny lil revs... :(

[TeKNiC330]

When will it be out??

BOV??? :yikes:
Sounds badass!!!

[russ330]

That sounds damn nice. It sure would be nice if I could get my ride to sound like that. :drool:

[KromeX]

Doing more testing right now. I just went for a drive and there's so much torque, I'm spinning the tires at 60mph with Nitto Drag Radials on. Must be this cold weather.

[e_one09]

Man, that's awesome.

[Bezita]

me want one........... :drool: :drool: :drool:

[Presns323i]

is that a blow off or bypass valve?

[russ330]

So when can we expect serious details about this kit? Pricing? Approx. installation costs? Release date? What other drive train components should we think about upgrading with the kit? 0-60 & 1/4 mile times...

is it applicable for 320i? :eeps:

[bigjae1976]

Where do you get one of these?

[m3on20z]

go to their website...i posted ^^...i think you can buy it now...

[wust]

Can we just buy stage I instead of stage II? no price for stage I. is it $3995? i don't see the place to make a order, maybe i need to call them?

[328iSC]

Is this a DIY kit? Or will it have to be installed by ATP?

[Dalton]

o god im so scared...

Will the stock trannie handle this much power on a 323i? Cant wait for this to come out. What are they doing for the the ECU programming? Will we have to send it out APT? Still alot of questions im sure everyone wants to know. I wouild definitely want this to be stable before buying it.

Sounds great :thumbup:

[Dougs325]

...Let's see what that SRT-4 can do now...haha! God I love turbo's, and there is absolutely nothing better than a turbo BMW! hell yeah! As soon as I get the money, my lil 325 is gonna be forced :-D

[cowmoo32]

MMMMMMMMMMMMMMMMMMMMMMMMM blow off valve...............

Being able to spin the tires doing 60 would be nice too

[gokcer]

So whats it the total cost for this inculding all the other non-engine stuff like tranny?

I know stock clutch cant handle it so I guess add 1K for new clutch and what else?
Can stock Diff & tranny handle this?

[sheefo2k]

omg. omg . omg..
this is toooo much for me...

this is jsut SEX

[gokcer]

How many Turbos do I need to keep up with the Viper GTS I drove last week? hehehe 174hp to 450hp?

[Straz M3]

Ohhhhhh that sound is amazing...I might consider this when the time for FI comes...

Can a stepronic handle forced turbo induction. if so, im starting to save my pennys, screw rims!

[g2go1818]

More info please :D

So what needs to be changed.... Tranny, Clutch, Differential....
How much time is involved in the install, does the car have to be sent in?

What kind of gains are to be expected on other model e46's?

Very interesting alternative to supercharger (imo better) :)

[wyu]

:yikes: NICE!

[bimmerchop]

:drool: I must have this kit. time to save up

[BimmerJustin]

I'M IN. I wonder what kind of number's it will put down with a 325.

[andy7771]

for 2.5L owners, atp's turbo will put out 300hp/torque and it's applicable on step

[BimmerJustin]

100+ HP loss from a 330-325 seems quite high to me. And is 300 bhp or rwhp?

[PooAndGlue]

:yikes: :yikes: Are you absoutly 100% positive that this can be applied to a 325i,ci,cic,ix with a step transmision without negative results? If so, HOLY CRAPO, time to get more job applications.

[andy7771]

i'm not 100% sure any force induction on E46 will not cause negative results. atp replied my email with the number, and they said it will be out very soon. so... all i can say is let's wait and see

[Nico3k]

see this thread. http://forum.e46fanatics.com/showthread.php?s=&threadid=131146

i have my doubts about step being able to take it...........



anyone dyno of 325?

[Rated E]

yep, and we all think GruppeM's sound phat. :drool:

Absolutely sick bro, good to see you back around!!! :thumbup:

amazing! gotta love that sound from a BMW.

[cRAzYgUy]

[Jlevi SW]

I saw this thing in person @ my first meet (the one Pat coordinated at Fantasia) and at the time I was a newb. I didn't know what I was looking at, and what's more, I didn't know why I couldn't stop staring. ;) If all this is true, and the other mods involved aren't too too expensive (clutch, gauges, etc etc etc) then I may just be doing this sometime around December of 05... gotta get rid of the extended warranty. So basically, Kromex can eat M3's for breakfast? Wow. I'll be needing one ;)

[KromeX]

Wow, a lot of responses from such a brief video. I'll make a few more of these when I get some free time.

Here's some general info:

With the new selection of Garrett GT turbos I'm doing extensive reliability testing and finalization of the kit. With hundreds of hours on the dyno, I've been fine tuning many aspects of the kit. I want this to be a put it and forget type of kit which is extremely tricky due to the sensitive nature of these cars. I don't want to be held liable by the board moderators for any type of free advertising and I'm only providing updates to the community because this is where I started. If you guys have any questions regarding the kit, simply email: info@atpturbo.com and your questions should be answered promptly.

Thanks for the info but what upgrade did you do to your car before the turbo was install or even after. Also for step owner we can only max 300hp so how will the kit work for us?

TIA,
Charlie

[KromeX]

Pretty much the only thing in terms of the performance would be B&B Muffler, a Stage 3 Clutch setup, and lightweight flywheel. For step owners, a low boost application would work.

[cowmoo32]

Me too...and I gotta get some money.

[AssassinGT]

I'm in love.

But why are there doubts about it holding to Steptronic? I have a Steptronic 323 and This is a very interesting mod.

[Nico3k]

the transmission on the steps were made to the spec power of the car.... putting twice the power/stress on it is not a good idea. if you got a turbo you would need to reinforce quite a few things and it would be a good idea to swap a step for a manual tranny and new clutch to take all that power

[Jlevi SW]

Ok guys correct me if I'm wrong, but I did some calculations. The stock 330 transfers 207 out of 235 horsepower, which is a little over 88%
This would theoretically mean that the turbo'd 330 is only getting 88% of the power to the wheels... which would be 404.3. If true, that would mean..... almost 460 brake horsepower at the crank. Is this possible? 460hp from a meager 235hp engine. That would be DOUBLING the horsepower of the car. Someone tell me I'm somehow wrong?

JL

[K-DOG]

Why is it hard to beleive?? Thats the beauty of a well tuned turbo car....Havent you heard of Lanver Evolutions (2.0 litre) running over 500hp+, rx7's (1.3 litre) over 700hp+, and skylines (2.7) as well as supras (short stroke 3.0 just like ours) with over 1000hp+......

All those cars started at around 280hp stock, and in some cases QUADRUPLED their crank hp.

[RichP]

Guys, I am sorry, but I have to call BS on this turbo kit at this point..

The dyno graphs are showing DOUBLE the horsepower. Very basically, that means the car needs to be moving twice the amount of air, or 14.7 psi of boost (2 atmospheres; and this is VERY conservative). This on a stock motor is laughable to say the least.

Look at AA's E36 M3 stage 2 turbo kits; they run 14psi on a 3.2L motor, and make 360 to the ground; the smaller 3.0 would have to run even more boost to make 400 to the ground. Also note that the AA stage 2 lowers compression to handle such boost numbers.

In addition, I am not sure where, but I have read the ATP kit runs 8.5psi of boost. There are SC'ed cars running 9+, and even they make about 320 to the ground at best with other modifcations. No way is the parasitic loss on a vortech blower that high.

The numbers on this just do not add up. Either the dyno'ed car has more work than the standard kit, or the dyno is falsified in some manner. It is simply too good to be true that a inexpensive 5K turbo is going to include everything necessary to make 400whp out of the 3.0 M54.

(note: Kromex, I am not attacking you personally, just that things about this kit do not make sense)

[cRAzYgUy]

time will tell

[K-DOG]

Rich, I only have a comment about your statement on superchargers. From what I have seen/read, in some cases parasitic loss from an SC can be up to around 50hp (not sure wheel or crank).
BTW, ActiveAutowerks uses modified mitsubishi turbos off a GSX eclipse I beleive....not the top of the line turbo by any means. The ATP kit uses next gen, ultra efficient Garett ball bearing turbos. I do have some doubts about the engine being 100% stock (not even a thicker gasket found in most turbo kits???), but I am certainly not doubting the numbers.

[Nt_loader]

Time to turn up the boost on my SC, I see 400 rwhp in my near future :)

Kromex nice work :thumbup:

[John from jersey]

I'm with you on this Rich. You bring up some very valid points. The graphs that have been posted are very hard to comprehend for even the stock readouts of the 330 tested, let alone the output from the same so called 'boosted only' 330. To put it simple the numbers are not matching up , not even close. Specs need to be made clear here...there is too much conflicting information up in the air to even get excited about this kit. It amazes me how gullible of a reaction the E46 crowd gives to a new, unproven turbo kit, all while being the first turbo kit ever targeted at the E46. Maybe time will tell that it is a proven kit, but as of now ATP has some explaining to do and lots of it...

Is there any buyers that can provide info about this aside from those involved in the R&D of this kit?

[Nt_loader]

Look at the ATP dyno and my dyno with a sc, looks like I have more hp then an M3 throughout the rpm band.

[e46boy]

ok.. besides the mysterious dyno chart and HP claim

anyone noticed that the pricing of 5k is stage II upgrade kit?

so from my understanding of stages, you can't really skip a stage :eeps:

i wouldn't get my hopes up on this just yet until everything has been clarified.

[m3man]

I am a dyno reading n00b, but why is the power/torque curve for the turbo motor so uneven?

And I agree, 405 hp to the wheels is around 470-480 fwhp which seems a little crazy. I question longevity at the least.

[Amil]

is there software for this

I must say I am very impressed with this dyno as well, nice and smooth. Is that from the ASA sc? Looks very good. I keep thinking about trading in for an M3, but now I'm not so sure.

[Nt_loader]

mtfour why would you trade for an M3? If its speed you are after just supercharge your car and wave bye bye to m's as you pass them all day long.

If you want the m for styling, well then thats a different story.

If I were to get an M3, it would totally be for the speed, but now that I see these turbos and superchargers, I'm starting to reconsider. How does your car drive? Have you had any problems with the ASA kit? That's the kit I really wanted. Are you very satisfied with it?

[Nt_loader]

My car drives just like stock, you will not be able to tell the difference until you push the gas, then you fell your head getting pushed back into the seat :)

I am 150% satisfied with the kit, not 1 problem or issue. I could not be more please with the power, performance, and reliability. If you ever in NY area, send me a pm, we can meet up and you can see for yourself.

[4thChirpin]

any m3 turbo videos??

The ASA kit sounds totally awsome. I believe that's the route I'm going to take. Keep in mind, other fast cars I have owned are an 88 Mustang GT and a 90 Trans AM, my stock 330ci feels a bit quicker than both of those, so actually, my 330ci is the fastest car I have EVER been in. None of my friends are into cars at all. So I can not possibly imagine what 298 rwhp & 275+ rwtrq feels like.

[xS3x]

Kromex,

are you running a software for this car? what did ATP use for the engine management system?

I have a 323i step. Does anyone know if it possible to modify auto tranny to handle more power and run higher boost? And how much would this cost?

[ElitistK]

i love the sound of the turbo, but i think supercharger sounds better

I have the same question just my car is 330. Anything can be done besides mannual swap? :dunno: Thanks~

[Jspeed]

i love the sound of the turbo, but i think supercharger sounds better
No thanks. No "whining" for me. :P
Plus superchargers inherently don't have much boost to bleed off when you let off on the throttle so there's very little sound from the BOV.

[Will ZCPM3]

i dont think superchargers have BOV's do they?

[bmwallianz]

Simply amazing..........ATP is able to create a Turbo set up where many other tuning companies have failed. It is almost too good to be true.......we will have to wait and see!! :bow:

[Jspeed]

i dont think superchargers have BOV's do they?
Like I said, superchargers simply don't have enough boost to bleed off between shifts, so they don't need BOV's. However, some people install them anyway for the sound. Of course, the sound is very mild.

Actually all forced induction systems need some sort of pressure release for throttle lift. Most superchargers use a by pass valve instead of an open air blow off valve. I am interested in seeing how ATP managed to make a blow off valve work with a metered air system. I would guess that they are not running it to open air.

I missed this one.

I think you misunderstood my post. Because the supercharger is directly connected to the crank, it does not leave a significant amount of residual boost as a turbo would during shifts. I did not say superchargers don't need any kind of pressure relief. The previous discussion was about the characteristic sound of a BOV and my point was that the residual boost from a supercharger would not be enough to produce the same level of sound from the BOV a turbo would.

[tim330i]

Ok, that is not how your post reads to me but if that was your point it is a valid one.

Tim

[samir@technik]

...The previous discussion was about the characteristic sound of a BOV and my point was that the residual boost from a supercharger would not be enough to produce the same level of sound from the BOV a turbo would.

This depends on the gear/RPM. Like you said, since the supercharger is crank driven, the amount of residual boost is dependant on the RPM. However, I can verify that the ASA makes quite a high-pitched BOV sound at redline (max boost), which would definitely rival the sound of a turbo running the same amount of boost.

Do you have a BOV in an ASA SC'd E46? I thought you have to re-circulate the once metered air by using a By-pass valve... At least that's what I'm doing. Please shed some light! :hmm:

[samir@technik]

We have the same kit, which uses the 2 Bosch recirc valves.
