ESS Supercharger Kit Dyno Chart for 2002 330 CI

I have a 2002 330 CI (5-speed manual) and have ESS Tuning's supercharger kit. This is the only engine modificiation I have. It's well below the 335 hp at the crank (271 rear wheel hp which is less 19%) that ESS claims. Although I'm quite pleased w/ how the SC performs and feels, I will be contacting ESS about this. I'll be adding the UUC exhaust in 2 weeks and should gain another 8-10 hp (exhaust gains are higher for forced induction systems). Until then, let me know what you all think of these numbers.

FYI, a stock 330 CI has 182 rear wheel hp, and a stock 2002 M3 has 272 rear wheel hp.

Do you know what the stock torque numbers are at the wheel ?Because that looks pretty good to me about 200ft lbs at 2500rpm should really pull from down low in the rpm range. I bet it is a blast to drive now Don't have to much fun, and I would contact the manufacturer if their numbers don't match might just be something minor.

im confused... i thought a stock 330ci makes 200hp at the wheels... so you only gained 26hp from the SC?

Is your car auto, or manual?

Mike had his stock 330 dynoed at 199 hp at the wheels. It should be putting out more than just a 26 hp gain at the wheels.

stock 199 at the wheels?! Doubt it!

I've seen over a dozen 330 CI dynos and have "never" seen one over 190 hp. It's not that I don't believe you, but that must have been an anomaly. Was that your average of 3 runs or your highest of the 3? Also, what dyno did you use and can you post your chart or any data sheets? I'd like to see them. Thanks.

Yeah, the numbers could be better (I was hoping for 45 more rear wheel hp). I will tell you this though even with my current numbers, my car is still much faster than most cars out there. On the highway, it kicks ass! I can get from 80 to 120 mph in about 5 seconds and keep up w/ the 2002 M3s. Being 300 pounds lighter (2 passengers) than an M3 makes a pretty big difference. I'm still waiting for ESS to respond to my stats. If anything, I believe that it's the software that causing the lower numbers. The blower itself can work efficiently all the way up to 20 lbs. of boost which is around 680 hp! I'm a patient guy and willing to wait a couple of months to get my car up to where I'd like it. Until then, I'll continue to enjoy my ride the way it is.

However, aesthetically, the install is first rate...the extra power reveals itself instantaneously no matter what gear you're in. My goal is to get my car up to 275 rear wheel hp w/ the equivalent or more torque. Once there, I'll be able to handle most anything out there, except for the Porsche 911 twin-turbo.

hell even if the 330ci is dynoing 190hp to the wheels stock, that SC is still only geting about 36hp gain. Kinda weak if ya ask me.

Isnt the SC and install like 5k?? More power to ya for doing it. But for 5k and getting a 36hp gain to the wheels it not worth it to me. But then again maybe the SC is being restricted since thats your only mod? lets see how bad ass it can be when you add some other bolt ons.

Not sure if you are talking about automatics, but manual 330s are right around 200RWHP.

It seems like they may not have upgraded your ECU.

how long

how long has it been since you got the SC installed?
Right after I installed mine, the sc didn't give a lot of power, but it gradually picked up after a few hundred miles as the ECU learned about the blower. (I have yet to do a dyno' )


I'd say you should wait until u got 500 miles on the SC and they dyno' it. If you already got 500 miles before u got the dyno, i'd say contact ESS

goodluck!

Hi VAFunkie, actually I already had about 700 miles when I got it dyno'd so I think it should be okay. I'm wondering if the DSC makes a difference. I've heard that DSC should be fully disabled before you dyno. I'd certainly like to see your dyno's when you decide to do it. Thanks.

YES, the DSC is supposed to be completely disabled. That should make a big difference.

My friend Ta's 330 with the RMS supercharger (YEAH YEAH RMS HAHA!) had the same DSC/EML problem. But that was before he had the completed software. He then had his car redynoed at evosport and was pumping out 275 HP at the rear wheels. But there was another problem in the high RPM band so the car's software is being retuned and he will be installing an intercooler (not a front mount). After the retuning, the car should reach or get really close to 300 HP at the rear wheels.

maynardc, the exhaust should help quite a bit.

Hey JetBlackE46,

I hope you are doing well buddy. I'm not sure if the updated 323 software came out yet but the new version should have the 6500 rpm limiter removed and it should solve the check engine light problem because Ta's new software fixed those problems.

I'm sure you must be really frustrated with RMS by now because I read about your ordeal. You should contact them and let them know, again, that these problems haven't been solved. That damn OBDII is just so complicated. I know you have been patient with Osh and the guys at RMS but I think they are getting closer and closer to getting it right, I hope.

Also, if you want to get someone else to tune your SC, you might want to ring up Samir or Evosport. I know Evosport is working on an SC for Danny's killer 323 and I know Samir knows a grip about engines. Maybe too much They should be able to help shed more light.
