TT Stage 1 is installed Dyno'd and runs great!!!!

**Colo97M3** · 07-13-2005, 12:56 PM

Well after a few snags (one bad turbo) and a mechanic with the learning curve for the BMW world and FI, I finally have my car back and it is running great! Dyno'd 318 rwhp SAE at my elevation of 5600 ft. That was with 8 lbs boost. He was having trouble getting a good torque reading, so not sure what it is yet. Anyone out there with dyno knowledge know the best place to tap in and get a good torque reading?

As far as driving the car goes, it is amazing!!! I love the sound of the turbo spooling up and the sound of the blow off valve!!!! Big grins!!!!

I do have an issue with the AC though. When stopped in traffic it gets to be warm and eventually HOT air. I also loose cool air when I am getting on it. It has been 100 degrees here lately, so not sure if it is jsut having trouble keeping up, or if the intercoooler is blocking the airflow now. Has anyone with a turbo'd E36 had this problem? When I am moving at normal speeds, it is fine and cold. It also seems to be not as cold when I turn on recycled air??? which is always colder......

Thoughts??

Congrats on getting the kit installed! Ill def have to check the car out next time I see you. Nice dyno numbers for this elevation too.

**poohlvhun** · 07-13-2005, 01:07 PM

Congrats!
I think computer cut off a/c on full throttle.
How long did u wait to get the kit from nick?

**NickG** · 07-13-2005, 01:10 PM

Definately good dyno results considering the elevation (170rwhp NA uncorrected, 277rwhp 8psi uncorrected).

Regarding the AC, is the electric fan turning on when the AC is turned on? If so, maybe the system wasn't recharged enough (or properly) after the new line was installed.

**Z3speed4me** · 07-13-2005, 01:11 PM

318 rwhp...what would that equate to at sealevel??? and was it a mustang dyno or dynojet??? anyhow congrats on the install...how was tuning done anyway?

**ADVANT123** · 07-13-2005, 01:29 PM

318whp is what it would equate to at sea level. The car dynoed 277whp uncorrected. Many people believe that the SAE correction doesn't make up for the elevation change though.

Nick, is the A/C system changed with the installation of your kit??

One line is replaced to make room for the 3" inlet pipe. The new line is included with the kit.

I'm one of those 'misbelievers'. That's why I mentioned the uncorrected dyno results in my post. Getting an accurate conversion from high-altitude runs to sea-level is hard enough. Then throwing in variables like the addition of boost makes it damn near impossible.

In my mind, eliminating variables makes things easier. While using uncorrected numbers (from tests done on different days) isn't ideal, at least it eliminates any possible error caused by the dyno's inability to compensate for boost changes.

Bummer, so the system has to be recharged after the install?

Yup.

**Z3speed4me** · 07-13-2005, 01:42 PM

ooooo i dindt see that he put SAE, so 318 about at sea level...nick whats the max some1 has gotten out of your stage 1 so far, 340ish??

**BlownM3** · 07-13-2005, 01:53 PM

318 seems a little low for 8 psi even at see level. There are s/c superchargers making that kind of #'s on 8psi. My RMS kit on 8# made 317 rwhp. Turbo should be more, no drag and full boost througout the rpm range.

Juker is making 368 on the stage 1 kit and I know he is still on the S52 manifold. I dunno if there is another TT Stage 1 higher than that or not.

Edit: beat me to it

Congratulations!

He has to take off the spark plug cover and tap there.

Yup, I agree.

Actually, if you take a look at Colo97M3's NA results, shown here: http://forums.bimmerforums.com/forum...d.php?t=366262

He got 159rwhp uncorrected (I was obviously mistaken above when I quoted 170rwhp), which the dyno corrected to 220rwhp. That's a whopping 38% correction factor!!! (which I don't believe).

So if you take his uncorrected post-turbo results, let's lowball it at 270rwhp, and use the same correction factor of 1.38, we get 370+rwhp (which again, I don't believe).

If you compare uncorrected to uncorrected numbers, you'll see that the car is making great power *for the elevation that it's at*.

**Z3speed4me** · 07-13-2005, 02:19 PM

wow 368 is pretty damn nice for the stage 1...

so all the guys that get your TT kit send their cars to florida huh? geeze i wish you were closer up north for next year...

Nope....the vast majority have been installed by either the car owners or other shops.

**Z3speed4me** · 07-13-2005, 02:48 PM

i guess the part that confuses me is i know u are insane with the tuning...but how do you do it without the car in your hands??? each car is an individual and must be dealt with differently, so the part i dont understand is how you do that, i guess i got lost somewhere in the past like year when this was explained sometime...

<---- feels like an idiot right now

**Colo97M3** · 07-13-2005, 02:50 PM

WOW! I go to lunch, come back and 19 posts! Yeah I was a little let down at the 318 SAE, but Nick said it was great for my elevation. I still want to know what it would put out comapred to Nick's test vehicle in FL that got 343 rwhp. The Dyno is a Dyno Dynamics from Australia which I guess is always a little on the low side as well. I would say the 318 is very conservative.

Correction too on my NA numbers it was 170rwhp uncorrected, not the 159 I posted originally. So went from 170rwhp NA uncorrected to the 277 rwhp uncoreccted at the 5600 ft elevation here in Boulder.

So Nick, as for my AC, how would I know if it was fully charged correctly or in-correctly? With this heat, it sucks for it to stop working when I get to a light.

Nick, So the correction from 170 to 220 you don't believe? Too much of an increase? That correction factor is something to do with the elevation here right? What do you think it should be? I was thinking when I got this kit and had the S50 manifold already that I would have corrected numbers at or a little above your test vehicle of 343 rwhp. I was using 91 octane on 8 lbs boost, you said yours was 93 octane at sea level with 8 lbs boost right?

**Z3speed4me** · 07-13-2005, 03:03 PM

well 93 octane will obviously pull more power then 91...like race will always pull more then even sunoco ultra 94...

higher octane allows for more headroom in tuning to bring out the power,

so 318 on 91 octane at 8psi, then compare that to 368 on 93 octane at 9psi.... I can see that, but then again the 318 is a little sketchy (because of big correction factors) and hard to make a comparison as Nick stated.

Could you post an image of this line?

Did you reverse engineer the DME code yourself?
