My Ride: 03 ZHP AA Stg II
In Vegas for a few days work and haven't had access to a computer. Talked with my guy at the install shop and everything is about done. Just got an email from the AA/UPS guys that my ECU is in transit and will be in Nashville on Weds. I'll be back in Nashville on Thursday so I should have a report by the end of the week. While I was on the phone with the install guy he had to run because they were going to pick up their Dyno for the shop. Hope to have a dyno run or two in the next week or so as well. I'll post the results.

The whole process has run very smoothly so far and props to AA and Karma Performance Engineering in Nashville.

In regards to the install price, I'll tell you when it's all said and done. Don't know the exact charge yet. Also, I haven't upgraded my clutch. Plan was to feel her out for a bit and potentially upgrade the clutch and rear diff after driving her.

In other news, I did the Richard Petty Nascar experience at the Vegas speedway on Sunday. Wow is all I have to say. One of the best things I have ever done. Guess who got best lap time?

Sorry for the delay in the update. Finally got the car back on Friday afternoon last week and went out of town for memorial weekend. I got to drive her on the interstate for a while and am very happy with the results. I can notice improvement in the lower portion of the rpm band, but the real difference is after 4,500 rpms. She really starts to scream. I'm very pleased with how smooth she accelerates. 3rd gear on the interstate if a lot of fun. 55-95mph takes no time at all now. Couple of things that were a little different that what I expected:

1. Sound of the intake - The intake can sure pull in some air. It's pretty loud at idle.
2. Blow off valve - love the sound of the blow off valve. Louder than I expected. The combination of the intake and blow off valve would scare the s**t out of some person walking by after a rev. Sounds like a jet engine taking off.
3. Traction - actually suprised how much traction I have with my 255 mich ps2's. I haven't launched her hard yet, but she doesn't have any wheel spin just running through the gears.

I don't have my boost guage on yet, but will shortly. Also, the plan is to have her dynoed this week on a dynodynamic at Carma Performance Engineering in Nashville. I'll get her cleaned up and snap some pics and videos.

AA's dynojet showed 330 whp on a 330i. Since my car is a ZHP and I have the AA exhaust on it. I was thinking somewhere around 345 whp on mine.

Here's a photo of her I took in my work parking lot. She's still dirty. I'll get some nice photos of her soon enough. Been really busy lately.

Had some issues with the belt and finally got them resolved. Not going to get into that though. Got it dynoed on a Dynodynamic yesterday here in Nashville. It was about 85 degrees outside and I put down 291rwhp. Using this http://www.to4r.com/calcs/pwtq.php conversion, looks like I'm around 342rwph on a dynojet and 398 at the crank. Take the conversion for what you want, but using it for a general guideline since AA measures their kit on a dynojet. Don't have the graph but hope to in the next week or so.

This is a AA C38 Stage II kit with their cat back exhaust on a 6speed manual ZHP.

60-120mph is pretty nasty.

Closest 1/4 track is an hour and change away. I'll get up there at some point. The launch is pretty weak without the LSD though.

Think I should be able to outrun an m3 now? The car feels faster on the highway than my father's 996 911.

Stock m3s dyno ~270whp on a dynojet, you should pull them pretty hard on the highway. I'm curious as to what you'll trap at the strip, possibly 110+ if you can launch it decently (2.0 60ft or so). Do you have headers? If not, I'd definitely suggest them, your stock manifolds are very restrictive with the power your making now.

I wanna get headers. I already have the AA cat back exhaust. The issue with headers seems to be passing emissions. I need to pass emissions and don't want a super loud car. Any sugguestions? I'm all ears.

The other issue with headers is finding a method to reliably prevent CELs. Non-foulers seem to be the best current solution but too many people still seem to report an occaisonal CEL for me to consider going this route. If anyone can come up with a guaranteed CEL free solution, I'd love to hear about it.

one of the best mods on these cars is the header upgrade, You will find that the headers will give you such a nice top end power band that the cel light wont matter.

As for emissions you will need to know someone that can help you out there for the paper work if you know what i mean. (same car on the machine and he's your paper work sir lol) shhhhh

you will come around soon once you are used to the power and crave more.

Your numbers are off. You are probably putting out 360 max to the crank. I am not convinced that there is a 15% loss with a dynojet either. I put out 310 on a mustang and was even with a m3 that put out 278 on the same dyno. My car traps at 106 mph. 1/4's in low 13's. I would imagine that you would trap around 104 and a mid 13's time. Most people seem to hopelessly optimistic about the times they will run and the power they make. Also, keep in mind that a M3 has a 20% higher gear ratio and that multiplies the torque that they put down.

I have done over 50 runs on the strip and 50 or 60 pulls (from 50 up) against various m3's (with a 5.5 inch pulley) and we are dead even (I do have the stock gears with a LSD). I am going down to a 5 inch pulley and should pull comfortably. I also have cam's, custom intake, headers, racing cats, exhaust and weigh 3218 lbs.

Just enjoy your car and be happy that you are as fast as a M3.

I think your gearing may be limiting you quite a bit... have you considered putting in a 3.38 or 3.46? Even if its an open diff, you could try it to see how much of a difference it makes against one of the M3s you've raced.


Also, keep in mind that the OP is on close to 11lbs I believe... 34Xwhp makes sense to me.

He will need to be a lot more than 11psi to get to 340 whp. With all my mods I am at 310 on a mustang (which reads lower than a dynodynamics). Sure with a 3.46, I multiply my torque by 15%, lower my fuel consumption by 15% and rev higher on the highway. Keep in mind that I also have a lot of weight reducing mods. In any event I am happy with the power my car makes. There is always a faster car. I just think the OP is not being realistic. My .02

I guess we'll see if/when he gets to the strip

Also I'm pretty sure that the dyno dynamics reads lower than the mustang, with the dynojet reading the highest of the three.

Dynodynamics reads the lowest from what I understand.

Edit... AA posted dyno for their stage two is like 330 whp on a dynojet. I think it makes sense to have a bit more than that when I have a zhp and aa catback exhaust. But who cares about numbers. I know the car pulls hard and that's what matters. Found the perfect place to top her out. Got a buddy with gps mph too.

Dyno Dynamics do read very low. My old WRX made 345 whp on EngineLogic's dyno dynamics down in Houston, TX. I was able to pull an 11.6 @ 115mph with it.
