Exclamation AA e46 M3 SC update....**spy update**

you didn't hear it from me, but here is the latest on AA's SC for the e46 M3...

I was hangin out at AA with my boy, who is an AA insider (sorry, but he remains anonymous), and as we went there to chill for a minute, I see Karl and Co. wrappin up another day of testing and tweakin the red M3. They take a long break and what not, so I venture my curious ass onto the scene, and low and behold what do I see:

the fresh of the press Dyno, showin 354 hp !! That's right boyz and girlz, that's 354 ponies to the rear wheels!! Take into account that it is a mustang Dyno, and you can easily figure this sh!t out... They walk back and we get to talkin, and I told them that I couldn't even hear the SC spin, and asked how much boost are they running right now....here is the kicker:
5 psi of boost!
So, some more talkin and he tells me that their goal is to put around 13 psi, so that's around 450hp to the wheels... INSANE!! I got to see some of the other dyno prints, and at one point they did have an 8psi run, poppin a whoppin 396HP, but they the maps where not running so smoothly so they backed down, until they get all the kinks out.

Don't know about havin 13psi on an M3 engine, but I can tell you that with 5 psi that sucker has been running Dyno run after Dyno run, and no problems yet, pushin 350+ to the wheels... Figure that they can tune it safely to around 8psi and you got something coming!!

remember: you did NOT hear this from me!

First of all.. this new forum kicks azz..

Secondly.. good info!!! I am still worried about reliability. I hope they run this car for a good 4-6 months and open up the engine to see if there are any signs of wear..

The I was told was under $10k. Dinan at the same time is developing one in direct competition with AA Tuning. And NO BMW DOES NOT warranty a DINAN SC. Only Dinan does.

I'm sure they're going to be testing the durability of it for the next 5-6 months as well.

354HP x 1.15 (15% for drivetrain loss) = 407 at the crank. That sound about right?

the saving account was opened yesterday for the SC for the M3.... its scary that the M3 already has this kind of power, I can't imagine it with even more... I think I would go through a set of tires a month!! Oh well, its well worth it!!! Keep the *spy* updates coming!!!

pretty close....I think the mustang dynos are around 17-18% loss, so I believe it was morea around 415hp or so

Actually, it's more proper to divide by 0.85. (354 / 0.85 = 416)
Drivetrain loss is 15% of crank, not 15% of wheel HP.

On the E36 models, AA uses a 1.31 correction factor. Not sure what they use on the E46.

Multiplying by 1.31 is equivalent to dividing by 0.76. What kind of drivetrain has 24% loss!?
