Ummm....Actually I'm pretty sure I am the only one in here that has built there car, and so everyone knows....its a total TURD!!!! I ran a 14.1 @ 104 on 6 psi.
Don't worry though. The wife has said I can get another set of tires for it so I don't embarrass myself again at the track. :-( But as you know, being a high school physics teacher doesn't pay much so I'm still saving up!
Anyone want me to tune there AEM or autronic or Tec3r so I can make some money.

Here is something else to think about.
All exhaust flow calc's are calculated at a 25" of water table flow sheet......so
Now assuming a proper test at 25" of water then the most any 2.5" Pipe could flow, even if 100% efficient, is 138 x 4.9 = 676 CFM. A perfectly efficient 3" pipe could flow 138 x 3 x 3 x pi / 4 = 975 CFM.
A stock EVo comes with a 3" maf. I would assume then with the small restriction of the maf, the max flow through a 3" maf would be around 950 cfm give or take.
What is then the max HP one could make assuming you still have the 3" maf as a restriction?
How about someone else take over here and calculate the hp you can make with 950 cfm assuming 90% efficiency on a VE table.

I also love the Orange and I think I know someone that wants The Orange done to a set of wheels if its Exact or Really close Wow this is Crazy I take a 3 hour nap and come back and there are 3 new pages of this argument
I going back to sleep now 
Yeah, I did build my car and had Courtney Green tune it......
Looks like you should of stuck with Porsche's then...

I tried doing it but I failed. So what is it and how do you do it?

man these idiots are buggin me talking about j's car. one of em dont even have an evo 
i just cant wait for stuff to go down and everyone have their head up there a**
people are just ddb (deaf dumb blind). anyway if your reading this get back to work tell bb hey talk to you tomorrow.
