How much hp with stock ecu and sfac1
you would want larger injectors, and fuel pump, and a proper tune with the SAFC!! or damage may result, but, if you run like 13 psi u can prolly take him. a front mount might be a good idea as well? as well as some beefy rear tires. cause it will launch on you pretty bad otherwise.....
id know from experience
i had s5 t2 engine in a s4 turboII , 3"full ehxaust ,3" intake,boost control set at 13 psi, walbro fuel pump, rtek 1.7 ecu with 720cc secondarys(basicly like a stock comp,but with fuel cut eliminated, and designed to run 720cc injectors) i had a stage II clutch also.
a front mount would help alot to , as well as make that setup ALOT safer, as intake temps are way to high with that much boost though.......

I think the actual limit of the stock ECU, power wise, is exactly what you can get at 8.6 psi....which is where the stock computer cuts fuel.....
the stock computer with an SAF-C....well thats a good question...keep in mind this isn't a dyno.

ok so i know a fmic would help but, I want to keep tmic. I have the safc but not installed and a manual boost controller thats not installed. I need $200 for install and 5 dyno pulls w/ tunning. I'm running 12psi right now but my clutch is slipping so no boost for me right now.

My car dyno'd 240 at the wheels my buddy with a 02 wrx with 220 whp can't pull on me at all, even off the line, 220 on the wrx is about equivelent to about 290 at the flywheel, so that is sti territory. It's all about power to weight.

way better torque numbers and a better torque curve
are you doing this at the strip? if you are all you need is about 250 flywheel and a good 60' and reaction time.
if it is just a freeway pull 250 will let you pull on him easy

Before you try to beat a modded STi, I'd get your car safe... Keep in mind, the kid just dropped more than 30 grand into a car and mods, and you've most likely spent less than a third of that.
Take your time, do the mods right, spend what you need to spend to keep the car from going boom boom (and of course spend enough to make it kick ***... shouldn't cost that much)
About the TMIC... if you're worried about spending a bunch of money on an FMIC, you can always just buy some good piping and front mount the stock intercooler... or get one of those eBay knockoffs for 90 bucks, they should deal with 13psi just fine.
All in all, you'll be annihilating him for a lot less than what he just dropped for that STi. Plus, you'll sound better. STis sound lame. :P

I thought STI's were supposed to be running more in the lower 13's stock at a track, right there with like Evo 8s? I've also come to understand that a TII runs like 15's stock, what all does it take to get a TII into the low/mid 13s?
Your going to need 2 things.
1. Really good tires. IF he is half as good as you, he'll still beat you off the line, so you need to make sure it isn't by too much.
2. Some 3rd/4th gear pull. STi's don't have much pull once they are moving. Don't worry if he beats you off the line, because he will. Just make sure you have enough power to reel him in.
