100-125 MORE horsepower in a 1900 pound car? Damn that sounds terrifying!
You are such a bad influence, I suppuse I need a 930 transaxle too while I am at it?
Well crap, now I am going to have to sink even more money in to this fricken car!
I thought a Murcie was out of reach but now, well, can you imagine a 914 beating a Murcielago in a race? I think I would die laughing!
What have I done...
Yup.... My 2006 WRX (stock) is 230hp, after 25% in drivetrain loss, you're only looking at about 175 hp to the wheels.
Bellmouth downpipe, 3-inch exhaust, and a cobb accessport... I was at 285 hp (stage 2)... I think that ends up to be around 230 at the wheels.
Bolted on a VF39 turbo (it was a straightforward install), downloaded a free map online from Cobb..... boom, 362 hp.... just like that.... free, no dynotuning required.
I got ancy... and forked over $400 for some fine-dynotuning at Cobb in SLC.... they got me up to 304 at the wheels by maxing out my injectors.... 380-ish at the crank. All I've done since then was add an intake... so I'm guestimating right at 385 crank hp.
Keep in mind.... I'm turning 5 driveshafts and heavier wheels.... you're not.
My local club/website (SLCSUBARU.COM) has several guys running WELL over 350 WHP (close to 450 crank hp) on the stock internals. I've seen STI guys run close to 600hp on the stock internals..... It's all about the size turbo, the fuel system to support it, and the tuning.
I would say your biggest issue is going to be tranny strength..... and traction
