Conservatively speaking the car should easily see the 400whp mark with potential to go well over the 450+whp with this turbo on race fuel and appropriate tuning. Either way in a 2600lb car this should be pretty impressive

your front tires are going to HATE you

your front tires are going to HATE you

Hahaha you are correct I'm running lightweight 17's on the car now and the front tires will be the Nitto NT01's. The car isn't being built for the track it's a highway warrior

what are you doing for a tranny? I'm sure the stock one wont like this huge increase in powa

[crazybrew609]

stock tranny would take this power fine.. since he's doing highway runs with it.. but he's prolly got some slight modifications to some gears

[607Motorsports]

I blew out my stock tranny last summer when the car was supercharged. It now has an NVG T550 transmission with Torsen LSD in it. The tranny was only put in the Achieva SCX autocross cars and is supposably good to over 500whp... although there are no definative numbers so I guess we will see

I'm also running an ACT 4 puck solid hub racing clutch. Surprisingly this clutch although aggressive and has some chatter I find it to fairly decent for the street. The axles are my main concern as they are stock and have been known to fail in higher hp cars... There are some aftermarket ones out there i'll be looking into next season

That's awesome!

Im sure that your tranny will be able to handle it. Theres a guy on another forum Im on that has a twincharged cutlass using the stock 282 tranny. Prolly same one as yours using just different gear ratios. Awesome work though! cant wait to see that thing!

Don't need specs.

Dependent on your BSFC, 450whp represents the upper mark of your fuel system's capacity using 720cc squirters.

That's assuming you upgraded the pump and have balanced flow to all injectors on what i'm going to assume is an upgraded rail with negligable pressure drop between injectors. Without that, cracking 400whp safely won't happen.
