I'll try to keep this short and sweet. Keep in mind this is a 6spd car and the kit is on a progressive controller so traction issues won't be "quite" as bad.

No power steering, ac, or smog. elec. water pump and some minor weight reduction. Race weight is ~3400 probably less, haven't checked recently.

Suspension is 90/10s, moroso front springs, LCAs and re-location brackets, air bag, 26x11.5x16 et streets.

I've seen similar cars do very well w/ this setup and others that made embarrassing power. I was hoping for a high 11.XX on motor. Is that asking too much?

If you want to know what it will run, take it to a track. Not every car responds to the same mods. What works well in one person's car may not work for yours. The only way to know what it will run is to actually take it down the track.

If you want a guess, 11.00 - 13.00

600+ hp won't run 12's if the power can't get to the ground.

if you can get the power to the ground on the motor mid to low 12's would be my guess. On the juice and saying you can hook maybe mid to low 11's. But i hope that your internals are built to handel that much juice cause other wise there will be a lot of metal hitting the pavement soon.

They are. They only thing keeping me from spraying more is my ring gap at this point. So you're saying an extra 300hp is only good for 1 sec.? I've seen others run high 11's on motor and spray a 150 and hit 10.90's.

That is a lot of nitrous. I will say that I had a friend who was making 527 horsepower on the motor with a solid roller "nitrous cammed" 350. On the dyno, the motor "stalled" out after a 200 shot. There was no difference on the dyno between a 200 and 250 shot. He had a setup similar to yours in terms of compression, displacement and cylinder head flow.

And I would imagine you will land in the low to mid 12's N/A and well into the 10's on the motor. I think how well you can drive at the track is going to play the biggest factor.

if that combo does not run at least a 11.2 on the motor, then your doing something wrong. its amazing how many people build engines with an awsome potential and they end up running mid 12's. i think more people should concentrate on putting power to the ground to better there et's instead of trying to make more power. if i can run 12.45 with 275whp, you can run a 11.2 with this motor witch should make at least 360whp. i wish you good luck, and never settle for a 60' time of 1.8 and higher!!!

I dont see that setup running anywhere near 11.2 on the motor. That is not a great n/a camshaft- too much exhaust duration on a cylinder head with a relatively good i/e ratio as well as too wide on the LSA. Plus its a gearbox car :shrug:.
