No a/c, pass. airbag, stereo, speakers, rear seat, washer fluid reservoir. Car also has koni's, strano springs, lca relocation brackets and bmr rear suspension peices and torque arm. Umi torque arm relocation crossmember. What do you think it will make n/a and on the 150 shot? Any 1/4 or 1/8 mile ideas?

I was told around 450 rwhp and 450 rwtq. I know I wanted to go 10's on motor. What do you guys think?

That is one NASTY combo !!! I'll guess 475/455 SAE and depending on weight
and driver mod should go easy tens NA. Happy gas should get pretty stupid
in a hurry.

Thank you.

Anyone else?

Idk I hope 475+ because Im planning on doing a very similar setup, except with a t56.
Any updates on this?

Just waiting on the converter to come back from being restalled. Then it will be finished up. I was hoping to have it back at the end of the month but that isnt going to happen. I don't even know if I will get it dyno tuned simply due to not having alot of free time.

Believe me, I want this thing done bad.

Yeah I'll be waiting to see what it makes. I'm going to do almost everything the same as you are, except I have a MS3 cam. So a little smaller cam and t56 should make good power, and MS3 likes nitrous so hopefully really good nitrous numbers.

That's the one thing with my setup. I wanted to make great n/a power and then spray it for alittle extra. Alittle more split on my cam and it would have been a monster on the bottle.

Yeah thats pretty much what I'm doing, because I am not going to spray it that often.
