sup fella's, my setup right now makes me 415/380 with stock ls1 intake, TB, and pulley...im shooting for 400rwtq and wanted to know how close i'd get with the addition of a ls6 intake, ported TB, and pulley? my goal for the car is 430/400 anything above that would just be a bonus...so how much power am i looking at gaining with the addition of these mods? im thinking ill be looking at around 430/396 or so, which would be ok, im just wanting to see that 400 for torque you know...

mods:
Lid
TEA 5.3 st. 1.5
F14 112+2
QTP LT's 1 3/4, mufflex ory, gmmg

thats pretty much it for mods...besides the freebies..

just wanting some opinions, guess's...thanks..

Jon

 

I think you know what you need to do. With that cam, heads, and exhaust, your car needs to breathe. Pick up an intake, ported tb, and that pully, and I see no reason why you wouldnt get damn near if not over 400 tq

 

You will probably get around 15-20rwhp out of the intake swap alone.. Maybe a few more than that.. I'd say the ported throttle body would give you 5-10rwhp and about the same for the pulley..

I'd say at least a 25rwhp gain from those mods would be about right.. You probably wont pick up a whole lot of torque from the pulley or t/b, but the intake swap should do 10+ft lbs..

 

I am running a 232/242 on a 111lsa, and i am currently making 430/400 w/o a pulley. I think with the additions you are making, you should be all over your target number

 

thanks for the reply's guys..i been reading alot of threads, and searched many times, and figured i'd be right around my goal...i just wanted some feedback from some guys with my setup, or something close to it...thanks again...well, looks like just a few more mods and ill be done with the car for awhile...then again, that D-1SC looks like alot of fun...
