the bc4

[bc4 boy]

k i juss bought a bc4 and i was goin to race a 1996 trans am with headers it is a 6speed my car is a 6speed but i realy dont no what kind of power my car is pushin do u think i could win aginst him and what do u think my first performace upgrade should be.

cold air intake

What year is it? I have a 97 b4c. I have a rear mail seal leak, I'll get it fixed when it becomes a problem because I don't have the money right now. When I dyno'ed it a few years ago i was getting 220 rwhp and around 240ft/tq if I recall correctly.

1996 Trans Am with headers will be making a little over 300 hp, about what your LS1 makes (sorry, its just a myth that the B4C cop cars got beefed up engines/computer controls).

Its a drivers race IMO.

[bc4 boy]

well that suck i was hopin it would be faster than most ya no damn. but that tran am is a lt1 not ls1. so wouldnt it come down to who ever got the wholeshot or who could drive better and my 1994 bc4 has a cold air intake with short throw shifter if that help any.

[cuda_dude]

what kind of CAI? your next mod could be an exhaust or little mods that add up like a trick flow intake elbow, air foil etc.... if you've got the money and are good with cars it's easier to do the headers at the same time as the exhaust

[bc4 boy]

k i do have another question tho other than the one above this lol. does and msd ignition system like wires and a blaster coil and good spark plugs with one of those rev limiter box things. does all that realy help much in a race.

[bc4 boy]

and it is a slp cold air induction system

[cuda_dude]

no, not enought to be noticeable... i think you would gain more in mpg than hp... you might gain a few but not a ton

[97copcar]

From what I have seen, the b4c package had the sport suspension, factory tranny and oil line coolers, 4 wheel disc and the speed limiter removed.

A 96 TA with headers won't be making anywhere close to 300 hp. Even with a tune. Sure, LT's help, but not that much.

I just find it funny he's forever tagged himself as "bc4 boy"

Almost as bad as Cameroguy

Sorry, just find that amusing.

300 would be hp at the crank not the rear wheels

[ikeyballz]

huh. so not to thread jack or anything.. how much rwhp do LT1's have? 200 (as 97copcar said?) thtas kinda sad my friends S2K has more rwhp. although, i know it dpoesnt matter in a race since his car has no low end grunt..

[cuda_dude]

an estimate for an m6 would be the 275 minus 15% for drivetrain loss i think autos are closer to 20%... but then again you also have to figure a lot of the LT1's had underrated hp #s from the factory (didn't want to upstage the corvette)
