i doubt those will push u into 400 rwp. u need to add a cam with upgraded valve train, full exhaust, proper intake setup, tune and u should be there. dont forget about suspension and tires. power is nothing if u cant put it to the ground properly. lol thats what the shelby gt500s problem is.

I have yet to see a bolt on car make 400whp, despite the countless threads of people saying they want to try

-ssra/ftra
-lid
-smooth bellows
-160 thermo (does nothing IMO, but it's a bolt on)
-porter tb
-intake manifold
-spark plugs
-wires
-headers
-Y pipe
-catback
-electric water pump

that should be a start, but you won't hit 400 rwhp. if you just want to brag about a number to your friends, you can tell them it makes 400 at the crank, but I doubt you'll ever see that at the wheels with only boltons.

It'll take more than bolt ons to get 400 rwhp. If you just want 400 flywheel horsepower, then just he basic ones should do.

I got 343 rwhp on a Dynojet with the lid, ported TB, LS6 intake, QTP longtubes, custom catback, high flow cats, UD pulley, plugs, wires, and a tune on my 99Z M6. If the dyno is accurate and if (note the ifs) I'm losing 15% hp through the drivetrain, that's 403 hp at the crank.
