those threads are exactly why i ditched 2v anything.
my car was bone stock when i bought it. i lost to a couple of 4 cyl cars, and i added an SLP "X" pipe and high pressure regulator...
i lost to a couple of v6's, and i added a PI intake and port matched, as close as possible, my npi heads to a PI intake.
i still barely beat V6 HO pontiacs, so swapped to ported PI heads, stepped longtubes, stock PI cams, filter, and i lost to a 4v N/A cobra, and enough was enough.
i spent a load of money to get this in here and experiment with intake, exhaust, sensor combos, but it's worth the torque and HP. this swap can be done in a stang much cheaper than i did it.
forget 2v, and spend you money putting a 3v or 4v into your car.
filter, 'x'pipe, pullies. ~408fwtq SAE ain't bad for no real mods.
no arrogance. i can't wait to install those stepped torque headers i used on the 4.6. they have 2 torque peaks at 3200 and 4200 rpm with no HP loss, and the tapered runner intake i'm working on with 85mm TB. add 270 cfm/208cfm foxlake heads, stage 4 CC's and i will quit.
here is the end cap installed
