Re: Bolt on power gains for 5.0l
1.72 roller rockers,uni-chip or std computer mod, hi-flow pod filter in the air box with a 70mm hole in the bottom, 10mm heat spacer in between the upper and lower manifold, hollow cats. dont worry about a throttle body as the 220 motor already has a good one. see if you can get the pacemaker tunned extractors as these were the best that i tried. also helps to debur the in side top of the air box to stop turbulance.. with these mods to my 2000 au ii 200kw motor, i got 238rwhp. std was 198..cheers....
