Hey guys i just bought myself a au series 3 xr8 (220kw) and just wanted to find out how to get some cheap HP from some bolt on mods any suggestions??, already getting a new exhaust, extractors and pipes. :driver:

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....

Thanks for the info, im waiting to get the exhaust done and servicing the motor as it has a little miss down low, what air pod did you use and how did you set it up?

you cant use the tapered pods as they hit on the air box. you need a straight cylinder type, and fit via a 3" tube into the alloy trumpet in the inlet. but if its too hard to find one just go a flat panel k+n. if you have over 60k kilometers then you should look at replacing the platnum plugs and or the leads(for the miss). dont get genuine ford leads at $940 a set. go for top gun at $100.. cheers

ye gr8 advice top gun leads!!!!! u gotta b joking, i prolly wouldnt go genuine at $940 either however i would go a decent quality lead like a bosch or ngk. does any1 make and electric water pump 4 those motors? i know on a holden u can get sum gr8 gains in kw.

go for a crane 2031 cam if u have 1.72 roller rockers i reakon. and wat the rest said, CAI etc.
maybe even diff gears to get off the line quicker - 3.7/3.9's.

If your after some decent power gains get a pair of AFR heads (preferable 185's) and a decent cam

Trickflows work better than a AFR's on the 5.0's. More torque/power in the midrange.

We generally use a Comp Cams 35-351-8 hyd roller in the EFI Windsors we build, with Trickflow heads, late model intake setup and an upgraded fuel pump you'll make approx 286rwhp from a 5.0 and 310-320 from a 347 stroker.

just built one, with the same cam and same 185cc trickflow heads for my 347, in a AU 2 with 5 speed. should get aprox 320rwhp but with 80% of my torque from 2000rpm. long live the 347..

yep great little combo, its what Ford should have released the XR8s with.
