Title: G40 manifold or Gt, whats the diffrences?
Post by: LeonBritton123 on January 25, 2009, 06:08:18 PM
Whats the benefits from using a gt manifold on a g40?

My setup is

1341cc bottom end with wossner forged pistons and standard compression ratio
Lightened and balanced flywheel
Paddle Clutch
Standard head and standard cam
51mm Throttle Body
Green Injectors
Chip to suit
Full Blend charger with 65mm pulley and standalone oil supply.
Air filter and jetex exhaust.

Do you think i would benefit from a gt inlet manifold?

Yeah defo, have a look at a G40 and a GT manifold side by side and the difference is obvious. The GT one is so much bigger! Coupled with the 51mm throttle body you'll notice a big difference.

I remember Pete pulling away from me on a motorway with ease once and wondering what was going off and he'd fitted his 51mm throttle and GT inlet and failed to mention it. Made a huge difference on his car.

its not running yet, had a slight problem with the last head and bent valves, but all is good now as it turns over by hand really smoothly and builds up compression so its looking good. Ill have it on the rollers once ive run it in and probably do the strip at santa pod a few times this year.
