Looking good! try http://www.xlr8.co.im/ for air horns. but its not just the longest length that will give you the torque. the inlet tract has to match your car also
Cheers vwj1m, checked them out already they might be able to help, tho my bodies arnt usual size and make, so i might have to source original mv agusta air box and utilise it Your setup looks well there is a good read about length of inlet tracts and size of plenum chamber in this months "Practical Performance car" mag Aparently most 4 cyl engines need very long inlet tracts Its all to do with positive and negative air pulses improving volumetric eficiency of engine..... For the inlet manifold they were making ideal length of inlet was 30"-s long! That wasnt for itb-s tho but a normal efi with single throttle bodie Worth a read tho
Im fairly sure 3bar is enough fuel pressure for you... My car uses a fixed rate FPR set at 3 bar & provides ample fuel for 200ish BHP with 268/276 cams & 7600rpm I know thwe injectors are running at close to their maximum duty cycle @ the top end, but the fuelling is bang on!! 15MPG would suggest the flow of Optimax is ample too
15 mpg Your right foot must be so heavy Anyone got diagram of how to wire in coil packs and crank sensors? I know there are different ones but surely they will be simmilar
just follow the pin numbers on the ecu,each pin number relates to where it connects on the engine,there might be a loom in me mates yard if you need one
If you can get hold of a loom that would be grand Louis! I am just trying to bolt up pick up wheel, how did you center yours so its perfect as i belive crank sensor needs to be very close to it? I wan't be using power steering so the pully its off and i will bolt pick up wheel straight to the crank pully
Update to anyone who needs to use a coil pack for simmilar itb conversions, citroen and pug coil packs fit oem vw ignition leads which is very helpfull
I fitted a socket into the centre of the crank pulley(dont remember the size but was a perfect fit)then had the pick-up wheel centre taken out to the size of the socket on a lathe
