Who posted the technical thread about Back pressure on turbo

[Pummy]

Good point KAS. I did not think of that as an option. In any case I will still try and get one which is about 2.5 / 3" in diameter because I want it to still be recessed into the bumper a little like my old car was. I do not like the thought if it being a low rider with a tin can sticking out the back.

2.5" is more than enough mate

I think i only got 2.25" coz i got it straight thru 8)

remeber that most of the back pressure that a turbo engien see is fromt he actual turbo

[manicajk]

exactly so the greater the pressure differential from before the turbo to after the turbo the quicker you will get your turbo to spin up

[KAS]

but too much and you will get exhaust goin back into the engine innit
