Title: audi tt petrol turbo on a diesel
Post by: GTIcheeseman on 25 August 2012, 14:11
Right my mate has got a pd 150 and he has put an audi tt petrol turbo on it, now when I was studying I always got told you should not do that as petrols run to much higher psi than diesels ,
Is that right

i always thought a diesel runs more compression than a petrol

Yeah engine wise they do but I always thought you shouldn't put a petty turbo on a diesel. I know diesel engines run a lot higher engine compression

diesels boost way higher than petrols, particularly in standard form. I really can't see how your mate has managed to achieve this.. it just wouldn't work for so many reasons. Unless he's used a turbo from a new shape diesel TT? but even that wouldn't be straight forward!

Diesels are on boost much more under general driving conditions  :shocked:

Diesel one works on a vacuum...I assume the petrol one is the other way around.

2 things here that gets me, first off is the 150 turbo is part of the manifold and the TT one isnt, so to fit a TT turbo would need a new manifold made, so in my fag packet maths he would have saved money to have a 150 turbo hybrid, tbh i dont belive he has fitted a TT, just trying to play billy big bolloxs, smile and wave boy, smile and wave
