supercharger and turbo'd 200 :-)

How cool would that sound
be some nice clouds of black under load too ooh I love diesels running lots of boost

It can with bigger internals :wink:
Supercharging.... is ok but does sap power. And I don’t think it would work with a v belt, most require a serpentine belt.
Twin turbo, lots of effort and need to make sure you don't over speed the smaller turbo... sequential turbo's are nothing that new. But will require a custom manifold, and you’ve got the problem of packaging.
Packaging wise, a VNT makes more sense. :wink:
Boost pressure… you’ll find the rings and pistons will be the next weak point. A wired block (as already mentioned) will make head gaskets last a bit longer.

If you try to run more than 17psi on a T25 it becomes very inefficient, a hybrid is slightly different, but not much.

1 big 1 small turbo :wink:
just the small 1 running at low rpm, and quite litraly at 800rpm itll be spinning up
look under the bonnet of a new ford fiesta, 1 small turbo...spins litrally AS your pulling off...dan

ah, compounded turbos, sort of scanias 14L470 motor. real nice for pulling heavy loads. now i see...... thinking
Devon-Rover:
Is it I belive that a stadard TDI turbo can go to about 20 PSI then it actually restricts it self as it can't spin any faster. Also thinking about it what happens when you shut the throttle off OK a Diesel as a wide ope throttle (i.e. no butterfly) but surely the boost must go somewhere and so would it take a little longer for the engine to throttle back? Else would you have to think about a dump valve to help rid the system of the pressure?

disconected the wastegate on my tdi to race a saxo & it pumped out 24psi o boost, smoked the shaxo & went of the lights spinning the wheels :lol: :lol:
1/4 mile here we come 8)
