Gents,
On my way back from Le Mans (See coole rides topic ), I noticed that the turbo did not come in at 2800 rpm, so loss of approx 100 BHP...
The strange thing is, that the turbo does work when the engine is off for a while (Fuelstop) back on road and it worked for a litttle while.
I think it is a waste gate issue (exhaust valve not closing, spring broken, or membrame).
Wastegate because in my vieuw turbo is not building up pressure...
Any ideas???
Many thanks

Wastegate could be stuck open then exhaust does not go troug the turbo so much.
Pop-off valve could be stuck open, then you also loose loads of power.

Read your PM lately?
