Hi,

I have a FD running with single turbo making about 9psi. When i drive slow without make boost... there is any problem. When i make boost don't smoke nothing... but... after i remove the foot from accelerator and make vaccum on intake it smokes like crazy.

I can drive from 0 to more then 100mph and it don't smoke if i drive in full power...

Anyone with the same problem?

Suggestions?

 

Does it only happen during decel after full throttle?
Might be inadaquate oilpan ventilation.

Get an oil catch can and vent it to atmosphere or plumb it back into the intake tract before the turbo.

 

Yes... only happen during decel after boost!

But tomorrow i will test it

 

Not to suggest you do it often but what does the smoke smell like ?

I had my secondary injector ( from RC engineering 1300cc )stuck open and I was kicking out a ton of white smoke. It wasnt hard to smell the fuel. Just a thought

 

Hi,

The problem are solved. Is the inadaquate oilpan ventilation.

Thanks a lot

 

MY TWINS BLEW WHEN WHITE SMOKE CAME OUT. but the smoke doesnt start until either the cars been running for a while or you build boost!
