Thanks

Are you referring to back pressure in the exhaust system or the intake system?

HI

Thanks for the reply. I am reffering to back pressure between the exhaust valve and the turbo.

Or pressure between the exhaust manifolds and the turbo. ie pressure before exhaust gas enters the turbo.

I have hear that if you have a intake boost pressure of 10 psi, your pre turbo exhaust pressure should be not more than 20. Correct?


Thanks
