Problem with boost...
Ok heres the deal,
I have a custome front mount and a s4 turbo on my car with 3 inch exhaust. My problem is that the boost slowly gets to 10(kinda slowly but fast enough) then just takes off. It a streetported motor with little things here and there(I got hte turbo manifold holes drilled a little bigger.if that makes any sense) Why is it doing this |

ok wait, Are you saying that boost builds to 10 then just screams higher?
|
Might be time to port the wastegate. I am having the same problems. Or you might need to check the wastegate for proper operation.

wastegate

SaabGuy: wastegate
Bingo |
yep, time to port that bad boy
|
it's not hard but it will require taking off the turbo, taking off the end plate where the downpipe bolts on, and taking a dremel and making the hole bigger.
|
cool, I'll do it tom.
|
Thanks for the help everyone.
One more question, is there such a thing as porting the wastegate to much??? |
yeah you can port it so much that the flapper dilly is smaller then the port itself....
