Does anybody know what a safe boost pressure is on the 2010 speed 3's? im running 18lbs now. how much can i go up? i have full race exaust 3" turbo back, K&N cold air, cobb tunning turbo inlet pipe, SU dual blow off.

 

Hello????

 

not one person in the whole forum has this answer?

 

had a friend of mine go to tuner car school. one of the project cars was an 08 speed. he ran 25 lbs for two years then bent and broke all kinda s..... . so i would think 20-22 max on stock internals. just my op.
