#27305, "The higher the RPM the less the boost...(need help)"
Try this turbo guys: Go about 1/2 throttle, or at a position where you can build a little boost, from say 2k and keep it there till about 6k. Now tell me this: Does your boost stay constant throughout the band at a constant throttle postion??? When I do this my boost drops off steadily as my rpms increase. Even when I try to do about 1-2lbs it'll eventually end up in the vaccumm!! If it is a boost leak I can't f'in find it. What are common places that I should check

Alvin, i think this is normal cause when you reach higher rpm's your engine requires more air, the turbo is producing enough to build boost at the current rpm, but as the rpm goes up and you are not putting out as much exhaust energy to turn the turbine (due to less load) your engine's air needs exceed the airflow of the turbo thus producing vacuum. hope this helps lates james
