Installed a BOV on the car. Car ran fine for awhile, until we were driving, and he hit the accelerator to achieve boost. As he was boosting, we heard a loud bang from under the hood.

The motor runs fine, and the turbo's do spool up, they are very loud. We just dont get boost, at all.

Could this be a vacuum problem? What could of made that noise?

Any suggestions would be great.

Current mods:

HKS dual intake
Apexi N1 full exhaust, catless.
Greddy bov

 

my buddies car had the same problem but on a gtr....when his bov was connected to to vac line it seem to not get ny boost at all..while everything ran normal.....we removed the vac line from his bov and jut caped it of and it seems to run fine....not sure why but u could try that....tuning issue maybe
