Being a newbie with turbos, can some give me some advice please?
I read this little paragraph on the regal website and it got me thinking
On turbo charged cars, that have not got a dump valve fitted already, the dump valve makes a big difference. Pressure is forced in the opposite direction into the turbo when the throttle is released, this causes a compressor stall and the turbo stops spinning when changing gear, resulting in a delay in initial pick up. It has also been known to shatter the compressor turbo wheel when running high boost. By fitting a dump valve after the intercooler outlet and as close to the throttle body as possible, excess compressed air in the intake system and intercooler is relieved when the throttle is released.
Can someone just confirm that the GSi already comes with a dump valve as standard please, as I dont want to find out the hard way when the turbo goes boom :shock:. If it does not have one, which one would be the best to go for and roughly how much will it cost fitted?
If there is one as standard, is it any good and will it be reliable enough?
Sorry for all the questions, but I just want to find all this out, as I want to be prepared
