Turbo chadder / knock?
Is it possible for a turbo to have asevere loud chadder that the owner said was a wastegate that was opening and closing at @ 1 to 2 times every second while under full throttle? The engine and boost had no problem with smooth power delivery, it was just the noise.This car has been sitting for weeks, if not months. This was not a mitsubishi motor but I am just wondering if anyone has came across a problem like this before?

It was a metal hitting metal sound. The turbo whine was quite loud with no changing of the pitch, the hitting sound was a really quick tap against metal that was just a bit louder than the turbo whine. The power increase was very linear with no jumps or peaks andno release of air noises.

It's a 86 Grand National with the 3.8L turbo/ intercooler motor. It hashad a couple of things done to it. ( injectors, empty cat, exhaust, K&N, shift kit and a manual boost control )
I was thinking that some of the guys on this forum has had more experience with turbos than the average car buff and was thinking that the (?) manual boost control might be the problem.It was like someone was under the hood hitting 2 frying pans with a large spoon, while this was going on, it was pulling like mad.
Thanks for you inputs
