Aftermarket turbo exhaust manifold?
Are you going to purge the waste gate in the engine bay or have it plumbed out of it?(Since it's on the exaust side) I've only seen them on boost side not the exaust is why i ask?
To answer your queston, first, yes, we'll run a pipe down beside the engine for the waste gate exhaust.
One thing.... Waste gates are ALWAYS on the exhaust side. The plumbing on these things can get a little complicated.
I think what you're referrring to, is a blow-off valve, OR a boost controller that works on the intake side. Both of them are plumbed into the intake system, on its way to the carb or injector throttle body.
There are boost controllers that have a butterfly in the intake system, that closes, or partially closes when the maximum set boost level is approached. The old ACCEL units used these, but I haven't seen one since. Nobody seemed to think that they worked particularlly well.
Additionally, "blowoff valves" are on a lot of setups to protect the turbo (or centrufugal supercharger) from the buildup of boost that occurs when the turbine is spinning really fast, and the throttle snaps closed,as in a burnout. It opens and lets the built-up boost escape to the atmosphere. I have heard of that "boost air" with nowhere to go, being routed to the intake side of the compressor, too.
But, wastegates are
always a function of the exhaust system, as far as I know. They are boost-controllers, and open to deprive the turbine of excessive exhaust flow that could over-boost the engine.
Hope this helps (
and, I hope it's RIGHT.) This is the first "turbo" car I have ever built.
