Has anybody had direct experience where the turbo radiates heat off onto the radiator?
I have a GT4 which is a transverse 2.0l turbo 4, with the turbo mounted directly behind the radiator. There's about a 40mm gap between the dump pipe and the radiator.
The engine has just been rebuilt, and now the engine temps seem to go through the roof whenever boost (ie the turbo starts to work) builds.
I'll admit that we are missing one standard heat shield which (if you know GT4's) goes over the manifold and half covers the turbo, but can that make a difference?
The dump pipe is wrapped in heatwrap.
My thinking is I'll have to increase the shielding and doing a search showed people using the ACL XR6T stuff (which I'll have to try and find). Obviously, sandwiched steel with an air gap would also work well.
