My other turbo'd car has an IC that stays cool and boost pipes that stay pretty cool. Last couple of days I start using the zed again because its sunny dry and cold. It goes brill and the boost is high. Yet even after pottering when I stop it and check the engine the boost pipes are always warm, the plenums are hot and the metal parts even at the sides of the rad are hot. I wondered if my ICs are partly blocked off with dead bugs etc and not cooling like it should. Any ideas?

More likely that the pipes are picking up heat from the rest of the engine bay - oh yeah and also the stock ICs are crap ;) Zeds do run warm in the engine bay - hows the temp guage running?

Temp is perfect. The engine purrs. I just felt that the pipes each side of the rad at least would be cool to touch but its always been this way. Looking in the vents at the front the ICs have a lot of fins dinged over from splatting bees etc. Maybe I should take the nose off in the spring and straighten them out. Its just that it really pulls like a train in the cold weather and the boost gauge goes higher than usual. I might even have heard pinking the other day - first time ever in 3 years plus. Maybe because I left it off the road the last couple of months the combustion chambers are a bit furred up.

After a hard run, my boost pipes feel hot too, as does the whole engine bay. Temp gauge still normal, though.

 

I also had the same with my old Supra, when I parked up in the garage, you could feel the heat radiating from the whole engine compartment.....
