intercooler size limits
You can do ten runs back to back on the freeway and you're still not going to come close to simulating all the radiated heat and heat soaking that you would see on the track.
-turbo glowing for 15 minutes = engine bay air temps astronomically hotter than under usual street or dyno conditions. Even with heat shields and ducting this is unavoidable. It's like doing dyno pulls in the middle of Death Valley. Over and over and over again.
-Yes, your compressor housing will be stupid hot
-Yes, your intercooler will get heat soaked
I would not feel comfortable with a smaller intercooler on the track. Look at Savington - he's at your power level. He's not using a tiny IC . You can only get away with stuff like that on the street.

And people keep asking my why I bought a Rotrex.

:P... I love turbo cars but after building RX7's for a while and then the turbo NA last year I wanted to try something new. So far the heat in my engine bay is almost non existant and with the addition of the TDR heat sheild I just bought today it should help even more.
I am running a 28x7x2.5 IC. It's just at the limit of what I'm making right now (225whp) so when I up the boost and get a manifold I am going to have to get something bigger. Although after some hoolaganism yesterday in some back roads (yes I know not the same) out of curiosity I popped the hood to feel the cold side charge piping VS the hotside and it is a big difference so the small ic is defianatley doing something..
