Got it. That makes sense. And that would be fine, since the capability of the Roush R2300TVS intake manifold is such that it can support a blower as large as the R2300TVS blower. By putting the GT500 blower on it, you are running a smaller blower - so you have adequate intercooling for the boost you are running. If you went the other way - and tried to put a GT500 blower on a 4.6L Roush 445 intake manifold, you would be in trouble, since the intercooler is too small - unless you turned the boost way down. The bottom line is that superchargers are designed to work with an intake manifold that has a given cooling capacity. It is OK to have more cooling than needed, but not OK to not have enough. Since your details were sparse in the initial post it was hard to tell if you had a good idea or a science project gone awry. Anxiously awaiting pictures.
This reminds me of the lightning engine put into the 1995? mustang. Nobody believed it, but it happened. I cant wait for the pictures
Like I said, plans changed, the GT500 Eaton M122 isn't going on the car right now. I've got something else on it currently. I'll post a thread later tonight. I need to go get some sub par photos.
