Dead space in manifold after external intercooler
I was curious about what affect or better said the improvement we could get with the dead space where the original intercooler went in the intake manifold. I can only assume that all that open space might not be as efficient as just straight runners. Do you guys think the dead space has an affect on performance.

I've always wandered about this myself. Has anyone ever tried the '03 GTX SC intake on an RXT or RXP it didn't have the intercooler so it won't have this void.

Short runners no plenum = high RPM power
Long runners plenum = low end torque
tuned runners with plenum = bottom end, midrange, and top end
everything is relative, cam timing, head work, volume, intake velocity, exhaust velocity, etc... PR...
* there is a dif between wet manifolds and dry manifolds engineering, you still have to keep the flow/pulses moving...something like that...

Now were talking I thought about this once I removed my stock IC. All that open space cant be giving optimal flow.
