Looking for guys with first hand knowledge running very low boost pressures (4-6 psi) on vortech/paxton blowers, without any form of intercooler or aftercooler. What kind of IAT delta's are we looking at vs. ambient air temp? What temperature delta's are common for let's say a vortech after cooled setup @10 psi? Similarly, how about the guys that went from a non aftercooled low boost setup and added a form of charge air cooling afterwards; what was the difference in IAT's?

Thanks in advance.

 

Your going to see 150F+ on the street nevermind any possible tracking, an after cooler 110-120f with and that's at high boost. A huge difference. It means engine longevity vs limited. And much more consistent power delivery. I would never run an old comptech kit without an after cooler. They learned a lot since those early days. Many have detonated and killed thier motors to prove it.
