This is a discussion on looking for real dyno numbers with Perrin vs. PW TMIC. within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; Originally Posted by Methodical4u pulled the trigger on the PW, GS 3port, and DW65c. I'll give you all some numbers ...

I'm going to debunk some things....
First, to the guy that said that the pw doesn't collapse under boost... IC hoses don't collapse. Inlet hoses do.
Second... A stock car or close to stock car will not see much if any increase in horsepower. You may see less pressure drop than stock, but pressure drop is higher at higher pressures, and a low pressure tune (at stock or stage 2 levels) you won't notice much difference.
Third: certain things will affect how your tuner tunes... ie boost controllers, solenoids, injectors, fuel pumps, etc. listen to your tuner on stuff like that. A tuner's preference on mid to high end intercoolers is purely going to be based on their opinion, not on how they're going to tune.
A processwest TMIC netted me 430WHP on a superflow (like dyno dynamics numbers). That's high 400's on a dynojet. If you have any questions about how well a PW TMIC holds up to 25psi and a high flowing turbo... I can promise that mine did wonderfully. When you start mixing and matching parts though, understand that nothing fits like it's supposed to. I had to modify my turbo coolant lines, my intercooler mounting bracket, and the intercooler splitter to make it all work. So fitment isn't a guarantee. Even with a high end intercooler.
