Hopefully my build will be done in the next week and I’ll be out driving soon.

After coming from being supercharged for 4 years and now having Fast Intentions tt's, I'd never go back to superchargers although the Rotrex is a good alternative and a hell of a lot cheaper

Cool yeah turbos can be a ton of fun. What did you most like about switching from superchargers to turbos?

The biggest thing is the turbos make more power at a lot less boost than the supercharger did. A couple other things are belt slip issues and I was getting real bad bov flutter. Keep in mind, I was pushing the crap out of a Vortech though. I'd never do another build with a Vortech. You're on the right track with the Rotrex. Here's a dyno comparison chart of my Vortech compared to the TT's. The TT's are the red graph

Bruh, the supercharger made more power so clearly you’re wrong. I kid, I kid. I’ll bet your car is a hoot to drive!

I like it because it has the linear power curve like the supercharger but makes more power and torque in the lower rpm range. Just for fun, Seb added a few percentage points to the duty cycle after that run and here's what it did. He backed it off to 15 psi so it's making a little over 700 on my high boost map. It's a blast to drive

That looks pretty sweet! Eugene's got me set up at 13lbs of boost. I should be doing a dyno day in about 6 weeks and I'm looking forward to seeing what my car looks like too.

Post up the numbers. Always love seeing what the Rotrex is capable of
