Then again we did make 501 whp (mustang dyno) just by throwing a rotrex on our stock engine car *No tuning changes*. This is exactly the same whp that our low compression car made on our dyno.
Difference: 20 whp more than our hks unit at the same psi and more tq as well.
I'll have som data on how they stack up with a little less boost later on.
Hopefully someone can post a Rotrex making the 600 whp Evolve claims on a dynojet. Drew made 600 whp at close to the same boost you had Andrew on your beta low CR motor, he also has a beta low CR motor so thats about as close a comparison as it gets.
BTW Andrew why did you guys stop using Rotrex in your kits and switch to HKS? Did you find that the HKS performed better at lower boost?
