what is max cfm and rpm for one of those? ( I think they have a veriable speed trany in them?) or do they have different models with
diff. out puts...etc.?

on the units you have on this set up how do they compare to the C-2
procharger head unit? (if i'm in the ballpark)

We used two 81 units Which are the biggest units.We didn't push the envelope with these I would say there getting close to max at around 900 to 1000 hp on this set up .But the belt is really working hard at that level.

Tom this is going to be serious competitor for cammed crate LS7

How long have you been working with rotrex blowers,what do you think of those ?

[TOM NELSON]

This is the only graph i could find to post.Running very rich on this pull but you can see the power curve and get an idea how it comes on boost and make it's power.Just keep in mind this is with a bone stock cam and 8.5 compression.

This is the first rotex weve done.Everything has it's place .I think as a super driver with good power this combo is killer.If your looking for big power this is not the way.But i think for most this will be enough.on the next one we do i will make a 12 rib set up on the belt and be sending a 12 rib to this customer.I could see the belt wearing pretty fast.It lasted all the dynoing but i think a 12 rib would cure the deal up to around 15 psi.The real draw with this motor is how tame and docile it is It will be like driving a new car but with a **** load of power.But click it in overdrive and turn the radio on and enjoy.Smoke a viper if he happens to come your way in the mean time.Thats the beauty of forced induction the turbo motors are same way they will do the same thing but probally twice the power output but they also cost about 10k more .Just another way to skin a cat.

Very nice! You do good work. Have you ever messed around with E85?

81 units? The biggest that they list on their website is the c-38.
