Factoring in temp, baro, dew point, altitude. Calgary is equivalent to 6300 ft today. Higher than Denver on a standard day.!

If you put this pre-twin screw, does it become a restriction or does it "help" the twin screw at WOT?

Compounded with Eaton.

I'm thinking there should be two versions for sale.
1) The all out version that needs a tune and makes max power.
2) A version that limits boost to whatever the ecu can compensate for for those who just want a nice little bump and don't want to deal with tunes.

I am guessing that is a roots blower that doesn't compress the air in the housing. I wonder if that matters.

And judging by those boost curves, it looks like with the big electrocharger the eaton produces 8-9 psi right off the bat and holds it to redline. The eaton by itself only produces 4 psi initially and then ramping up to 8 psi by redline.

So the two charging systems work additively.

Yes, also note his recorded 3rd gear pulls from 2000-6200.

The Eaton covered that distance in 11.3 seconds.
Compounded with the big e-blower...9.5 seconds.

Yep it is clear that on that setup, the two systems are working nicely.

I look forward to seeing if you guys can get this motor to accept boost in the 2-3k rpms range on pump fuel without throwing a fit.

3K should be no problem, 2K< either stay away or a TPS/rpm window switch will work. There are several of these devices available, no point in re-inventing the wheel.

VERY interesting. Any data on running this on a completely stock engine/intake/exhaust?

Fentons car is stock. Right down to the tune currently.

Thanks. Did I miss that somewhere? I'll go back to the start of the the thread.
ETA: Duh, first page. I thought Fenton was somebody else, sorry.

Anyone running this with something like a Shorai battery?
