Vette numbers coming shortly! Will it make it?

 

451 rwhp/393 torque through stock exhaust manifolds, cats, full emissions and no tune...

I will have the new results up today with the new toys

 

480 / 412 and still tuning

 

So what's the verdict?!? Did she get there?

 

Questions: The 112 rating on the Eaton blower... is that the same rating as on some 'regular' roots superchargers? (amount of air displaced with one revolution)

I've read about the 144 mini-blower (B&M?), putting out over 650hp on a 350-355 Chevy. That may have been engine dyno, but still... (I'm trying to find the article)

What would be the big bottleneck with the Eaton? The twisted rotors? The displacement? The small intercooler outlet under the rotors? Manifold design? Lack of efficiency?

 

650 to the flywheel is about 500 to the tires maybe a little moe on soem vehicles. Was that a motor the would have made 550 on its own though.

 

I don't think there is a big bottleneck with the Radix, however there is a design limit. So far, speculation rules the day. Efficiency is very good, better than most will admit. Again the 40-50% rating is on the original GM roots blowers (twin rotors with no twist); the radix is a much different animal in the same species. Anyway, 112 cu inches per revolution.

 

nah, on 91 octane and stock pulley 480 was all we could get without going aggressive on the tune and risking him blowing it up... had it been my car I would have gone all out

 

Thats still pretty sweet 480 is haulin some major *****. Im impressed!!!!!!!!

 

was that 480 rwhp the vette or the truck?
