1400HP 65 Chevelle

Thanks Fesler.

I meant more on the side of drivability. I know Turbos you can have PSI turned down when cruising and it acts normal or you can boost the PSI up and HP turns on (all from inside the car). While a supercharger is on non stop as it is driven by the belt.

Wondered if anything has changed in relation to that or whether that is the problem to Supercharging. I Remember many years ago when I had my 72 Valiant Aussie Charger going to Pac Performance here in Sydney and asking them about 800HP or so. They told me if I supercharge the engine, it will be a pig on the road and totally inefficient. If I turbo it, then I can turn PSI down to have economy while cruising and if I want to give someone a run, I just turn the knob to increase PSI and HP comes on.

Many years have gone by since then so perhaps there was something new created I am unaware of that eliminates that problem.

Mayhem makes 877 hp supercharged on pump gas and I will be driving it on Power Tour. I also have the Mule twin turbo car and it made over 1000 hp but on 100 octane. The Supercharged car is very NOT a pig. It is making 877 hp at only 10 psi. Very easy going. I prefer the wide power band of the Supercharged car as opposed to the Boost hitting all at once on the turbo car.I also had a Procharged car making 800 at the wheels that I would never drive on Power Tour.
