How much compression can you run with a blower?
You should be able to run a 7-8 psi blower with a 9:1 static compression ratio and the engine might run fine on 91 octane fuel. Changing pistons is the best way to affect this change, but it might be possible to reduce compression ratio by switching heads and adding a larger combustion chamber.
What compression do I need to run a supercharger?
The optimum compression ratio is 8.0:1. Higher than 8.0:1 is not necessary or recommended. Fuel, ignition timing, and total boost could become critical factors.
How much power can a 6-71 blower make?
Driven 11 percent under, the 6-71 produced a boost curve that began at 4.2 psi at 3,300 rpm and rose to 8.3 psi at 6,400 rpm. This pulley combination produced peak power numbers of 602 hp at 6,400 rpm and 551 lb-ft of torque at 4,700 rpm.
Do superchargers make boost at idle?
Inactive. The supercharger will not make boost at partial throttle because it is sucking air through the thorttle body. The bypass valve is just to improve efficiency at partial throttle. It does not control boost (unless it is broken).
How much horsepower can a supercharger add?
50-100 horsepower
Supercharger or turbocharger A turbocharger works with the exhaust system and can potentially give you gains of 70-150 horsepower. A supercharger is connected directly to the engine intake and could provide an extra 50-100 horsepower.

Will a 4-71 blower choke a 468?
Firstly the 4-71 blower will be out of air even on a healty 350. You can’t simply rev the blower higher because its air flow efficiency will drop real fast after about 20% overdrive, in other words, this lil blower will choke a 468″ for sure.
What is the best blower for a V6?
It is the perfect choice for V6 and small V8 applications and will replace virtually any 4-71 GM blower. Additionally the BDS 471 features the company’s latest 3-lobe, non-helix, rotor design which allows the blower to push more and cooler air than that produced by its predecessor.
