Thread: E-Force supercharger

Tweet

Edelbrock has a new supercharger, E-Force that as stock puts out 5 lbs.of boost. Now they claim no valvetrain upgrade,no special bottom end work, and no compression ratio adjustments and it will run on 91 octane gas. It's use with a 800 cfm carb and its an Eaton postive displacement type that can be bolted on a stock engiine with no additional modifications. Has anyone tried one of these? Seems a little far fetched to me.

Sounds right to me. Ever since I was old enough to read Hot Rod magazines, guys have been bolting superchargers with mild boost onto otherwise stock motors. 5 lbs will boost hp/torque by 25-40% over naturally-aspirated, depending on heads used.

Tech your right on that but what I forgot to mentioned is that they say you can run from anywheres of 9 to 9:5 compression which to me would say Kaboom to your engine unless 5 lbs. is not enough to worry about.I never had a supercharger but everyone I've talked to says to run them with low compression of 7:5 or 8. Now this blower is small at 122. Now with a programable MSD ignition, they say it's virtually impossible to detonate this blower. is it because of its size and the small pulley you would have to use to get 5 lbs. of boost?

According to Blower Drive Service, you can run 4 lbs at 9.5:1 on pump gas and 6 lbs at 9.0:1 on pump gas. With spark control and maybe water injection, I'm sure you could go more boost than that even, depending on crank, rods and pistons.
