Which fuel pump?

[Blown353]

Something for you to consider... at 20psi of boost / 1000hp expected on a stock displacement LS1 I would expect you to be over the suggested 80% maximum duty cycle of 75 lb/hr injectors. 80% duty cycle through 8 75 lb/hr injectors will flow 480pph of fuel, which is enough for 1000hp at a .48 bsfc... that is a very efficient number for a street-oriented turbo build. Most "street" turbo builds usually end up somewhere around .55-.60 BSFC as you're running pump gas and have to keep the AFR on the richer side of things. You'll probably want to step up to 85 lb/hr injectors at the minimum. Keep a close eye on injector duty cycle with those 75's.

Another thing-- Aeromotive Eliminator pumps are LOUD-- make sure you install them using as much vibration isolation as possible and if you value your eardrums don't install them in the trunk!

On other installs I've helped with we've had 1 out of 3 Eliminator pumps that we purchased fail; it still pumped fuel but nowhere near the advertised volume above 40psi; it was bad right out of the box and I noticed it when I was flow testing the fuel system before starting the car for the first time. All installs were using Aeromotive's suggested -12 size line on the suction side. Make sure your fuel tank has a minimum 3/4" ID pickup if you intend on using an Eliminator or you will smoke the pump from cavitation.

Magnaflow EFI 600. When its not on your car, you can use it to water your lawn (flows big volume at all pressures). And its fairly quiet to boot.
