Which fuel pump?

[ttchevelle]

Im running a tt ls1 75lb injectors 20 psi of boost intercooled. My question is I bought a aeromotive eliminator pump that will require a pump controller on the street. Should I stick with this combo or should I switch to a regular
A1000? My horse power goal is about 900-1000. Thanks!

I would run the controller with either of those pumps.

Thanks for the info. I would assume its best for the pump so it doesnt overheat right? Nice car by the way! Im in the middle of trying to find header fabrication in socal that will weld stainless alot of guys will only work with mild steel. How lony did your car take you to finish?

thanks. There's a day by day build thread here; just under three months including all the turbo fab, re-wiring the car, etc. Just me working on it, other than having a friend help with welding and fabbing the downpipes.

Tom Nelson has a great guy down there for welding stainless. Here's the 321 stainless headers he built for me:

If you dont mind me asking whats the $$ for these headers?

you'll need to contact Tom at Nelson Racing (http://www.nelsonracingengines.com)

Keep in mind that some ECUs/ECMs have controllers built in, and you may not need an additional controller....

Mark over at bent Customs can do some incredible work.

I am curious if a 2000 chevrolet camaro pcm for an ls1 has an internal controller for the fuel pump or not any ideas?

take a look at the weldon pumps.

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.
