I have a 1993 camaro that I am setting up for twin turbos. I am not looking to make 1000 hp but may make around 800.

Here is my question recently I had to drain my gas tank to rid it of four year old gas so I decided to let the fuel pumps do it for me unhooked the lines and ran them into a five gallon can then direct wired the in tank pump and my t-rex boost pump to run. I expected a very violent stream to come out but all I got was a trickle I know the pumps are working right the car runs and the battery was charged. even so it took about 10 minutes to fill a 5 gallon can gas just trickling out like a garden hose on low.

After observing this I began to think that the factory line has a lot more potential than I thought and with the right pump it may be able to supply enough volume to support 800 hp.

Anyone who has ever cracked open a presurized line sees fuel spray all over but this is like taking your finger off the end of a garden hose you see the pressure not the volume. I know everyone is into trick fuel systems but is it really needed or is it overkill?

I'm running 800HP at the flywheel (BSFC = 0.52 #/HR/HP on nitrous), through a -6AN line. That's roughly the same inside diameter as the stock 3/8" plastic line.

I made 700rwhp with stock lines and regulator.

what did u have for pumps? oh yeah and did u have stock fuel rails also. just curious.

Dual Bosch 205 LPH pumps, one in the tank, one off a sump on the back/bottom of the stock tank. Stock rails, but modified to feed a -6AN line into the back of each rail, and a -6AN return line welded to the cross-over line at the front of the rails, routed to a Weldon AFPR mounted under the cowl.

Like Fred said a 6AN will work but I did over kill for a big block some day so I did 8AN (1/2").

I burn one gallon of 114 per 1/4 run, of course that is some idle time and back to the pits.

The fuel pump is the aeroquip 1000, with a hypertech regulator.
