Do I need dual pumps and 8an feed 400rwhp + 200shot I am going with a new setup on my Ls1 Rx7. Below are the mods I had then and I will list the changes.
Mods:
FMS F5 Cam 224"/228" .588"/.576" on a 112LSA
Stock exhaust manifolds, intake, t/b and heads
Mail order tune
2.5" y-pipe to 3" Racing Beat Catback
3.5" Aluminum air intake
Aeromotive FRP
Stock fuel lines front tank
Walbro 255 intank
150hp Wet shot
Z06 Clutch, stock shifter
Full weight, 5/8 tank of gas
60FT - 1.663
1/8 - 7.410
MPH - 96.41
1/4 - 11.4
MPH - 121.65
Changes for this year.
SLP CNC heads (just outflow LS6 heads 270CFM)
JTR 1 3/4" Long Tube headers
3" y-pipe
3" Stainless exhaust
EFI Live tune
Typhoon Intake with 85mm TB
Billet Fuel Rails
Direct Port Nitrous setup (150-200 shot not sure yet)
LS7 clutch and flywheel
I am hoping to put down 400-420rwhp. Then most likely spray 200shot. I feel I will be maxing out single wablro 255. I should put down 600rwhp on spray. I was planning on making up a dual intank walbro 255 setup. With a y-fitting in the tank with a 8an bulkhead fitting on the top going to a 8-an feed line to the FPR then 6an to the rails and use the stock 3/8" line for the return out of the FPR. Now I feel this setup will be more than enough for the power and the cheapest way to do it. But even though it is still the affordable way it is pricey. Does everyone agree this is needed. Could I get away with the dual pump and runing the stock 3/8" feed line. Here is the cost for the new fuel system
255 Walbro Intank - $90
20ft 8an hose - $75
Summit 8an inline fuel filter - $60
y-block for intank - $25
Bulkhead 8an 90degree - $15
$75 rest of an fittings
Total - $340

Yopu could get away with one of our dual Walbro kits as one pump will run all the time for the motor and the second will come on with the nitrous system. You will be fine with the stock lines at your current level. Can always add our line kit once you want more power.

Ya I figure I can get away with 2 Walbros and the stock line.
But you are aware I am taking about a 93 LS1 Rx7 not a F-body. Cause I dont think you sell a dual pump kit for a Rx7. Thanks
