Bigger pum at----%
« on: May 31, 2018, 08:39:22 AM »
Looking at nitro notes and 90% of my setup is already good for bigger loads if I want. Pump is my biggest limit right now. Wondering how far before need bigger pump.

Setup is:
        482 ci Hemi TFX block BAE fuel heads
        12.65:1
        296 @ .050 cam 116* CL and 64* overlap
  195 cranking compression
     MSD mag 12
  Enderle bird catcher with K style BV
   sheet metal intake
  pump DSR dual gear with 6.85 gpm at 8000(4000 pump)
 4.10 rear
 1.69 low PG with hi/low setup so leaving in hi not problem.

 I know converter setup means either change or new(new wins) since stall is 6600 in bracket trim for alky setup.

Spud in Nitro note you mention trans cooler.Did you use a hyd. quick coupler and just bypass when in race mode?
Relecting obama is like shooting right foot because it did not hurt enough when you shot left foot

Yes, hydraulic quick couplers. It's just plumbed into the pan so there's no need to bypass anything...just unplug. The stuff in the pan gets cooled quickly and we roll the motor over with the starter and the plugs out to swap out what's in the converter...then run the cooler some more.
