i dont know but ever since i put all the parts on my truck it doesnt act rite untill about 120 degrees???? i dont know if its the pump or something else but if i were to put a new pump on it what would be the best pump??? im lookin for about 500+ at the rear wheels in the end!!?? im gonna prolly be runnin like 150's sticks and possibly twins!? any suggestions?? o yea by the way my fp never went under 5 psi until i got the air dog and now its set at 16 psi constantly!!

 

check to make sure your pulse monitor is not set on warm up mode you can set it to not add power until coolant gets to set temp

 

I dynoed 506/1026 with a bad clutch and a dying vp44...I'm running 150s, tst comp, edge comp, and a 64/71/14...should be able to hit 500 without going twins, if you wanted too, but twins would definitely help, and help keep the smoke down.

 

I dynoed 428hp with a little hx35. 40hp sticks, scheid lightning VP44, FASS and edge/juice attitude. I have since added 120hp sticks and a phatshaft 62/65/14. Hopefully I can get down there on fri and spin the rollers again.

I highly recommend the Scheid Lightning Pump. Put it and the FASS on at the same time back in June 08. Have almost 50,000 miles on it with no problems.
