Took the car to Ramseys performance in tampa this morning for a new dyno tune.They did a awesome job,nice clean shop and he was more than happy to answer any questions i had.

466rwhp/503torque @ 11psi

I have an issue with my gt500 pumps, they were running out of steam at 466 and thats not normal so i have to pull the pumps and figure out whats going on. Should be a easy fix once i find the problem. Planning to bump it up to 14-15 psi once i get it sorted out.

Sweet! Keep us posted on the pump issue.

thats crazy. i have that ghetto dual pump setup from procharger and a 40V BAP with 39# injectors and i am making 498whp and i am just barely tapping out my pumps at 6500RPM's. You should be able to make well above what i am putting down with no problems.

What size injectors are you running?

I'm glad to see everything is back together again!

52# injectors,im only running it to 6k rpms.after doing some reading,im hopeing it is just a blown fuse on the second pump driver,that would be sweet and easy to fix.the tune is pretty conservitive.i dont want to have to worry about another blown motor,once i get this fuel pump issue resolved ill push it up to 500-550 and then im done.i may start taking it up to 6500 rpm.

Hopefully everything works out. I know its been what, almost 8 months since that horrible day on a 12.1 pass? Dont forget the guy who got under the trailor in the dirt to help hook up the rear axle! lol

one eyed willy

yeah,thats very much appreciated buddy,ill make sure to take you for a 11 second pass when we get to the track together.

i should have the fuel pump issue resolved tomorrow night or sat. morning,im thinking its the power wire going back to the second fuel pump driver.

the car hits 500 torque mark at 3500 rpm.peak hp dont mean much,mines coming in early and making good power all the way till 6k rpms.

Good Job One Eye!

You probably know this already or have done the research, but 9 times out of 10, any issue with the GT500 pumps seems to be electrical. Since they were working good before, I would lean towards one of the fuses being blown or a ground coming loose.

I thought I had issues with mine so I tried to rule them out one at a time pulling one FPDM off at a time. Everything worked fine so I ruled out the BAP or the pumps or the FPDM.

I'm predicting easy fix for you.
