Thats quite impressive numbers for a 7875. I didnt think they would make more than 750rwhp....makes me really wonder what my billet 7875 is making at 22psi on a heads/cam 5.3.

- Dart LSNext 388"
- Tick Stage 2 LS3 Turbo cam (small for this set up). Brian Caskey ported LSX-LS3 heads. China Sheet Metal Intake.
- Forced Inductions S491/102 T6 1.32
- 1008 RWHP 23 PSI 18.5 degrees E85. Unlocked 4L80E and Mustang Dyno.
Should have a lot left in it. I think this turbo has another 10 psi to give at minimum. We stopped because the data log showed momentary drops in fuel pressure but was maintaining AFR. Long story short it was dropping battery voltage into the 11's and turns out that is bad with 3 electric fuel pumps lol. Fixed that issue now though with XS power alternator and 14V battery. Fuel pumps like 16.8V now! Been 6.02 @ 119 with a 1.39 60' a year ago on about 16 psi total and soft down low. Adding a legit cage and some chassis parts this winter and plan on getting after it big time this spring. Hope to go easy 5.50's. Edit: This is in a fox mustang btw not an F body.
