Default Shooting for 9's @ 140, 3300 lbs

Running 18psi on a cast 7875 gen 3 4.8 in front of a TH350 in my Volvo 240. 8.8 swap has been done with 3.27 gears. Basically all stock suspension, cheapest ebay shocks I could find in the back. Completely blown out shock in the front. Upgraded brakes so I can stop.

Fuel setup is Deka 80's, single Walbro 450, -6 fuel line, ECS Voltage booster(17.5v when triggered) and e85. Currently holding rock solid fuel pressure to redline and around 88-90% duty cycle around 11.4 AFR.

My current best is a 10.34 @138.5mph with a 1.80 60' at 19psi tapering to 17.5psi(out of wastegate spring).

I think the setup has 9's in it at it's current power level. I really want that 140mph slip though. 9's would be icing on the cake.

I guess the question would be if anybody see's any real issues hitting these goals with these parts? I'm going to continue to push them to find the limit.

Is the 4.8 all stock ?what is the converter flashing at ? And your losing at least 3 10ths on your 60 foot just a good 60 would put you in the 10 flat what rpm are you shifting at ?

Its a cam valvesprings engine. Everything else is stock. 216/220 .565 cam and PAC 1218 springs

Brakes cant hold enough to hit stall speed on the converter. Im guessing 3400-3600 though.

Currently shifting around 6500 bc it really starts to fall off after that. May start shifting a little earlier next time out.
