Not sure on power but were in the 90% duty cycle on the 8.46 pass on c16 at 3700 race weight

I think its more that i am out of fuel pump than injectors. With the bigger injectors lets more lower the base pressure for the pump so we will see when it hits the track or dyno.

I was maxing out my fuel system on race gas last year so upgraded my injectors from 127lbs to 2000cc from Fuel Injector Connection. Hoping to hit the dyno next week to see what it will do on pumpgas 17psi to compare the results.
Holy crap, they FINALLY did it? I have heard about this 100mm unicorn for years but they kept putting it on the back burner because it wasn't legal for class racing. Can't wait to see the results of the new combo. Goodluck!!!

I can see the lines for the curve but I can't see the before and after numbers. What were the HP and TQ figures?

Very solid gains! You can really see the improvement in the upper rpm of the graph from 5500 rpm on with no major loss down low that I can see. Are you going to update the cage to a 7.50 cert or just try to run 8.50's on a lower boost level?

Nevermind on the weight. Just saw it, 3700lbs race weight. That is one heavy car! Very impressive turning out those numbers with it being that heavy. I would assume you would need more power than that to get sub 8.50s but you must have a dialed in suspension.

What are you're goals for the car this year? What more are you planning on doing to the suspension?

Nice work, good to see other heavy cars getting very Solid numbers even on 93oct, did you have any meth injection for safety? Nicely built, I'm assuming you street drive since pump gas use and all, how responsive is the motor, assuming the Converter stall helps with that too... Great stuff
