hey guys...i just dynoed my dawg.....she made 587rwhp and 478rwtq at 20psi and on pump gas....afr's were around 11.5~11.7.

@~15psi she made 516rwhp and 418rwtq.....on pump

i was just wondering why the torque was soo low compared to the hp...seen such differences only at higher numbers....oh well..very happy with the results!!

hey yogi, i think the dynapacks that we dyno'd on read lower torque numbers compared to a dynojet.

Nice numbers, question...where did you get a .84 housing for a T78?

but when we dynoed at bpu levels....the torque seemed fine....maybe the quick spool in the stockers made a difference...

not really....you only made decent torque when you made~430 after running very lean with overboosting. i forgot your exact number. tim and i made 390ish and 388 respectively. i think it shoulda been higher that especially considering the way our cars ran compared to yours @BPU.

we were all shocked and happy for yogi when we saw those numbers. what is the highest dyno number for a T-78 on a stock motor other than 264 cams @ 20psi?

20 psi on pump is a tad high IMO, but congrats nonetheless on the dyno runs.

Also, why did you post this in the Drag racing section!? :lol: ;) A Smod will probably move it. :)

Very nice numbers but I agree the 20psi is pushing the token on pump gas.

Looks really good I love those numbers. I thought the T-78 can produce more Hp numbers than that or am I dreaming? How much hp @ the flywheel yogi?

The numbers were done on lower boost, the turbo can hit 30+ psi but I am assuming he hasn't pushed it that far yet :)

i wouldnt know the flywheel hp numbers...for that the motor has to be out of the car.....the chart depicts the wheel horsepower!
