Tweecer Dyno tuned Thursday

[Jack's95gt]

Running 6-7 psi boost the best pull was 422.60 power / 453.99 torque on a Dynojet at Swarr Performance. That was done with a stock A9L tune. The ProM MAf was right on and no air/fuel changes was needed.

Good numbers with low boost. IMO, the less boost you need to make the power, the better.
Should be good for easy low 11's.

Is what you are saying is that your car ran best on the factory computer, instead of on a tweecer tune?
I've been trying to tell people this forever. I have seen it done at my buddy's shop and almost every time, the factory computer beats the tuned setup.

Definitely solid numbers man, very nice

I'm going to see what that translates into a 1/4 mile time this weekend. I'm doing the true streets at Atco.

Nice setup. With a short block like what you have, I'd be tempted to throw a LOT more boost at it... But that's just me.

The best run was my 2nd with a 12.014 ET and a 118.36 MPH trap. My goal was to get into the 11's and I just missed it. I added some more Methanol injection which could have hurt the performance some. I'm going to drop to a smaller SC pulley and remove the spare and jack and I should be there. Car #30 on the attached timeslips. BTW the car with me weight in at 3192.

118 mph suggests you have a pretty quick car, probably 11.50 or better capable with traction.

I'm babying my car with a let out the clutch and floor the gas and then granny shifts. The 1st race I had 25 psi in the Micky T's and I spun in 1st throught 2nd and then in 3rd. I dropped them down to 18 psi on the 2nd run and they hooked. The 3rd run I dropped them down to 15 psi and once again they hooked, but I heard noise and I let up off the gas and I got back on it. The car seem fine and rode fine on the way home. I just need more practice at it at test and tune nights. It tough to race a manual transmission cars.
