the first one Here's the story-
Last week, we ran 9.67 and found that the injectors weren't cutting it. We may have been able to squeeze a little more out of them, but the plan is to run 8's, so out they went in favor of a larger set.
The new injectors flowed so much more than the old ones that we put together a whole new PCM file with radical changes for fueling. The first pass was a test run and went 9.88 at 140. Turned up the boost and adjusted the fuel and went 9.603 at 145.64 with a 1.49 sixty foot. Much to my dissapointment, the injectors have plenty of room, but the fuel pump was not keeping up at all and the air/fuel fell to 14.9 to 1 by the end of the pass. For the 3rd pass, we made some fueling changes to allow the pump to run a lower pressures with longer pulse widths. This was good for the following- 60' - 1.4891 330' - 4.0390 594' - 5.7468 1/8 - 6.1317 mph - 116.90 1000- 7.9311 mph - 135.86 1/4 - 9.4638 mph - 146.65
The run was bitter-sweet because the fuel system still isn't there. With the fuel pressure trickling down below 40 psi by the end of the run, the air/fuel ratio hit 14.1 as I went through the traps. The good news is that the car is running great and should be 9.20's capable at 26 psi with more fuel pump. The plan has been to hit 8's at 30 psi and we are still on track for that at this time. Also, FWIW, we now have over 30 runs on this car with no major failures. I'm loving the ZZP transmission. Of course 800 lbs of weight reduction is not to be overlooked
and teh second one ( rwd GP)
Chris Hoenles took the 3800 1/4 record earlier tonight at Milan only to be out done my Matt M at US !..! dragway......so now ZZP cars own the top 2 spots on the 1/4mile list....
Here are Hoenles numbers:
60'- 1.287 330'- 3.891 1/8th- 6.081 MPH- 110.84 1000'- 7.9849 MPH- 129.41 1/4- 9.6017 MPH- 138.60

"the plan is to run 8's"
I am completely overwhelmed by the mere thought of that. Impressed does not even begin to express how I feel.
I know the car is tweaked to all hell but still, to get that kind of performance is insane!

One of the really cool things is that this is on a stock L67 bottom end (stock pistons, rods, and crank). He got it from a salvage yard.

That's awesome. I can't believe that a v-6 front wheel drive can get those kind of numbers

Agreed on the "forgotten muscle car" note. http://www.gm.com/company/gmability/adv_tech/100_news/pop_mechanics_award_093005.html 32-bit CPU is impressive as well as the variable timing and intake. I am glad GM is getting into the VVT world. However, I won't say its phenomenal like Popular Mechanics claims it to be. Seeing the horsepower numbers made my head go down. 3.9 = 240 HP N/A. Nissans's 3.5 already gets 270 and the ol' accord's 3.0 has 244 HP and 211 TQ. The 3.9 does beat them on low end torque (240) in comparison to the competitors very high end torque, which should have been mentioned.
