98intrigue Its crazy to see you have me in the 60-70, 70-80, then 70-90. After that is when i pull on you and im at like 5k rpm. Are you lift shifting, stock trans? I am stock and just blew my motor and trans last roll race at 1100hp 12psi setting lol

Since it's ET comparisons, it has a lot to do with momentum. The earlier in the run that you break the G trace, the bigger impact that will have on the end ET. So you not shifting twice has a large impact compared to someone who is - whereas if you look at just the metric of constant accel vs constant accel (not a lot of that in that short of a data set) you'd see the difference in power/feel. Heck, in just the last 10 MPH gain (60-120 vs 60-130) you are over .3 quicker than Ryan simply because you're not shifting again at the end of the run.

DA was terrible. I have a comparison from a better DA last November but I didn't run it to 130 then, just 120. It went 60-120 in 5.46. I'd say with similar DA this car would be 6.50-6.60ish.

*** I know it's invalid, but just by .01%. I'm counting it.

New transmission, new 60 - 130.

I wonder if the 4.10's are actually hurting you. Any pics or clips of the car?

You must be making around 650rwhp? Very strong

This was from this past weekend. The good air helped even more than I suspected. If my shifting was as good as the run from the summer it would have been even faster. There was one change in the setup however: this run was with a ported Gen 4 intake. The previous run was with a Gen 5 intake. And yes, the car made 647 rwhp with the Gen 5 intake and a 3.73 gear. I will be switching back to the Gen 5 intake and doing some testing for comparison. I will report back with results.

I have wondered that too. After this past weekend's run I don't think its hurting it too much, but there is always room for improvement. I wish I could do a 60-130 in 1 shift to see how fast it would go.gen4intake.jpg

Thanks. It's been a lot of fun and its only going to get faster.
