Any video of the with and without the blip?

I would video the rear in action to see what was happening?

Have you noticed if weather conditions effect it at all?

The bottom graph is what it does most all runs. No shock setting, tire changes really effect it. It will print tickets then throw out one that is .015-.02 off.

Then it ran the top graphs early in the season it ran 5 runs and varied .0007. can't get it to do it again.
Track temps were much cooler.

Yes when no blip it dead hooks. When it blips there is about 1 revolution of the tire out about 8-10 ft.

Not sure what type of rear suspension you have, but i rin leaf springa. But i chased an issue a while back where the car would do what your describing. It turned out i didnt have enough shock travel and it would top out and unload the tire. It was intermittant and drove me crazy. Maybe something to look at.

Good luck.

re-post the photo's of the two graphs which include the rpm to the left. The flash stall and drop back stall will be helpful towards seeing what's going on with the power.

The stall tells about the power, or in other words the conditions, for power.

Can't see the rpm, so I can't see the difference in power/conditions between the two runs.

Current graph almost 109 mph.



This graph will be the new graph (red drawn line), with the new 9" converter 6.41 dial at 112 mph on a 8.5 x 26" tire, high gear only

The first graph stall is at about 6200. The second graph is with new Abruzzi converter 8inch that stalls at 6450

Put it in high gear right after it comes off the transmission brake.

Or dial in the chassis for wheelspeed at the hit.
1. tighten the front end 2. loosen rebound a bunch & tighten compression a bunch, on rear shocks.

I have a couple people I'm interested in skinning up, but I want to make it fair for them. So I'm gonna do a 8" slick x 26" tall to make it fair for them, no excuses.

My truck does the same exact spike at the shift. It has never affected how it ran, nor how I dialed it.

This graph is interesting at the shift, in the car it probably feels like it shifts hard, but it looks like a mistimed shift on the driveshaft graph, like the band is slow to get off the drum.

Then when finally does, it spins the tire.

How much line pressure in gear, above 2000 rpm's?

Bill, am I reading right that you are shifting about 7500 and falling back to 7200ish?

No, shifts at 7000, falls back to 6200ish depending on the track.
