Ok. So the ask is simple. If you have means to log your driveshaft please share.

I've been fighting this blip here on my car. I was able to get rid of it for one track early on but since nothing seems to resolve it.

I hear some say that big tire faster cars you will most always see that. I know I was able to get rid of it at one track but all future efforts failed.

At times the car is deadly even with it. Just curious what others see.

Here is the graph with blip...

Here it is without. That is several runs overlayed

Would like to see other graphs. Any info like ET, tires, SLR, converter, repeatability etc would be awesome.

I have that blip. Now I'm a footbrake car so I don't know if I can be a great comparison but you can see my 60' times are pretty consistent. I have my wheelie bars set pretty low and it bounces me up on the tire. I have the need to keep the front down. The track was just okay at this race, since it was right at 100° air temps. D06 Hoosier 14x32 I hope you can see the increments listed.

No I usually race opponents in other race cars. But in this instance I'm asking for driveshaft graphs.

Can’t help you, a driveshaft rpm blip on a graph is meaningless to me, my cars are deadly consistent!

Try stiffening the compression of the rear shocks and adding a little air pressure to the tire to clean up the drive shaft. It could "fix" the issue, which COULD make it faster, but it might come at the expense of consistency. Some of the most consistent cars out there, have the ugliest drive shaft curves you have ever seen.

EXACTLY, that's why all that matters is the time slip!

it doesn't especially for a 130 degree track but it's ain't perfect either. Maybe the blip is the reason it picked up .001 at the 330. Laughing Hard

You can know Ed's never done anything, because when wins a few 5 & 6 round races at his local duck pond, against opponents who are 040 in the final, he thinks he's done something.

3 finals on 20 entry's ... big whoopy chit. opponents 040 in the final. Laughing Hard

For those that have posted graphs and info thanks. Mine are in first post for whoever asked.

Both with blip and when it didn't say one track in cooler temps. Even with blip it's consistent 90 percent of the time. But that gets you to the quarters or semis.

I connected the two runs, so you're saying the top run is what ya want, dead hook. Why don't ya purposely put some shock settings for some wheel speed, maybe it'll print tickets.
