I would throw out the 10.26 run, may have lost traction somewhere to skew times. So then you ran a 10.22, 10.23, and two .25's on the brakes.

I upped the fuel pressure to about 6.25-6.5, see if that helps bring down that curve early in the run. I'm trying out my 275 Drag RADIALS TOMORROW, GOING TO BE 90+!

Well I couldn't get it to hook on the radials at all, it was initial hook then spin everytime, tried different shock settings, air pressure and leave rpm as well as off idle etc. But I think the curve is better with the more fuel pressure

Yea , It was a little challenging lol.. I think if i get a good shock up front to slow it down alot it will work, heres a video and u can see it spins when front tops out, it is stuck at the hit. I cant give up , they have to work for drag week lol. I have a set of older QA1 drag R series shocks,their 12 way single adjustable for the rebound and a fixed comp, and they get tight at full setting, I think ill try them at 6 and see what happens next week.

I forgot I put a 1" rubber coil spacer under the bottom drivers side coil when I was having a sagging problem in the front and it ended up being the back shackles before I put those global West things in I've got over 5 inches of travel now and probably even more once it settles in n I drive it. That will be huge gaining that extra travel

Looks to me like its "porpoising". DR's can work at least as good as the same size slick - look at all the 7 an 8 second cars with them. Radials don't like as much hit downward because the sidewalls are stiffer than slicks and they will rebound. I would try stiffening the rear extension. As long as it gets good initial bite it will help. After that you may even benefit from a stiffer compression, depending on the track. Sometimes you have to take a big swing at it to tell what it wants.

I agree. Stiffen up the extension on the rear shocks, and you will not bounce on the tire. Slow the front end rise down to lengthen the apply time, and you will be good to go.

I tried stiffer on the rear EXT in the middle on my afco's, It didn't seem to help, spun worse actually. Maybe I should've went even tighter? I had the comp at full tight
I can't slow the front as i only have calvert 90/10 needs a DA Shock, which i'm looking at some vikings now. Im sure gaining some extra
travel will help also now, and even more when i can slow it all down.
