Id have to say its weather...your 60fts were similar in two of your runs..so you can't really count that

Hmmm...
The thing that stands out to me are your 1/8 and 1/4 trap speeds. You are picking up 26mph on the back end, which is a lot. The 1/8 traps are low for a car trapping 107 in the 1/4. This indicates to me that you could trap even higher in the 1/4 with a better 1/8 pass. I'm wondering if your shifting is a factor...

well, in the video he is spinning a little from first to second. that will slow you down.

Your losing alot of momentum when you spin early in the run. When I used to run Nitto dr's I would spin alot on the 1-2 and 2-3 shifts. I switched to MT dr's and my et's dropped .2-.3 consistently with no other changes.

edit: I should add that my 60' times also improved, but even on my runs where my 60' times were the same as with the Nitto's my 1/4 et still improved by .2-.3

Have you changed your shift rpm? I know on my car any thing over 5600 and it picks up MPH, but loses ET. I have tried several times even on the same day back to back passes.

Sounds like you've beat your clutch to shat and it's not biting as hard as it once was.

Just kinda sounds....slippy... Idk.

A little wheel spin can negatively effect your ET, but can actually increase your trap speeds. I guess the question there is how much wheel spin is he experiencing?

No question in my mind that he can trap 108-109mph with a better 1/8 pass. I agree that ET Street Radials are superior in grip to Nittos. A good DR is a very good way to address excessive wheel spin.

I think it is my 1/8 mile also that is killing me. And my clutch is on it's way out maybe it is slipping in the lower gears and once it stops slipping after the 1/8 it is able to push me into the 107 traps. I did spin a little on me take off and 2nd gear change but I don't think enough to real kill my time plus my 60ft isn't that bad for being on street tires
