You log trans temp? Maybe trans temp is climbing since you are running in high gear?

And I would put a go pro in it like I suggested on YB before I let someone else drive it.

They aren't climbing in a new car and cutting 00_ all day either.

The video will tell you what you need to know.

I don't keep a log book of trans temp but I do have a gauge and regulate it.

Good idea to monitor transmission temperatures.

Hotter (Thinner) fluid should stall higher.

With that said if the trans temp was hot enough to change REACTION time significantly then I think it would probably effect the ET of the run as much and more.

A new solenoid is cheap easy thing to try and first thing I would do here. The do get dirty and sticky. They still work just not as consistent.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

I just found something that I'm not sure would affect anything but maybe. When I started running high gear I eventually stopped lowering the wheelie bars from transport position. I just realized that with them pinned up the car will only squat about an inch and the bars hit the rear valance and stop it from moving. I'm not even sure it squats that much in high gear but my guess is it does.

I will pull the solenoid from my spare trans and take it with me. I have a spare but it's pretty old and been used by several others in a pinch.

Inferno, do you have a bump down button in the car?

If you don't, and your box has the capability like most do nowadays I highly recommend you put one in it.

Yes I do have a bump up and down but during this run of crappy reaction times I have no idea if I'm late.

I would try shifting on time at .3 out. I have a feeling your chassis isn't working consistently leaving that soft. I know when I did the same thing years ago consistent et and reaction came from leaving in low gear and shifting to high immediately. I raced you last weekend by the way....I was dialed 5.23 Smile

The car ET is deadly consistent, the driver is struggling. So you are the one who shoved me into the left lane. Smile

I went out today and ran low gear with a new button / switch mounted in a different way (thanks xlcr77). Made 4 passes, reaction times were .013 .004 .010 .015 then grenaded the ring and pinion on pass 5 at the hit.

I've been chasing a vibration on decel most of the year (think I found it). Shortly after letting out of it I would get a buzz or vibration for maybe 1 second (nasty little vibration) and then go away. Felt like the driveshaft was vibrating. Have checked things over several times but never even thought about ring and pinion. Just glad it happened at the hit and not on the big end even though it didn't lock up.

I thought the problem was inconsistent reaction times in HIGH gear? Do you think leaving in low gear or the new button mounted different was the issue?

I was having reaction time issues and been running basically all high gear so not really sure if it was only high gear or not I guess. I guess now I will go back to high gear if I get back together this season and see if it is cured. But with that said I really like the new switch position and different way to activate it.
Looks like 1/2 of my ring gear bolts fell out and then the rest sheared off. No sign of loctite.
