I just watched some of the vids, and it sounds like it shifted 2-3 quickly on some of the early passes.

From what I can tell it's either your shift points are off Or ....
Before I say the other possibility, (do you have a multi disc converter?)

I'm going to steal your converter out of your car and go 11.49 next fall with some awesome DA.
Haha! I'm gonna steal your gears and put them in my car and break all the records! Then I'm gonna put your car on a diet, then I'm gonna drive it and THEN it will run 11.39!!

I see now and yes you are right. Ut would be hard for him to see 11's in stock tires, and a 1.7 on stock tires at his power level is gonna be almost impossible!

I guess I need slicks, gears, and a little slim fast in the gas tank to keep up with y'all.

Thought so, it also could be your converter locking very early. You need to data log it to see exactly what it's doing.

Either way if its shift points or converter lock up mph, it needs to be adjusted!
I hope your tuner has the ability to tune your converter. Not all tuners can! Trust me I know.

On the street when driving in manual in 2nd or 3rd when I shift into those gears the car surges very noticeably. I will shift and a few seconds later it will surge and drop rpm. It does it in s mode but not as hard. I don't know if this is related to what you are talking about. He said it should lock until 4th.

What do I need to log my runs?

How where you shifting it?? In S and let it shift on its own?? In M and paddle shifting it?

I just noticed that towards the end of the night, it wasn't doing that short shift or converter lock up like it was earlier? Did you change your launch technique or anything?

Always in s mode.


As far as surging in manual it happens while running around 40 to 50 and accelerating and then letting off. Same in s mode. Accelerating and letting off. When the rpm drop a few hundred it will surge. Almost feels like when 4 low in my truck and running along and let off. How it feels like grabs. Idk. Feels torquey. I don't know how to describe it.

And in the later runs I wasn't holding as much rpm on it.Off throttle and rolling into it. In the early runs I was holding 1500-1800.

I'm betting its your converter! Mine did the same thing except it was in 2nd gear. I would notice after it shifted to 2nd and rpms were climbing it would suddenly drop down about 400 then start rising again! I had never ran a multi disc so I didn't realize right off that it was just Bc the converter was locking in 2nd.

Too make a long story short, Rhino fixed that problem for me instantly.

I will get him to check when he gets back in town. Now that I have my go pro I'm gonna make a video to show him.

Help me out on this logging stuff. What do I need?

I would get the car to hook first, then look into the tune.

So the spinning and high rpm from that is making the shift earlier than needed and causing premature lock up?

Tuning software and a laptop or handheld. Your tuner can set u up I'm sure.

Agree John, your biggest issues messing with your ET's Jeff is TIRES TIRES TIRES! You are having to baby that throttle to keep from spinning! You need what I have. 18" Vette rims with MT ET streets! Then you can hammer it!

When my car spins a ton on a run, my shifts don't necessarily sound right.

Correct. When you spin the tires it messes everything up. It'll shift in weird spots because of the sudden jump in rpm/mph. When I spin it will shoot the rpms up to 73-7400.
