| One other thing not related to tires here. You pulled out 8* timing for .8 seconds and car went faster. I would try lowering timing some for full pass. From my experience many people run way more timing than needed. I was told on my motor to run the timing at 38* and I did for a while and it worked okay. Then I put motor on dyno and found it made a few more horsepower at 28* and so that is what I run now. While it only picked up a few horsepower with the lower timing I feel it is a safer tune up and easier on the motor to. You have tire issues right now (Hoosiers)but the fact that when you pulled timing out the car ran faster is something to keep in mind after you resolve the tire issues. https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. 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. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion |

I will bet! The Purple chit will knock even butcher's teeth out with his gums flapping...just stay on the gas and see the purple parts eaters in action.
I will personally loan a set of big bubba with beadlocks to anyone who wants to see the difference...for the whole race or just one pass...just lmk!
The Bubba won't shake in the burnout...I don't work for M/T, I am not a distributor, I dont sell M/T, and I approve this message.

Looking for some recommendations regarding tire shake after testing a new setup this past weekend..
245" swing arm dragster, 4.10 gear, 12 degree 632 (steel block, 32* of timing as recommended by Sunset) - never been on the dyno but I would guess in the 1200-1220 hp range, Hoosier D06 tire (around 80-100 passes on them) on a 15" non beadlock rear wheel. We are using a Grid (brand new to us) to control burnout RPM (6600), launch RPM (4400), and launch retard (8* out for .8 seconds).
The tires are shaking in the burnout and really hard at the end of the burnout. Rear tire pressure was at 5.5.
-The first pass we had all the timing in and the car rattled the tires for ~150 feet. Went 1.06 to the 60, then 4.59 @ 153
-Second and third pass we pulled 8* for .8 seconds and the car rattled for ~80-100 ft and went 1.06 then 4.56 @ 154.
Few questions:
1. We are going to switch to 16" rear beadlock wheels, but what tire would you guys recommend for this setup? Would the MT 3190w be good for this setup?
2. During the burnout, the motor sounds very abusive bouncing off the chip at 6600. Are most people with the Grid just setting the RPM high (7000 for example) then controlling the RPM with their foot (around 6600-6800)?
3. What launch retard seems to work well with these combos? We have not done much experimenting but if anyone has something that works well for them, we would appreciate a good starting point.
Any other suggestions or tips would be greatly appreciated, thank you all in advance.
First you should go with 16" wheels... I did what your doing about 7 years ago,,, tried GY's, Hoosiers and MT's. They all worked but! The MT's have the largest sweet spot of all of them and they were the only ones that did not shake in the burnout which will eat your trans gear set up if you let it happen over and over. For many good reasons, MT owns the fast dragsters, you will see them on most of these cars! Why, cuz they work and are user friendly! To date, both Hoosier and GY are still trying to match the Big and Small Bubbas! Good luck on whatever you choose. |

| Al, the quickest/fastest TD in the country runs on the same tire I do...Hoosier's 34.5/17 |

| I've got the balls and all that matters is what's printed on the time slip. You swap them and I'm game. See you in a few months.  |
