I TO have found a " hot " arm. ,found it in a lot of old cars a buddy at work got from a clean out. afx non m/t, looked bone stock, 5.2 ohm,dark green wire , red tip arm in it

Yes the green wire red tip arms are more common. I have seen quite a few of them. They run as good as the mean green arms.

I cannot get these cars to be consistent. They will vary as much as .2 over a period of time. Cleaning helps but not always. This is typical for pancake style chassis but it seems worse at lower voltages. The lower voltages exaggerate everything.

This is typical for pancake style chassis but it seems worse at lower voltages. I'm curious Dave. What length of a "period of time" are you talking about? I've been warming mine up at about 9v for about 40 to 60 seconds and they have only been varying .020 at the most.

I am talking about day to day or even days. I warm them up for about 5-10 seconds. I do have to say the .2 is on the extreme end. Having your cars that consistent is very good. I cannot get that from one run to the next running them back to back. Even there I get about a .02 - .06 variation. MPH will vary some to, about .5 MPH from run to run.

I'll do some more runs and keep better track. I'll write down before warmup and after, I'll let you know the variance and do a post. My cars are naturally slow anyway so maybe that's why .

Thanks I will do a similar test and let you know the results since the above statements I made are off the top of my head which can be flat at times.

Three of these cars are running red tip 14 ohm arms, one has one of the newer AW 14 ohm arms. I do not balance any of these as I have not seen any benefit from that in the past. All are within .1 of each other.

From L to R; the Nova & Chevelle are ThunderJets and the 2 Camaros are AFX Magna Traction. Well I was whacky about what I told you earlier, concerning the times and consistency . Each car was ran twice in each lane without warmup. 3 hours later, same routine only warmed up first for approximately 60 seconds @ 9v. Nova before warmup, .334 difference, after warmup, .086 difference. Chevelle before @ .181 difference, after @ .175 diff. White Camaro before @ .267 diff, after @ .109 diff. Blue Camaro before @ .265 diff, after @ .057 diff. There is a .357 second difference between the best Tjet time and a faster, best AFX time. Now this probably doesn't have much real world meaning but it was my observances on my track with my cars. Don't know where I came up with that .02 difference , that's plain whacky!

I don't know why my T jets and AFX stockers are running almost identical times but that's what they are doing. Going to test right now with no warm up and then warm up for 10-15 seconds each, then post the difference. Cars have sat about a day or two. First run cold with no warm up then with a 15 second warm up before each run. Both T jets slowed after warm up The 67 was down by .08 with an increase in MPH of .3 and the 69 Camaro only lost .01 with a loss in MPH of .8. After warmup the AFX green 57 Chevy picked up .04 with a MPH pickup of .6 while the Challenger lost about .02 with a MPH drop of .2. I cleaned the two AFX cars which resulted in an ET drop of .06 on the 57 with a .8 MPH pickup. The Challenger picked up the most with a huge .2 pickup and a 2.5 MPH improvement. The Challenger had started to run poorly for some reason? The difference between all the times run were separated by about .29 and 3.2 MPH which includes the cleaning improvements. Just wanted to add that my fastest T jet time vs AFX was only .01 quicker for the AFX. Before I changed bodies on the T jet it had the fastest time by .03. Yes for some reason or other the body slowed the cars best time by about .05.

I liking what I'm hearing on the ET's and testing. This is something else that will affect cars running at the lower voltages.....the track. If it's not clean or there's bumps at the joiners....anything like that will also affect how smoothly they make the run. I have to do more track prep and cleaning when running the stockers. There have been a few builders in the past that have built fast and consistent stockers so it can be done. I'm sure the cars are going to run just fine. The cars that GTS and Dave have shown are sweet and I am looking forward to this race!!

**ATTENTION ATTENTION**
The King of the Streets at Bear Creek Dragway is less than a month away and shipping day is even less than that! Don't wait till the last minute to get the cars built.....time is ticking past. It's going to be a great event with some cool cars that we don't get to see that often. So.........if you are already in the game, get the cars built. If you are not, there's still plenty of time to get entered and get the cars to North Texas. Everybody has some stockers!! We already have a full field of cars but there is always room for more!! Cars need to be here no later than Thursday March 26!
It's all going down March 27 - 29, 2020

Classis are filling up nicely. Still plenty of time to get some cars ready. Mine are still erratic but ready to go. Am letting them sit for several days then I am going to check them again and see how they do after sitting for awhile. Some times they come out screaming and other times they lay down and go to sleep.
