Dave, what kind of mph with those times? Did not realize Super comp was running at 24 volts, I will have to retest them. Running at 20 volts they were running between 23 and 26 MPH. The ceramic magnet car was running 1-2 MPH faster than the Poly magnet chassis, with similar ETs.

My Super Comp cars are running in the .58 -.60 range @ 20v. One is my old PSO rebel which is unchanged from it's old warrior days, and would qualify for comp or PSO right now, I tried Poly magnets in it and they took 3 MPH off of the speed but ET was similar due to a quicker 60'. It still holds my track record for PSO, having run a .54 at 18 volts when it was really flying, for that kind of chassis. The armature in that has at least 200 passes on it. The other is the body Mike did for me with a mean green 5.9 armature, and it has low power Poly magnets, (1400-1500 gauss vs. 1800-1900 at the high end) which worked best and did not kill the trap speed to much, maybe 1 MPH. They are very close in ET with the Rebel being a little more consistent and having a little more trap speed but the Vette takes the early lead while the 57 Chevy plays Catch up.

Nice trophy! I have checked out my Gassers for the upcoming event. Both running just as good as they were at GTS's race. The Camaro edged out the Willy's when I tested them but that is what they did here the last time. I did get a chance to work on Finistauri's Willy's however and it will be a contender. Got my 4 gear stocker running even better, wont touch it anymore I promise. Looking forward to the race. I think this is the largest contingent of racers we ever had from New Zealand, should be a good show. I have a question? Will the race be run on a ladder? Our fastest vs their fastest and so on down the line with total wins deciding who is the winner?

I see, he uses the whole distance from one sensor to another. That will not give a true speed reading however.

Sam I was trying to figure out how it was figuring out the MPH going from the start sensor to the various sensors?? as there usually has to be a speed trap to get MPH. Seems to be working OK and 12.2 MPH is not to bad. I would work on getting the 60' down without losing to much speed. Try different traction magnets and heights along with tires. If you have a magnet tester try and find some better ceramic motor magnets. Nothing to strong or that will kill performance also, especially in a stocker. I put some poly magnets in the old PSO Rebel and it took 3 MPH off the top end. Did cut the 60' down some but not enough to make up for the lost top end. They were some strong poly's however reading in the 1800-1900 range. I think some 12-1400 would have worked well.

Seems legit, I sent mine in.

Looks like you are heading in the right direction. As Al said the speed trap at the end of the TrackMate system is 1 foot.

MPH on my system uses a speed trap at the finish just like the full size tracks use. It is a useful tuning tool. I use the stock AFX rims but I trim them down with a blade to get the wobble out of them. ET however is still the most important item. I have all my cars ready for Jeff's race. My PSO is a little off but still running good enough right now. Will probably try a new set of motor brushes in it. 4GS picked up even more but we will see what happens at the race. I am not touching that again.

This car will run at the Winter Nationals with a different chassis running in the Pancake super comp class.

We do need to make sure the contributions are going to the right place.

No doubt about it Sam the track is the best tuning tool. 1.1 is actually good for a stock 4 gear, it's just that everybody is looking for a little extra. What MPH are you running? That will indicate horsepower and tell you if the car is losing it in the early stages. A stock 4 gear only runs about 10 MPH. If you are doing better than that you are ahead of the curve. In the past couple of months I sold a stock 4 gear, old AFX style, that was running 1.1 and almost 13 MPH with nothing done to it. I did not save it but I should have, it was very smooth. Did not think I had any use for it.

New set of brushes got mine back where it was. Now running .97s @ 14 + MPH again.

OK, I did not see the instructions. We will contribute individually and then indicate Nitro Slots as the Forum.

Unlimited 4G entries for the Winter Nationals. Not to fast but they are both pushing 30 MPH in the low 5s at 20 volts. Unlimited entries 3/21

Gale I have found that the weight will effect ET but not the speed as much. I guess getting the weight moving especially with the lower powered cars shows more in the ET dept. I have not found this to be so true when running a high powered chassis, such as a 2.5 or Unlimited. In some cases there the heavier car was quicker, probably because of better traction.
