I don't think we have established the distance in the traps?
I would guess you are using what TrackMate suggests, but that may not be known by all.
if you don't mind, what is the distance between the MPH sensors?
thank you in advance for your kind consideration!

Most of the chassis is original and probably 50 years old.
The arm is a mean green. Only what was mentioned was changed from
stock.
TrackMate suggested 12" as a trap length and that is what I went
with. They claim it is the 1 to 1 measurement.

Saw , Dave's reply. 12" as sugested....... is there an optimum distance for sensors ? I know little about timing systems , would think the closer the better. But suppose there is a minimum distance needed. ........ Peter |

Peter I think the distance is determined by whoever programmed
the system. I imagine they figured out what was needed with their
setup to give actual mph.

yeah, 12" is what the Trik Trak Drag Trax system uses for real 1:1 MPH. and what Track Mate recommends. just making sure.
thank you

I am going to increase the time and add another day. A two day cycle may be to quick. I will post the actual time on Friday, giving 3 days to make a guess.
You are in a 3 way tie so it is interesting.

Going to.say......... 19.8 mph this time. Keep thinking about the t-jet hitting almost 17.

I do not know what got into that car. Must have got a hold of some Nitrous. Best previous was about 14mph for an almost stock T Jet. I have another car that was built similar and used to be the faster of the 2 that is only running in the 10-11 mph range.
I have found that the higher current draw inlines and pancakes really have some weird problems that you do not get with the lower current draw stockers. I will open up a discussion on those after the race.
Next game car coming soon.

Here is the pass the last car made. As you can see in this case despite bigger tires and a low ohm arm it was not faster than the earlier Mustang, just a little quicker in ET. TGM2054 takes a slight lead.  TGM 2054 - 36 Pceng - -35 Mike11142 - 26 Alpink - - 10 Eagle - - 9 |

The last car was a little hard to figure since that stock arm Mustang ran almost the same speed. That car is by no means normal for what it is. From a 50 year old car to one that has only been out for a few weeks. Here is the new Viper chassis with a stock 6 ohm armature, no balancing just one I found in my junk pile. .195 x .450 tires, 8/22 gearing, lexan body. ET which was printed in another post was .5526 which is quicker, not faster, than any other stock arm inline I have.  |

Hey Dave,
Been wondering about results you and others have had with Viper chassis.
One thing noticable from pic is wear marks. Half of one t-mag & leading edge on other. Also grooves in rear of pick-up shoes. Larger diameter tires might help this. Do not know size of front O-rings , but larger ones would lift front slightly. Could result in better (larger) contact patch on shoe. Looks like rear of shoe is lifting front from to much pressure or botteming out.
Just put larger O-rings on G3 that was showing same signs about a week ago. Seems to have worked....... car is quicker out of hole.
Don't know your plans for car (road or drag). But I think all are using tires closer to .460 for their MM/PS cars. Which might all be G cars of some sort.
.......... Peter

Meant to get guess in last night but fell asleep........ I'll say 22.5 mph on Viper (can't forget now).

WHOA, I expected a lot more out of that last car.
Let's see how this one goes, I'll guess 21.95 mph.
