OK, some data.
keeping in mind these are the cars that I have run in these classes at the most recent events, untouched with the exception of cleaning pick up shoes and tires and light oiling.
my cars were not very competitive in these classes so this data is going to be eclipsed by those who were faster.
T-jet Pancake stock @ 14 volts
average for 8 passes was 1.2563 ET
lowest two ET's were 1.0550 @ 8.69 MPH and 1.1620 @ 8.52 MPH
highest MPH was 8.69
3 Gear Pancake stock @ 14 volts
average for 12 passes was 1.022 ET
lowest two ET's were 0.8740 @ 10.75 MPH and 0.880 @ 11.25 MPH
highest MPH was 11.25
Inline stock @ 20 volts
average for 22 passes was 0.5066 ET
lowest two ET's were 0.4570 @ 21.71 MPH and 0.4590 @ 21.24 MPH
highest MPH was 21.78 on a 0.4610 ET pass
maybe some others can add their findings.
some have shown data during their races in these class at the 660' mark, which is 1/8 mile, so searching those results will give you better data about cars that are quicker than mine.
I hope this helps at least a little.
looking forward to running this race.
thank you all

Sorry for stirring the pot lol. I just don't want to send in a car I can't use. I was looking at an xtraction car , thinking of how to make whillie bars off the axle , but 2 holes in the chassie definitely would save so much time. I got a couple pictures to what my concern is on two chassis i was wanting to use for the race. One is an ultra g wich the magnet pocket extended past the magnet and was digging in my track rail, so I sanded it even with the magnet. The other is the super lll. The big problem on those are the gears. Most gears including the originals rub the traction magnet pocket. (Not all of them but alot of them). I don't want to be pulling a cheat move or trying to change rules. The kiss method is best. I guess there's two ways of looking at modifications. If my rear axle is wobbly can I put super glue to fix the hole. Kinda funny if you think about it. Sam/Skillet    |

Thanks for posting that info Al it gives the racers something to shoot for.
I have worked on a couple of super IIIs and had similar problems. I took the crown gear out and ground off the outside edge. Your solution is OK but it is up to Al
what he wants to allow. In my opinion that is not a problem. I feel the same way about sanding a little off the magnet pod for ground clearance. I actually don't think
it is slowing your car any as quite a few of my fast cars have rub marks on the traction magnets.
I have a couple of cars that are hitting the traction magnets also but if you put the car on the track and look at the bottom the rails are clearing the magnet.
I think when the car is moving down the track it moves up and down some hitting the
traction magnet. The other solution is larger tires, or larger tires and rims.

Sam, on the Super III and all inlines, you use spacers on the axle to keep the gear from rubbing the chassis.
sanding chassis is not allowed, but, since you are allowed "any gears" consider sanding or filing the back side of the crown gear, away from the teeth, to help get clearance. not too much, you don't want to weaken the gear.
another thing about the gear set up you show .... is that the gear"boss" is supposed to keep the crown gear close to the pinion gear.
so there shouldn't be a lot of contact with the back of the crown gear against the pocket for the traction magnets.
we know that the quality of craftsmanship from Auto World leaves much to be desired and if the bushing (hole) for the armature is too big and allows the armature to move around, there isn't much you can do about that.
you mention trying to make axle holes better .....
you can use a rounded punch or a BB with a hammer to "peen" the hole and make it smaller.
as far as getting them lined up from one side of the chassis to the other, .... probably not going to happen..
bottom line, you might just have to bite the bullet and buy products that are of better quality.
the pictures you show of rubbing of the traction magnet on the rail is caused by using tiny wheels and tires.
for drag cars, you are probably going to want to use larger tires and then the chassis will be well up off the rail.
the roundy round guys use tiny wheels and tires to get lower center of gravity and make the cars handle much better in the curves.
most of those classes don't allow traction magnets so the lower they can get the chassis the better the car will handle.

My track and power supply are comparable to Al's so maybe it will help. Thanks Al for posting. I'm looking forward to tuning for 1/8th mile. The race is creeping up on us so I better get with it. |

Hi AL "Like those Tropies" 😁 How many cars in each class can we run? Can I run Rick DeRosa's "Quiker Tire" silofoam tires? no silifoams in these classes, slip on silicones only. see rules for maximum tire diameter please. 2 cars in each class. Jeff will get you on the list soon. thank you, looking forward to racing everyone's cars |

Hi AL "Like those Tropies" 😁 How many cars in each class can we run? Can I run Rick DeRosa's "Quiker Tire" silofoam tires? Rules can be found on Page 1 of this thread. There are also preferred body types posted under chassis rules. But that is up to the Racemaster. You are on the list in all classes. Welcome to the race. |
