how to build my xmod for drag racing

[65stang]

Hey guys,

I am a first time xmodder (already addicted). My first project is my 1965 mustang. I want to set it up for dragracing. I'm keeping it rearwheel drive, and already added slicks. Upgraded wheel bearings are next on my list. What other parts should be upgraded to increase accelleration? I don't really care about handling or top end, I want it to come off the line hard. Do you guys have any suggestions for a specific motor for me? I also heard that if you take the rear differential apart and remove one of the gears, you can add silly putty, and it will become a spool, or locker. That would be great. Does anyone know more about that?

-Thanks
-Dan

go with AWD it will get her off the line faster but it will lower ur top end speed but u said u werent to worried about tht

Not with the big drag slicks in back. That'll mess up the geartrain. I'd go with a red stage 2 motor with a stock motor mount (metal one is useless). That'll give you a lot more speed, and very good acceleration, but not so much that you'll just spin the tires.

iagree with vipered out because it is a drag engine bacicly

THanks for the help guys. Red stage 2 motor, and I take it I should use the gear with the most teeth? Motor aside, should I upgrade anything else besides the bearings? Someone said "aluminum axle cups" although I don't know exactly what those are or where to find them. Any other drivetrain/suspension components to upgrade?

-Thanks

lithium batteries, Satge 2 motor with the drag (red) gears, Soft Slick tires (in rear) medium springs in rear, if your tires still spin try the soft ones, Unless your tires are still not gripping, dont get the AWD kit. It creates more power to turn all four wheels. yes it helps with the grip off the launch but if your rear tires are doing fine then dont bother, because your losing power as soon as youve left the tree. Also bearings will help with with the friction in the drivetrain and around the wheels.

Red motor, and always match the gear color with the motor color. If you want a lot of top speed but no torque, the blue motor is best, but otherwise, stick with the red combo. I think it gives the best comprmise of the motors (good torque with decent speed, versus either a lot of torque and no speed, or no torque and a ton of speed).

Aluminum axle cups are needed if you do a lithium ion upgrade. You only need a rear set, since you're running drag tires. NEVER USE AWD WITH THE DRAG TIRES. If you end up going with AWD, use 4 equally sized tires, and get front axle cups if you're running lithiums.

I would suggest www.tinyrc.com 's bearings. Buy the shielded one from them, as they are de-greased, and won't get dirt in them.

pretty much what every one else said, red S2 (make sure that you have heatsink, a lot of drag races in a row WILL cook your motor!) Yellow springs, stock tierod, Li-ions if you are going for absolute TOP speed, Metal bearings, and definatly alloy joint cups if you are going to lock your diff (http://www.customxmodsparts.com/gpmsus.html find "ALLOY REAR GEAR BOX JOINT " $9.50, best price yet.) with alloy joint cups, you don't really need AWD with Li-ions, alloy hard to break. tires, go with big in back, and whatever you want in front. the bigger tires make more speed, they do help with the acceleration. (DUH, all real drag racers [excluding imports ] have very large rear tires. [imports were built for gas mileage and engine life, not racing.])

but thats just my 2 cents.

Thx.

I will agree with the red motor.
I brought 9 XMODS to try different combinations.
I sprayed my joints with WD40 and ran the motor bathed in it.
I want to glue the tires but have not found a good glue for it.
I have not tried exotics or lithium yet.

If you remember that huge post on XMW about the heatsink, it isn't really needed. Also, big rear tires should be used with RWD, because it could mess with traction. The reason for a bigger rear tires on rear-drive domestics (and imports) is because they put down slightly more tread on the ground, and they run smaller tires in front because of a combo of wanting it to not interfere with acceleration, and because they put down less tread, making less friction, speeding the car up. That's why the fronts are so skinny.

Try reading. It helps.

Hey guys,

Thanks for all your advice so far. Is the "alloy rear gear box joint" from that webstie the equivalent of a rear locker? Is there a part they sell to make both back wheels turn at all times? (Spool/locker)?

No, they are half of the u-joints. They are much stronger. I wish someone made a locker diff, so you could drive it around normally, than flip something on the diff and lock it.
