Default Fixed Diff - Foam Tire

Hi,

I just got back from the ROAR carpet nats (foam tire) race where I brought both the evo and the 415. I did terrible but it was a good test session for the 415 on foam. I made a front diff from HPI Pro2 outdrives and it worked well. I also made a fixed center pully, based on some ideas from Dan and Troy.

To make the center pully you need two set screw based pullys. you will need to sand down the alloy spur adapter so that the side that would normally butt up against the center one-way, is sanded down so that the alloy is flush with the spur gear. This provides the required room on the shaft to accomodate the set screw based pully. You will also need to sand down a flat spot on the pully shaft so that the set screw on the new pully has a point to grab onto. It fits perfectly.

I did find however that with the center pully locked and the front diff on the car, that the car tended to hop under acceleration. This hopping was reduced by running the center one-way with the front diff. In the end I think this hopping was caused by the front diff creating a vibration.

The mistake I made at the race was splitting the limited practice time and the qualifiers between the two cars, so I did not maximize the setup on either car. Having said that, the 415 on average was 3 tenths quicker per lap then the evo. I think this is mainly due to the stiffer chassis. My car had a huge push in the main so I was about 4 tenths a lap slower in my main than during my qualifiers. oh well.

My Setup for the 415 was as follows. It worked well with 57 to 58mm tires. But in the main I ran a 55mm tire which is why I think it pushed so much. D'oh!

Front:

Springs : Assoc Purple
Anti-dive : about neg 3 degrees (spacers under rear hinge pin block)
Caster : 8 degree caster -> producing about 5 degrees with the anti-dive.
Sway bar : blue
Shock position : outer hole on arm and shock tower.
uptravel : betwen 0.5 and 1.0 mm
Tire : Speedmind Multi-Compound (52/35) (28 mm wide, cut to 57.5mm). Glued outer verticle edge.
Ackerman : forward hole on steering knuckle
Upper Links : stock spacers on upper deck. Used outer hole in the c-hub (Cut off the verticle tab)...to allow for a longer upper link.
Front hinge pin block : D block
Rear hinge pin block : A block

Rear:
Springs : Assoc Purple
Shock Position : Outer hole on arm and shock tower
uptravel : betwen 0.5 and 1.0 mm
Sway bar : none
Anti-squat : a .07 mm spacer under the front hinge pin block
Tire : Speedmind 35 (28mm wide, cut to 57.5mm). Glued outer verticle edge.
Front hinge pin block : D block
Rear hinge pin block : A block
Rear Upright : 1 degree alloy.
Upper Links : Stock spacers on upper deck. Inner most hole on the rear upright (ie. short rear link).

Dude, I haven't even driven anything since I left! I've been busy at work and the beautiful tracks are no good when raining!!! The TCS is not until 4/25 so I haven't even built my car but got some tips from difuser and am looking forward to it.

SoCal is still the best!

Default Spur and Pinion

Could some help with a couple of questions I have.

1. What Spur gear comes with the 415 (size and pitch)
2. What size pinion gear come in the kit
3. What is the internal gear ratio

I am still waiting for my kit but need to start working on some setups.

Cheers
Paul Griffin

Also People who dont know the gear that comes with the car is a 64 Pitch Metric Not a normal 64 pitch. They look like they fit but there a little off. So buy a real 64p

I run
Motor: Monster Stock
Gear: KM 104t 64p[after market gear]
34 Pinion
