done with the first diff now. Feels (a bit) tighter than the rear one (<- without good shimming), but without the extrem wobble at the outdrives. I used 0.1 out and 0.4 in at one side and 0.3 out + 0.4 in at the other side. I'll rebuild the rear diff tomorrow.

Cain,

You are a fkn saint. Your patience is rock steady... I was flinching just reading it. :mad:

It looks like rain is coming in, my race season might be coming to an end this weekend. :( Time to decide if i'm spending alot of money in gas to drive up to Wild Choke's place; TRCR, or go carpet touring racing for the winter. :confused:

How far is the drive up there to that track SC Shaun?

What are peoples thoughts on compounds they are using and tires for carpet with there sc10 4x4?

Well...

I have seen a lot of "factory" drivers say "my car wanders, I'm putting toe out into it" and it work. It makes the car track straight because it induces scrub, and the extra toe out makes the car tun in a little crisper. It also can induce a mid corner push because of the ackerman it induces.

Because of the servo's self centering function, toe in (which in a "street" car causes the car to go straight by the same sort of tire scrub) seems like it makes the car have hyper steering center off.

On an unrelated note, after running sedans indoor on carpet for a week, I now realize what a pile of shit 4wd short course is to drive by comparison.

I think you have them mixed up there.

Toe-in in the rear will lock the rear in, and induce scrub. Toe-out in the front will give you sharper turn in.

100%.
Driving onroad teaches you how to tune and really takes a fine touch to go fast. When I raced on & offroad years ago, if I raced onroad on a Saturday and offroad on Sunday.. I killed it on Sunday.

Agreed, but it makes a difference if you have a servo self centering or the driver has to bring it back.

BTW, all toe induces scrub.

Everyone should try racing sedans for the first time in 10 years at a big indoor race, with no pit man, zero testing, all controled practice, two new cars that never so much as turned a wheel, and oh yeah, get all your support gear (except for your transmitter) stolen a month before the race!

It's not for the brave of heart, but I had a wonderful time at the IIC and am really glad I did it.

Going from toe out to a zero toe setup calmed down my truck on straights and took te twichiness out

Frankly, that seems completely legit.

I used to run carpet TC and offroad. Onroad actually messed me up for off road. On road cars are planted, and can be pushed pretty hard. Offroad I would start to over drive my car and lose time. But I miss onroad, I dont think anyone does it here. TC used to be huge, I guess it died.

I'd love to get into on-road, but there's not much of a scene here. I think it'd make me a better driver, as I would have to focus on being smooth while driving at or close to the limit.

I got to watch Hartson run this past weekend, and his truck looked really good (as it should of course). It looked nose-heavy, and the back did rotate coming into the sweeper, but it was VERY controlled. With some quality time, this truck is very competetive. Granted a Losi took the win, but Olson (Losi/MIP) was on a whole different level.

+ YouTube Video

Thanks for the heads up.

Sedans are on a whole different level. Used to run sedan heavily in CT in the early 2000s. Back when the whole 19T class was a big deal and xray had just come out with there first vehicle.

Ok, not sure what to do here, but my SC10 4x4 is just plain slow, really slow, as in slowest short course on the track at the Southern Nats.......by a long shot.....Here is my setep:

- Exotek aluminum mid-chassis to reduce flex
- Exotek aluminum front diff lock replacing inner slipper pad
- Front slipper/clicker lock (CA'd together)
- FT slipper basket
- Tekin Pro4 4600 4pole with Castle MMP with no timing

I run between 11t - 13t pinion depening on track size. Temps normally around 160-165 after 8min. Nol distinguishable noise, grinding, etc. I took the belt off and both front and rear wheels seem to spin pretty free. Belt on, not so free (Pinion removed).

Not sure what to do now....I am told I jave to much motor, yet have the slowest truck on the track. Stumped and not sure what to do now......

where are you slow on the track?

Going down the straight, where are you topping out?

People have reported on this thread they get more power when switching from the MMP to say the Tekin RX8. Me personally plenty of power with the Speed Passion GT2.0 Pro.
