Gas rat: Your probably under geared. Im running a 15 on an outdoor track. Temps come off at 140. Under-gearing can produce heat also.

Running rx8 with tekin 4600 started with a 15 tooth ran 33800 rpm and around 155 F. Switched to a 16 tooth added fins using thermal compound rpm dropped to 29000 rpm temps stayed about the same and I dropped 1 to 2 sec off my time. I am not running any current limiter and 10 timing. Running stock setup except Proline suburbs on hard packed Ga red clay. I need to pick up about 1.5 sec somewhere to keep up with the big boys and young kids.

That is pretty agressive gearing for that motor. Dropping down the CL to 80% really will not hurt performance but will help with motor temps as it gets rid of amp spikes that just translate into motor heat. Going back down to 15 with a little current limiter to limit wheel spin may be the ticket for you. Going up in gearing I am sure calmed down the bottom end on that motor for you to help make it more controllable. You can do this to an extent with CL settings as well and not have to run so agressive on the gearing.

i saw most of the people/team racer only using the lower holes for all the camber links............just wonder what is the difference if using the upper holes

Raising the fronts will take away low speed steering and add on power steering. Most 4wd push into a corner.

Rear upper holes will keep the rear end flatter and produce more fwd traction but less side bite. Again 4wd's tend to pull hard with there front tires and can be a little loose in the rear so we like the extra camber gain.

You know, its funny, was just about to ask about this.

Im using ryans new setup (553), like it a lot, just a few minor adjustments.

Im trying to get rid of that slight push going into a turn. I have moved the camber link up (1b). Im thinking about removing my sway, wondering how much of an effect that will have.

Any other suggestions? Just would like it to rotate around 180/90 degree turns a little better.

Thinking of trying 7k in the center diff (573) or run 2k in the rear (552).

Thicker center diff will take away some off power steering. I would try a softer front spring or a little more front camber first.

Thanks for the info casper.

Which is a bigger change? Want to go smallest first to see what it does and adjust from there.

In order what would you try first?

Will removing the front sway be more or less of a change than the 2 you mentioned?

The easiest change would be to add a little front camber. You can take off one of the verticle risers to disable the front sway bar without actually taking it off. Changing springs means resetting ride hieght.

I have not tried no front sway bar yet so not sure exactly how big a change that is on this truck.

I would try the camber change first just because it is so easy to do then try the springs and then the sway bar but that is me. Are you still running the stock sway bars?

No, im running the exact setup from Ryan (the newer one). 2.0 in the front, 1.8 in the rear. I believe the front is 1.8 and the rear is 2.0 stock correct?

Thanks again casper, going to give this a try tomorrow.

Default pro4 or 550?

hi guys. my scte is on its way from 1hobbies. do you guys prefer the tekin pro4 motors or the tekin 550 sc motors? ill be running on a very large outdoor loamy track. if its been asked already, can you point me in the direction for the posts.

also has anyone tried any other esc instead of the rx8? im looking at the hobbywing. i run the xerun's in my touring cars and wanted to keep the electrics in the same family.

thanks.

Yes we are running opposite stock on sway bars. Just checking to make sure we are on the same page. Might want to try disconnecting the sway bar to see the extreme and if that is too agressive you can go down on the front sway bar. Swaybars as a general rule of thumb take away traction from the end you install it.

For a large track I would stay with the Pro-4 motors. They produce just a little more power then the 550's and save some weight in the truck. 550 motors are great and tend to have a little smoother power band. Still great overall power but not quite as much bottom and are about 2.3 oz heavier. I highly recommend the RX8. Great reliable speedo that produces great power.
