Whats the stock setting from the factory for a tekin 13.5?

Just looking to reduce heat after a 8min main which was 235. I was using Randy Pikes 13.5 setup. the temp outside on Sunday was around 95.

So with all this timing in the esc and motors is it still possible to undergear? I have been fighting what I call a "lag" problem with my car for a couple weeks and can't seem to figure it out. I don't my my exact setup with me right now, but just wanted to see if it's possible to way undergear and still have heat issues? Just off the top of my head:

Car: Tam 416
FDR: 7.41
boost: 43
turbo: 10
start rpm: 29xx
end: 10,500
Ramp: 2
Motor: Ballistic 17.5
Track is large and flowing 180' x 72' I think it is.
With these settings I came off at 203*

You can definitely under-gear (and it will increase your temps). For a larger flowing track I would say you need to be in the low 6's, maybe even high 5's for FDR with a Novak 17.5. Try my changes above along with lowering your FDR.

You didn't mention what your turbo delay and motor timing are. These can be important parts of the equation. In addition to the above, you should experiment with a Ramp of 3, turbo delay between .1 and .3, and running 0-10* of motor timing.

Thanks, the fdr range you suggest is about what everyone else is running, but when I was in that range my car just had no punch what so ever. My delay was .4 and I changed it to .2 and my motor timing is at the first mark past the N, 5*? Like I said I have been fighting this total lack of bottom end and that was why I was running the goofy high FDR. When I ran a setup more like what you suggest it was fast and the temps were down(160-170ish), but it was a dog off the line and anytime I let off throttle. I will try going back to that though and see what I can make happen. Thank's for the help.

I had the same problems for a while. Try the 5,XXX RPM start with a .1 delay for the turbo, ramp 2. See how that feels as far as rip. You've already gone really high on your FDR, so try to keep adding teeth and see how the car reacts. I have found that a higher start RPM with a little bit of motor timing actually has more rip than a lower start RPM and no motor timing.

Thanks, that's kinda the direction i was thinking i needed to go. That was why I bumped the timing on the motor up a little and then dropped the esc timing a bit. I will try going up on the fdr and tweaking the setting as you suggest and see where that gets me. Thanks for the quick input.

Will do man, thanks again. It's supposed to rain here in sunny ohio until friday so, I will try to get out then and do some testing.

same thing here, when running 13.5 i tend to set my motor timing to about 15-20 depending on wether. 20 has way more rip both bottom and top but gets hotter. 25 is like driving modified, but gets way to hot... try running 25 deg on motor timing for half a minute, watch your temps, could get hot but you'd be amazed about the power!!!

Hey Tekin,
My speedo came with some white silicone wire.
Any chance that Tekin would sell the wire separately?
Please?

The fact here is that some Tekin speedos have rubbish brakes. Why? Nobody seems to know.

I have one that stops instantly when moving slowly (which shatters the rotor RPM theory - excuse the pun) and stops in about 3 to 4 metres from 40mph at 34k rpm. I have another that stops instantly when moving slowly, but takes about 7 to 8 metres to stop from full speed. The full speed braking for that speedo is only fixed by turning the reverse on at low power.

Forget all the timing and RPM theories because you've probably got one of the speedos with good brakes straight out of the box.

And if people are locking their tyres up on a high grip track, it's either not as high grip as they think, their car setup is making the car bounce or they're not braking in a straight line so the tyres are trying to steer and brake at the same time.

Oh, and I should add, I buy all my own gear and I really like my Tekins (now at least) so this isn't a bashing by a fan boy of another manufacturer.
I have 2 RS-Pro...I got the first batch and I have never had brakes...So it seems i have duds..Will send back for a check..
Would have been nice to have been told that "sometimes work and sometimes dont work"....A bit like the chinese rubbish..
Bad quality control..as I sent one back for a fix and they sent a refurbished unit back.and yes...No brakes....

That is one thing I can say, my car has more brakes than I know what to do with. Since updating to 203 the car has crazy brakes and with the high FDR when I let out of the throttle at the end of the straight the nose of the car actually dives down like I hit the brakes(I do not hit the brakes). I do not have any drag brake set in either. During 189 days I did have a problem with weak brakes, but they have been good ever since then.

I have noticed that when I run 13.5 with my rs the brakes are good but when I run 10.5 the brakes are weak. Could be because the increase in RPM im not sure

If your car decellerates that much on it's own then something is out.. possibly your fdr is too high
