Hey all.

Im a bit confused regarding more speed from the Tekin. Im going pretty fast as is with help from Local tekin drivers but on the weekend i wanted to get a bit more speed and couldn't find it. My motor was coming off at 65c so I geared up but when i did so i lost punch down low which cost me time over 5 minutes. Im talking a jump from 7.6 fdr to 6.8 fdr I started with a 21tooth pinion and got faster up to a 24 tooth but a 25 and 26 were slower. It was suggested i try something like a 8.4 ratio to really get the speedy working more than the motor but i didn't. Sorry Ant

Will changing the start and end rpm help this issue?
What can i do to get the extra top speed the gearing brings without sacrificing bottom end grunt?

Cheers Benzaah.

Had a meeting yesterday and was suprised that I was outpaced top and bottom end by the new GM 120 Speedo.

I was racing 10.5 and would get caught up on the straight (40m) and the GM had more rip out of the corners.

Any help would be grateful these are my settings :-

LRP X12 fully retarded (4 dot insert)
Boost 50
Turbo 15
T. Delay 0.1
Ramp Rate 2
Start RPM 5443
End RPM 20000
Throttle Profile 5
No Drag Brake
FDR 7.75

Temp after 5min run 160 F

It looks a really aggressive set up but had to be done to keep up. Incidently brakes were very poor. (On 100%)

Thanks
Jamie

to much timing gives less power and top speed
dont go over 65deg
keep it between 60 an 65

Try 0deg insert on motor
40 timing

Putting the motor back to 'standard' timing might give you better results with the taller gearing.

If you want a bit more 'snap' you could try increasing the start rpm to 10,000rpm or so.

i think your motor makes way too much revs. revving up the motor takes a lot of energy too. thats what i experienced driving 10.5T indoors with a high gearing like 9.5. when i lowered it to about 6 it was way faster, also more punchy...
This is my setup for a Epic Nemesis 13.5T maybe comparable...
gearing: 6.0
motor timing: 15
boost: 45
start/end: 5500 / 20.000
turbo: max
turbo delay: 0.2
Turbo ramp: 3.0
brake strength:100 on esc, 65 op remote
Temps: 75C

When i wanted more start punch or infield punch i would add motor timing however this makes the motor too hot, but is very powerful!
gearing down gets the motor more in its designed power range. most of these spec motors just dont like to make this much revs.
with this setup i raced yesterday at our local club race, finished 3rd. 2 guys were running GM ESC's but i had more power in the infield as well as on the straight. however they wouldn't get their motor above 60C.
also brakes were so powerfull i had to put the remoteback to 65,to get a controllable stop.

Hi people i'm looking for some advice with the Tekin RS Pro for mod motors. I'm hearing conflicting stories as to how the set up goes, eg do we keep it set up sensored or do we set it up on dual. I've been running this speedo for 2 months and it is absolutely awesome in 10.5 and 13.5 but with our outdoor season starting i'll be running Mod 5.5t.
Thanks in advance for all your help with this and sorry if the questions trivial.
Scotty

Default 10.5 set up with LRP X!2

Hi guys - Thanks for your help.

If I go to the standard timing on the motor this is even more timing - Is this definitely what you mean? I understand about lowering the boost to 40

Basically the main advice is to reduce the timing by lowering the boost and gear from 7.75 to say 6.75?

Moving the Start RPM to say 10,000 will give more punch before the Boost kicks in ?

So have I understood your advice correctly?

Thanks
Jamie

The x12's seem to have a lot of torque, so you should be able to use the gearing to get at that power.

I have found that if I wanted to calm the car down coming out of corners (particularly on cold tarmac) I reduced the start rpm.
I don't know how big your track is but in our 180deg corners the cars are still doing 14mph, which is something like 11,000rpm. The closer I started the rpm to this value the more aggressive it was out of the corners.

I wouldn't jump that far in the gearing in one go, try half that, say 7.25 and check temps.

It's finding that sweet spot that takes the time

i'm running std timing on the motor
gearing 7.6
boost 40-45
start 9xxx, end 30xxx
turbo 10-15
delay 0.4
ramp 2

i never see below 8000rpm on the data logger even on hairpins

the X12 doesn't like to rev, it just gets hotter and hotter. i've tried running gearing all the way up to 9.5 but somehwere between 7-8 seems to be the sweet spot depending on the track. BTW even geared at 7.6 i see RPM around 55,000 on the data logger at 9.5 it's ummm to the moon! The car is almost as fast as my 4.5t motor just without the punch.
