Hi, i have a friend with a little problem on his ZX12 ... he finished the break inn period on a TM G4 EVO car ...

The thing is that the engine throw a lot of smoke with good temps n the track, a lot of power BUT he is burning glow plugs as hell !! ... he went over 3 plugs on 5 hours of practice time ... and dont know what to do ... he have the stock shim setup so he asked me to post here the problem and see your opinions about a solution ...

thanks,

How many shims is he using? What % of nitro is he using? What # of plug is he using? Usually when you burn a plug is because either the engine is too hot or too cold. On this thread I have read that you cant use the smoke of the engine as an indicator of setting since its very different from other brands of engine.

I think there is info from factory guy not to use oil content higher than 11%.
We have terrible experience using 12% oil content.
After using 11%, everything became alot better.

Use Mega or Picco plug, slighty deeper than nova's.

With new plug, rev up couple of time and unplug it and watch the plug coil.
If the coil pull up(to direction when installed), add shim(&/or use colder plug) if it pull down (great !!) use coldest plug.
Above is just basic thing, anything other than that is still possible.
Good Luck.

for my zx12...

what pipe would you guys recommend for long open fast track? (brendale where 2006 200mm worlds are).

i used the one which comes with the powerpack the last time i was at a similar track but the motor had awesome torque and accelloration out of corners but it lacked for top end speed (moorebank sydney).

also has anyone tryed the new conical header? ifso what do you think over the std header.

Thanks!

Will be interested in options as have already entered for the pre-worlds. If you know anyone with a 710 racing there, get them to flick me a PM.

my mate who's traveling up with us from our club races the 710, he also just bought the zx12 motor - but i'm not sure if he will be using it at the qld titles or not. also i'm not sure if he visits rctech or not, i'll check with him next i see him.

Has anyone tried the ZX-12 with a Skyline Pipe? Im using mine with it and I havent seen any problems yet. Im using 30% O'donnel, #7 plug and (2) 0.1 shims. Should I invest $80 for a Mega Picco Pipe set for better performance?

This is after about 6 litres of fuel and roughly 7~8 hours of racing, not including run in time - which was done per manual.

fuel used throughout was 16% with 12% oil (50/50 castor/synth).

Hey dynamite did this happen on the weekend at the QLD titles. Before it dropped the rod how did you find to engine on the Brendale track. Didn't take much notice of the tourers this year. But I did hear a few people saying they where lacking HP. They where using other manufacturers, would just like to know what you thought.

Cheers

Graeme

hey graeme,

yes it popped at brendale in the 3rd qualifyer, right after i was starting to get on top of setup too. i found the performance to be quite ample for the price of the motor which lets be honest was worth a quatre to half the price of other cars i was racing against.

i was lucky enough to have a friend lend me a jp fx, the one with ceramic bearings and a mugen pipe - with which i was still lapping roughly the same.

i'm hooked on the brendale track now, that is a great setup they have up there! the 2006 200mm worlds are going to be hard to beat facility/track wise in the future for sure.

regards,

cory

Yeah Dynamite it's a great facility. It's even better when you live only 5 mins away and work only about 2 mins away. Been racing at the club now for 3.5 years and honestly there's no other track like in Brisbane. Glad you guys had a good time and might see you in Feb 2006.
