after putting in the sirio power clutch, yesterday i went down the track to see how it performs comparing to the previous clutch system.
its been a week since last i ran the motor. (i did not put any afterun oil or whatever) , put the car on the starter box, crank it once, twice and then it kick in for awhile and stall. increase the idle , crank it and it kick in again, and let it warm up . place the car onto the track ,run a few laps, i open the high needle ( 3 minutes) , run another few laps .
as for the clutch performance i can feel a big difference esp. more 'punch' exiting the corner. for the top speed sure looks fast but i can say how fast coz i was alone with no other car to spare with. anyway from the sound it was freaking fast

last time at my lhs around 300 - 350 usd.
anyway yesterday i went to a bigger track to practice and test a few setups. and it feels more aggresive with this power clutch. and yes this time there were few other cars around to compete, there was even a S960 . there was much power and grunts at the bottom and also when the 2nd speed kicks in it was totally insane this engine and the power clutch combo do really really made me excited . still can be fine tune can't wait to race it as soon as possible. after finished the day , i dissamble the engine . the top of piston was a bit wet and shiny and light brown colour. the glow plug was sligtly on the dry side. iwas using 16% o'donnel . there were no abrasion inside the back plate.

hi all,
need some advice, how much fuel do i need to break in this engine?
i've just break this engine in for 1.25 liter on a break in bench with fan,nova c6 plug, temp was 55-60'C.lean down HSN 3/4 turn on my last 0.25 liter, still very tight about 3/4 length on the way TDC with metal stretching sound. this scares me a lot

just an update:
this engine is fast!! a-lot of fuel went in for the breaking in. 1.5L.. but its all worth it. used a nova #6 plug and HEC pipe. nice bottom and mid end, slightly smooth on the upper end. went on the rich side but still last about 4mins/tank. highly recommended to all on a low budget and a need for speed

hi there, u can try HEC TURBO pipe set without much problem. i matched it with 3SCT tuned, JP-P3L and recently GRP MRT. all compatible, power and runtime wasnt an issue for USD$45 at my LHS in malaysia.
hope this help

i just got the promo kit..
for what % nitro is the engine shimed at out of the box?
i removed the head to have a look at the head button.. there was one silver shim and one copper shim.. anybody knows the thicknesses of these?
there's an extra copper shim with the kit.. any body knows the thickness of this as well?
thanks in advance....

thanks ivan...
I'm assuming the engine is shimmed for 16% out of the box.
since i run 20% i added the copper shim that came with the kit and hopefully that would be enough..
