As far as temps go.. I would stay under 270F with the engine. The most important thing is to watch the combustion chamber. Take the plug out, and make sure it is not getting too dry. The glowplug should be shiny. Sometimes the engine can run 250, and be too lean, sometimes 300, and still be OK. There are lots of variables that make the engine run hot, or cool. The most certain way to make sure you are running in tune is to see some smoke, and check the glowplug.

I am still running her real rich and it seems my clutch gap became greater than usual while breaking it in so I am sure that had alot to do with it.The hottest run I did with the engine was 220 with the average being 205.And she still had tons of torque even with more gear than I was running in my ninja.Thanks again.

Hi. I use the brake disk on my RRR, and M3. The brake disk is awesome. It is very light, and has zero fade. The brake is also super smooth. I have been using them on my sedan, and 8th scale.

Well today I put a good clutch clutch on the car with the oval restrictor and went to 17/49 21/47.After almost a full gallon I started tunning her up alittle.I am very impressed.Think I am going to end up running a 7mm restrictor for 5 minute runs.This motor has soo much torque.It pulls so hard down the straight it is almost too muchAfter I got her tuned up decent I was running some laps and slammed the throttle hard coming out of a turn just like I normally do and the car spun out.I tryed to get back on the throttle and it spun out again.Got the car back in the pits and to my amazement I broke another rear axle.I have never had this happen before till I put this motor in my car.I broke my first axle last week when I ran two hot tanks and completely snapped one today.I have never had that happen before or seen it before on a mrx.The right rear axle went first then today the left rear axle went.One was a gallon old and the other was the original.I also stripped my front belt and rear belt which ended my day.I guess I am going to have to loosen the clutch alittle and be alittle more careful with my throttle finger.I am amazed by the power this thing has now.Will definitely do more buisiness with you.Thanks for the grin.
