The 353 was great. The engine has tons of torque, and fine top speed. I was using the Kyosho RRR Evo with pinions of 17/23, spurs of 60/55. I felt like the engine could have pulled a 24 tooth 2nd gear. I used the Novarossi 2630 pipe with medium header. I used 30% Rocket Science fuel, and added .2mm shims under the head. Runtime was also not a problem with the engine. I was able to qualify in second position in the Sedan A main at 301 Raceway this weekend using the engine. I actually had the lead for a while, until I stripped first gear. The longer I run the engine the faster it gets. So far I have over 1 gallon through the engine, and it is still getting faster.
Oh by the way...301 Raceway is now my favorite racetrack. This place is one of the nicest racing facilities in the USA. If not the best. The layout is extremely fast, smooth, and fun for sedan, and 1/8th scale. Great traction, wide lanes, and some very fast racers make for some very intense, and fast racing. I can't wait for the Capital Classic in June!

Congratulations to Vincent Jackson for chalking up another win for Murnan Modified Motors, and Mugen . Vincent dominated the 1/8th scale A main from start to finish with the Murnan Modified Ninja R01A powering his Mugen MRX4-R.

Stay tuned to the website for more details of the race!

0.2mm shims??? Isn't it normally 0.1 for 30%?

Hey Uriah. I have one of your Ninja .12's with the skyline pipe. I broke it in on a bench per Swauger's method. I raced it for the first time this weekend. I was trying to keep it around 270 and when I kept it in that range, it ran great and got good mileage. I decided to experiment a little and leaned it a little more (like 1 clock position) and the motor went ballistic! The power was definitely on another level and I was thinking, man this motor is sick! Then, I pulled into the pits and the temp was reading 300. I felt that was too hot so I took it a little richer and that magic power I felt was gone. I take my temp readings with a typical temp gun pointing down on the top of the head at the glow plug. I was running a #5 plug at the time.

I'm wondering if i'll be able to get that power out of it again when it is broken in a little more? Or was that just a little too lean. Do you think it was okay and that the temp reading I was getting was just higher than actual? Any help would be great. Thanks.

(I was running Mugen 30% and I did put another .10mm shim on the head)

Hi. The most important thing is not the temperature. I have some engines that run that hot, and it is OK. The best way to make sure you are within the normal operating limits is to check the glowplug after each run. Make sure the glowplug does not look dry. If it is dry, the engine is too lean. The bottom of the plug should have a coat of oil on it, or at least be shiny, not dull. Make sure the glowplug coil is not deformed. I would use a # 6, or 7 plug. The # 5 is pretty hot!

Thanks Paolo. I wish I could have finished better, but that's racing sometimes. I must say DJ Apollaro was ultra fast on this track. Congratulations to you DJ on your TQ in sedan. I have a feeling team Serpent will be very strong at this event. Ashton, and DJ were both looking very good on the track. You will like it here.

Thanks..
Yes, I tested the engine in my RRR. No problems. In PR the engine will probably run hotter than my readings, just keep an eye on your glowplugs.
