We did not have chance to really test the engine due to rain so we were very conservative on tuning and gearing. Next race will be Xceed cup in Shanghai so we will be better prepared.

here are some photos. over 100 entries

Ronald is first time with Nitro and races without any practice, so not fair to compare

Hi,

After replacing the conrod on Murnan RBM3 .12 engine.

Have been told that I should use either a Rossi 7601 or 7604 does anyone know if this is correct and which one I should use?

Cheers

The Nova 07601 is the correct rod

Use 07601. I have used 07604, but it requires some mods to work properly in the M3. 07601 is a great rod.

There is a picture of a dyno on the web site.

Any dyno charts for the .21 on road motors?

before / after.

Thanks.

Sure. Here is a graph of a stock 35+21 vs MM35+21. On the same graph is a stock Flash, vs MM Flash. These were not the newer Flash Special.

I don't know about his modded ones but a stock flash has a higher exhaust timing than any other stock motor I've seen. That would be where the top end comes from. Me, I like how the modded 35+21 spanks the flash all over the place from 20k to about 34k. I bet that even with the top end advantage on the Flash that the 35+21 still has more area under the curve.

Which reminds me, I have been wanting to know if it's possible to put into your dyno program a way to actually calculate the area under the curve? I think that would be a VERY useful number to know when doing comparisons.

After looking at the chart posted, I to cant see a reason to use a flash, unless the new ones are different.

I have looked at countless dyno charts(big cars) for real cars over the last 6 years and the power band on the 35+21 is outstanding vs the flash. Most of the time the car is going to be using that mid rang around the track.

Grinder do you think the new flash motors match the 35+21's mid range?

Also can you tell us what pipe and header was used for the dyno pulls on those motors?

Thanks for all the info

there is a big difference in the midrange!
