Thanks a lot, Stefan
I would suggest the Murnan Modified 35+21, or the MM Flash. The MMRBC9 is very similar to the 35+21. It also runs very good. They are all very fast. I have not dyno tested the TQ yet. Maybe someone who has had both can chime in.

There was a river running through the yard, but no flooding inside here. Two miles down the road was under water for a few days though.

The Cordoba does have a smaller crankpin. Just about .25mm. Just enough so you have to buy the Cordoba rod. The 359 had an even smaller crankpin than the Cordoba. I don't have one here, but I am pretty sure the 359 rod was .25mm smaller than the Cordoba rod.

That's what I thought.

5mm for most novas.

4.75 for Cordoba

4.5 for 359.

Hi Uriah,

what's going on? well our season hasn't started yet but since the weather is getting nicer and colder, we had a fun Offroad race last friday, it also served to test a new race managment system for the upcoming season.

All the Pro guys attened the race with different car brands and engines, the track was very technical and tight with sandy surface, i changed few things on my MP9 and tuned my Murnan Modified SIIM to 220F (enough for such a tight track) happy to let you know that i TQed the quals by hitting the 17 laps mark (the only 17 laps in the Qual) and winning the Amain with no problems

thanks for you great Modification, God bless Uriah

cheers

Ali

@Grinder

Oh, you got me on this one... I havn't even recognized this until yet! Thanks for the information.


By the way: What is your experience with Novarossi glow plugs? I am getting more and more issues with them. They either dont glow very well right from the beginning or die after a long run. Could you please recommend any alternatives? Direct replacements without the need of buying a new underhead?

Thanks again, Stefan

Look at any other form of motor racing and show me where "stock" is actually "stock". Besides, ROAR makes the rules so why don't you complain to them instead of on this thread? Seems to be personally motivated.

With all due respect I wouldn't waste my time making it personal. I didn't consider it complaining either, yet I just stated how I felt and if you or anyone else doesn't like it oh well get over it... To me it seems like much attention is on modified engines than the actual skill of the driver itself to my interpretation and I've been in the hobby for sometime now. I feel a motor alone no matter how many times you buzz it with a electric vibrator it won't win a race if you can't drive it around a track worth a damn.

Well, if you bothered to read through this thread (which I doubt you did) you would see that Murnan modifies to increase mileage, make the motor easier to tune, ect. You can be the best driver in the world but if guys are making 5.5 min. and you're only making 4.5, you will lose.
Also, if you raced somewhere that considers this a sport instead of a hobby, you would understand it. There really is no point putting a modified motor in your car if you're just going to bash it around a parking lot with the local kids.

hello there,

what about having both of them?? driving skills and a rocket to insure your win? in any motorsport, RC, real drag racing or bikes, you won't be able to compete in higher levels unless you run modified engines,

i started running modified engines a year ago (Murnan Modified) and i dont think ill ever run a stock engine again, why run stock when you can get more power down the straight line, more fuel and a motor that's easier to tune??

cheers

Ali

I may be wrong, but to me (I have stock 35+21 and MM 35+21's for my MRX-4X) that the top speed is a little better, but the pull out of the corners is much better. To use this you have to drive better and have a good set up in the car. So in short to get the most of of the motor, you have to be a good driver. I also agree that they are easy to tune and hold it very well.
