For those of you that do not like the power band higher think about this:

In full scale racing the goal is always to raise the peak power numbers to a higher number and a higher rpm range, than you put more gear in and the results is more power to the tires, even if the power is the same. It is simple math, same power, more gear, more power to tires. That is why F1 runs 18,000 to 20,000 rpm and why NASCAR engines now have peak power at 8500 rpm when it was 7500 just a few years ago. In NASCAR it is so important that they put a gear rule in place to keep the rpm's in check.

Take the higher rpm's add gear and go faster, it works!

remember, adding gear will make the bottom suffer, which a bunch of people here are saying they are experiencing.

i don't have the motor and i haven't used it myself. but a fellow racer was running one last week and i don't see the bottom suffering at all. we have a very technical track where it requires a lot of torque out of the corners (slow turns so acceleration is a must). his car takes off pretty quick and quicker than my OS. he was using a VR12Plus pipe.

I think we are saying the same thing, adding gear in my example means a lower gear (higher number). Different forms of racing use different terms for talking gear ratio. In my world of full size racing when we say add gear or shorter gear means bigger number for ratio. Taller gear is smaller number.

Now I am confused......LOL

Hi Mike,

I can't get it for that price. Your help would be appreciated.

While designing the engine 2 cooling solutions were tested for the cylinder head, one with two different parts, button head+cooling head, and one with only one part, engine head with cooling fins in one piece.

The one piece design has a better cooling capability and could be usefull in extreme heat conditions. That is why we decided to offer it as an optional. However it is not required 99.99% of the time, unless maybe you live in the desert or something like that

ORI81308 is the original part.

Where in the US or online can you buy the Wasp Rev 12 and CRF pipes ?

My LHS still has the motors on backorder from Horizon.

The last place that had the motors in the US was HRP and my LHS got the last one for a special order. The pipes are not available yet.

Has any testing been done with the Kyosho lightweight flywheel and clutch bell? Also, what is the best application of the weights? Are all nine intended to be used or are there instances when you would only use none, one or two? Does the parts ship with some type of instruction sheet? If so, could we see a copy.

I think this is the first time I've heard of the V6 CRF Clutch. Is this applicable to on-road vehicles? The way it's written up, one might get the impression that it's for off-road vehicles.

Thanks!

rmd,

I think that the testing was made with the original flywheel and clutch bell but I'm not sure. The clutch was designed with all weights fitted at all times. We will have some form of instructions for the clutch with as many info as possible.

Josh and the rest of the team will be using the CRF clutch parts at the nationals this week-end.

This is what Josh wrote in his report about clutch testing : "Next, I tested with the clutch parts from Fabrice. I started with the settings as you said and it was quite good. I only made a small adjustment (clutch nut to 1.6mm) and the clutch was perfect!! Good power, nice to drive and extremely consistant!!"

Important is also the shoe/clutch bell clearance which has to be 0,5 - 0,6 mm

The CRF V6 clutch is originally meant for off-road cars (1/8th and Monster Trucks). It was also designed by the guy that designed the motor, he felt that he had to improve the clutch designs that existed because he was not satisfied with them He runs one on the Wasp .12 that is fitted to his 1/8 scale buggy
