Rainer,
a bad ass engine for a small track is the mugen x12 modified by murnan. he has a thread on the main forum. i have several (about 5 of the X12 by JP) and the murnan mod is better.

his link is in my signature. i am not sponsored by him, i just think that he provides great support for his products.

Thats when you have to consider your clutch set-up and your gear ratios. From my experence using JP motors weather it be a short/mid/large tracks, i've had good linear power from low/mid/top rpms ranges by tuning and dialing in my clutch set-ups, final gear ratios, and track conditions. If your track is tight, maybe you want to consider the way you have your clutch set-up or your gear ratios. I practice on a very tight track with a straightaway thats about 75 feet in length ( maybe even shorter ), and I have yet to come to any issues with my JP's having too little torque of low rpms on that track. Hit me up on my PM and I can help you with your set-up. Aloha :)

Thanks Joe! I'll check it out.

Roger: If you haven't seen it already, there is a MONSTER email sitting in your inbox.

No prob. Got it. Thanks.

Pictures of the Ninja engine being run-in are up.

Basically the engine is quite easy to start up and ran-in after 1-2 tanks of idle. Followed by the slow process of rich runs on the track to free up the engine.

What i gather is the engine has very good low grunt to fabulous mid-range. The driver comment that the engine is very driveable in the mid-sections of the track with very good mid-power. Revving up to 48k on the long straights of the track was a easy task. In the end, with engine being not fully tuned to the max, it was shaving off 0.2secs per lap.

It has very good potential. There was no time to test the different manifold lengths but what i have seen is great great results.



Disclaimer: no disclaimer coz its really good! :lol: :lol:

Wow, rev to 48K and still not tune to max , must be fast engine.... should be well over 50K when its done :D

can't resist

CRONO/GRP Falcon engines top three in the euros varm up race, Ninja engine in 5th place!

4 engines in the 5 first places is very very good!!!!!

And just to think, the ninja engine is BONE stock out of the box with no mods what so ever :nod:

I wonder how fast the motor will be in the hands of a engine modifier ( JP, Murnan, motorman, etc......... ) ???!!!???

Considering the quality of the engine :nod: in my opinion very very fast. :nod: :tire: :tire:

Any sites showing that results?

In my opinion, no need for that.. the engine is already good enuff. :sneaky:

it's never enough! faster! faster! faster! hahaha

Has anyone ran the MR12-T01?
