One particular engine we mod, I've heard guys getting 10 minutes easily. Another guy gets what I get, around 8.5 minutes. The guys that are getting 10 minutes I noticed are on-road guys that seem to be very smooth on the throttle and smooth around the track...

There's dozens of variables that play into the runtime external of the engine...driver has a ton to do with it
I've got well over 10 mins on a 50+sec/lap open tracks all over the country with my Vspec...and thats at a good tune, not leaning it to meltdown. There's no 'miracle' engine, never has been, never will be. Practice tuning with a bit leaner bottom than most, a low idle and you'll find your not at WOT nearly as much as running a rich bottom / lean top like most everyone runs.
Ninja's don't have a expoxy'd crank. I'm not defending the GRP cause I don't even know if I'm going to buy one but there clearly not the same as a Ninja.
Do the MRTuned Ninjas have an epoxy'd crank?

hey, it maybe JUST a Ninja ........ But i like it. Needed a new motor and it fitted the bill. Came with a pipe etc in the box and i couldn't knock the price. It was easy to do the running in, tuned pretty easy although im still rich as just finished the first meet with it. It's as fast as anything else on the track and i was able to do 7min fuel stops with it rich. Didn't have any issue's with flame outs or it cutting out on me !! what more do ya want ?? I'm sure Ninja's are just the same ................

I have bought,modified and contune to run Ninja engines... I also have the same FLS 2053 pipe........ very very good engines !
From the picture links posted above, it appears that the new GRP engines are really the MRT Ninjas with a different head and color scheme (and a lower price!). The decals are even the same from the MRT Ninja. They should be killer engines...

I hope we can get the non MR tuned versions as well for an even better price !!!
i just happen to have a new ninja bo1a piston and sleeve set sitting in front of me and they are identical to the grp parts! i know the mrt ninjas had the epoxy filled cranks and magnesium heads, but what else was done to these engines?
kinda funny how much run time you can squeeze out of an engine when you lean it out to 300 degrees and use a 6.5 mm carb restrictor major runtime !!! and screamin , oh buddy !!
Yannick ran a 5.5mm restrictor, most of the top guys were going way down on restrictors because the track was very loose during buggy qualifying and huge power just made for a lot of wheelspin and slower lap times.

I think the first Ninja sleeves didn't have any angled cut ports. I remember looking at mine when I had it apart, it it looked like just plain port cuts, no angled in cuts from the bottom. I also remember someone stating Jim at fusion said they were pretty rough cut also. Maybe the new sleeves have more work done on the ports.

I have an original NIB .21 and .28 .... I will do a photoshoot on them very soon...both my mills are are the non tuned version.....they do not have the "modded" sleeve........the MR tuned Ninja's had the angled cuts, not the standard NInja............. I certainly wouldn't pay an extra $100.00 for MR treatment..I do much nicer work myself LOL !
major runtime !!! and screamin , oh buddy !!
