Novarossi 21-7 fms.
Anybody have a 21-7fms? Just wondering how these motors perform ie bottom end, fuel mileage, what is the pipe selection, glow plugs, etc. Thinking of trying one out but a p5xs is plenty of motor for the majority of the tracks I run on. Any input would be appreciated.

I find that unless you need more topend over the P5XS, then don't use the 21-7 FMS. It has more ports, so expect to loss some bottom end, more so if you need a lot of punch for clearing short run-up jumps. If you have a larger track that has plenty front run-way up to large jumps, then OK. As for most, the PLUS 4 is what most are looking for now from Novarossi.

the 21-7 fms has been completely spec'd out by jim hottinger himself for the american tracks. every driver i have talked to about the engine has said completely the opposite about the bottom end of this engine . feedback has been "this engine is like a bolt of lightning" , i wouldn't hesitate to make either one of the new engines (or any of the old engines) your next powerhouse

fms 21-7 kinda of act like a 28 motor for bottom end, and top end like some of the fastest 21 around, and that was in a truggy LOL.........

In comparison with a stock V-Spec, how does the plus 4 directly compare?
Hopeing the nova shits on it, as i can get both for a similar price and deciding between the pair

the fms is still kinda of smooth but hits hard at the same time, i know it sounds weird smooth but it hits hard, but it does both,
the plus 4 nova motor is very smooth and has killer top end...........
so to compare to an os speed, not sure excactly but both the fms and the plus 4 are awsome

Bottom end on the Plus 4 is smoother than the standard OS, it has a more linier pull like the speed, the FMS on the other hand i feel hit's harder than the Plus 4, and yes it's still smooth, the low RPM pull the FMS has is very impressive, and mid to top it is very nice. I will be using the Modded Plus 4 at the Psyco Nitro Blast in Feb.

Does anyone run nova plugs in the 21-7? If you do, then which one?

I really interesting with this FMS
How's the Plus 21-7FMS compare to new Plus 21-4 in terms of power and run times ?
Is it possible to replace FMS's head with the standard button ? (I'm not a fan of turbo plug...lol)
And I already have JP-3 pipe, is this a right combination with FMS ?
Anyone please...
