My Novarossi has over 12 gals. through it, My V-spec lasted 1.5. put in new bearings, con rod and got 1.5 gals through it before the crank snapped. I'll stick with Nova. Sirio makes very good engines as well. Right now I'm trying out a Go motor, so far so good but we will see I've only got about a gal. on it. Makes good power for a $175 7pt.

How long should a ninja last? It has a better case and crank. So how much better is the coated crank over the vspec crank?

going into a D8. i swear by nova, but vspec is cheaper
Why always eating the same? There are new motor manufacturers on the market these days who give us fast but affordable engines. I also raced Nova for years but I am hooked on the performance of my 7p Go engine!

I run the high end vspec (speed) and I absolutely love it. Its easy to tune, holds a tune like no other engine I have owned. I know the vspec's have lots of bottom end. I have been told the +4 is missing some in the bottom end. I have seen vspecs pull hard at the track. People seem to like their +4's but the review I read in a recent review that did not like the simple design and simple components in the +4 (bearings, crank, carb) Thats just what I read. Bottom line is I would go with the vspec.

I have been running the Reedy 121vr in my 2.0 for about 3/4 of a gallon and it hasn't given me any frustration what so ever. It's fast and is getting faster. I can clear the 18 ft quad with like 5 feet of run up.

It's easy to tune which ilike. I have only been running on a tight indoor track so I don't know if it has alotta mojo up top but we will see. @ 225 shipped it's a pretty sweet deal.

We are currently running the speed 2 and very happy with it in the run time depending on pipe 11min in a buggy easy but like i said depends on pipe. I have been looking at the Max engine range tho but will be hard to leave the speed as we have had 1 flame out in over 12 months.......

Get Plus 21-4. It is tuned by NovaRossi, and it is so smooth that you won't wasting power for just spinning your wheels for nothing. Also, it is much more long lasting that Vspec. It might be even cheaper than the Vspec. Check this out:

both engines are VERY good, I persionally have owned both of these engines. im currently running v-specs in my buggy and truggy. a slighly modded stocker in the buggy and the speed in the truggy(i know thats sounds backwords, dont judge me). once you learn the ins and outs of any engine you can make them last a long time. i have had my speed since DEC. 08. and my stocker since late JAN 09.end i race EVERY weekend

the only thing ive replaced is the bearings in the stocker, just because i wanted ceramics.

speed had 12 gallons.
stocker has 9 gallons.
v-specs feel better for the gearing in the d8/d8t
i have had rossi's go to the 10-15 gallon mark aswell.
eigher way you are going to get a good motor,

best of luck

I am interested in trying out the sirio, heard very good things about its performance but heard nothing on durability, i dont really want to spend that kind of money if I only get 5 gallons through it before a major failure.

Anyone had a sirio for a lengthy period of time and what is your opinion?
