IMO v-specs are one of the best bang for the buck
and nothing last forever thay are race motors that
wing at 40,000+ rpms putting out 2.5+hp and only
cost $300/$500 not bad

these motor's DO NOT put out 2.5+Hp.....a Big Mod picco/jammin .28 will pull a genuine 2.5.......but a race .21 will be hard pressed to pull a True 2hp...there are a couple that come real close...but they aren't there yet.

i was not claiming any rpm or hp faxs just that i
think a nitro motor for what it does is not a bad
del the rpm/hp output per dollar is good
look at a f1 motor rpm/hp per dollar
i think we get a lot more bang for the buck

I highly doubt any .21 engine even carries a true horse power...so all those number ratings, "2.5hp, 1.0hp" is a marketing gimmick.

You have to expect something to go wrong dealing with any of these engines, regardless which manufacturer it is. They dont run these engines from the factory, so there is no "tests" being done on your product once purchased

I have had motors from the manufacturer go bad, and i know for certain it wasnt my fault, but it was never an OS engine.

I did last year crack the crankcase on my EB modded Vspec (8 gallons old or so) i purposly bashed the car around the track, got aggrovated and over shot a jump, bam...case closed.

ever since then i havent had an instance with any of my Vspec motors...they run great, have excellent fuel mileage, and tune very very easily. The only other motor that i know of that was easier to tune, was my old Novarossi P5X.

you are mistaken...there are multiple .21's that carry a lot more then 1hp on the big end.

O.S. stands for Oh Sh!t the case broke or the bearings went out.

thats funny, and im not trying to knock you by any means, but the TRUE definition of "horse power" is 33,000 lb.ft./minute. I doubt any one of those engines could pull a quarter of that....in fact auto manufacturers have abused such ratings for years, some of which are actually true. But to put into perspective....1 hp ≡ 33,000 ft·lbf/min

RPM ratings? sure...but actual horse power ratings...not true at all just by looking what a true horse power rating is. i could tie my nitro buggy to my ankle and pin it WOT and it wouldnt move an inch.

go carts carry 3.5 horse power, and they have to carry a full grown man....i can hold my kit with one hand and it wont go anywhere.

and thats IF the go cart even truely has 3.5HP....or 5.0HP

my old Camaro Z28 boasted 300HP....but that was 300HP at the fly, 276 at the wheels on a totally different dyno with different software..

its a good reference point for these engines for whatever software they are using, but those numbers seem to be really exaggerated

LOL


on a side note....

i have a vspec. 3/4th of a gallon the rod blew. i sent it to them and they sent me an invoice i called to see what was going on they told me exact words "we did not find any signs of misuse so we are going to warranty the connecting rod for you, if you would like us to replace the piston and sleeve as well as the bearings it will be 119+ shipping and handling"..........

i was like wtf cause the rod was what damaged the p/s and rear bearing. so i ended up gettin it back with the new rod and put new tko bearings and the ninja p/s and im breakin it in now....

my dad has a vspec and it has a good 6-7 gallons thru it and he JUST replaced the bearings and resealed the whole engine and this thing has awesome pinch left. prob enough for a good 10+ more gallons. it seriously feels like it just got broken in. if my engine does like my dads thats all that will keep me with os.

in a perfect world wher there is no tire/road slippage, yes the nitro engine will pull a full grown man, only and only if you sit on a near zero friction surface.

who ever said that nitro car can't pull you by tying up your leg.. LOL...

it's all physics my friend..
