Well i just spent my money on a boat, but im going to get a losi 8ight 2.0
with some really high quality servos and good sektrum electronics
But i was going to get the grp .21 tuned engine for my buggy... but they are discontinued....
So what's another engine that is just as good if not better performing...
Ignoring price what is the best? Cause im spending a lot on ever thing else so why not get the best engine.
What is the competetor for the grp .21 tuned egnines? What is the best engine avaliable right now anything better than the grp .21 tuned?

It's easy enough to figure out which engines are considered the "best", (just check their prices on Amain ((as a yard stick)) ) but you also need to keep in mind what you're looking for in the engine. It depends on where you'll be driving your buggy as well. Is it a huge track with long straights? Or is it small tight and technical? Maybe it's a medium sized track that you need and engine with good overall traits. These are factors to keep in mind when getting a new engine.

Top of the line engines include OS, RB Concepts, Novarossi, etc...I'm sure loads of people will throw more names into the list. Also keep in mind that you can send these engines off to get modified to even further enhance performance for what you want the engine to do.

Have fun man.

grp discontinued wouldnt detour me from buying grp. if i could swing it id get a novarossi+4. a little cheaper then is the jx ninja 21.

I've heard some good things about the Werks Team Line B7PRO, 08 Spec, Ceramic but I'm a poor man so I use economy engines that are just about as good and parts are easy to come by for the SH 21 Pro Buggy Engine, '09 8-Port - Ceramic Piston

Have also heard lots of good things about that Werks engine... It's probably what I would get were I in the 'hood for a new engine. With deeper pockets I'd get the JX Ninja...

My friends have the Werks TL B7 engine. It is a good engine. Decent bottom end, screams on top. One had problems with their carb sticking. It runs god though. My next engine is going to be the OS V-Spec from ebay at $240 shipped, as I cant pass that deal up. The JX Ninja is $300 and a better engine IMO. Also look at the RB and Novarossi engines, very good quality, second to OS in tuning, adn second to none in longevity. RB is made by Novarossi.

Youre giong to get a hundred different opinions from a hundred different people, it's more of a matter of opinion of which engine is the best, pretty much any well known brand is going to be a great mill, some will hate certian engines that others love. As far as what you want the engine to do depending on track layout, the gear ratio and venturi inserts can aid in tuning the engine down or up for he most part. Good luck on your decision.

there are also some budget engines that will really do the job well. LRP engines are good and are super reliable as well as some dynamite motors such as a mach 427 (losi also makes a mach 427) the picco engines are good as well and even better if you get one modified.

if i were to pick a race engine it would be something by os. they are pretty top notch. rb and nova are nice but its hard to get those parts sometimes.

Depends on what your criteria is for Top Of the Line.
Tunability, Power - low end -mid range- topend, cost,
reliablity, driver skill ect ect...

How about your track or tracks you plan on racing on.
Long, wide and smooth or tight and bumpy?
High grip or low grip surface? Hard on tires
or easy on them?

What about your skill level? Be honest with yourself
if you can't handle the power of a top level engine
you will be faster with one of the cheaper sport mills
the NovaRossi N21 comes to mind.

Truth is I can't handle all the power my V-spec makes
with the 9mm restrictor.
We ran the first round of our state pro series yesterday
and I qualified 4th for the Sportsman Buggy A main.
About two corners in to the 30min main I spun the
center out of the rear brake rotor, after that I
was plain out of control. Several hard crashes later the
left front steering knuckle went and I was done.

If you had asked me on the stand at that point if I
would have liked to have a smoother easier to control
motor the anwser would have been yes. Add to this
that the track had become very abrasive on tires
means you will finish mains on slicks if you don't
have proper throttle control.

So give us a littile more info.

1. Budget for motor and pipe.
2. Driver skill level.
3. Track or Tracks layout.
4. How long do you expect or want it to last.
5. How is your tuning skill.

I just picked up OS speed Vspec with 1 gal through, and I hear nothing but good about this motor, and high rebuildability.

I can't wait for the O'donnell 21 motor to become available too. at that price I have to get one and try it.

What is the O'donnel engine exactly - a VSPEC clone or what???


VSPEC's have great power, but they do have a rep for needing new bearings very early, and losing compression quickly, or outright just dying early(I've seen it happen at local races a couple times.. - newish VSPEC's kicking the bucket.. And not in the hands of clueless newbs either..) For me anyway, based on what I've read, I would think twice or three times about getting a VSPEC.. I like the power I've seen from them.. But I don't want to have to replace bearings or have it just die at a gallon... Just my personal take on it though, so no offense to the hardcore VSPEC fans...

Does it have to be nitro? A good brushless conversion will run circles around ANY nitro engine, and do it much more reliably, while giving a much longer service life. Try converting, you'll NEVER look back... unless you have to compete with a nitro only class. In that case, you can't go wrong with most of the better brands.

Action movie on mute.

That the BEST description I've ever heard! But the "Action" is FAR more intense. With about 4 hp on tap, and GOBS of torque, brushless is simply Faster.

Pardon my ignorance but what means brushless conversion means?

The new V-specs are much better, issues have been basicly completely eradicated.

Converting an 8th scale to a MUCH MORE POWERFUL brushless system. No more flame outs, tuning, glow plugs, ignitors, fuel, starter boxes, clutch issues, or any of the typical head aches associated with Nitro. It turns an 8th scale racer into a very convenient MONSTER. The class is new, and emerging. But like anything else that has an establishment to get past, it will take time to catch on. Watch; this time next year, they will be substantially more plentiful. I don't think Nitro is going anywhere, but once you have one of these things, you'll scoff at the idea of fighting another short lived nitro engine.

Well im my situation i want to stay nitro...
I want TONS of power!!!!!!! TONS of top end speed!!!!!! And even more acceleration!!!!!!
I am looking only at the top of the line engines...
The track im racing at has 1 fairly long straight and TONS of sharp turns and big jumps. (So i need good acceleration too)
Any point .21 thats would fit my needs??? It need to be good performing and has to be tuned...
i will be running 30% fuel and i can adjust the shims if i need to...
Any suggestion???

Thanks

Dang! Never thought it meant electric converted lol...gotta see-test it, but I do love the nitro even with it's own headaches and constant repairs.

then brushless is what your looking for!

man i raced against a brushless 8ight last saturday and damn that thing was insane. he could clear jumps like they were nothing and he didnt even need to run up to it like everyone else did. he about jumped off the track a few times

How long last vs the nitro counterpart in a practice race for say?

no idea because i dont have one and never have driven one.

I'll give up RC before I go brushless.. I just think they're that lame. The thrill is gone, however fast they might be. This is a motorsport for me, and the smoke and screaming sounds are all central parts to it. Period. Just my $.02 of course...

If money is no issue then just get the OS Speed.. Long lasting, easy to tune, gobs of power... There are just so many options out there.. Again though, I would get the JX Ninja... Just look at in the Mugen truggy..:

In a buggy it'd be even faster...

You want a Clockwork modified JPX .21 ! nasty, evil powerhouse of a .21....You will not find a stock .21 anywhere that will throw down like one of these do....

Supertib has alot of time and equipment invested in moding nitro engines so I
would take his advice, but get a set of restrictors to go along with your new
toy in case you ever want to go 10min between fuel stops or you want to
finish 30 min mains with any tread left on your tires. A 7mm,8mm and 9mm
should give you enough tuning options.

Honestly a engine that trys beat you into submission every time you
take it out gets old after a while, at least with the restrictors you will
be able to tone it down a little.
