I've got an 8 port Hyper21 in my MP7.5 and it gets the job done. I will openingly admit the motor has no bottom-end power period...I always get left behind off the line, but once I get in the higher RPM, the buggy does pull quite nicely. This is my first engine, so after this one dies or blows up I'll go for a better engine, probably a Sirio 21 or Rex P5.

I also have the Hyper and I agree it doesn't have the bottom end. But if you get your clutch adjusted right so it kicks in later it works pretty good. In hindsight I should have gotten an O.S. RG.

Thanks for the opinions guys. I just didn't want him to dump a bunch of money into building another motor if it wasn't worth it. I've read good things about the os motor on tracks that aren't really big, or are kind of tight. That's probably the type of track he'll race on the most. I'll be running a duratrax torq .21 in my K3. I won the motor in a forum contest, so no complaints from me. It was the stepping stone I needed to get into an 1/8.

What weight oils should I start with for a 777. The tracks are usually dusty and loose or loamy and loose. Thanks.

I d say go with 5-5-3 or if you find out while driving that 3 for the rear is too much go with 2000. Shocks 60F and 35R.

This is one of the best setup to begin with, with the triple seven, according to degani and mark p. They 've worked for me...

If you had the choice between the V spec and the Sirio Kanai, which motor would you rather have. I maybe trading my K2 for a nib engine. Just wanted some opinions. Most tracks I will race on aren't very big.

What is the best way to install clutch springs. I'm having a hard time getting my 777 clutch springs on. Should I just get one of those Sportwerks spring installer. B/C don't you have to do more maintenance with aluminum shoes. I've never had them before.

I V-spec is an awesome motor, but if you got that one, you might want to pick up some boca ceramic bearings for it, the stock bearings have been known to be faulty.

It's a rumor going around. The other rumor going around about the engine is that it's very fast, very dependable, and the bearings don't go out.

My guess is that a handeful of engines had some bad bearings in the beginning and there are no problems now. I'm not certain. There could be a bearing problem. I just think people over react due to the VO1-B having bearing problems when first released.

Plus, I don't know what to think about having ceramics. You may end up replacing those before the engine is done.

For the clutch springs... go with the Sportwerks tool. I ve tried it... It's not perfect but at least you can get away without stabbing yourself with a screwdriver.
As far as the V spec is concerned... I dont think that this engine is flawless, but it is one of the best I 've tried. I have changed my front bearing at the 2 gallon mark, but this $15 fix, I wouldnt call a problem... I have spent houndreds on engines that never made the 2 gallon mark.
GO V Spec!!!

Default Engine bearings

A little off the subject but, Aren't ceramic bearings illegal for use in ROAR racing?
Anyway I'v had bearing problems with my Top engine too. There is no engine that is immune from bearing problems. I had 2 bearing failures in my top and both seemed to stem from the seal coming off and letting dirt into the bearing making it wear very fast. The third braing I smeared RTV around the edge of the bearing making sure to get some on the seal and have not had a problem since. That engine finally expired at 8 gallons and I have done the same thing to my new moter (Rex) basically then same 421B. I've got 2 gallons through it and no problems yet.
