well I can say that the ws711 has wicked insain power all through the power band. top speed is nuts as for the s7 i have no idea i have never ran that mill
 
I have a Ws7II and have yet to break it in as I am still waiting for the buggy it will be going into. I got the Ws7II because I heard it has a good balance of power and also because it seemed to win a lot of big races this year. I believe the Ws7II is also supposed to have a longer life span than the s7II but they are pretty close in power output but Rb dosen't put out there engines hp and rpm numbers.

Whats the difference guys? Power wise...RPM wise...About $75 difference is it worth it?

RB don't put out bhp's etc etc as they state that they are irrelevant and very much depend on the tuning by each individual. The S7 and WS7 are basically the same engine, the W standing for WORLDS (essentially the pro version if you like)... it is more powerful and newer than the S7. As for the price difference and which one to get, it depends on the use, If you are bashing then keep the cash and buy something else with the $75, if its for racing then get the WS7.

As soon as my Collari dies thats what i'm getting. (the WS7 II)
 
depending on what your going to use it in. i might recommend a Novarossi instead. Nova's have more bottom end than RB's and are more suitable for monster trucks or tight tracks. RB's like open tracks where they can stretch thier legs and make the most of what they were built for. this is of course assuming comparable models from each manufacture. say a 421B from nova and a C5 from RB, or a P5 from nova, and a WS7-2 from RB.
 
Now, for the price of all these would you get any of the said engines or would you get the the V-Spec? All I hear is good things about it.
 
well i own a vspec and love it. but if i had to do it over again. i would be hard pressed to choose between the vspec and a nova 421B assuming they were very close in price. over a P5 or ws7-2 id take the vspec hands down.
 
if you are going to go with an RB other then the ws7II, then I think you need to look into the s5, or even the c5. They are both much more balanced when it comes to torque and top end.

I personally have the s5 in my k3, and am very pleased with it. The top end is there when ran around 240, and it has the power the ws7II lacks down low.

I will probably try the new O.S. or the ws7II next season, and then just use one of the two for a back up to an s5.

It all depends on what you plan on doing, I got the Ws7II because I plan on it being my race engine but if you are just gonna be bashing then go with the s7II and save some money. For racing the C5 might not be the best choice as I have heard it has so much power it can be hard to keep under control but for bashing why not, it is about $50 more than the Ws7II though.
 
The S5 is the least of the RBs mentioned here, still a great engine but not a patch on a properly tuned WS7II. The C5 Is an absolute monster, and probably too powerful for racing beleive it or not.

At my club almost no one has any problems with tuning, reliability or performance. The same CANNOT be said for ANY other engines and the includes P5's, OS' V-specs, Piccos or Hyper 21s.

Go RB and you'll never regret it!
 
if you go with an Rb make sure you check out RB's forum, vast info on tuning RB's. according to everyone over there RB's (mainly the WS7II and C5, s7/s5 much less) are VERY clutch and pipe sensitive, and have there own way of being tuned altoghether. but everyone also claimes RB's once learned are the best mills on the planet. if i didnt have a v-spec know id go for a S7II in a heartbeat.
