Ws7 II x3 question
 

Is the X3 still 2 needle carb? How does the power differ from the Ws7II?

RE: Ws7 II x3 question
 

It is sill a 2 needle carb.. the only diffrence is the carb was redesigned to make it easier to get to the throtle needle on your buggy. It's a great engine that will not disappoint you at all!!

that is a awesome engine. I just bought mine a week ago. I half way broke it in friday night, and sunday (while still running VERY rich for break-in) I was passing fully tuned buggies.

I also love how they redesigned the carb. they made it backwards so everything fits better.

i had mine on thursday and it looks awsome yeah carb is redesigned
what do you guys reckon clutch wise will a rmv speed 2.5 be fine and for pipe the eureka pro 2027

anyone know the power rating one that engine? Just ordered one for my hyper 8. Thanks.

RE: Ws7 II x3 question
 

It has more than enough power for pretty much any race track. My local track has a pretty big triple, and the ws7 is one of the few engines to clear it. My sportwerks .26 will only barley make it if i line up perfectly.

soon young grasshopper......soon[>:]

An RB Concepts motor is one of, if not arguably the best racing .21 out there. I've been racing them consistently for three years now and I have never had any trouble with any of them. The WS7 series motors are powerful as well as incredibly fast. Most importantly their reliability is second to none. The WS7 series has more than enough torque and top end for any track out there. If you are a really good driver in 1/8 scale and have great throttle control, the C5 BB will smoke them all in the torque department. However for me, the C5 has way too much power for me to handle. Good luck to anyone who is looking to purchase one or whoever has one:) Their prices are steep but its well worth it. It will outlast and outperform any sport motor two times over without a re-build and hold a tune like no other:))

HEHE well the C5 is a little out of hand in my buggy, but great in my truggy!!! I am going to attempt to run the 7mm venturi in the carb for the buggy to control the power a little.

RE: Ws7 II x3 question
 

so both the s7II and ws7IIx3 have the same performance?

RE: Ws7 II x3 question
 

The WS7IIx3 will have a litle more power..... it has a bi turbo crankshaft in it... the S7II only has a turbo crankshaft. Many have said the S7II is easier to drive with a power band that is more smooth.
