Hey all,

Time for a new motor, as I damaged my Hyper .21 8port this weekend (due to my own stupid fault). I was wondering what is the difference between the RB Concepts C6 and the S7WIII. Will either one work woth my JP2 pipe?

I'm not asking which one is better, I just don't know what the differnece is between the two.

Just as background, I race at Revelation Raceway in Monclair.

Thanks

as far as i am aware.....

a C6 will offer a bit more low down torque with a nice progressive power curve

whereas

the WS7 will rev a bit more and the power comes in a little higher in the rev range.

the C6 is a long stroke engine with MES (multi Exhaust System) basically 1 main & 2 smaller exhaust ports

the WS7 engines have a "square" configuration where the bore is the same as the stroke & in "theory" should be higher revving engine although this isn't always the case likewise the longer stroke engine should produce more torque

venturi size, state of tune & pipe selection will have more of a deciding factor over the above variables anyway

Thanks all,

thats what I thought.

So a C6 with a JP2 is a good choice for a medium track? I would like to not have to buy the 2045 pipe, just to save a little money.

If not, then I guess I will go with a Rossi P5.

Thanks.

Running a C6 with JP-2 right now and it works great. Be prepared for the monster bottom end of the C6. It takes a bit getting used to. Top end is great with that pipe too but I've heard 2045 + 92mm header is the real ticket for the C6.
It's easy to tune and it runs pretty cool in a good race tune with 30%.

Never ran a Ws7III so I can't compare the two.

I run a WS7iii and its awsome, got a JP1 pipe on it and it gives great torque and loads of top end. I know some one who has C6 with a JP2 and it rips. he is the top contender in my area. I have jeard the JP3 is great, gives both top and bottem end power. But both are good engines, whatever you choose from RB you won't be disappointed

what about WS7II and S7.. anybody know about this engine.. which one is better.. and whats the different between WS7II and WS7III
