Hi, after a recent air filter split caused the death of my S7 after over 2 years of reliable racing, I want to stay with RB and take a step up.

What are the main differences between the WS7 & C6 when being used for club racing and which keeps a tune better as my S7 hardly required any re-tuning during the two years of racing and was a joy to use.

The WS7 is based upon the S7 and is adapted for racing, you should have the same relaiability as the S7
The C6 is more powerfull then the WS7 with the same relaiability.

As for the tune, an engine always needs some retuning, it all depends what you ask from it, if however you only do clubracing then a normal S7 will do the job quite well for you.

Thanks Rody

Looks like I will go with the WS7, as it seem the like the logical next step up in performance, as the C6 is probably a bit much for club level and wouldn't be maximising it's potential.

Jammyboy if you like the S7 I would just get another. The power curve is very different on the WS7 and you could end up going slower (I know I did).

Plus moving to a turbo plug thats on a WS7 you will find the tuning needs to be more precise.
