Hi, it all depends on how it’s set up and if it’s a tuned or standard RB kit, this particular one is not tuned but has had many hours of intricate time getting as much horsepower from it as possible because the owner races it, this one is geared for 85-90mph and was 25.8hp on this particular dyno, since then it’s now in another class and I was able to do some porting work and change the carb and it’s now 35hp but still gearing is set at 85-90mph, it can be geared to do higher top speed of 90+ but it wouldn’t be as quick getting there. When I build and tune the RB20 for the road I use the same gear ratio. There a great kit to use and respond very well to tuning. 👍🏻👍🏻
Hi Chris, that's great thanks for the reply, i've been more than happy with my standard RB20 although may well consider having some tuning done at some point, really is a great kit. Hope you have success in the new class!👍
Are these kits any good for a road/rally set up
Hi Chris, what kind of top speed would you be expecting from this RB20 kit?
