The top end from my understanding is about the same on the 2057 and 2058, but the bottom end is much nicer with the 2058.. I haven't had the pleasure of running the 2058 yet.. IMO the 2057 is soft on the bottom, so a light weight clutch and stiff springs is need if using that pipe IMO..
Thanks for your reply. I have already broke-in and tuned the engine on 25%. So I don't have an issue with that however If i was to Run on 30% nitro, would I need to adjust the shims??
Also, what I want to do is have fast top end without compromising the bottom end to much. I am using plastic clutch shoes and a stiff sping. And I have also bought a light weight 48t spur gear to help... What do u think??
