will an aftermarket revbox raise top speed because it will have the extra 1000rpms

 

well it depends on what quad. to find out just think if when ur going top speed on ur quad, is ur quad hitting the rev limiter? if it is.. then yes an aftermarket revbox will raise top speed. but on my 300ex when im going top speed im not hitting the rev limiter (from what i remember) so in my case no it wouldn't. i think that rev boxes are only good for heavy modded engines that can benifit from the extra 1000 rpm's but i think it wont help u much. spend ur money on somthing better like a pipe
