Hi all, my 21 is jetted and putting out 63.7 hp at the wheel on the dyno using tyga pipes and open carbs with standard gear in them (big mj of course), i have a hrc kit in which i want to install but really wondering if its worth it so my real question is how much more power do you think i can get out of her using the kit??
is 80hp acheivable??
cheers for all the help
