150 psi seems right, however you to need to use 93 octane at that range of compression. loudhandle lmao at yamaha. skidoos + speed = success deal with it idiot.
nitromethane has a tolerance of -20 below. i doubt i would ride at that temperature. there is guys out there that use nitro meth in there sleds. problems is finding them. we have done research on nitro meth just need some more info before we use it.
Has anyone used Nitromethane in there sleds? If so leave your number or number for people that have, or you may email me at improved_600@yahoo.com. any info will be helpful
