I am very disappointed with the turbo I purchased from push turbo. it has been over 4 months and ken hunter owner of push turbo has not shipped the clutching, or intake adapter. the mapping he gave me is incorrect, and the motor will not exceed 4200 rpm. i have been persistently calling him he will not answer the phone or return calls. save your self the headache and buy a different kit. he will not stand behind his products. with his poor customer service he will probably be out of business soon. call me with any questions. I can go on and on about how disappointed I am with a $7500.00 that does not work. he was paid cash in full, and said that he would send me the missing parts in a few days. four months later i can't use my snowmobile, and he won't answer his phone. don't trust him or his kit Mark Mader 612-221-2906
