injector clinic re badges other injectors just like RC or PT ect... From what I know, they would more than likely be Rochester injectors... which are not really the best. I would say it would not hurt to be on the safe side. Making that sort of power to need that size injector would not be cheap to rebuild due to injector failure. for the little it would cost, it is very good insurance to send them in...the guy that built my motor "lost my 780cc precisions" i was pissed, brand new injectors... so he gave me some injector clinic 750cc injectors... so my question to you is, they have been through half of last race season.. are inejector clinic injectors good...?? and would you reccomend at lest a flow test?
