it's too bad that the OEM's have made the engine packages so small now and there is no room for monster big bores.....but turbo's have filled this need for HP quite well and are getting better every year.....it is good to see that the Boost-it crew is building for more than Poo/Yamaha now, a true canadian company that will bend over backwards to help you out until you are happy.....every sled seems to a day here and there that they just aren't right (stock or modded), and as for a turbo sled, clutch maintenance is key, the clutchs take a beating, keep them maintained and they rock.....you just can't ignore a turbo like a stocker
