Nytro S/C Boost (180 kit) & Upgrading Requirements?

[Krummy]

As far as the heat exchanger goes, does it have to be the ones from performance shops or will something like the link below work from an MTX? My sled is an 09 FX Nytro 121"

You can buy a mtx cooler kit right from Yamaha includes everything you need to install. the aftermarket ones look to be longer and might provide better cooling.

Be carefull with boost limits on pump, I found the limits in Maine last year I run a ulmer racing stage 3 turbo with a gtx turbo, upgraded fuel pump with rising rate regulator, cam timing for boost, arp head studs, cometic .66 head shim from ulmer, mountain tech tunnel cooler mated to a f series mounted sled cooler I fitted by the snow flap works very well. Sled runs very consistent in the trails between 155 to 165 degrees. Had the boost set at 8.5 lbs with 12.5 on the afr gauge which I had been fattening up and lost the head gasket on a long strait away pull. So alls it takes is one bad tank of gas to end it
