Looks like a blown motor to me, anyone know if this can be repaired? Otherwise I am parting the sled and shopping for next year. Only had 3000 miles and finally got it dialed in this year, one of my fastest sleds, even smoked my Apex......

To much boost not enough fuel looks like
 
Yep, I agree, anyone know if it can be filled and milled down or is it shot?
 
send the pic to Dave Marshall at Hurricane Performance.
 
8-9 lbs which is too much without head studs and upgraded gasket. Decided I am going to part the entire sled out including the turbo and put my money towards the new SR Viper! Turbo has less than 300 miles on it.
 
PM me prices as well. Im not that far...might be able to avoid shipping some stuff.

No its not, the stock nytro motor can handle up to 16lbs of boost with the right fuel (i.e 116)... I believe you were running to low of octane fuel, bad fuel or tunning too lean... You know the saying "to lean - to bad"

Sorry for your luck, hopefully a learning experience....
 
Post a price list of the parts you are selling. I'm possibly interested.
