i purchased a set ran 10 passes @7lbs of boost .. motor started smoking like van Ryan's express .. pulled the pistons .. rings were stuck... yes ring('S) LIKE ALL OF THEM .. Called MTC .. Sent pistons to MTC ..got a call today .. MTC said the pistons warped and distorted and it was my fault for putting NOZ flat top pistons in a 7lb boost turbo motor .. i told him for 2 years i ran stock piston with up to 14lbs of boost .. Cliff then told me stock pistons have a better top ring land ..and that's why the stockers lasted ..Well if them MTC pistons can't with stand 270hp ..then whats going to happen when somebody sprays a 140 shot of NOZ .. oh and don't let me forget when i was ordering my pistons for a turbo bike ..MTC recommended these pistons along with the 2mm shorter turbo pistons .. and when i got the pistons they sent the wrong wrist pins ..
my dealing with MTC is over never again..
and you guys are pissed over 50.00 that jeffo took ..
i got screwed out of 700.00 plus 200.00 to coat these piece of shitt pistons
