Hey Brian;Do those pics look familiar? LOL

 

Wow, thats interesting. It doesn't look like detonation to me either. I'd place my bet on the piston design - not built to stand up to the high heat and pressure generated from supercharging. I'm really surprised that it happened with only 6psi.

Do you know anything about the composition of the pistons that Nissan used in the Titan? Its almost like the engineers took the hypereutectic piston design to the extreme, making a tighter fitting (better power and emissions) yet much more brittle piston in the process. When you blend silicon with aluminum to create the piston, the alloy doesn't expand as much under heat, which would allow for tighter tolerances. Too much silicon in the mix (or poor casting process) can cause a significant reduction in the strength of the metal.

 

Thanks a mill for the reply guys...

 

It could be the composition like you said, but also how they heat treat them. They might not be cooling them quite properly in order to make them a true hypereutectic. They could be cooling them too fast and making them more brittle. I would think you would see it on the top of the piston though. There's a greater pressure differential between the first and second ring, so maybe that has something to do with it.

 

I'm sorry to hear you are having problems so soon. Why don't you take the charger off and have the dealer warranty it?

 

Now thats an idea, Thanks. I might do that....Hey what do you think about the new Seirra Denalli in a 2wd flavor? Think aftermarket support will take a while on that 6.2 w/a 6spd?

 

I read on another thread your gonna ****-can the titan and get a chevy...You'll be happier but it's nice to see some imports on here and hear what they have to say! But if the problems are as bad and wide spread as you say then...get on board and go get yourself a denali

 

A Radix will be available for the L92(engine in the denali) by the end of the year. You can run prochargers or turbo(s) right now on them. The tuning is endless as long as you dont get one with displacement on demand but Im sure that will be taken care of shortly.

 

Have the dealer fix it and just sell it before you have more problems. I am sure you can sell the radix to someone on a forum. Buy a Denalli and put the 122hh radix on and go from there.

 

If you add a blower to a GM you might roach a piston there, too.
**** breaks.
Really want to make power? Buy a 2500 D-Max w/Allison and do the exhaust and program. It'll put out @ 600hp and 1000lb/ft tq. That's power!
