Cupcar crank goes snap

Oh the humanity

wtf?

one rod journal seperated from the rest of the crank.. nice purdy Ti rod

Show us pics of the oil tank ( I see it sitting on the shelf)

This is why you are supposed to freshen them every 40 hours...

What was this one revved too ?


B

Show us the head also. I'm betting there was some serious carnage when the piston smacked the head a few times..

Has Porsche Motorsports released parts to you guy's for the rebuild ??



B

Brad, this one was just refreshed..with parts from Porsche Motorsports...

oh the case is toast, the rod windmilled and cut through the main oil passage.... the oil tanks gonna get a nice ultrasonic bath...

Ive never seen a crank break like this..Ive seen the two piece failure before, not three pieces LOL

$$$$$$$$$$$$$

How much?

Paul

Look at how the rear main is beat to death ???


B

Loctite 540 on the case halves ?


B

oh the car drove part of a lap on 5 cylinders LOL..

cant read the bearings at all.. who know what kind of forces the engine saw AFTER the break while it was still running...


Paul I think crate motors from Porsche Motorsports are like $85000.... rebuilding this will be pretty damn close to that

Brad the car came to us like this, we like the Dow 730 for the cases

Freshens are upwards of 45k depending on if it arrives at their door in a running condition or not.

Yep. I like using the 730 myself (now)



B

Not sure if you knew this, but I thought I would point it out.

I have the factory GT3RS/R manuels on this server if you want to download it.

Right click on it and do a "save as"

WOW cool....One of the guys at my buddies shop works for Racers Group.. hes in Portland right now I imagine he has the manuals, but Ill grab this for myself

Izzat rod cap now friction welded to the crank journal?

JP, no the rod cap was just posed like that, the crank broke on either side o the piece pictured, also the counterweight broke off
