Nurburgring. It's in the town of Nurburg, not Nuremburg. Confusing, i know.

Also its a team of guys that build them @ the GMs high performance build shop up in Wixom MI.

Remember when we talk cranshafts were talking tenths, rzs, cpk's, lobing, hourglass and such.

Generaly the pin grinder is running out of spec. There just not where they are supposed to be...

rz's and cpk are surface finish. If I remember correctly rz reffers to the roughness if you will. You get a rougher grind the quicker you run the diamond across the wheel.

CPK is more of a valley or hill above mean.

Lastly you have the Adcol reports. These show full surface finish, lobing, hourglass, position, pin parralel and other vital specs.

All of which are out at one time or another.

And the big biggie! Cracks in the cranks! Ypu all the sudden one day they just noticed them along the forging line on the thrust wall main bearing...

lol!! well they did specifically say that they had "one" guy who builds the motors for those cars, but i have a hard time believing that as well

The Ford GT is the one that has a hand-built engine, Corvette is mass produced. You can't meet a value price point with hand built stuff, doesn't happen.

We need not elaborate, though, GM is doing a pretty good job of humiliating themselves as it is. It's bad when Ford and Dodge guys start feeling sorry for them. Well....no it isn't, it's just funny

they dont have one guy that builds all the motors the motors are hand built by a team of guys only one guy works on that specific engine. and ryan what was off? i highly doubt that any part on the crank can be out of spec by much without having a huge failure. something seems off there. either way the z06 is a bad ass car and it is the second fastest car around nuremborg (sp?) second only to the porshe gt2 i belive. (motortrend 05) it is a highly reviewed car and there isnt anything that can catch it for the price.

interesting, on the show they said that they have one guy who builds all the motors. that would lead me to believe that they have some interest in building a quality motor. but then again i am a ford guy so i think chevy sux, lol

Heres a bit of valuable info on the Z06 LS 7 powered vehicle.

Place where I was working is the place where the crankshafts are made, the ONLY place.

They have been making them for a year and STILL havent made them to actual print specifications. GM Keeps taking the sub standard product to keep the motors rolling off the line. Afterall they are getting over $14K for just a crate motor...

Hey I am watching a show on speed channel right now about the 2006 z06. I guess that would be new last year, but considering I'm a ford man this is the first time I have really paid attention to it. I have to admit that thing is bad!! It weighs in at like 3136 or something, that is less than the porsche carrera gt that is mostly all carbon fiber!! 0-60 in 3.7 and sub 12 second 1/4 mile. OMG now they have the queer rainbow warrior Jeff Gordon on here testing it. Anybody online turn it to speed now and check it out!!
