Insight to the C7Z06 & ZR1
People may have posted something similar prior if so I apologize for the rehash but...
Have you seen the new Cadillac XTS? Car & Driver has a write up on it. I just saw the commercial for it and I think it gives us good insight as to what the Z06/ ZR1 will look like... Assuming they make both (probably). I suspect of they will have a Z06 & ZR1 and the Z06 will have a supercharged 6.2L and the ZR1 will have a twin turbo 6.2L. Your thoughts?:lurk: |
twin turbo would be the schizz!
|
That's been my guess for at least a year but I've doubted it here lately
|
I suspect of they will have a Z06 & ZR1 and the Z06 will have a supercharged 6.2L and the ZR1 will have a twin turbo 6.2L.
Would the difference between those two motors be enough to differentiate the two models? |

Would the difference between those two motors be enough to differentiate the two models? The fact is, superchargers take power to make power vs turbos use essentially what is waste energy (exhaust). The favortism with superchargers has always been low-mid rpm torque, but with variable cam timing and ever advancing turbo technology, this is becoming less true. In addition, turbos are far more efficient, and can be intercooled more easily (vs roots style blower). If you look at the c6 zr1 vs c6 z06 at nurburgring, the difference, despite 100+ hp advantage is almost moot. Direct from Mero's mouth, its because the zr1 has an over abundance of torque. There comes a point where exit speed suffers too much because it cant get that torque to the ground. It was the same situation with cars I built. We built an LS7 Factory Five GTM and an LS2 FF GTM and the LS2 car was faster at three of the four tracks we tested at. I just couldnt get the LS7 car out of the corner so I was using the power advantage to catch the other between turns. With the new zr1 being turbo'd you can utilize that variable timing to spool the turbo's earlier but get adequate torque in the lower rpms, then use a nicely sized set of twins to make a high hp figure, while intercooling the hell out of them. I called turbo a year ago and I am not happy the z06 likely wont be n/a...but inevitably, N/A is costly and forced induction aint. The hp/dollar factor rules. |

I would love for this to be true but it is from Feb 2013.

Not much there. |
I've heard about this for a while now from a very good source. A 427, 7.0 version of the LT1. That's what is going to be shown at Detroit in January. ZO6/ZO7 is 427 and we've seen the photos of the C7 ZR1 motor LT4 or LT5. It's a done deal.

427 NA L88! Enough said. Edit: Thinking about it though, the new LT1 is shades similar to that old L88. Swap out the manifolds to headers and you get a surprising bump in output. Not bad for a "run of the mill" standard Vette engine. I used to think the LS3 gains were impressive with a header swap until I saw the LT numbers. |

Sam, I know you love your L88s but those things ran on 103 leaded petrol and were only happy once the rpms got up high. You know today's "hardcore" hipo Vette buyers cruising to cars and coffee meets would never tolerate a modern version of that car. "No bluetooth in my L88 WTF?" :D

You just have to come pick it up!:lol: Also Skank, any idea what motor will go in the Wide Body vert we have seen camo pics of? I would assume the 427? |

Then it better receive a MAJOR bump in power cause they're using the LS7 in the Camaro now too and if its just low to mid 500HP than I call that a EPIC FAIL.

I'll go one better Sam. If skank is right, I'll be one of the first in line. I really don't see any other engine solution if they expect to keep weight within a reasonable range. The car is already at 3,450-3,500 and any FI setup will add 100lb, whether it is turbos or SC.
Jim at Pebble said to me that the car would be a segment leader in the use of lightweight composites. Think carbon wheels, brakes (a given), and possibly even suspension components to reduce the unsprung weight. We'll see. Won;t be long now. |

Skank, if you are right....I'm buying you a bottle of Crown!

The President of GM offers some clues
Car fans are attracted to speculation the way Lutherans are attracted to jello.
Here is a link to a Motor Trend Wide Open Throttle interview with the Pres. He leaves some strong hints that the future direction for Cadillac the Camaro and Corvette are going to be architected in such a way that they stay ahead of their nich competition and leverage high performance investments. |
