No Magnetic Suspension In The 14 Z/28?

[Unreal]

I think the over 500ft/lbs is a typo. LS7s make ~440 torque. No way they got 60+tq out of it.

It does have adjustable dampers...

That's the 2nd time I have seen it so I guess we will have to wait until they release the final numbers.

That's for SCCA classes except for this:

The Chief Steward must approve the proposed classification. He will not approve if the car is so dissimilar or the car/driver combination otherwise unsuitable that it is a hazard or impediment to fair competition among the other cars in the class and race group.

I believe the Corvette participates in the Grand Touring class. Not sure which one though.

I don't buy the rough ride idea. I guess everything is relative. Not doubt my '69 Pro-touring is a rougher ride than the '14 Z28. But, it's not like the 69 is an uncomfortable ride. Maybe people are getting soft these days. I'd buy a Z28 in a heartbeat if hadn't just purchased a ZL1.

Correct, however with 12.5:1 compression, direct injection and cam profile similar to the C7 (450-hp, 450-tq estimated out of 6.2 L) it would be possible (particularly with long tube headers and 3" exhaust) at the flywheel.

No mention of this for 2014 however but for a 3,800-lb track car 500 lb-ft of torque is a useful target to have since that is what allows the ZL1 to have better lap times (most tracks) than the GT500 by using it's superior traction to lay down the torque to generate higher corner exist speeds.

From:
http://www.chevroletperformance.com/...2397&engCat=ls

"the LS7 uses a 7.0-liter aluminum dry-sump block, CNC-ported cylinder heads, and titanium rods and valves to pump out 505 hp and 470 lb.-ft. of torque."


30 lb-ft could be gained with CAI, low restriction exhaust and tuning

[madmax13]

The shocks are 4 way adjustable. Tuned for both high speeds and low speeds. So it is entirely possible that it will ride decently on the street....

but it is a racecar so who cares!

Yes 470 TQ! I believe the intake and exhaust have been modified for the Z/28, so the comment of over 500 is possible.

Just for fun...what performance difference would A/C make?....Perhaps as it is an option, just wondering if it would be designed so you could by-pass with a different belt or whatever if desired...

....Some may want A/C for street use, but not want it for their track days and have a power loss...???

[2cnd chance]

If it's off doesn't it freewheel? It will add some weight to the nose though. I can't imagine you'd see much difference in lap times with it off.

...That's what I don't know...thought even if it was there it would be a "drag"...lol...even if off....

People are whining it doesn't have heated seats or a nice stereo. Lots of people just don't get it and never will.

It's not so much the loss of power - but how much extra weight adding A/C would be.
