Anyone with a regular C6 ever race against an older ZR1? What were the results?

Im curious to know as well, Im assuming major whoopage.....

Not as major as you would think , a ZR1 with a good driver will turn high 12's as opposed to the mid-12's of a stock C6 .

Hmmmm. Interesting. I would think the C6 would be able to consistently beat the ZR1--drivers being equal.

Why would that be? Both cars have about the same power.

It does and it has. I remember Vette doing a special a few years ago. a 91 ZR1 vs a C5 Z06. The C5 Z06 easily beat down the older ZR1.

LS2 C6 should have no problems and a ZR1 shouldn't even bother an LS3 owner unless he wants to get smoked.

The 1990 ZR-1 Is all i ever hear about "King of the Hill"

It's definitely worth alot more then the average C6

Funny, I've seen ZR-1s smack C6s at the track. I would like to see the "get smoked" part against a ZR-1 - even a stock one. I really would.

I would hope so. The MSRP price in 1990 for a ZR1 was several thousand more than the MSRP was on my 2006 coupe - non adjusted dollars. I hear dealers even got as much as 100K from desperate buyers. Deja Vu.

And the ultimate irony is that the LT-5 remains one of the most advanced engines ever put into a production Corvette, to this day.

Mechanically the LT5 is a much more sophisticated engine than even an LS7 or LS9....variable valve timing etc. It just doesn't put out as much power.

I own a C6 ZO6 , 1991 ZR1 stroker and a 93 ZR1 LPE stroker 385. All different beasts. The ZO6 can keep up with the LPE car. The 91 will clean out destroy the ZO6. But that isn't fair. A stock C6 against a stock ZR1 it's a drivers race. Cant beat the technology of the C6 , it's light years ahead.

C4 ZR1s aren't really quarter-mile burners... they pull super hard up top and really show their power after 100 mph.

I disagree while the LT5 had DOHC that alone does not constitute advanced engine design. I'm not arguing that the LT5 is not an impressive engine, just that the modern LS2/3 engines are superior. Consider that the LS3 can get 30 MPG, 10k - 12k between oil changes, produces more power, and they do it all with only one cam.

The ZR-1 was rated at 375hp. I dont remember what the torque rating was but I know it came on higher in the powerband due to 4 valve heads. Stock for stock a LS2 or LS3 will walk it.

In 1993, it went up to 405 bhp.

Early ZR1's only had 375HP, then it went to 405HP. The ZR1 (C4) did weigh a little more than the C6, but not by much. I have driven a 91 ZR1 and a 96 Grand Sport, the ZR1 did feel a little stronger, but then again, they both feel a little stronger than a C6, but it's all about the "feel". I know my MN6 Z51 C6 will take the checkered flag, but not by as much as you think!!! The ZR1 was and still is a bad SOB!

Stickboy97

Wrong, Considering most of the ones I see are $30k or less they don't hold their value at all. Many of these vettes were sold for more than double that. Not saying a C6 will hold its value either but these cars lose it just like all the rest.

Thanks, I forgot about that. My buddy had 91 375 version.

I never said anything about its overhead cams being the reason it's so advanced. Read up on it - the LT5 has more race engine heritage than almost any other engine GM put into a production car. It goes way beyond the cams. Mercury Racing actually built the LT5 - by hand, one at a time.


Fast forward almost 20 years from the LT5 and I would hope their would be some improvements, though if the LS2/3 had some of the virtues of the LT5, it would make a lot more power.
