That looks more reasonable, so they must have seen the exception to the rule. Looks like it essentially mimics an LS6 gain with long tubes.

meengreen 94z, take a look at 1/4 mile times for a Z06 and a ZR1 and you'll find they are within about 1/2 second of each other. Now extend the race from about 115 mph (1/4 trap speed) to 150 mph and the gap gets LARGER, not smaller, going from ~1/2 second to ~2 seconds. So much for the ZR1 top end.

 

I guess thats why the ZR1 has a higher top speed by about 6 mph? I've heard before on corvette forums that they are faster on the topend(as well as more stable), but never actually seen a video/with my own eyes.

 

A Z06 has a lower top speed than a ZR1 and a base C5 due to gearing. A base C5 is also more aerodynamic than the Z06, but ZR1 isn't as aerodynamic as either. Does a ZR1 have a higher top speed? Yes. Will it pull on a Z06 at any speed below the redline limited top speed of a Z06? No.

Since we were talking about acceleration, I assumed that's what you were talking about when you said top end. At maximum speed, there is essentially no acceleration.

 

Aren't they the same car on the outside? The only differences I know of are the "side scoops" by the doors. What contributes to making the ZO6 less aerodynamic, surely these side scoops dont increase drag THAT much or do they?

 

I should have been more specific... the Z06 only comes in the fixed roof coupe, commonly called either the FRC or hardtop. Only about 10% of base C5s have the FRC body style. Almost every C5 that you'll see on the road, other than a convertible, will be the Coupe body style.

Halfway down the following page is a sillouette of the FRC body style.

I cant argue for sure on the results of a ZR1 vs. a Z06(seeing how I have no exact comparison of the two to prove it). But there are cars with way more power and topend that trap significantly lower in the quarter than other cars, but again have a better topend. Look at the ZR1 it traps 110-113 vs. a Z06's 115-118. Thats a significant difference to make up, but by the top end a ZR1 will be ahead topping out at 184mph vs. the Z06's 178mph. Part of it may be gearing, but I think also the ability of the ZR1 to be breathe better at higher RPM's plays an affect(as well as a slightly longer power band, 7000rpm vs. 6500pm)

I dont know about your comment on aerodynamics, I've read a post by a guy that owned both and said that below 100 a Z06 will outrun a ZR1 through the corners easily, but once you reach 150mph the Z06 felt unstable and the hood shook violently. On the other hand he said his ZR1 was very obviously built for those speeds, he mentioned he had changed lanes at 170mph in his ZR1 before but would never try it in his Z06.

 

 

Go race a high stall/gear car then see whos a pansy...I have no problem w/ an auto fbody/vette, plus there more consistant ifyour a drag racer.

 

I like the way newbies like to come in and act bad by calling people names. He obviously doesn't realize how much larger the percentage of Vettes are sold as automatics. I guess if someone doesn't want something exactly like him, that makes them a pansy.

And I would agree that he's probably never driven a high stall auto. Or, maybe he got whooped by one, and that's why he puts them down.

 

The best I've ever personally seen a stock ZR1 trap was 107 mph. Everybody on the net talks about 113-115 mph traps. I've never seen one come close to that stock.
