Top Speed....governed?

About 170 is where acceleration drops to zero, at a little above 6100 rpm in 5th. Nothing more left to give.

Not sure how much faster or what she had left in her, but she was definitely screaming! Sure felt good and seriously got the heart rate up!

my 1le felt very grounded at 155...honestly, as I recall, I probably would have guessed I was doing half that from road-feel (but I did have the windows down, so quite a bit of wind/engine noise to remind me). I'm curious how a zl1 feels at that speed in the different suspension modes

I was just going to say that the 188mph someone else posted was a bit overboard.

The one thing I miss about my 4th gen SS, top speed 165mph. Kinda scary though lol

[djnice]

I had the 4th gen to 150,
5th gen SS to 150,
and the ZL1 to 160.
All on the same road.

The SS was a little more planted than the 4th gen. In the ZL1 it is incredible how the down force keeps it planted.

Yeah, 184 or so is the ZL1. Not sure about the 1LE. It would be interesting to see them on the same straight stretch.

[OzzySS]

that was me...guess i was thinking of the zl1 there. oops. like i said in the original post, "could be wrong"

[Michael2000]

I posted the same questions, since the 1LE has the same tires as the ZL1, why it doesn't remove the governor. Someone responded that the 1LE doesn't have the ZL1 underbody aero pieces.

I really haven't had the opportunity to let her go yet, always something, like other cars on the road or very windy. Conditions, conditions, conditions, very important. A hard gust of a crosswind at a buck and a half will make you change lanes unexpectedly, in my SS. The ZL1 is rock solid, but like I've said; the opportunity just hasn't come up yet. I've had her in the 140s dozens of times, and the low 150s a few times, and she still had plenty of juice. My goal is the 160s next, then maybe 170s if she feels planted solid. I think 153 in the SS was about it, didn't like that floaty feel at all, and the conditions were perfect!

Ezra Dyer a journalist took an SS to the salt lake flats. He did just about 175mph.

I think the 3.91 gears of the 1LE are going to lower the top end a little bit.
I could be wrong since the limitation was drag and not rpm.

This is my buddy TripleblkZL1's ZL1, I'm the one filming. Did about 165mph this pass. Felt planted and smooth as ever. Still had a lot left in her.

(also incase you can't tell, this is a closed course airstrip)

Sweet!

Had some left.... not much... it was planted and stable.
