No doubt it's wicked fast..

Can't help but wonder what mods that guy has on his car though. Is he on street tires or slicks?

Considering he is in a nomex suit and has a viper club plaque on his car, I'd assume this is not a showroom stock Viper..

So are we comparing apples to oranges?

Impressive regardless though..

Not bad performance for a pickup truck engine. Good company for the Triumph TR2 that was powered by a Ferguson tractor engine.

We know the rev-limiter works.

Sometimes it's quicker to bounce off the rev-limiter than it is to up-shift.
If you calculate the upshift time, then the immediate downshift, it's often better to stay in gear if the turn is coming up..

And that doesn't even include the potential errors, miss shifts, bad heel n Toe, missed rev's, etc. that you can possibly have by trying to cycle gears too quickly.

My point is, yes, I did cringe when seeing the driver bounce off the fun limiter but I also understood his technique and thought it was probably the fastest way around the track, despite being bounced for what seemed to be a few seconds.

You're right but a few instances I though it was a bit much. Most of the time in the tight turns a shift would have been costly and inefficient. You have to admit a couple of times on some of the long stretches he could have utilized the torque of the v10 and not bounced the limiter.

Ok, watched it again..

First, we don't know how the car is geared, but every time the driver got in or near the rev limiter he was almost immediately in a moderate brake zone.

And on that long stretch on the back of the ring, he seemed to be maxed out in top gear (as I said, gearing is most likely not stock)

To risk an upshift for a second or two, then to drop back down with a monster blip, heel n toe, could easily send the back of that car chirping.

Smatter to ride the rev.. and faster... Less chance for mistakes, not enough time to be able to capitalize on the upshift before the braking zone.

At Laguna Seca for example, coming out of the corkscrew, I'm grabbing 4th gear preparing for turn 9, right before the bridge. And I've only just gotten into second. It doesn't sound right, it doesn't feel right, but it's right....

The driver clearly knows the ring and stayed in gear for the right reasons.

I'll yield to your expertise and that of the driver. I did not even think that the Viper was redlining in top gear on the backstretch. I figured it had one more gear and was not doing 190mph at the time.

Anyway...I'm going outside now.

B's right. The car's geared just a tad too short for this particular track.
