Texas tuner John Hennessey's work on big Detroit iron has its acolytes and detractors, but the man knows how to show off his wares. To highlight the top-speed performance of some of his big rigs, Texas authorities let him take a full-speed blast down the state's newest toll road outside Austin that opened today, one that features an 85-mph speed limit. It's just long enough for the 1,200-hp, twin-turbo Cadillac CTS-V coupe to hit 220.5 mph.

Hennessey told Jalopnik that the stunt came about after a conversation with state officials and an offer to test out a toll tag system to see if it could accurately report fines at triple-digit speeds. In addition to his 1,200-hp CTS-V coupe, Hennessey also brought a 707-hp Chevy Camaro ZL1 that managed to hit 203.9 mph along the same strip, with an even better sound. Hennessey says the CTS-V might have done 230 mph had he been granted another mile of tarmac.

And for the record: All of the electronics used by Texas state officials, including their radar guns, worked perfectly during the run. Word to the wise: 85 mph will probably be fast enough.

That's 3.5 miles per minute. Or 308 ft/sec. Or roughly a football field per second. In a car.

^ This just about sums it all up!

Yes there's an emergency! My eyeballs are now behind my brain!!!

I read that one today as well, crazy folks over at Hennessey...

I dont think so, that was the point of the test. They have high speed cameras to take pictures of speeding cars. There were able to get a picture of the VR1200 while it was doing 180mph [race] At least thats what i thought they were getting at by having Hennessey out there

If they do it with speed cameras, most folks will learn the position of the cameras, slow down when approaching them, and speed back up.
If they do it with a point-to-point system that takes the average speed over a certain distance, then I can see it working.
In any case, there WILL be folks pushing 100+ mph on that road. Whether or not they end up paying for it will remain to be seen.

But I don't think many commuters will be doing 220.5 [:)]

I think it was smart of Hennessey to convince the state of TX to allow them to do this for camera testing purposes. Great marketing campaign for them.

Definitely, three of my coworkers were talking about it today on their own when I joined in on the conversation.

thats crazy...

Great marketing campaign for them.

You bet..... ^

I think its pretty awesome that they were able to do that. Great advertising and may convince folks to not speed the whole time.
