LS7 twin turbo finished

[XcYZ]

Jeff, what do you think of running the Hoosier R6 on the street? I've heard that after a few heat cycles they get hard. What's your opinion?

Frankenstang:

Let me guess, 150k-200k should get someone a pretty nice one. Less if it is used.

Is this pretty close? (Rolling chassis 89k)

Total cost about $250,000 as it sits now. This started out as a (Ultima Sports UK) factory built gen 1 powered car, not a kit or a roller.

================================================

Thanks for info. At least I was starting to get in the area price wise.

The car looks great. I'm sure you are very proud of it. (I would be)

Thanks for posting the links to the videos. Me and the rest of the "Arm Chair", Ultima Drivers appreciate the view.

Do you have any from that run from the inside of the car?

Thanks again.

Anyone notice that when that thing comes up and past the camera on the run, you don't hear it until it passes the cameraman?
I had no idea a car could exceed the speed of sound!

After a few track day heat cycles they do get a bit hard. Then it takes more heat before they work. But, if you only ran them on the street chances are you'd never get them hot enough to damage them. Unless of course your daily comute is angels crest highway in CA. I like Pilot Sport PS2, for something more hardcore I'd put Pilot Sport Cup. In the case of this project, he wanted 15" brakes which require 19" wheels and the Hoosier was the only choice for this application, due to the low profile and relatively small diameter. We still had to radically alter the wheel well area to fit them.
thanks

Jeff what is the size on those Hoosier 19" ? My car ran 19" in the rear originally back in the late 70's to mid 80's when it ran in IMSA but there have been no tires for the car for years.. it had 19x14" rims. Wonder if these Hoosiers will work.

over 1000 HP ! Wow.. I just dyno's my flat six , 3.2 liter twin turbo motor yesterday and made 720 HP ... but 4 digits would have been nicer

[frankenstang]

345/30/zr19 from what I remember. It would've been nice if they made a 20 series tire. Never get them on the rim though. They did look like steamroller tires without the clamshell on.
