While these AWD UR and Heffner cars are 60 footing 1.5-1.6 on a super prepped surface like rockingham, a big cube domestic that 60 foots 1.3's will still hook harder on the street with a killer drag radial for something like a 30MPH-or 40MPH to 150 MPH race.

I still think it will be very difficult for anything with a tire that is not a drag radial with a tall wrinkle wall to have the traction to hang with these G's in any type of a street roll to be sure.

You figure wrong. Any run on the street from 20 mph up will show this beast raping the **** out them. There is no big cube domestic that 60 foots 1.3's that has the aero or the traction to go up against something like this without a launch. This 1/4 mile run wasn't even at full power. Also note, this is just the beginning, there is plenty more time to be shaved off the 60' as well as the shift from 1st to second (and additional power for 3rd and 4th). This is easily a 7 second 190+ mph car and it will go like no tomorrow for any roll

a big cube rwd car will do nothing but spin from a roll on an unprepped highway.
to be able to hook up that much power with just 2 wheels you need to be able to load up the suspension and transfer the weight. good luck doing that once you're already rolling.
its really as simple as physics...
im far from an UGR nutswinger but they are VERY good at their game, enough for me to bet 100 bucks that no rwd car will beat them from a roll on a highway.

I'd like to quote Michael Jordan, "It must be the shoes". In this case, the HRE Wheels :)

Quote from Underground Racing, "The ONLY wheel we trust at these speeds are HREs."

Thanks Underground Racing for the supporting HRE and producing some of the fastest cars in the world. UGR obviously partners will some of the best companies in the world to make sure their builds run fast. HRE Wheels is proud to be part of these amazing builds.

Congrats to every one who was involved. Simply Awesome.

Guess that answers that.....congrats UGR.

That Viper had an auto, was running big tires but only 16 PSI. That car was not making more than 1250 RWHP and it was closer than anybody expected, myself included. That is an unprepped surface and the Viper did a very good job. That Viper is a touch easier to push through the air than the G if you multiply CD X frontal area. A car like this with a little more testing is only going to get faster.

UR has raised the bar here considerably here to say the least. Like I aid earlier, it would only be a shorter race like 30-160 where a car like that blue UR Viper at the TI might have a shot. Not anything else. I am not a hater, just bringing up my points.

BTW, you may want to update your Signature now? or wait a bit long?

Congratulations. Great work!

wow sick run. maybe one day i'll get to enjoy a car like this. surprised it took a whole two days to post after heffner's run :P

Last Texas invitational, that was a brand new build driven by Tag for the first time. Viper also has drag radials. I don't think you have any idea of how fast the Stage 2 Race Versions are with drag radials.
