Are you abusing your car when doing a top end MPH?
<strong>Racehead, if you are in doubt, come over here and take a ride with Roy. I would say with me, but I'd probably blow up the engine again, so go with him and he will show you what you don't know. Don't be afraid to know less than someone else, because you always will. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Jack,
You can't imagine how much I would love to do exactly that ! I love to go fast and would be perfectly willing to go for a ride with Roy on the autobahn if the opportunity came up. Being afraid to know less than someone else to me is like being afraid of the Bigfoot. I've never seen one, and don't really believe there is one, so it'd be hard to be afraid of it. lol !j/k If his car will go 160 mph in 6th gear then there is a reasonable, mechanical reason why this is so. I'm waiting for the explanation . And no, a heads and cam combo is not going to accomplish this. Maybe 4.10 or 4.56 gears might do it . This would also explain why he's burnt up 2 rear ends and trannys <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I'm just waiting for the reason why his car will do it, and I haven't heard it yet.

NataSS Inc on the board is running the 160? class I believe, and then moving up to the 180 class next year.
Roy, though, never said he did 160 in 6th gear. He was probably talking about WOT in 6th gear, which is about 130-140. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
<strong>180 miles per tank at WOT, are you crazy? I rarely call BS on ls1 boards, but I have to here. On the road course, my old '98 Z28 consistantly got 7 mpg, which would only be ~98 miles with 14 gallons (our cars have 15.5 gallon tanks). On the road course, I was not wide open all the time, and the wind resistane at 160 is going to really hurt mileage. FWIW, I get 180-200 miles per tank on the street. Yes I drive fast, but not 160 for 200 miles <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Exactly what you said, at last May's Silver State Classic race I averaged about 7 mpg . This is going 160+ mph for about 50 miles, 130 mph for the next 20, and 105 mph exactly ( on cruise control ) for the last 20 miles. I never left 5th gear the entire race. Our cars get absolutely amazing gas mileage for the power they put out, but if you're running wide open or close to it, then forget about it. Your fuel economy goes out the window <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

As far as the fuel issue. In May I ran in the 145mph class with a 165 tech speed. at the end of the run we had a little over a 1/16th of a tank left. I think what might have caused the large fuel consumption was some of the wind we were fighting. But last weekend we finished with a little more, I feel because we didnt have as much in the way of drastic throttle movement. But trying to run 180 miles on one tank at WOT....aint happenin, and I will have to see video to believe it or be in the car when it happens. Not sayin it isnt impossible but would be tough to do.
