Mecca of Speed

I looked at the area on a sat map just now, wow, i never realized how big the area is.

was that ford truck they used a big POS? it was smoking like it was hauling 15,000 lbs when it really was probably pushing 3k at the most.

that helicopter had the best view. it could actually see the cars at speed close up. did they get any video of the bike?

Yeah, surprisingly much. Lots of people stopped by to see what we had and people in the next class up who are VERY serious about their record setting were impressed at the rookies I think. We saw the guy who's record we broke the morning we were backing it up and he seemed surprised. He told us his partially streamlined record was very hard to break and that we shouldnt even be attempting to break it. We came within 1.5-2 mph of it and with his aero fairing instead of the factory one we were running, we would have broken it.

Speaking of which... I checked it out on Google Earth a while back.

Here's the mountain behind our motel looking towards the Salt Flats to the East. You can see the service road coming up the left (north) side of it. The red mark is where we were standing.

Here is the view toward the Flats in Google Earth and real life from that same spot.

Now that I think about it, I think the helo was there filming the Ford Fusion hydrogen powered 200 mph car. I didn't see them filming anything but that actually running.

Grayson, name them.

49 Ford in the first pic.

second one is a hudson, 48?

last one kinda looks like a lincoln.

Anything newer than 39 and older than 55 I am always just guessing at.

what they said. last one is bad ass!

so you are saying you could have set two records?
Note to self: bring aero body kit next year to set two records instead of one.

did you do the math of what it would take hp vs drag coeficient to get those 1.5-2 mph? is there a rule of thumb kinda deal for hp vs frontal area vs drag. kinda like 1 sq in = x hp @ x mph? I was never good at numbers, just ideas :D

also is it true that a flat front w/ rounded corners is fairly aerodynamic? vs. just square. my Dad always said that the stude lark was fairly aero for as boxy as it was b/c of its rounded corners all the way around. do the corners make a huge difference?I think the factory R2 (paxton supercharged 289 ci) cars did 132-140 mph in 1962.

We could have set 4 with a little more than a month of preparation. There are two aero records, fuel and gas, and the same two non-aero records. We set the non-aero gas record and didnt have time to go for the non-aero fuel record because we tried for the aero records first.

I left all the calculation stuff to the PhD. I just built it, but yes he did all that.

Corners do make a big difference. They allow much less separation of the air. You can look at separation as a vacuum pulling back on the car. I would get more into it but I've got a math quiz to study for...
