So is there any video of the Gold Rush and Cheetah world record runs? I'd love to see them. How about the old Vector world record run?

I have a giant pile of tapes from Marti Daly but haven't had time to review them. I sure there is "gold" in there somewhere...

Marti was the pres and archivist of the IHPVA for many years.
Probably a better place to ask would be the IHPVA directly.

Frankly speaking, I doubt any footage of the record runs exists of the Vector or Gold Rush. If it was done it surely would have been part of any museum exhibits they have been in. I've seen both in several displays with no footage.
The Cheetah was on CNN.

That is disappointing.

Among other things, this was one of the goals of the .deciMach Speed Prize. Gather the contestants at one point each year so everyone could learn together, rather than each team wandering off into the wilds to their own little race location..... And to take LOTS of pictures/videos ;-)

Just curious what kind of run up to the 200 meter time trap did the Vector, Gold Rush, and Cheetah have?

I looked through the VHS old tapes, and hooked up a dusty old VCR to my equally dusty old TV. There's some good footage. I located a CNN broadcast of the Cheetah and there are many semi-professional IHPVA championships tapes from the early '80s and '90s. They mostly seemed to focus on the oddballs, but I caught glimpses of vehicles from Easy Racer, Weaver, and Barlow.

Hey Al Krause, what are the legal implications of posting IPHVA videos on YouTube?

Now I need to find a decent USB video adapter.

Vector raced on the 2.5 mile oval Ontario Motor Speedway, since torn down. I assume the faster riders had roughly one lap (2.5 miles or maybe 2.375 miles depending if they didn't want the trap start/finish to overlap the launch area) to get up to speed. I don't know - I wasn't there - only a kid at that time. Some other events at that time, used a 600-meter run-up followed by the 200-meter trap, because long courses were hard to find. At some point the IHPVA slope requirement of 2/3rds of one percent maximum came into play based on the slope at Ontario or elsewhere. This course was listed at 301 meters elevation.

Gold Rush at MonoLake I believe only had about a 1.8 mile to 2 mile run-up. Fred really had to push it from the start to get the record. 1524.4 meters was the elevation of this course.

Cheetah I think only had a short 2.5 mile run-up as well on the course near Alamosa, Colorado I mapped what I think was the course here. It looks like they could have used almost a full 5 miles like at Battle Mountain. http://s47.photobucket.com/albums/f152/uprightmike/Alamosa%20Colorado/ 2438 meters was the elevation of this course.

Wow, those are really short run ups compared to Battle Mountain. I wonder what the Vector and Cheetah could do at Battle Mountain? Didn't Gold Rush run at Battle Mountain?

The Double Gold Rush ran at Battle Mountain in 2001 and 2002. Fred Markham and Chris Springer did about 68.91 mph in it for a Tandem Kilometer Record. The same two guys had pedalled the Vector Tandem 42 miles down a stretch of California's I-5 freeway at an average speed of over 50 mph in 1980.

Warren - you have a treasure trove! I remember when Marti gave it to you and Sean in the parking lot at Indy.

Ok, here's the first video - from a 1992 CNN science show, of the Dexter Hysol Cheetah 68 MPH record.

http://www.youtube.com/watch?v=LDA--6viq54

I'll go through the rest of the videos as time permits. I may end up with a "best of IHPVA championships, the early days".

Excellent job Warren, going back in time to do those interviews, editing the "footage", and putting together one, nice package.

Maybe edit the last comment to note that Sam broke the record in 2000 at 72.74 mph when you get a chance.

I still think the Mango looks like a 3/4 scale Cheetah.

That's how I see it as well. I didn't realize Chris Huber was 6'3". Wow. Did the cheetah designers really think that 68.73 mph was the ultimate in speed? LoL! I wonder what they thought when they heard that Varna went 72.4 mph? Really neat video. Funny, I'm about the same age as the Cheetah designers. But I really never heard of HPV racing until about 1992.

I was there- I was 16 years old at the time, and barely able to drive out from South Pasadena on my own.

IIRC, the Ontario run-up was at least a full lap of the oval, if not more. There was room to start on the pit straight and then go around to the traps near the start/finish line. I think.

The next year, at Pomona, had a very short run-up, and I'm pretty sure the track has a slope to it.

Adam- I, too, would like to see the Vector and Cheetah run at Battle Mountain. The length, good surface, and altitude would surely allow them to beat their existing marks.

Great video! I love how in the early days of HPV racing people were experimenting with all sorts of rider positions, frame configurations, and fairing shapes.

The CNN video has a brief clip of a Cheetah tuft test. The tufts show an interesting flow. The flow seems laminar on the sides (except near the windshield) but turbulent at the tail end.
