Al's down run was 285, his return was 274 for the record of 280.xxx  Ralph's down run was 281 with a return of 287  (289 kilo) for the final record of 284.xxx    To go that fast for that long is amazing. Congrats to both.  :thumb: :thumb:  How much of the higher speeds was the altitude and how much was the course?  Based on Al's performance I would say the course. Yes Dean, the beginning of a new era.   LSL
All motor all the time and a turbo now and then.

Ralph's two way average - 284

Al's two way average - 281

I thought that I was posting after FlaminRoo's 289 comment. I didn't realize that there was a second page...my bad..too early without coffee.

Mike Akkatiff (builder of Rocky's streamliner) predicted
 that due to the thiner air at 12,000+ altitude,
 the speeds would be about 10% faster.

Others predicted that more boost would be
required to maintain power at the higher altitude.

Both Al and Ralph were in the low to mid
260 mph range at lower altitudes.

265 mph + 10 % = 265 + 26 mph ~= 291 mph,
260 mph + 10 % = 260 + 26 mph ~= 286 mph,
so Mike's prediction looks largely correct.

Rocky reports having trouble with manifolds blowing
off in Bolivia, which is consistent with higher boost.

Picking the track at altitude is certainly better
for turbo bikes, and Rocky, Al and Ralph have
proved that fairly well.

In Track and Field, there are "adjustments"
made to the results to "compensate" for
the beneficial effects of high altitude.

They also adjust for "following winds."

If we continue to have successful LSR
racing at high altitude, will we see
the same sorts of "adjustment ?"

Will be interesting when these two bikes run Bonneville,  will give a good indication to what affect altitude/track had on their performances,,

Congrats to both  8), yes a "New Era"  :D

There was an Aprilia running Nos, they only managed 205, I expected higher for them.

Weren't they in the high 180s on motor? If so, 205 seems like a respectable gain in the flying mile.

It's not quite as fast as Joe Amo's 223 back in 2001, on a 1980s ZX10, but I think it's good :)

 I thought the Aprilia was naked as well.
Any day on a motorcycle like this that ends just needing parts and labor is a good day.

Aprilia ran fairings to get over 200, then late took off, running open class
for 190's with nitrous
 
180's NA

they did darn good

25 mph gain two way average with little N20 experience and keeping it together
after setting multiple world FIM records, is pretty damn stellar

What kind of timing equipment do they use on a track like that ?

I mean, it must be wide..

we  made the detour on the way to the US to Dual sport ride some of the country and then watch and assist where we could at the Bolivian salt , We being Jim Higgins, John Dobbs, a mate of Johns that joined us there Mick Essex and myself

The thin cold air definitely was worth 20mph if not more , but it also caused problems with crew health and bike setup
The salt was amazing, coarse, flat , and hard, Crystals are huge, making the track somewhat like a bitumen road with 40 grit stuck to it, if you wheelspin it chews tires

Timing was the std Bonneville setup with 100ft wide track  and 15 miles prepared (runs are 2 way into the same timed mile )
the bikes were getting about 3 mile run up , and at speed pretty much just before the mile
One hell of an experiance
