Cant wait to see what Rocky and Al Lamb can do, wishing them and all the racers good luck.

If you are there post up!!!

The Ack team will be doing updates on FaceBook

,,

Will be interesting to see what affect altitude has on their performance,,

High altitude = less drag, they just crank up the boost. I think we will see 400+

From what I've seen on-line, the salt is beautiful. Massively long and smooth.

Stainless1 · « **Reply #4 on:** August 01, 2017, 07:57:27 AM »

The bike should do well, the pack of old geezers that run it may be a different question.... I guess we will see

All the best to Ack, Rocky, Ken, Frank and Greg... good luck guys... will miss you at Bonneville, but 400 is doable on that much salt.
To bad the BLM has allowed the strip miners to ruin the Bonneville Salt Flats

Not sure if Jim (Fireman Jim) posted anything about attending the event. Fireman Jim took off from San Francisco on Sunday going to Bolivia. He met up with Greg (Ozzbooster) and they have rented motorcycles to ride out to the salt. That's all I know for now.

Go Ack Attack!

I read that Ralph Hudson and Al Lamb were bringing their bikes to try for FIM records, does anyone know if they made it? Or who else is running? I can think of several other teams that should be there if the gods of speed could write sponsorship checks

AlterEgo · « **Reply #9 on:** August 02, 2017, 08:01:52 PM »

Al is there.

sportbikeryder · « **Reply #10 on:** August 03, 2017, 07:25:42 AM »

Scott Horner n is also there

osti33 · « **Reply #11 on:** August 04, 2017, 06:53:59 AM »

Ralph Hudson is also there with his bike.

Said he's looking for something with the first number of 3.

zrxdean · « **Reply #12 on:** August 04, 2017, 10:30:38 AM »

Kickass. I hope all goes well and records fall.

That's a big jump for Ralph Hudson, but I guess if you can go 266 in 1.3 miles of dirt, then 15 miles of hard salt and thin air...

Here is a link for a report directly from the salt.

In summation: The salt is incredible nothing like it anywhere else, it is hard as asphalt. The weather is incredible; no rain, no wind, and cool. The only issue (which may end up as a huge one), no bikes either. Only 2 motorcycles have arrived, held up somewhere else....

scott g · « **Reply #14 on:** August 05, 2017, 02:37:15 PM »

Other sites report that ALL the heavy hitters:
Rock & ACK attack, Al Lamb on 1000cc turbo Honda
and Ralph Hudson 1000cc turbo are on the salt and
prepared to run - and may have already done so.

Two (2) "local" guys have run, but under 200 mph.

The "thin" air should help reduce air resistance,
but will hurt normally aspired engines. The turbo
guys should be able to make more boost, but
turbo sizing gets complicated, and does intercooling.

Just the reduction of air resistance should allow
the ACK ATTACK to go 420mph, and the move to use
6 speeds in the transmission; instead of three (3) from
10 years ago, might push the bike to 435 mph.

Should have some interesting results within 24 hours.

the aprilia running is not "local" guys

Nick Genet and his buddy are running up around 185 which is over what they ran at Mohave mile ..

That's amazing for what I'm guessing is a normally aspirated bike! Hope tomorrow is gremlin-free.

RansomT · « **Reply #17 on:** August 06, 2017, 09:12:33 AM »

(Like Scott mentioned) I can't imagine trying to figure out the turbo sizing in air that thin. The guys report that the hotel sells Oxygen inhalers for cheap and a lot of guys need it.

Ralph has a crank sensor issue, don't know if he has fixed it or not before that start running today.

zrxdean · « **Reply #18 on:** August 06, 2017, 02:29:22 PM »

For a big turbo set up for LSR, the thinner air might make the compressor a little less efficient, and heat up the intake charge a bit more, but I doubt it would make much difference. The turbo will spin a little faster to create the same boost.

Hoping everyone down there is hauling ass and setting records.

RansomT · « **Reply #19 on:** August 06, 2017, 08:46:56 PM »

Ralph ran a 266 one-way against his own 262 record, couldn't back it up due to a fueling problem. Is trying again tomorrow..

*Sorry Guys*, that is what was reported to me ....

AlterEgo · « **Reply #20 on:** August 07, 2017, 08:47:35 AM »

Maybe we will see some big numbers today. Al fastest run was 266.

joea · « **Reply #21 on:** August 07, 2017, 12:20:17 PM »

"Al" (not Ralph)..ran 266 return run
For 265 record ..bettering his 262 at bonneville

Ralph went faster over 270 approaching and entering timed mile ...then slowed

Reported that today is last day

Rocky 330 ish in liner with reported fueling problems

Aprilia 6 mph faster at Bolivia than bonneville , blows the theory out of water that
Normally aspirated hosed at 12,500 ...very cold low humidity air

Aprilia now over ...200 two way avg with a little bit nitrous

zrxdean · « **Reply #22 on:** August 07, 2017, 08:56:37 PM »

I can't find any info on results from today, and I fear that we'd all know if Ack went fast... I hope the FIA and all involved can stretch it out another day and make it happen.

Does anyone have any info about today's efforts? Prove me wrong, please.

joea · « **Reply #23 on:** August 07, 2017, 09:36:27 PM »

Ralph 289 ..Al 280 plus ..according to Mike Cook junior ..he lost connection with his dad ..not sure on return runs ..ack cam up short ...

FlaminRoo · « **Reply #24 on:** August 08, 2017, 01:12:57 AM »

289 😎

zrxdean · « **Reply #25 on:** August 08, 2017, 05:21:22 AM »

Tough luck for Ack.

But way to go Ralph Hudson and Al Lamb!!!!!

A new era for flying mile land speed records.

Landspeed Larry · « **Reply #26 on:** August 08, 2017, 07:16:03 AM »

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.

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

AlterEgo · « **Reply #27 on:** August 08, 2017, 08:02:51 AM »

Epic battle between Al Lamb and Ralph Hudson

Good stuff knocking on the door of 300 MPH!!! Its a new era!!!

SEJ · « **Reply #28 on:** August 08, 2017, 08:26:17 AM »

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.

scott g · « **Reply #29 on:** August 08, 2017, 09:14:33 AM »

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.

scott g · « **Reply #30 on:** August 08, 2017, 09:19:18 AM »

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 ?"

FlaminRoo · « **Reply #32 on:** August 08, 2017, 04:25:20 PM »

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

, yes a "New Era"

AlterEgo · « **Reply #33 on:** August 09, 2017, 08:06:15 AM »

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

zrxdean · « **Reply #34 on:** August 09, 2017, 08:40:42 AM »

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

sportbikeryder · « **Reply #35 on:** August 09, 2017, 11:48:31 AM »

I thought the Aprilia was naked as well.

joea · « **Reply #36 on:** August 09, 2017, 03:18:56 PM »

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

speedduck · « **Reply #37 on:** August 10, 2017, 10:35:21 AM »

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

I mean, it must be wide..

Oz Booster · « **Reply #38 on:** September 17, 2017, 03:19:01 PM »

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

zrxdean · « **Reply #39 on:** September 18, 2017, 11:58:12 AM »

Great trip, I would love to go there someday.

Helluva detour!
