ANOTHER 500 MPH CHALLENGER!?

[1leg]

The critical questions . Will it have traction control and downforce ?

This car will be Throttle By Wire using motec. In the video Steve says the driver will put foot to the floor and steer the car. The Motec computer will control everything else.

Lot of cool tech in the most recent engine video. Cam sync gizmo seized breaking cam gear etc. Only got it up to 3000+hp. More to come. Watch it suck the intake closed. Yikes!

     Heck if its that type of power control system the driver is really there just steering. Heck why put anyone in the car just stand along the return road and control the car  with some type of hand held controller

Going really fast is simple but impossible without the right combination .

Peak traction is just before wheel slip . Drops off when wheel spin begins  . Preset waste gate in each gear by trial and error . Like skating on thin ice . Sensing wheel slip / ice break through is too late . 

Eric Ahlstrom told us that downforce from wings or low pressure beneath the body are equally efficient . Wings can be maximum downforce at medium speed . Moderated at high speed .

[SPARKY]

my guess is that it is using the wheel humps for down force at speed and they look equal size so I would guess 4x4.  I am guessing a bottom that sucks also

I think that Steve Morse also mentioned that they have a 10 speed gear box. That with all of the control electronics is going to make this car a non stop challenge to keep it running. The Poteet crew were a great example of what it takes to be successful with a high tech car. They made lots of run, they had a professional crew and everyone of them knew their job and were very good at it. They were good to watch when they came to the starting line. Not much was missed although I did talk to a couple of their guys that said on the 487 mph run there was a programming glitch that caused the car to be in traction control mode for 13 seconds, i.e. not WFO, which could have possibly kept them from a 500MPH run.

The opposite of all of this high tech tomfoolery is Danny Thompsons car. No turbos, mechanical fuel injection, horse power controlled by nitro percentage ,minimum electronics, 3 speed transmission and traction control by Dannys right foot. On his last run he was almost 460 out the back.

Alot of what is going into this car was leveraged from the technolgy used on the Speed Demon but are going a little further with even more $$.

I sit here wishing it wouldn't have to use traction control, But i'm sure sitting inside with a turbo motor making north of 4000hp going over 400MPH. I would be glad it has it.

I'm a fan of Reg Cooks Kiwi Can Do streamliner He has incorporated the best aspects of the Speed Demon and Danny's car. First off his engine is turbocharged and is easily controlled as such. He has 4 wheel drive for the best traction and last, he has a very aero body shape that is very reminiscent of the Thompson car. To Rex's point he has a large qualified crew and a chassis dyno that will be on site. In the rarified air of Bolivia the turbos will make the necessary HP and the long course with little concern for slowing the car like the T550 has will work in his favor. I don't think he'll have any of the licensing concerns that the T550 had this year either. He has just acquired a bunch of tires and I don't think the fuel will be an issue this year. Truth be told, I'm a fan of all the over 400mph streamliners, but think the thin air at 1200 ft elevation could be the determining factor for a 500mph timing slip.

Question for everyone? Sounds like the computer on this car will handle the total control over the acceleration of this car. If that is indeed what it does, is it time to give the red, blue or black hat when the record is broken to the computer guru? Seems to me they are the one who is truly responsible for the outcome of the run and not the driver who is along for the ride.

On Danny's final run he got crossed up and out of the throttle for 5 seconds . If not for that the last mile average would have been maybe 470 .

The Garage Shop crew are all former Nascar people.  I believe they have the crew part down.  Money with the sponsors doesn't seem to be an issue.  And, they have no issues spending days at a time in A2 wind tunnel.  I am excited to see. 

But.....want Sid to pull it off this year

I don't believe anybody has ever gone 400 at their first meet so that in its self would be a huge milestone. About 380 is where it starts getting a lot harder. We spent a lot of time with Betsy in the 380 to 400 range before we cracked it as did Nolan back then but SCTA didn't allow traction control at that time & engine management was selecting the right pill without burning it down. Then there was the old "qualifying run - down run & return run" for a record that separated the men from the boys! That's something I believe even Speed Demon has never accomplished.

Goldenrod only ran in 1965 and went 400 on their 5^th pass?

Not quite the first meet but mighty impressive.

[PorkPie]

5th run....well....when they was back in November....

the runs before wasn't that successful....the Hurst shifter was a troublemaker and the big dent in the nose due to the airpressure was also an issue....

Bill told me the whole story.....

Danny Thompson was the last piston engine driver in the old tradition...like Summers, Teague...a.s.o.....traction control by right food.....
