What have we learned from the 4 cars that have just gone 400?

[Caveman]

It may be possible that the track length and salt frictional coefficient does not allow speeds beyond the 400's at Bonneville. 

No problem. Just add downforce and horsepower as required.

Well, with salt mining leaving the surface thin, and a couple of trucks/rigs breaking through each year, the ballast & downforce part of the equation has a limiting factor somewhere....  just don't know how close it is yet.

what about stopping, I wasn't at the shoot out, But it look like the 400 mph cars were slowing down easily and pulling into the pits to a stop. Others in the past ended up in the mud. Are the parachute designs better now than then? Did the 400 mph cars this year use more than one chute?

They ran on the international course that offers more distance. Only one measured mile and kilo. The international course runs past the paved road in giving them the extra length. They used chutes as well when needed. The highway end is closed off for runs in either direction. With only a few cars and one bike it is easier to control the traffic. I hope this is clear.

crystal clear thanks. I was thinking there had been others in the past that ended in the mud other than Summers Brothers on the international course. So I thought these 400 mph cars, bikes were stopping quicker with more control. Hard to judge from here.
Thanks Rick

FYI, the AA motor in Spectre's streamliner makes 2100hp at 21psi of boost, and runs a pair of Pro Mod 91 turbos direct from Harry Hruska at Precision turbo.


The car is deceptively simpler than most people here understand; most of the guys have no streamliner experience, but they have great attitudes, teamwork skills, etc.   The FAST EFI system on that engine is the very first EFIsystem the engine builder has ever used - that's right, he's a first time EFI guy.  (Courtney IS smarter than the average bear though!)

I worked on the project, in fact I think I started a build thread on it back in 2007.  Great group of guys, I can't say enough good about the Spectre crew,


Also, they do not use traction control.  It doesn't work like everyone here *thinks* it does.

Hey Geek , wasn't the fastest car at the shootout carberated?

he had a tailwind

And nitrous

thanks, needed all the help I can get!!!


(johnbeck guided us on our Engine Masters CHallenge entry this year, and he has a carb that beat my best EFI efforts by .5 average hp from 2500-6500rpm, although I out-peaked him by 1.5hp).  I basically owe johnbeck lunch for life     absolutely great guy, if anyone in northern CA needs a truly competent engine & dyno guy - get your A$$ to ProMachine.

[johnbeck]

Thanks for the kind words Geek , but lunch is still $15.oo at Logans

Don't forget about morning thunder guys for a great breakfest.

The breakfast food there is definitely very good.  But it's not the primary reason I go there

haha me either
