Max race speeds?

[zeke]

What do you think is the max speed achievable for an unlimited?
Not just a short sprint but continuous that could be held until the fuel tank runs dry.

Like in a jet most are mach .8-.9 unless with an afterburner (F-22 & a few others excepted), so top speeds of mach 2+ were very rarely obtained unless for a few minutes.

What would a racer (or warbird P-51/Seafury etc) be able to do without nitro, ADI, water sprays etc.

The current upper limit being about 540mph (Dago & Rare bear) for short bursts with all the magic gear, without? maybe 400? more or less?

In a race like the old Cleavland or Mojave races, what speeds could be held?

I would say about 320-350 at sea level for a completely stock mustang right out of the factory. But Dago or Strega with a stock engine could probably go 400.

Thanks, I've been curious as to how much a benefit it would be having a stock airframe with a race motor or the reverse in having a fully race prepared airframe with a stock motor.

They must be some slick Mustangs, would there be the same sort of benefits (aerodynamically) on the large radials with all of their frontal area?

Re: Max race speeds?

Ryan is correct. 61 inches of manifold pressure and 3000 rpm out of a dash 7 with 9 heads and banks a speed of 325-335. Ryan, next time you see Jimmie, call him 'Jukebox'. Nothing bad, but sortta funny. He will know who you have been talking to. ss
