That website is full of goodness. It's nice to see proper racecars. :thumbup:

With increased advertising space! We NEED that!:)

Oooo, DeltaWing engine choice coming soon! Gotta be a Honda/Acura thing, wouldn't you guess? Shake 'em up, go Cosworth Mazda!

[Trevor Longman]

Come to think of it that Cosworth Mazda that was run in the Swift 016a Atlantics car for its last few years would have just about the right amount of power they were looking for in the Deltawang

You are CORRECT, sir!;) Hmmm, how 'bout a rotary? Mazda isn't entirely unaquainted with LeMans. Wouldn't need 700 (?) hp this time.:)

I've always liked the rotary, and I still have my Revell rotary engine model from the '70's, but with a fraction of the development of the piston engine, it's still a fuel pig, so it wouldn't work well with the D Wang concept.

A turbo Hayabusa would provide more than enough.

For a little while.

For a little while.

As in go "boom" before 24HR?

Yuppers, way before 24 hours.

Have the same concern about rotary mileage but isn't it possible with the weight savings and improved aero the advantages in rotary balance size and power might trump mpg or at least make it less a concern? Doesn't have to be that big ol' 4-rotor ya know. Just hoping for a surprise BEHIND the driver, too!:)

They certainly could, but it would detract a little from the point they are trying to make if they chose an engine which is a bit thirsty. They could use a little 1.5L turbo four banger. It would be bigger and probably weigh at least 30LB more than the rotary that could do the job but then they could go farther on each stint.

I do wish the ACO would let rotaries back in. The air restrictor would deal with any supposed horsepower advantage, it has its fuel economy disadvantage, and we could see a bit more variety in approach on the track while Mazda (or anybody else), works on further developing the concept.

ROC tried the lightweight turbo four at LeMan using a VW engine. They were quick, but they all blew up. I don't remember what year it was. Kinda stressful to push the output of a little motor that long.

The little AER Mazda seems to do pretty well for Dyson, although they only use it half that long, but that one is cranking out twice as much HP as the D Wang would need.

Dyson says the Sebring motor stayed in the car for Long Beach, so it was 3/4 of the way there, with a more demanding sprint race for the last 1/3 of the hours.

Turns out I can't add. :gomer: It went once around the clock and then 1/4 around, so it's only 15/24ths of the way there and only the last 20% was under sprint conditions. :gomer:

Still, in a much smaller car, it would be equal to the task. Getting a Lola to the finish line might be another matter.
