Why is Poteet and Main going for the big prize using such a small engine?

That little engine sure makes for a mighty fast car.

I guess size does not matter after all.  LOL

Why is Poteet and Main going for the big prize using such a small engine?

My thought is that the engine can make the power needed and is much easier to control bringing the power on over the run vs. a larger engine or one that doesn't have a turbo as the power adder.  Also a larger motor might mean more frontal area?

Running over 400 is all about acceleration not just speed.  At the drag strip they manage the traction over the entire run and these guys running over 400 have to do the same.  Overpower the track and you waste valuable time peddling the car.  I think George is pretty much WOT most of the run and the computer controlling the engine, waste gates and traction control keeps the car accelerating at about the fastest available rate.  

Other cars have run and are running with probably more HP, but they can't use it all and have a harder time using what they have as effectively,

I think Rob with Carbinite is taking this to the next level with a lighter car and his variable aero traction via the rear wing.  It is going to take some time probably to get it all right but having the turbo and a lighter car that still has the potential for good traction has a lot going for it.  I'm not sure how sophisticated his computer control of the power delivery is at this point or if it is primarily his butt and right foot.  Speed Demon has the power delivery dialed in pretty darn good now.  I feel there next hurdle is going to be increasing the traction needed and possibly then needing more HP which might mean a larger motor,

As Sum sez, in layman terms too much hp and lost traction is wasted forward motion. You cannot get anywhere if you are not moving forward.

That little Dutweiler engine makes ~2500 Hp and has still room to grow, so there not short on power at all. There may come a time but for now it's all about traction and controlling it. They are pretty good at that right now but if they can get a coarse that would handle the power they have on tap now, speeds will climb pretty quickly.

The experience I have with bikes is it can be hard to get a nice controlled burn across a large piston.  Maybe the size motor they have is easier to tune.

The experience shows that Dutweiler doesnt suffer from tuning the combustion process across the  top of large pistons

The BUB 7 entry is listed as "Jans, Harralson"
What happened to Denis Manning?

Denis has had it for sale, so its possible that it got sold.

Lots of rumors floating around.
