I just realized that the long runner Webber carb combo is equalling
the
hp (at 6000 rpm) of the Lemans engine with tuned intake.  I'm having
understanding how this could be possible except that your runners are
slightly smaller i.d.  than the LeMans and therefore more efficient at
lower rpms.      Jerry


Not true. Take a closer look.

The Lemans engine generates 240 HP at 6000 RPM and ours is only
generating
226 HP at 6000 RPM.  I expect a bit more when we get the EFI working
with the slide throttle due to the manifold pressure loss we are
experiencing with the carb. I don't expect to EQUAL the Lemans
engine precisely because our pipes ARE a bit smaller.

Paul,

"Only 226 HP at 6000 rpm" is within 6% of a full blown race engine (per
rotor) on essentially the first try.

Pretty impressive for a basically stock engine using some off the shelf
parts.

Also an excellent starting point.

Thanks Steve but we cheated. We copied the Lemans engine as closely
as we could.

BTW for the new people the Lemans engine ran for 24 hours
using this full throttle engine speed distribution for the RPM. It
spent 28% of the time between  7500 and 8000 RPM. They disassembled
the engine after the race and could not measure any wear.

Also BTW the Lemans engines is no longer considered a full blown
race engine as some people I know are running them only between
8000 and 10,500. They start were we leave off. The turbo race
people are getting as much as 400 HP or more per rotor.
