yes, that's the newer V8 engines and would be even better though more $$. I
was referring to the earlier engine in the 540's.

That will definitely be a great setup, though your friend will certainly be
much lighter in the bank account.

Re: More New Scrambler Details
its the magical BMW 286 bhp thing again !
Lets see now:
the '85 635 CSI had a 3.5 i6 ,
the '89 840/540 to which you refer has a 4.4 v8,
the M3(E36) of '93 had a i6 3.0,
each of which produced 286 bhp !!!

5.5psi stock, 11.5psi with race fuel or at altitudes above 5000ft with
92 octane. Oklahoma is too low to run 11.5 without water injection and
Bilouxi (keeser afb) is almost too low to run at 5.5.

Roots blowers don't heat the air near as much as vane types do.
Take a feel of almost any vacuum cleaner exhaust. That heat is mostly
due to the inefficiency of the impeller.

5.5psi compression of air at sea level increases temp by... (where is my
thermodynamics book?) ..search.. ..search..
Ok.. that would be about 150ºF increase for ideal where a vane type
with about 65% efficency would be 259ºF increase.
There just isn't room for an intercooler with my setup. Water injection is
the only viable alternative. I am thinking about bringing some cool air
back into the engine bay or installing the hood vents from the 5.9.

Yep.. only problem is space.
Pics are on my site.
This is the casting that adapts the blower.
