4.0l HO is 8.8:1 actually :) I stuff another 5.5psi into it with
just the stock pulley. Any more and it would need intercooling or
larger injectors.
I use a eaton, roots type, blower, always turning even at idle. The good
part is it doesn't heat the air near as much as a vane charger like the
paxton does.

Re: More New Scrambler Details
wow you run a non intercooled setup? how much boost aqre you running? thats a
nice compression for f/i but i would still be nervous without any sort of
intercooling.
if its space constraints, you can run a small water to air setup.. costs will
be around 200 if you can weld aluminum (for the casing) youself.. with a 2
gallon setup, a small 6x8x2" core should be sufficient since as you say, your
particular s/c isnt heating up the air too much (any idea exactl;y how much? i
know turbo's can add 70-100 degrees to the intake charge depending on boost,
but a properly intercooled air-to-air setup will return that back to within 10*
of ambient. a w/a is good for low boost since its more consistent, less
dependant on vehicle motion... but wont cool it off AS much as a large a/a.
*(unless you run a water/aclch mixture, and pre-cool it, with an ice chamber,
etc)

Re: More New Scrambler Details
Hi Steve,
I don't know anyone that runs an intercooler with a pump. It's not
like Doug's pre heating the intake air through a two thousand degree
exhaust.

Cosworth, Subaru Imprezza turbo are both 8:1)
