Re: Turbo on a Jeep
Yup, pretty much anything may blow the doors off a turbo charger
from a dead stop, by the time they spool up it's time to change gears
and another two second delay, during which your Father's Oldsmobile has
won the race and is shutting off.

Ahhh, this is why you install a B&M hopped up automatic transmission
and launch the thing by standing on the brakes, floor the gas, then
release the brakes. Except of course on really big turbo motors
which either ignore the brake pedal or rip all the rubber off your
tires, or both.
Porsche never really had that much trouble with turbos, other
than scaring the heck out of new drivers on the older ones
when they released the high pressure on the outlet side
with a simple popoff valve...about like a pistol going off
in your ear.

Re: Turbo on a Jeep
Hi Lon,
And I ran one of the original (Real) B&Ms a '56 Cadillac four speed
hydro with a four to one low behind my Y Ford race engines:
http://www.----------.com/B&Msticker.jpg
I thought the pop-off valve was just to limit the power of the Indy
type racer, like a restricter plate on a stock car's manifold.

The turbo wastegate limits max boost via signals from the ECU.
The pop-off valve or blow-off valve doesn't limit power, but protects
the impeller/ turbine assembly and intake system from harmfully
excessive pressure and stress. When the throttle plate slams closed,
the turbo is still spinning a gazillion rpm and providing boost. The
pop-off valve dumps all the high pressure air into the atmosphere,
resulting in that loud Pro-Rally noise. A bypass valve is much more
civilized and dumps the air via a hose back into the inlet to the
compressor.
I agree that turbos aren't usually suitable for off road use. Some
are, like this non-Jeep application, which is unfortunately out of
production:
http://www.airpowersystems.com.au/sa...int_turbo.html
For kicks, read the two magasine articles at the bottom. From what I
have heard, this system was mainly sold to Middle Eastern sheiks
looking for ultra-high top speeds from their Land Cruisers. There
aren't very many in Oz or the USA.
I have had a couple of high performance turbo cars and just loved
them.
