Pick up a Hemmings Motor News at your local B. Dalton Bookseller or

Vermont and subscribe.

Hemmings is the car collector Bible.  You will find sources there for
virtually everything you need to restore your Firebird.

Off Road Roll Centers

        I was just wondering if anyone in this group knows the general
height of the roll centers, and possibly the roll axis inclination for an
off road racer.  I have read "Tune To Win", but that boo focuses primarily
on road racers.  Any info is appreciated.

Re: Steve and Others

Oops.  Uh, guilty.  I guess Steve brings out the worst in me.  BTW, if
you guys want to see some REALLY screwed up ranting and raving, look in
on the "discussions" over in r.a.driving.  Subjects include – Honda v.
VW, NSX v. BMW, NSX v. VW, NSX v. everything under the sun, whatever v.
whatever, stick cars v. auto cars, and Car and Driver becoming a
non-enthusiast mag.  The latter even has Martin Padgett (con. editor for
C&D) in on the fray.  The x v. y discussions are headed by some guys
named Lloyd, Ryan, Bryan, and some others.  They each post upwards of 10
messages a day to argue about who has the coolest car.  They use some of
the most skewed logic and data around to back up silly claims. Sound
familiar?

V-8 swap in 1800E

        OK, I’ve decided to go ahead with the V-8 swap in a Volvo 1800E.
Many of you will think I’m crazy, and perhaps I am. :)  But… I have gotten
a lot of possitive feedback and recomendations, so what the hell.  It’ll be
fun.

        Anyways, I’ve also decided to keep any interested readers of this
newsgroup up-to-date on my progress.  Also, I might be asking again for advice
and help on locating strange parts.

        I have located a solid body to do the conversion on, and I think I have
found the drivetrain, which consists of a 1992 Mustang H.O. 5.0L with 23,000
miles on it hooked to a 5 speed tranny.

        Until later…

detonation signs

Subject: Detonation signs
Newsgroups: rec.autos.sport.tech
Organization: North Dakota Higher Education Computing Network
Summary:
Keywords:

I have heard a lot about the damaging effects of detonation.  Compression
ratios and advance curves seem to be the biggest factors along with
gasoline octane ratings.  Pinging or knocking are the signs most people
talk about when they refer to the presence of detonation.  Are there any
other signs?  Can detonation occur without pinging being noticable?  I
want to be sure it isn’t happening in my engines.  So far I haven’t heard
any ping or knock.  I am using a aftermarket advance curve kit in an ’83
305.  It has been bored .030, uses stock cast pistons, has a crower
.456/.466 lift cam, Z/28 valve springs, headers, a contender intake and
650 double pumper.  I have been using "regular octane" gas, but plan to
use ethonol most of the time.  The exhaust is rather loud, so I can’t
hear every sound from the engine.  Am I too paranoid about detonation?  
Any reasons why I shouldn’t or should worry about?  Please help me lay my
problem to rest.

RE:
        There are several differences,
1) Lead content- Yes, there is still lead in Some AV Fuel. This is THE
LEAST of the concideration.

2) Volitility- Av fuels have a lower ‘vapor pressure’, that is, they
tend to evaporate at a lower rate. This reduces vapor lock at the
lower atmospheric pressures at altitude. Also can cause vaporization
problems in engines not designed for this fuel.

3) ADDITIVES- Av Gas contains acids and other additives to keep the
aircraft engine clean. These additives tear the shit out of engines
not designed to run/handle them. Aircraft engines have a quality of
parts and construction techniques/ surface treatments that enable them
to resist these chemicals.

4) Thermal energy- Av fuels have more heat and possibly burn at a
higher temp than pump gas. While the automotive COOLING system may be
able to dissapate the heat, those things between the fire and radiator
may fail, ie: piston domes and valves come to mind.

Overall, for at least these reasons, av gas should not be used in an
application not specifically designed for it.

A tire is a closed system. Put the cap on your toothpaste tube, squeeze it
hard and then stick a knife into it and watch the fun. Actually, if the
tube has been flattened and you pinch the narrow sides in the right way
the tube starts to return to its original shape, increasing the internal
volume and lowering the presure, thus sucking the paste back into the
tube.

Garret Turbos

Hi,

I have been offered and now seriously considering purchasing a turbo
for my Integra.  I think it is a Garret T34 hybrid turbo with all the
works.  But before shelling out 2 grand, I would like to know a little
more about it.  So my question is, does anyone know much about Garret
turbos in general?  Their naming scheme, general characteristics of
some other models?  I want to know about how this turbo is compared to
some of the other Garret turbos.  I don’t suppose there is any FAQ, or
address anywhere to receive this kind of information?
Thanks for any help.

Nitrous Oxide…

Does anyone out there know what knowledge would be required for installing a
nitrous oxide system in a car? (Say…a ’93 civic with the 102hp engine)  

and how much more power would it give a car of this category?  

And maybe a hint as to what kind of price it would cost to get one.  

And how would using it in the cold weather (sometimes -35 C) effect my
safety by having a nitrous system?
