Yup, that's the number I remember too-- 0.1 sec/100 lbs.  I remember
in the 70's, I had just lost a drag by .04 sec and some famous racer
came by and said, "Your lady is 50 lbs lighter...  If she had been
driving, you would have won that one!"  Then again, he could have
been referring to my barely-passable racing skills...  :-)

No, just press the connectors on the upper side (i.e. towards the radio) and
pull them out.

No, your car uses M2-a and is correct.

As described in M2-a. There is no problem, just straight forward.

Put a toggle switch in between if you want both functions.

Connected, hose and inled capped off.

No and try to have not too long hoses.

No, use the fuel pressure line that comes out of the plenum.

Close to the source.

Left or right rubber gromet in the firewall.

Not that I have too much time on my hands tonight, but I was curious, so
I took Barry's formula and re-arranged it as follows:

            t=5.825*(weight/285)^1/3, where t is 1/4 mile time, and ^1/3
means take the cubic root. Here's what I got using an HP of 285 and
varying the weight from 3800 down to 3400 lbs:

t=13.8, weight @3800lbs
t=13.69, weight @3700lbs
t=13.57, weight @3600lbs
t=13.44, weight @3500lbs
t=13.31, weight @3400lbs

Barry, where did you get these formulas from?

Thanks,
Bill Wagner

I snagged them from the web somewhere at some point in time.  I have seen
them in several places.  They are clearly estimates, and crude ones at that,
but they apepar to be "in the ballpark".

It is interesting to note that the .5 sec per 500 lbs generality posted
previously more or less agrees with your formula.

I'm looking for an EGT meter, I want feedback regarding brand, quality and

What's best, digital or analog?

Also, is the best location in the rear exhaust manifold? What temperature

Hey what's up..  I'd look into the A'pexi EL series or the new (just released
so not that many have them) HKS gauges.  Both the EL and the HKS EGT's have
peak hold AND 30-second playback.  The 30-second playback feature has been
very usefull when tuning, especially with the 30-second playback boost
gauges..

HKS has slightly better quality than A'pexi, but then again the A'pexi gauges
are around $50 cheaper..  The main problem with the A'pexi gauge is that the
probe is fairly long, whereas the HKS probe is half as long.

I'd recommend installing the EGT in the front manifold where the three merge.
Look for 850-925max temps at 17-19psi.

Hope this helps,
Mike

Subject: Team3S: What year styling change on 17" rims?

Is there any change in the stock 17" rim styling between '94 and '97 VR4? I'm
looking at buying two sets of used chrome wheels, one is a '94 and one is a
'97. I'm thinking about buying both sets and using the best wheels from each.

Thanks,
Paul Klusman

Both the styling and the sizes are different.  The '94 is a
simple spoke design, flat on the outer edge and is a 17" wheel.
The '97 is "dimpled" on the flat edge of the spokes to give it
a little more "technical" look and is an 18" wheel.

Actually, the 95-99 vr4 rims are 6 spoke 18" rims.  The SL came in a 17"
chrome rim from 97-99.  Check out my wheel page at
http://www.mn3s.org/wheels.html before buying any rims so you can verify
what your getting.
