[Shotimes] Gas

[Ronnie Smith]

Not to go off thread with the vehicles, but my 83 V65 Honda Magna performed
much better after switching to the lower octane. It took 2 tanks to test it,
but I was sold and my wallet was a bit fatter as well.  My mileage went up
and the seat-of-the-pants dyno seemed much better as well.  On the other
hand, my father has a 2002 Harley Ultra classic( fuel injected ) and it will
run only on 93.  Anything less and the bike wont run for nothing.  Even the
manual says to use the higher stuff.  I know these are not SHO's.  If the
vehicle is built to run on the higher stuff, run it.  What does your owners
manual say? If everything is working right, you should be able to go by the
owners manual as far as what fuel to use unless you have modified your
vehicle and then this will change of course.

Just another opinion.  We all will have one!

A lot depends on the weather (I believe it was pretty damn cold when
Porter was setting records).  He was also driving a Gen3.  I'm not sure
how those handle the different grades of gas.

Not sure about dyno numbers.  Are you saying someone has done back to
back dyno runs with 87 vs 93 and saw no difference?

Just last week I saw a show on Speed (I think it was Sports Car
Revolution) where they dynoed a newer 911 with both grades of gas.  It
made several more HP with the better gas (can't remember the exact
amount, 3-5 I believe).

The bottom line (IMO) is if you can hear it ping, you need better gas.
Again, this depends on what you're doing.  Daily back and forth to work,
sure, I guess don't spend the money.  But track days, dynos, drags, I
believe you'll do better with the better gas, regardless of what Mr.
Porter's about to say.  :)

I understand what you are saying but how would that explain Ron P being
the fastest at the drags running 87 and other doing dyno runs with 87?

While it might pull timing for when you punch it, I would assume it
would let the timing back in later.

This is where I tend to disagree with you guys.  Timing is being pulled
out and you're not getting all the power that you could.

When it's hot out, if I stab the throttle on either of my remaining
SHO's (91 and 99), I get a quick ping out of it. But it's nothing even
remotely severe enough to warrant running over 87 octane.
