LOL,..I was referring to the transition when you open the throttle, but part throttle, steady-state operations are easily
measured and quantified. Combustion behavior is affected by many things such as, mixture strength. ignition timing, cylinder head temps, air temps, spark plug heat range, plug position, chamber design, valve angles, port design, to name a few.

There are many thing we observe in the dyno room that cannot be witnessed with the engine in the car, but faulty/old ignition components can be seen in your garage at night by fogging the distributor caps and wires with a spray bottle containing water.

It can be quite a show,....

Here is the kind of thing we see on the dyno:

this is where a G-Force meter would come in handy. I bet Pep Boys or the like have a zero to sixty / quarter mile timer that would work to prove my mutt dyno story.

on a different note(I think) I busted my driver side rear sway bar mount. the passenger side had been fixed at some point and today that clunk sound as I hit the 1" lip on the driveway and I knew what happened. I'll find the camera for a second oppinion..

Amber Gramps

here is a real problem. one worthy of all this time and tallent you guys pound into your keyboards. fix this one, will you.


David, "bla bla something something remove your cranium from it's rectal storage unit something something bla bla bla" um, are you saying I have my head up my ****? LOL, now that was funny and I finally get it. I don't know how I missed that yesterday. THAT is what we need around here.

O.K. back you work. tell me how to fix this the right way this time.

DARISC

That neck snapping 100 octane stuff will cause just this sort of damage on occasion

Amber Gramps

Man you guys take me to school sometimes

Amber Gramps

O.K. here is living proof of just how powerful the 100 octane is. funny thing is I didn't use it today. (had wife in car when filling up. she doesn't need to know)

maybe this wouldn't have happened if I had sprung for the good stuff!

Steve Weiner-Rennsport Systems

Cut those OEM mounts off and weld a pair of WEVO ones on.

Voila',..no more troubles.

Amber Gramps

do you stock them and are you making lots of noise in the shop tonight?

Steve Weiner-Rennsport Systems

Indeed I do and thankfully, I'm done for the day (night).

How 'bout mechanical engineer? I'll verify. This confusion has been around for a long time. What the octane does is allow more usable cylinder pressure without the accompanying damaging detonation. The extra pressure could come from higher compression ratio, advanced timing, a more efficient induction system, or a few others. All these things build horsepower, octane simply permits it.

Amber Gramps

Now that was funny.

I've been thinking about this all day and have decided after using gas in motorcycles some thirty plus years, and after 24 years of driving and 20 years of driving as part of my job, and having say 100 years of automotive racing history to refer to, and having half the human race behind me, that what's his name is right, octane only allows power adding components to work as designed. Kind of like a big Employment Development Department for the motor. Fuel comes in and says "I have the octane so you can work to make more power now." come on it's funny "hey you over there, induction system, I'm at 95 today so you have permission to work harder today" oh and this is a common one around the track..."hey, quiet, stop your pinging or I'll make you blow yourself up."

it's kinda like saying that two match sticks are exactly the same and will both burn just as hot as each other when one has the blue tip and the other one doesn't. well of course they are exactly the same...

it's like saying the quantity of gun powder doesn't matter as long as it has some the bullet will be permitted to go fast, just as fast as if it had, say, an RPG on its back side.....

Douglas, all physics and chemistry aside, let's not underestimate the power of the brain to interpret and create illusion which gets transformed into reality: if you think you are faster, then you ARE faster, and that is worth the price of 100 octane!

DARISC

That's a good point, except illusion becomes only "apparent" reality, which admitedly can certainly be fun.

However, Doug, having reached the conclusion that you have, take heart and consider that for the price of not a whole lot of tank fulls of that super expensive race gas, you can mod your motor to even exceed your current illusion - then it's done, paid for and the real, non-illusory power will always be there with every tank of 91 octane gas (and the kids college funds can grow quicker ).

Amber Gramps

Murphy, I have taken down the picture of you, the car, and your bride in favor of this guy. Now, let me go back to my happy place.

darisc, gas is tax deductable. the turbo kit is not.

Amber Gramps

so, are we at the dead horse stage yet?

Murphy, I already put your picture back up as the wallpaper on my computer. customers can see my computer from the will call window and were wanting the "hot picture" back up. (so was I)........Tokyo?
