gutted cats and black holes!! ftw!

 

That's nothing. I've got hook ups at Cape Canaveral and I got a few gallons of the rocket propellant into my Camaro. That thing flew!

 

Due to the massive and unexpected increase in power,a gutted cat and 100+ octane fuel should not be used at the same time, unless you are a properly trained and licensed individual. Consider yourself warned! LOL

Octane rating of a fuel is a measure of its antiknock property, and has nothing to do with the quality of the fuel. Isooctane is the the standard on which antiknock property is measured. A fuel consisting of 100% isooctane, a liquid hydrocarbon,is arbitrarily assigned a knock (octane rating) of 100. In the good old days isooctane and heptane were the main components of gasoline, and as an example, a mixture of 85% isooctane and 15% heptane would belabeled as 85 octane. Later on, lead (tetra-ethyl lead)was added to gasoline and fuel with better antiknock quality than100% isooctane became available, andcould be rated over 100 octane, depending on the amount of lead. Todays pump gas is mixture of many different chemicals and may not even include isooctane, and the lead is gone. The quality of gasoline is determined by the additives and care used in the refinery and distribution, and nothing to do with octane rating. An interesting fact is that lower octane gasoline usually has a somewhat greater energy content than higher octane fuel, and if the engine burning it does not require the higher octane, it will make slightly more power withe lower octane stuff. You guys with the stock V6 engines can test that at a drag strip by running regular or mid grade, and then changing to the 110 octane stuff sold at the strip.

As for spark timing. Some people are under the impression that the greater the spark advance the more power the engine will make, so they run 100+ octane fuel and advance timing to where the engine justs starts to pings. At this point the engine isfiring way too early in the compression stroke and actuallytries tospin the engine backwards causing serious loss of power. There is a limit to how much spark advance can be used, regardless of the octane rating.

As for jet fuel, JET-A, JET-A1, JET-B, JP4, etc.. This stuff is similar to kerosene and diesel fuel, and unless you have a car with a diesel engine it won't work. Don't put JP4 in your deisel, the stuff is for fighter planes with afterburners and is a 50-50 mix of kerosene and gasoline. LOL

 

Yea I already said that Pete, this D-bag is not going to listen to anyone.

 

I don't think there is tooo much diffrence between the two because in my country we used 95 octane since ever
then before a few monthes thay started using 91 octane there WAS NOT too much differencein the the car preformance
only a very small one it was like 2\10th of a seconde in drag and only people with cars like mine (5.7 LT1 impala)
could notice

so it's not all BS but it's not magic gas ethir [sm=laughat.gif]

 

ur talking about a drop in octane. its possible that a car that wont detonate on 91 will detonate on 87, or whatever the interval might be. if it knocks, the computer pulls timing. = slower. so the higher octane is in no way, shape, and/or form producing more power. it is only resisting detonation allowing your car to make the power it should be anyways. to the OP, who is now lost somewhere deep in bannination, but maybe will come back to look as a lurker, prehaps your car has had its timing advanced and you were knocking on regular gas. the higher octane fuel only brought u up to your full potential, but did not create any more power. however, i find it amusing that you feel the av gas made your stock 3.8 take off like a rocket.

 

That's what I was thinking. What if the car was simply finally running normal?

 

which means his F'in rocket is just like every other stock 3.8
