100 octane in a DII?

No, EGT actually decreases with detonation. Detonation disrupts the boundary layer of gas which insulates the piston and cylinder head from the hottest gasses, which exposes the engine to the higher temperature combustion gases. Therefore, more heat leaves the gases and goes into the piston, etc. EGT drops, power drops, engine temp goes up.

But you knew that right, Mookher?

Come on, try the easy one, why is it an incorrect internet legend that they have higher octane fuels in Europe? "Play along" ;)

Which is why pistons burn holes in them and skirts collapse and upper compression rings break.

Expressed using a different formula. Same gas, same characteristics, different test method to calculate burning characteristics.

Mookher, you started out making enemies and have somehow redeemed yourself several times. I doubt Jupiter has the same ability.

these flaming jackasses are gonna come onto the forum and try and 'teach me' what EGT and detonation is? are you fucking shittin me or twat?

yeh,
hokay...

Exactly. In Europe they only test octane with the Motor Octane Number test. In the US, the pump label Anti Knock Index is actually an average of the MON and Research Octane Number. With a given fuel, the MON is always higher than the RON numbers. A given fuel might have a 95 MON (printed on the pump in Yurp) and an 87 RON. That works out to a 91 AKI which is what they'd print on the pump in the US, for the same damn fuel.

MON is a much more useful number for us, because it tests the fuel under conditions much closer to the real world. 900rpm vs. 600rpm, higher inlet temps, etc.

Different fuels of the same AKI number will have different octane sensitivity. That is the difference between the MON and RON numbers. That means that while one 91 AKI fuel might run fine in a high performance engine, another 91 won't, depending on conditions.

But, you knew all that, right Mookher?

Go on hotshot, try the EGR question. Bonus points if you can tell me why the OEM's stopped using EGR in the 90's, then brought it back again in the 00's.

Be a sport. ;)

Stop avoiding the fucking question, nut up, and give an answer!

I never challenged what you said gem. I do not have a clue about race fuels, jet fuels, BMET, EGT, ect. I just think you're a wanna be badass. It is somewhat pathetic. THIS is a forum, quit trying to prove to people your tough shit. No one cares. Sure, you know about race fuels, and Possibly how to wheel. Props to you.

Rovercanus, Are you my little dog, ahem bitch, that follows me wherever I go.

Sit boy, Sit. Beg boy! Good boy. Heres a Treat :fuckoff:

Jupiter,
Better than you have been run off for less.

I suspect you have probably attracted attention those of us who enjoy the board would not want.

Either grow up or go away.

Wow Pete, your dad seemed like a nice man, I'm sure he would be really proud to see how you are turning out. It doesn't sound like you are learning a damn thing in that school he's sending you to.
