1JZ vs 2JZ (Laying the myths to rest.)

[Silent Knight]

A stock 2JZ flows about 238in and 154ex at .400 lift.
A stock 1JZ head flows 215in and 133ex at .400 lift.

Flow test were performed on a SF-600 Flow Bench.

238 and 154 whats? Small african children per week?

[Adamal]

I'm taking a REAL wild stab in the dark here and saying cubic feet per minute? Only because it sounds more probable that small African children per week.

[Malcolm]

many people don't realise that small african children per week is a flow standard recognised by the SAE, and the prefered flow unit used by Formula 1 head engineers

actually this isn't true, I made it up, however it's always good to state units, nothing worse than only getting 98% in a test because you forgot to add the unit on the end of your answer

[KinLoud]

Its all to do with port velocity...
A smaller port means the small african children need to run faster which aids volumetric efficiency.
Flow benches measure using a constant flow, not a series of short pulses as occurs in a working engines intake.

Exactly. When you try to shut the gate to prevent the small african children from getting into the Red Cross food tent, the faster they're running, the more that will be able to squeeze through before the door finally slams shut

[Adamal]

However, when the door does shut, wouldn't this create a large ammount of back pressure, with the buildup of other small african children trying to get to the Red Cross tent?

[RomanV]

The children reflect back in a 'pulse', due to what is known as chitateecholtz resonance.

My gen 2 3sge motor has ports that are about 3/4 of the size of the ones on my gen 4 3sge....

And the gen 4 makes 40 or so horsepower more, in factory trim.
(Quite the opposite situation of the 16 valve 4ages )
Which I found rather surprising!
But its not the only difference I suppose, and it could still be a hinderance more than anything I guess.

[Malcolm]

as Dave said, you get a pressure wave of small african children that reflects away from the food tent, and if you tune the village roads correctly, the wave will reach the refugee camp just as the gates are opening to the medicine tent, allowing a greater number of small african children to get their hepatitis innoculation before that gate closes.

As well as kicked off TS if the polls right...

hehehe

You said "small african children" and "aids" in the same sentence... surely no one found that funny.



And that whole units thing, wasn't it the americans and the poms stuffing something up at Nasa with one using miles and one using kms or something? Who needs details to bullsh*t their way through a story?

feet and metres for the original mars rover...

[Silent Knight]

Sorry...it was measured in CFM.

CHILDREN in a FAMINE per MONTH.

anyone got the conversion factor to small african chilren per week??

[Adamal]

Divide Pi by the number of small African children, where Pi = enough to feed a town of small African children per week.

This equation may sound odd, but its similar to farenheight - celcius conversion, as 2 x Pi would = 2 Children in Famine per Month, however with small African children per week, you would divide the number of children to get X small African children per week per week. It becomes rather exponential.

Holy shit, if im going to hell for just reading this and laughing, you're all so screwed. Nice to see hard facts.
