Was wondering what sort of timing advance you run at WOT between 6 & 7 KRPM and with what octane gas?

WJM

depends on the turbo and the IATS

PanTTher

You mean BMEP & intake air temp. This wasn't a rhetorical question. and you're no help.

Grim Reaper

and being a intraweb cvck isn't going to help your cause either....

PanTTher

it's not helping you either. If you can't be helpful take a hike.

WJM

and i could tell you what k03 guys run, and i could tell you what k04 guys run....but some chips dump a ton of fuel in up top to run the timing they do, partially due to the Intake Air Temps...

so either ask an intelligent question with all the necessary parameters... or take a hike to TThe TT Forum TTo GeTT TThe uninTTelligenTT answer you are looking for.

PanTTher

and you got one back in return.

Maybe I was too blunt for you and your friend but I rather you didn't tell me anything than blurt out some crap or hearsay crap that you don't seem to quite understand or heard from a friend of a friend of a friend.

The type of turbo one runs has nothing to do with timing where as cylinder pressure and intake temperature does. Your k03 or 04 or T series or GT series deliver the same 22 psi of pressure but varying flow rates based on compressor size so it's not entirely implausible that one can run the same timing on all these turbos as long as one can control the intake temperature.

A good and proper answer would have been: Hey look on the A4 forum or blah-blah-blah forum for some answers and or see such and such person's posts for some data.

Now this sudden case of stuTTering that you've picked up is completely juvenile.

Do you really want to get into a discussion on how turbo compressor efficiency relates to thermal eff., and how dumping extra fuel will reduce the chamber temperature? Not to mention the inlet and exhaust piping associated with different turbo kits impacts the amout of airmass you can put into the chamber for a set pressure and measured IAT.

Fact is pressure doesn't mean anything... in the thermodynamic world all pressure is a potential of velocity. The amount of air mass that you can flow through a system the more power you are going to get. Now again you of course realize that pressure is partially dependent on temperature.

Now we can go into combustion dynamics including flame speed and how that relates to air density, air/fuel ratio, chamber temperature, and how that will determine how much timing you can run without having to worry about detonation.

But you're right i dont understand....but it sure sounds like it depends on the turbo software and IATS. Since none of your posts have stated what turbo or intercooler or software you are running, what assumptions are we supposed to go on? So what turbo, chip, etc are you trying to figure out how much timing you can run on?

WJM

let me put it another way... in order to limit your variables...ask this question in the TT forum

PanTTher

I have a decent analytical background. And please don;t be shy.
