I want your spool data!
#262
Well then. Your td04 does not spool faster then, does it?
Also, since when does 6.8=10?
Finally, my monster 1.6 spools a t3/04 to 18 at 1800 rpm. Well, it would in 4th, if I hadn't never made it.
850 rpm = 8.6
1800 = 12.2
2800 = 38.645, for the transmission
18psi, see
Damn, I type too slow.

Read, i already said that 10 psi at 2500rpm was in 5th gear, i dont have any 4th gear pulls but i posted a 3th gear pull above
Or wait, these can also be faked

Finally got the engine running in a new car, This time a 1999 NB
Same specs as in my NA except for the 3" exhaust and the new firmware, still can get the boost control settings right. little different with the bias settings.. Sometimes it overshoots and goes into overboost. My target at the moment is 200kpa. Will up that later when its running good Only drove about 2 hour total now

Why has boost response never been measured here. As in steady state cruise at a given rpm/no boost to WOT/XX boost for say 1s. After that I don't care what it does. I'd like to see three standardized rpm points like 3500, 4500, 5500. The lag in boost returning after closing the throttle has been my personal litmus test, not how the boost build from a WOT roll on from low rpm. Why?, because the roll on is irrelevant. Who drives like that? Boost response after closing the throttle is how we actually drive it.
In 2006 when I had an intercooled GT2554R running on an emanage Ultimate with a 2.5" straight pipe, I datalogged it getting to 4-6psi in about 200ms and rising to 10psi in less than 1s at anyhing above about 3000rpm. Unfortunately I no longer have the program that opens those logs. Pretty much replicates. Andrew's posts from 2008

So if I am understanding you correctly Emilio, you are saying that we start out in 'x' gear at 3,500 on flat ground and step on it full throttle and measure the boost built in one second?
What gear do you propose? Maybe this should be a separate thread, or do you think it should be added on as a separate measurement on this one?

I am also curious to see if gear matters substantially at all. As this is a racing concern, what gear would you be in when you hit the throttle and needed instant (or as close to it) response?
If done on a dyno, I bet torque and HP would be nice to see along the same curve.
#278
I agree. 3rd gear steady state cruise on a levelish road starting at 4000 rpm. Immediate WOT. 2-3 second log should be enough to see what we're after. Most turbo's should light pretty quick under these conditions. I second the start a new thread notion.
