i have office 2007 at home which makes the chart look pretty and sharp. looks like *** off the older verison.
anyways, clearly see 5 groupings: The super spoolers. The 2554 and 2560s. The T3s. The large trims. And the super large trims.
interesting to see how my boost build compared to chad with same turbo manifold and exhaust. looks like my headwork may help me below 3K, despite my 200cc less. granted I'm still making 200cc less power :(
I plotted Cueball's data cause I am at home sick today and freaking bored. I cannot repost the new graph since I am using Open Office and a lot of the Excel formatting is lost in translation.
But, Cueball's spool is right in there with the 2560 plots. Very nice! The only thing I can see in his setup to explain this is the S4 manifold. If that is the case, then it seems like a 2860 with an S4 could be a good choice for the street since it still spools nicely and should be a bit more efficient than the 2560.
Thanks guys! That plot was on my freeway commute this morning. Got out ahead of traffic, dropped to 1500rpms in 5th and floored it. Overboosted to 13psi until the EBC kicked in and dropped back. Let off then. 2.5" enthuza with race cat. Corky talked me out of the 2560 in favor of the 2860 on my system. Now I know why.
All those super-charger guys talking about instant spool and flat torque can kiss my lily white behind.

What's a race cat? A resonator that looks like a cat?
Or a feline with racing stripes? (LOL I shaved one of my long-haired cats once because I was tired of his shedding, and started with racing stripes)
If you did that, Tim would just remove one of his turbos and spank everybody. And yes, I think it was mentioned to make pulls/data 1:1. So cueball, you need to do a fourth gear run for relative placement in the data.
I based the psi numbers by subtracting an assumed 1 atmosphere of 12.46 from my map values. This isn't entirely accurate because the altitude of my city changes so much depending on what part of town you are in and I didn't want to break out the GPS. I estimated on the low side of 4500ft.
