the compressor wheels are the same, so you should expect similar power. I bet if it were the same motor and spark map, the 2860 would simply make more power up top, but you'd see that sacrifice of low-end, which isn't a big deal.

That's what gets me - something with that much of a turn off on the top end should have a lot of bottom. I wonder what boost as a function of RPM was... Maybe they were in a really low gear on the pull compared to paul.
To me it seems like they should have top-end, but then again, the engine management isn't ideal, is it? Restrictive intake?
Got me. I just need to tune my car. Sometimes it runs well. :-P

it's just a turbo for a different job.
Again look at this comparo. this was the same car and same boost: http://www.flyinmiata.com/tech/dyno_...emy_potato.pdf
while it lost 500rpm of spool, it gained 10hp/10tq. probably runs a little cooler as well, so better for track days where you dont need that extra low-end and can use all teh heat management you can get.
