Sorry, still confused. Are you sure you are not mixing up the OEM 8 turbo and the 35R?

sorry if the colors of the plots aren't that great. matlab does a terrible job of making jpg from figures.

35r with log manifold = full boost at 4800 rpm. stock = 3500.

Ok, I thought I was losing my mind there for a second.

1. Although the OEM IX turbo may have hit maximum PSI (full spool) sooner than the 35R, the 35R still spooled quicker as evidence by the dyno graph. The 35R was making ~21psi @ 3350 whereas the OEM IX turbo was making ~21psi @ 3400.
2. The 35R only gained ~2psi between 3350 and 4800, and in my books that is pretty darn close to be fully spooled.

I think you're confused about the 35 graph. It's not making 21 psi until what looks like about 4800 rpm. I NOT SURE you'd ever get a 35R to hit 21 psi in 3rd gear on a 2.0 4G63.

the 35r has like 1 psi at 3500 rpm...

Oh snap! Forget all that I have said about it spooling quicker.

Nice Graph!! make this a sticky

people just need to remember that this graph is to give an idea on boost vs. rpm for various turbos for the evo.

this is not sacred & everyone else will expereince different results.....it's just a basic comparison.

I wonder if we were to try to extrapolate to higher boost levels... how much RPM you think it takes a 35R to make 6 psi more?

BTW nice comparison to the OP.
