What are EGT's doing?
That's interesting. I went with the larger turbine for EGT lowness. However, I still need to get back to the dyno because my AFR's are too rich out of boost, and spark table needs some work. I plan on doing this in May. There is still more work I can do to make my tune better, and I'm not sold on using a smaller turbine housing to lower spool exclusively. I think I can still reap the benefits of the larger hot-side if I work on a few other things.

considering that's a dynojet, he's making similar #'s on a 9.5:1 motor with a pea-shooter 2554. lol
My car would make 292whp/282wtq on that dyno considering the 12% change from a local dynojet to the dynodynamics which I've shown in real data, and backed-up by keyboard jockeys.
However, my interest is piqued because my car makes more power than I wanted initially. I'm probably just going to leave it how it is.
Any chance we can get a look at this car's spark table?

Well I would say I am glad I got the .64 AR housing on my 2871. I'll give up a little torque for that much additional spool.
Did I mention even with my initial crap tune I was seeing 12 psi at ~3300 rpm?

I agree that the area to the left is educational and interesting, though I wonder what difference enriching it a bit would make on the red graph.
For a street DD (or autocross even), it looks like a .64 would be better putting around town. I think the low end benefits are better than the minor HP drop comparatively.

the graphs quantified it. now you're limiting the scope of applicability by saying it's an MR2 and not general for all cars. a quality of that dyno test is that it was done on a specific car. qualify.

I have to ask... What does this MR2 bullshit have to do with the price of rice in China?
I'm going to agree with Hustler here. For open track, the tater is the better choice.
