Seriously impressive pump gas numbers. I bet you didn't utilize 10-12 octane points of that 110, though.

Realistically though, what's a guy got to put in his miata to have a sturdy reliably 275 rwhp handling diff??

Sleeper- I think you've hit the manifold wall on high boost given the disparity between tq/hp vs. 14psi. It would be interesting to see your dyno curves.

I missed what turbo you're running. I'm going to assume GT2560 though.
Great numbers, I want dyno time.

Design limitations of stock manifold...

Edit: Just like "max boost" is a very technical term, so is "max flow."

At 20Psi you should really be making more power than that. Somewhere closer to 360-375hp, but there may be some restrictions holding you back.
Do you still have the stock exhaust?
How conservative is your timing up high?
A/F too rich?
What injectors are you running? 550's run out of steam around 300hp

I agree someone needs a BEGi manifold.

I too am surprised you weren't seeing Z06 smoking numbers on the second run.

As a former differential destroying champion, I feel like 2 things are going to destroy a differential:
A. Launching, especially with wheelhop
B. An aggressive clutch

Coming from the S2000 community (Honda sourced the S2000's differential from Mazda, as I understand it the S2k diff is basically a beefed up Miata diff), some people are running 500whp without any problems, others have blown diffs at stock 200whp. It all depends on how you treat it, just b/c you're making 275whp doesn't mean it's going to explode.
