My dyno results...
 

Okay, i'm still at the dyno right now, i will post up my graph later.

Tuner - Shawn Church @ church automotive in Los Angelas Ca.
Mspnp

at 14 psi on 91 pump gas..I made 275.9 hp / 241 trq. on the dynapack
20psi on 110 octane. - made 302.3 hp / 291 trq.

wanna thank diy autotune / flyin miata / bell engineering / Andrew Kidd aka Savington-COPS.

can't wait to drive home..8 hrs away..

jeez nice numbers! should be a blast.

its very very scary....no traction at all....

Is the torsen holding? Lol... at that point I'd be worried about the diff...

nice numbers

now go own everything you pass

no more racing from the dig. LOL!

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??

Not bad

ger u ass you are to fast.

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.

"manifold wall" ??

Design limitations of stock manifold...

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

which turbo?

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.

awesome numbers.....DAMN IT NOW I WANT TO MEET UP WITH YOU AND YOUR LOCAL MIATA BUDDIES EVEN MORE:D

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.

how does a dynapack compare to a dynodynamics?
