Ambient temperature today was 85-90 degrees. IATs were in the 110-120 range, so basically it's ******* hot. Uncorrected numbers were 268/243. This is all at around 14psi. Boost is ******* solid - EWGs are badass.
BTW - I'm about to turn 21. I've owned the car 3 years.
Starting at 2700rpm on the dyno, it makes 14psi at around 4500rpm. I will get the car on the street at some point to do a proper pull starting at 2000rpm, but it should make full boost under 4000rpm.
WAT, sav is younger than me? Here I am thinking the legendary savington is a 30-something guy with more money than sense, and the miata is his weekend toy. But no, I am mistaken hes just a kid my age. ;~;
Still a badass build though.

I stopped there on boost because the clutch in the car is an ACT HD 6-puck, and it's in pretty bad shape. I want to get a new clutch into the car (possibly an FM stage 2, but a 949Racing twin-disc eventually) before I turn the boost up.

I'm a little let-down by that spoolage. Hopefully my lil tuber will fair better.
So now that your log looks just like mine with the cast manifold and exhaust restriction....any regrets?

Sav and I have basically the exact same dyno with different hot parts and his turbo was bigger...compared to my log manifold. I think we've maxed the intake plenum.
Who's going to make a cheap one?

OK I really thought everyone knew Andrew was only 20 and I was just giving him ****. Hell I'm only 25. New intake huh. Wonder if I can make THAT out of fiberglass.........

You tuned it pretty well? I just keep wondering if you couldn't do more with timing, etc...
Either way, it doesn't look like a boring ride. :-) Congrats.

Yeah, I'm a little shocked by the lack of top-end. The wastegate is amazing.... I'm SO sold on that. I could run 16 psi all day on my mostly-stock parts bin motor, if I could keep from spiking to 20 and hitting boost cut.

It's tuned conservatively in fuel, aggressively in spark (but I'm running straight 100 octane plus water). It dips into the mid-high 10s at the top, but I don't like it to be much leaner than about 11.3 over 7000rpm (and I ran out of dyno time).
Get MSM cams. My stock MSM head is close to as good as my stock 99 head with lots and lots of work into it. :-) But yeah, sounds like mani since your intake track looks pretty straight.






PLEASE!!
