Good god that looks like fun!

Any under hood shots?

That's beautiful.
Just what I'll be aiming for.

Is this on pump or e85?

and yes please post underhood

lol you mean fun as all hell.:skid:

No build thread and no reroute i also don't run a thermostat.

I hate your guts. Not really, it's mostly jealousy cause I wish my 99 put those numbers down. I'm only 100hp less than you! Good pull!

I forgot to add it would have seen 350 but for some reason the wastegate just didn't want to hold boost. So once I get my new wastegate and fix a few small thing ill be going for my 25psi tune. =]

Looks like you're getting the hang of the DIYPNP. Great numbers Mike!!

When you get a sec, please email me a copy of your .msq. I'd like to have a look at it.

I have yet to see this car in person (did you come to the show..if so i was too damn busy to notice).

I love the RPM scaling ... lol.

no i have not been to any shows but i have been trying to get every one in ct to finaly meat up still. lol

here is a list of what i have sorry if i left anything out

Head stock

bottom end
belfab H beam rods
super tech pistons 9.5:1 comp
HV oil pump
full ARP studs

Turbo setup
ebay manifold with a 16g flange
New style EVOIII 16G
full 3INCH exhaust
VTA wastegate

Other stuff
custom intake manifold
DIYPNP with 4 bar mapdaddy
stock fuel rail made into a dual feed fuel rail
680CC injectors
coil over plug
mazdaspeed six speed tranny
mazdaspeed diff
walbro 255lph

All these new dyno plots showing up on this site really have me thinking more and more about turbo efficiency.

From what I understand the 16g is considered a relatively small turbo, right? These are numbers that we usually see from bigger turbo's such as a 2871, 3071 or a larger t3. I know there are always variable's to take into account(intake manifold, tubular exhaust, etc.) but, is this turbo really that efficient?

I must be missing something here, please fill me in.

Miatamike203, I am envious. Those are great numbers. I bet the car pulls like a freight train. I can't even imagine what you're going to put down at 25psi:drool:

Also i would have seen 350whp on 18psi but my wastegate was not holding boost to well in the upper rpm range it started to fall off around 6500 that's why it started to drop in whp.

The car feels like nothing i have ever driven and i have driven a lot of cars from your everyday civic to some of the nicest and fastest super cars thanks to the 2 places i work and worked at. No traction problems ether this i was surprised about, once you hit boost good luck trying to move in your seat and good luck trying to pass me. lol

Tell us more about this > ebay manifold with a 16g flange < .. how does it hold up? i know a friend that had bought an ebay 1.6 kit and it fell apart in 3 weeks.. not saying yours will just wondering which one you got and how much you paid? was it the ebay kit we all see got like 1000$?

I am aiming for this exact powerband with my current setup

very nice man. congrats

Its so nice to see the miata community finally start stepping up to larger turbo's.

A year from now i'll bet half this forum will be roking taters and larger
