one boring dyno video:

Before someone comments it. Those are newton meters and kilowatts
So it’s: 284whp @6400rpm
peak torque: 265lbs around 4300rpm
boost was only 14.5PSI
there was something wrong with the wastegate signal hose and I didn’t get more boost.
Wastegate was fully closed (in Adaptronic EBC wastegate settings) but still it didn’t boost more. edit: turns out my wastegate lid was leaking

But car runs fine. There’s odd small oil leak in oil pan and I don’t feel like re-sealing the whole oilpan. Maybe I just leave it.
And then there’s a usual E85 catch-can issue. I get about liter of water in one trackday. But there’s a little I can do to that except build super big catch-can

edit: Yeah it says on the dyno that the mode is "Shoot_4F". That's for 4 cylinder 2WD Forced induction flywheel "estimation"

BTW your air filter heat shield looks frikken fantastic. But it won't work. The heat shield itself will heat up. And radiate the heat to the air filter side.
Cold air intake is only worth it unless it is actually sitting outside of the engine bay like cowl induction. Hornetball does that and recorded good results

And IAT isn’t problem. My cheap (95$) china IC is doing good job there. Air temp before IC = +125°C. After IC = +28°C (max)

It came with two springs. One is so stiff that it makes loud surge noise every time you let off the gas. And the soft springs other hand is so soft that it leaks on idle. But I read somewhere that it’s normal to BOV leak little on idle. (that almost rhymes)

Can someone remind me why are we still using superchargers? ![Bang](https://www.miataturbo.net/images/smilies/bang.gif)

This is my current GT2560 setup vs. previous FastForwardSupercharger™ MP62 kit in the backround. If you're looking just boost level, at 2200rpm turbo start making more. Still I'm sure GT2560 is making a lot more torque above 1800rpm although boost pressure is a bit lower. It pulls like big turbodiesel engine. I hit my boost target at 2900rpm! and this is with BP4W head not the VVT one. f*cking awesome
GT2560 fifth gear pull: (rpm | psi)
1879 2.75
2022 3.48
2122 4.20
2276 5.24
2390 6.82
2456 6.96
2564 7.98
2662 9.72
2776 11.46 (wastegate opens)
2866 12.64
2996 15.38 (boost limit)
...$4695 for FFS supercharger kit? No thanks![Giggle](https://www.miataturbo.net/images/smilies/gay.gif)
ps. You guys should see the IAT temp log between turbo and FFS sc
no wonder that I was able to break 2 engines with the supercharger
