VVT + VICS + Boost + MS3X = ??

Yes, these numbers would be on DIYAutotune Dynapack.
Sorry Zabac and JayL, Flipside manifold fits, but the throttlebody didn't and the timeframe prevented modifying this combination to fit with everything.
Old dyno:
Thank you DIYAutotune for your support!
Here are couple cellphone pictures with graph.

A stock Miata makes under 100whp on our dyno. Your standard 12psi GT2560R FMII or BEGi S3 will make ~240 whp.
The straight exhaust and proper external wastegate on Heikki's locost allow the turbo to perform more efficiently than on a standard Miata. He's also .040 overbore, forged bottom end, valve springs, SUBs, etc etc.
This is the first turbo VVT car on our dyno, and it's the highest power BP engine we've tuned to date. I wasn't sure how VICS and VVT would play together, but turning on VICS resulted in a 10ft lb improvement from 3600 up.

1.5 MM overbore actually, block filler used in water jackets up to waterpump to add stiffness .
Wiseco pistons with 8.8 compression ratio after decking and adjusting the squish and compression ratio.
turbo info on my for sale ad:
The compressor has GARRET A/R 60 M24 1-1 on the casting.
The bearing housing has
HJ 01 06J
14411-69F00
466541-1
Turbine housing has Garret 2
turbine inlet flange is 72 mm x 45 mm with holes for 10 mm studs. T25.

Same log manifold made from weld-els used in this setup.

Homemade porting and deshrouding, evening out the compression, milling it clean, +1 valves, Inconel exhaust, Mazdacomp subs, Supertech single spring set. Also made room for bigger cams in the future. Some photos in the build thread.
Trying to avoid high rpm float/7500 rpm harmonics issues with lighter weight followers and heavier springs. The Supertech valves are heavier than stock.
The way the power curve is, I should not spend any time above 7000 unless it is short straight between turns and I can avoid shifting twice.
