I have still never seen a 816.8 at 28.5psi dyno sheet but only a 616.8 dyno sheet at 27.5psi. And I will call bullshit from the rooftops that he picked up 200hp at the same rpm by adding 1psi.
And I've met the owner. He's a nice guy but he knows "Jacques Merde" about his cars. He pays a shop to do whatever and call him when it's done. That's fine, but I'd rather give props to the guy that built it.

What is odd is the that nitrous will make more power on boost than naturally aspirated. So I would really think they would want to confirm that **** and not just rely on estimation. If it was really a 200 shot it would probably result in well over 200hp gained.

Its also about how power comes on.... big turbos are surprisingly easy on drivetrains compared to a smaller turbo running the same power that comes on like its on a switch. I.e. if you have a delta of 250ftlbs surging over a few hundred RPM when compared to normal loads, your going to have some problems, be it tires or drivetrain.

I'll add to the DIY thread here.... Im Hella Busy.... lots on the go. The Miata manifold market is loving my work... I have a few hotside kits with exhaust to finish and then I have 2 more manifolds and downpipes as well as an intake manifold to build.

So much argon, so little time.

There's no gears to strip off in the 1:1 ratios. 3rd in the 5 speed and 4th in the 6 speed are just the weakest gears in the set, thats why they break. It doesnt matter how abruptly the power comes on, its all about the torque being pushed through the gears causing them to fatigue fail.
There has to be a "gear" of some sort, but the ratio is 1:1 with equal amounts of teeth.

It may not be Hellafab, but Hellafab had to start somewhere. Keep it up. A lot of us who can't fab anything at all like this, whether because of lack of tools, or talent, or both, like to see creations by mere mortals

Next project will be back braces for the ultrashield seats I bought. Hi_I'm_Sean cut me some pieces and tubing so I can match what he did. Sadly the TIG I used is back in portland so these will be welded with my HF shitbox.

Did you ever end up using a turbo crane or anything to take stress off of the manifold? Did it ever break?

Pretty sure I ran across yours somewhere along the way in my research. Wayne_curr, wittyworks, and sturovo were pretty much the main resources. They have some incredibly helpful stuff out there.

Never broke.
What I did have a serious problem with though, was flange warping.
Both the turbo and head flanges warped twice. I re-surfaced them and they still warped again.
No idea why. Bought the flanges from Weirtec, they were 3/8 iirc, guess I shoulda gone 1/2
