Default Faeflora's Dyno results GT3071R @ 20psi

Like the title says- GT3071R @ 21psi.

93 octane

On the street in 5th gear it hits 20psi at about 3900RPM.

Is your turbo still complaining after you removed the oil restrictor? Nice numbers.

It whines a little but it's doing just fine. I listened to a bazillion videos of ball bearing turbos on youtube and it sounds just like every other one. Since removing the restrictor, once again, it spins for about a minute after shut down.

It feels very smooth on the street. With the timing advancing as the RPM builds it just feels like it's accellerating faster and faster.

Some interesting information regarding my turbo and the tune:

We started the tuning session at base boost which was 15ish psi. That made 300hp and after messing with the VVT map, netted around 320hp. Going to 17ish psi pushed the turbo into it's efficiency range and took us to 370hp. As Phil mentioned in my build thread, going to 21psi only took us to 398hp. My AITs were not increasing at all so basically that indicated my **** just wasn't able to flow very well over 370hp. Consensus of those attending was that my log manifold was the bottleneck.

BTW whenever leatherface shows up---

Finally, I think at 20psi my car is actually faster than yours was in your videos.

so what all the kids say about running beyond 7300 seems to make sense on your car.

considering your power is dropping off after 7k, i wouldnt add the extra risk factor of 8k.

Yeah the dyno was set to shut the run down at 7400 which is why it shows that major drop but it's actually not falling off like that. We set the dyno limit a little lower to ensure it records the run. Ideally it looks like 8K RPM would be best which is where we set the rev limiter (you don't want your peak power at your rev limiter).

I'm not a Miata specialist and I can't confirm the problems many warn about above 7K RPM. I raised the RPM limit based on customer request and it definitely takes advantage of it. There won't be any VVTi induced valve contact as I pull the cam advance down very early as it picked up much more midrange power that way. He does have upgraded valve springs and valves so as long as the sprocket itself doesn't come apart it should be reliable.

Thanks,
Phil Grabow
