The dyno is great, lots of our customers hate-it though..... they feel it's too stingy... LOL
It's very repeatable and has a ton of cool features like simulated grades, inertia-only runs, and a ton of logging channels and features that we are just barely tapping into. For now, it's working great for back to back turbo testing!

Today's Test: S364.5 SX-E with 68mm turbine with .83 non-gated T4 housing

Great to see you doing all these dyno's with the same truck, and on the same dyno.
Really cool to see how much difference there is between the different turbine wheels and housings.

Only thing that could have made it any better, is if the drive pressure was recorded for each housing as well.
:rockwoot: Seriously though, thanks for doing these runs and vids. Just sitting and watching and trying to soak it up.

Yes, much more to come, just killing us timewise to edit down the useless video/outtakes...
When Todd and I started Power Driven, we hated not having data/information when we were first time performance consumers, so one of our company goals is to provide free information that will make both us and the consumer better at selecting performance products.
Sorry about the current lag in videos, I promise, we've got a ton more left to upload!
We do have a JGS drive pressure filter and permanent drive pressure gauge mounted in the cab, maybe we can get an in-cab camera setup to record boost, drive, and egt? I'll look into it for future videos. I will say this, all of the combinations that spool fast, go north of 55 psi drive pressure as RPM climbs above 2800 rpm or so. Drive pressure is very RPM dependent on these turbo/housing combinations and usually runs 5 to 10 psi higher than boost till you hit that magic choke line around 2800 to 3k rpm where drive goes up to 60 psi and boost usually starts falling a couple PSI.
We want to see the information as much as you guys do, so you're more than welcome.

There should be a way to make these videos...hell, even this thread, a STICKY!

At this time we have not tested or planned to test the .80ar gated housing on the 68mm turbine, but I can add it to the request list and we'll see if we can make it happen. We're getting a lot of requests to see our new "towing" compound turbo setup in the same test sequence... :ft:

Comparison between the ball bearing charger you guys made against the SXE's possibly?

Can someone explain why such a focus on the 68mm turbine? Its the same old wheel as the s300sx. The whole sxe300 frame benefits around in the design of the 80/74 turbine. Obviously the turbos map grooves and race cover lead to gains aswell.

Likely the stigma associated with the previous clipped version of the 80/74 turbine.
