Great work once again, Bryan!

I cannot wait for you to receive the billet version!

very nice work

This thing is spooling, and making the power. Very nice. It's making power about 300-500 RPM quicker than my 2.3L GT3076.

I know it's not possible, but I would LOVE to see what this car does on 91 octane.

Yes. The spool is awesome and it puts a smile on my face as I'm in the early stages of a 2.3L build and I'll need a very suitable turbo. My only concern is what do you fellahs recommend as a minimum to strengthen the drivetrain as having that much torque could be an area worth addressing, right?

Is there a ballpark figure of how much difference in spool between BBK Full and this? 300 RPM? 500?

Here is BBK Full vs BBK XL boost plot from last testing session, both 3rd gear:

^ It looks really close to the BBK Full. Since they use the same turbine wheel I would say no more than 200 rpms...

*Edit - Like I said. Thanks for the graph Bryan.

Great power band by the way. So you think that v7 with the larger maps really helped out? Would you happen to have the boost plots for v5 vs. v7? Sorry for all the questions Bryan...

*Edit - On a side note... The M2s are prob not helping the power band. With the built motor has your customer been interested in the FP5Rs or S3s since he doesn't have to worry about valve clearance? Even the S2s would help out a lot. Aaron did some testing between the S2s and M3 and he gained like 30hp I believe.

Great work Bryan

Mikey

Nope this is the highest we have set the boost so far.

The V7 resolution difference has helped a ton with tuning timing. I find I can run more timing in different RPM areas then I could with the lower resolution because of the ability to fine tune the sensitive areas. This is even more apparent on pump gas 91.

I've noticed the evos love running the biggie maps if tuned correctly.

Yes I would imagine this car would make more power with a more aggressive cam but I believe the owner wants a nice tolerable street car.

Man the more info that comes out about this turbo the more excited I get. I can't wait to see final production dyno sheets for this turbo on a 2.0 and 93.
