I thought this may be useful to some folks looking to build a ka-t setup. Seems there aren't a ton of detailed posts with dyno information. I believe when done right these engines have great potential. This engine took some serious abuse this drift season(Apparently I am the 4th owner of this engine since built as well). 10/10 I would recommend anyone going the ka-t route. Anyways on to the details.

This particular set-up made 326whp @14psi on a roller dyno. With very conservative AFRs. On 93 octane pump gas.
As you can see below the power fell off pretty hard at 5500 rpm. I attribute this to the turbo being slightly too small. The intake manifold could have also been restricting airflow. (Please add your thoughts below)
This was a pretty affordable route in my opinion. I will be upgrading the turbo to HX35 this winter. I'll update with a dyno chart and let you guys know what happens.
