Just out of curiosity, why is there a noticeable dip in power @ ~4700rpms?

 

How high did you take the rpms? It looks like you stopped at 6500. I used to shift mine at 8000 and never had a problem. The power will start dropping off after that as the turbos run out of breath. Good dyno nonetheless for a motor rated 280hp at the flywheel.

 

I didn't notice any at all. If you notice, the dip only occurred on the 2nd and 3rd runs at which I tried upping the boost. I started to run into an issue with the diverter valve at that point (13psi) due to a loose secondary vacuum line. I'm still debugging the issue but may just end up going with a BOV.

The rev limiter on the ECU dumps at 6500rpms as I was in 4th gear on the dyno. I'm not sure what I rev to in 1st/2nd gear but I'm pretty sure I rev higher. I'll check it out next time. I can't even remember.

I used to rev my Prelude H22 to 8k even though redline was 7.5k. I knew where the rev limiter kicked in exactly!

 

no no no....300 is not enough haha ...........its nice bro, looks and speed is nice too though!! so good luck with the kit, your motor is very clean right now.....but the single would be soooooo pretty!!!!
