Did you install the berk cats? Which y pipe did you install? I'm assuming the 18 hp berk dyno was too optimistic??

Outperformance Shop - 2009 Nissan 370z Performance Parts Evidently my car was the first one to try the JIC Y-pipe and obviously the test monkey for fit as they're not on their web site yet. The Y-pipe is extremely well made, the welds are fabulous and fit perfect. Will do a bit of welding myself on occasion (when and if I can get my hands on a welder) and was very impressed with the work. Top shelf stuff. (so are the cats) Rarely have I been able to duplicate manufacturers results as you always see "best case' outcomes. As mentioned, the was a 9 hp difference just in underhood engine temps and heat soak. Makes it pretty easy to add a fudge factor. The other issue I'm having is going through a learning curve on what the car likes and how to best dyno the car for consistency. That's OK. I'm learning. There may be a little bit more power from the cats and Y-pipe, but frankly that is about what I was expecting. The radical change in fuel/air was not expected and has taken me back a notch. Dan is the owner of Outperformance and he had a great next move suggestion: Remove the stock exhaust section after the Y-Pipe, dyno and see what the effects are to determine how efficient the stock exhaust system is. Think that is a great idea as usually on modding a car the first thing I do is make sure plenty of air is capable of going in and out eliminating any weak links. Once I'm comfortable no obstacles are present, then focus at other areas. |
