Greetings Again,

First off, thank you 4by4 for jumping on the dyno and posting your results. We at RSS greatly appreciate all your efforts.

I would like to make 2 very important points.

1. The overall graph is still very consistent with our dyno graph. Power is realized throughout the entire rev range, which is pretty impressive considering most mods deliver gains up high OR down low. So your NET power gains (Not MAX power gains) are really quite nice.

2. We claim that the IPD plenum will provide an additional 24 hp when installed on a STOCK Cayman S. As we all know (or maybe we don't) as you climb the proverbial "Performance Ladder" horsepower is harder to come by and gets more expensive. You will ALWAYS get greater hp yields on your car with your early stage mods than if you install the same mods during the late stage modding process. If you have 4 mods, each claiming/delivering 10 hp you do not get a combined number of 40 hp.

9, or 12 hp gain is pretty damn good considering all the other mods that are installed on the car. Ken will probably see similar gains on his car. Now, all we need are the independent dyno results of the IPD plenum on a stock car.

I hope this sheds some additional light on the subject. Thank again to 4by4 and everyone else for their contributions.

Cheers,
Greg
