Several people on that magna carta thread regarding the
IPD Plenum wanted to see , my dyno chart on my stock CS run. Here it is. This was a stock run with no mods at all on the car (other than some spacers on the wheels). As you can see, it stock dynoed at 284 at the wheels. This is very high.
My brother was an engineer for GM, and I was talking with him about this being much higher than Porsche would advertise. He told me that occassionally in manufactoring the parts on the assembly line match up just right, causing an extremely tight engine. I am guessing that happened here. It really could not have been the dyno b/c Ken ran his car just before mine and got the same results he got a few months earlier.
I am planning on getting in for a post-
plenum run next week. It will be interesting to see if it adds more than the 10-12 hp others have gotten on highly modified cars. If this thing adds 20 hp at the wheels, it is certainly a cheap $/hp equation.
