Pre - IPD Plenum Dyno Run Results
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.

The Tuner at the race shop I spoke to said those dynos generally read 10% to 15% higher than a calibrated Dyno and even more than in Porsche Cup certification mode. Well at least you can still measure the delta change and get a reasonable result because a 10% error at 20HP is only 2 HP. Good enough! Look forward to your result.

wow yeah I just noticed that 232ft lbs. is very low for a 286HP engine. I have 24 more ftlbs. but 13 less HP.

gforce,
I have 06 Cayman S manual, de-snork, Milltek headers & Milltek Cat Back, Evo V-flow filter, Snapflash and IPD Plenum. Next is Under Drive Pulley.
Ive pretty well run out of bolt on mods to do now except for say X51 manifold.
Im not interested in turbo, supercharging, engine swap or engine dismantle.

Well now I have 301HP and 261LBS of torque so Ken has 10HP more with more mods but 10LBS of torque less. IF I do an intake and plenum I should be the highest NA Cayman S here. Ken has the highest HP but I have the highest torque. Intake and plenum should boost up my #'s.

Ummm did we all forget that you cannot compare one dyno to another?
Also I haven't done a post plenum dyno run yet I could be at 400hp for all I know...

The 10 more hp and 10 more lbs of torque isn't enough of a gap to really brag about, regardless of the dyno.... jmo

I know its not but 1HP is an increase in performance, It may mean the engine is stronger but it doesnt mean the car is faster. The way a car performs is up to the driver. But again 1Horsepower and 1Pound of Torque does mean the engine IS that much stronger.
