how much do you want? also, do you know if the tips protrude more than the shorter tips shown on pg 22? i'm unclear on if that change was a one-off for him or they made all the tips shorter at some point.

Rutiger, I PM'd you. You should PM ISS as well, it's probably the shorter tips but they will know for sure.

If you don't mind me asking what was the temp when you put the car on the dyno. The best run I was able to get was a 347 at a cold start. We made 37 WHP when the car was cold. This was off of our production system. The guy at the dyno said he wouldn't believe it if he didn't see it for himself. The breakdown was 37HP Increase at a cold start / 34 whp with a idle run / and 27 WHP on back to back runs. We are going to do the same run on another car in the same place to verify our numbers. All the numbers were done using SAE smooting 5 as the CF and were done by an independent performance shop that had nothing to do with us.

Not surprised at all Janoy.... Great numbers...
The "cold start" dynos will yield higher numbers in every test. Thats a given.
Please see my post #180 in this thread, which talks about cold start dynos.
Your best numbers are represented by dynos completed with the engine @ normal operating temps.

Yes that was stock. And the k&n is the typhoon. I've had a number of cars dynoed there and other places in wa, or, and ca and the place here seems to be right in line with other dynos so I feel pretty good with their numbers. I'll try to get video of the dyno run too. Trying to figure out how to get all three cars there that day but I'm limited to my wife and I as drivers.
