Intake plenum and 911 throttle body

[eddy]

Wow Ben.

I put 200 miles on the car today. Pulls much harder across the rpm range. I'm thrilled with the results. The quality of the piece is clear to see when you look at it, but the proof is in the pudding, and I have to say the pudding is pretty good.

I am headed back to the dyno (hopefully next week, waiting for a time from the shop) to verify the gains. Once that's done I will post about the install. Cliff's notes: 987 box is a pain (we knew that) Ben's Plenum is easy peasy; I also came up with a decent way to attach both using existing silicone piping and a bit of aluminum pipe. Stay tuned!

After switching coils, I'm still pulling the P0306 code. Car wouldn't rev pass 2000. I unplugged the MAF and it revved fine. So next thing is I'm going to pull the MAF off another boxster and try it out. So heads up, if you pull one of these codes, unplug the MAF to see if it clears up the problem.
