Intake plenum and 911 throttle body

[930turbo]

I've done a little research on the mods I posted about earlier. It looks like all of them are a long slide for a short gain; headers & exhaust for $4000-ish for 6HP, intake mods for $1000-ish for 6 more HP and a tune for $800 for about 6HP more than that. 18HP is a lot but $6000 is a lot more than that. Can anyone share their experience with these upgrades? What's the seat-of-the-pant dyno results? Should I just leave it alone? There has to be something- or a combination of things - that softened the potential of the 3.2 S, the specific output is considerably lower that other models of the same era.

That's a crazy high estimate for those particular mods. Divide it by four-ish, perhaps even more if you buy used as I had suggested to you earlier here.

To illustrate further, here's another idea for your consideration: http://986forum.com/forums/boxster-cayman-parts-sale-wanted/73389-sale-fabspeed-200-cell-986-header-%96-new-never-used.html

By the way - Out of respect for Ben's thread, you would be better served to start a new thread on your topic, rather than to continue to be off-topic here. You will likely gain a lot more traction and interest.
