Baseline dyno done, let the mods begin! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Awesome!
I haven't dynoed mine yet but plan on doing it soon (before COTA in Feb.)
My mods are very similar to what you want except for the 987 airbox, and I have a VR race tune. I also have a 3.2 factory reman engine (2006) with the big bearing, so I don't know if that is 258 HP stock or not. But if it is, I think I'm somewhere in the 290-295 HP at the crank. With 100 octane race gas, it might be slightly more, but it scoots on the track! I think you'll be pleasantly surprised. Not sure though if the 2004 SE tune will take advantage of all those mods. Hope it does!

Here are my thoughts:

Stock 258 HP (maybe more since 2006 was 280HP)
Tune +15 HP
74 mm TB + IPD plenum + 15 HP
Secondary bypass + 5 HP

Total ~ 293 HP crank (maybe a couple more on 100 octane fuel)
And the UDP might release a couple more to the wheels...

Here are some facts: A 2000-2002 engine factory rebuilt in 2006 will be identical to a 2002 engine with the exception of the 2006 design IMSB.

To increase engine power you must get more air into it & then mix in the proper amount of additional fuel. 987 air filter housing is the key component for that.
