Sweet, sure nicer than my ugly collectors on the 993TT's. I'm only down 20% on engine volume too

I had a question about your ITB's and "hats". Did you run any trumpets inside the boxes? I've got Jenveys with their tall trumpets and have been trying to determine how I want to do this. Off boost, this might help ramming effect but I think a restriction under boost at max flow. I have thought that the small full radius shorter trumpets like some run on (non-Porsche) ITB's. This would/might max flow and make more pleasant looking boxes above the ITB's.

Also, If I choose to run trumpets how much room over the top would I need to max flow? Would anyone put a turtle above the trumpet to turn air flow?

Interesting, who made those headers??, cheers, Sonny.

Are you mapping multiple tunes: racetrack/fuel vs. street/pump

Tal, do you have any additional photos of engine in states of assembly? You've kept us in suspense for quite sometime.....expecting some impressive 60-130's
