It's king of hard to compare both systems in any of the drawings I have seen. maybe someone who has worked on both can add to the discussion.

picture below shows side by side of the intake plenum. the part that I was focusing in is the additional butterfly in the plenum in the "T".
it's opeation is controlled by electronics and vacuum. I don't think 986 ECU has this feature and therefore compatibility problem

I got the unit installed in my MY03 base a few weeks ago. Did a bunch of timed runs in 4th gear from 2000 to 4000 RPM both before and after over the same road within about an hour of each other in the middle of a sunny day. The times averaged 3/4 of a second faster after the install. Haven't seen a downside to it yet - did a DE event on the 26th and really noticed the extra acceleration.

Now for the "seat of the pants" stuff: seems like the engine idles more smoothly, very low end torque seems better - less likely to stall from a standstill, maybe has a little bit more "growl" during acceleration (or maybe it's just the mind playing tricks).

Good information, Dave! Do you know the length of the "run" or the speeds at start / finish for the distance?
How do you feel about price vs results?

It's a simple install. Didn't take long and for the money it's low on the cost for benefit in my book (at least for a Porsche

). Not sure on the speeds or distance, I was so intent on watching the tach with my passenger to make sure the timings were as accurate as possible. Ran the same road in the same direction for all of the runs trying to keep the variables down. Did 7 runs both before and after to make sure I was getting good timings.

A dyno would have been nice... but I don't have access to one. This is the best I could think of to try to take a reading on if there was an improvement.

Just cleaned my throttle body and installed my Techno Torque2. I haven't quite buttoned up everything so I haven't yet driven it.

Does anyone know the purpose of the oddly shaped piece on the tube from the air box to the throttle body? It is close to the throttle body end.

Thanks,

ddb

Got mine from Pedro yesterday and installed it last night so I haven't had the time yet to put much mileage on...only 50 miles or so as of now. And now it's up on jack stands while I flush brake fluid and wait on new pads to get here Monday. But next weekend is the last DE of the year and I'll report after that. Assuming the weather doesn't freeze us out!

Nice pics ddb...looks exactly like mine! Oil, dust and all. lol Mine was a little dirtier than yours, but it cleaned up well. I was also wondering what the odd shaped piece is for. Is it a muffler/silencer sort of thing? I don't know.

OH....be SURE...positive.. that there are no air leaks. Double check the rubber fittings on each end of the tube. I had a small leak that I couldn't see, on the bottom side of the tube. The fitting hadn't seated well. WOW.. the computer went nuts! Car started, but wouldn't idle. No power, no throttle response, backfires. Wouldn't hold a speed. And it threw several cel's. I only went a few blocks but that was enough. Came home, undid the hoses, reattached them making certain they were dead center on the tube. Magic...it runs like a top.

Just a word of warning if you happen to get an air leak. The computer gods are NOT happy.

If you're talking about the wart in this picture, it's a muffler to help meet European sound abatement ordinances or the like.

It's just a sound baffle to meet TUV standards and make it quieter.
Happy Boxstering,

I would hypothesize that this could be made to work for owners of 03-04 cars by installing the necessary plumbing and electrical connections and flashing the DME to a 9X7 map. Highly doubt it's worth all the headache, however.

Thanks ... one can see that they are not compatible. Was hoping though ....
