maf and throttle body diameter

[jacabean]

Pedros setup is nice but the cost is as much as the IPD set up. i guess your best bet is to put the parts together yourself.

sidebar - i was snooping around and found a site that showed the 997.2 plenum(hard info to find, as the online parts diagrams for the dfi 09+ cars are not readily available).

what is interesting to note is that the 997.2 plenum has a resonance flap (the 997.1, they one we've been discussing to-date, does not).

to track the evolution of these things, my understanding is as follows:

reason - the resonance flaps stay closed at low rpm to facilitate intake tuning. at high rpm they open to maximise airflow. they tend to activate around the same time as the cams turn over. note that the presence of the flap, even when open, can restrict max airflow, so the flap is a compromise between low rpm and max hp.

986/996/997 - resonance flap on the resonance tube, but none on the plenum.
987/cayman - flap added to the plenum
997.2 - flap added to the plenum

so, for some reason, porsche decided late in the game to add this technology to the 911 series. i presume that they initiallywanted max mid-range for their 'turny' cars, and max hp for their 'straight line' cars. i guess they eventually decided that the 3.8 had engough hp and needed more low rpm grunt.

SO, we've got to ask ourselves - more top end or more low end? if i can squeeze a 997.1 plenum in there, i should be able to squeeze a cayman plenum in there (which has the resonance flap). i'll have to check, but i should be able to tee off the line that controls the other resonance flap to drive this one. then it's just a matter of rigging the aos connection.

perhaps both and a back-to-back comaprision?!?!?

... a full ECU tune.
If you look at my kit and add up the cost of the parts you'll se that it's what you pay for at Suncoast or any other Dealer.
Thanks for ripping me off guys!

Do you really think you're getting ripped off? I just want to get a sense of how serious you are before writing more.

Really?

When I suggested the 997 plenum I was not aware of your T3 kit. Have a look at the beginning of the thread. The idea came from wanting to try a larger throttle body as is used on the IPD product. The 997 plenum was a natural step.

Sometimes others think of the same things you do; it's happened to me many times. Some like to work out problems and develop their own stuff. Keep in mind that as Canadians buying kits and components is frot with customs, duties, taxes and shipping problems; sometimes you get fed-up and want to just do it yourself if you can.

Your kit came to light later, and looks great. It looks like you have it all dialed in. Some may disagree with the design and that is their prerogative. Of course a dedicated tune will be of significant value. Keep up the great development work.

I would think you are getting some free advertising rather than being ripped off

I'm saying that your ripping me off when you imply that putting a bigger tee and throttle body together will be the same and cheaper than my kits (which include a full ECU remap, a new e-gas TB a new technoTorque3 and complete plumbing including silicone fittings and hardware).
I have nothing against hacking and being creative, heck I'm one of the first Boxster hackers!
But let's be honest and compare apples to apples.

Nothing he's doing constitutes "ripping" off. Fitting bigger throttle bodies to a car dates way back in hot-rodder history. There's nothing original about using new Porsche parts on older Porsches. No rip offs there.

If there is a "value add" that you provide over piecing together catalog parts (which anyone can do), then maybe you should play that up instead of taking a negative approach.

I don't understand the apples and oranges comment. This appears to be apples and your potential bigger apples instead.

That's not apples to apples.
The IPD is just a plenum.
My TechnoPower kits include a Plenum a THrottle Body all the fittings and hardware and an ECU Tune.
So if someone looking for information reads that statement and decides to buy the IPD I got ripped off and the buyer as well.
And if you install just a bigger tee and a bigger throttle body and you expect to see any power gains, guess who is getting ripped off then.

Again, if you add value beyond compeditive solutions, then you have a compeditive edge. With that you should be able to justify your price. Comments by others in this thread on the potential results without proof are just speculation, no one would take them as any more than that.

A rip off would be if someone copied your unique parts of the solution. If anything, you've done it to IPD, haven't you?

I have nothing personal at all against Pedro, on the contrary, I applaud all he's done for others in our community. But on this point, he's got no place to say he's getting ripped off by anything contained in this thread.

i have a lot of respect for Pedro , he has done a lot for the boxster community . My thoughts on this topic was to accomplish what the IPD setup does for less money.
using the 997 S plenum , 997 throttle body and some home made connections was what i got from the thread. it could be done for around 500 . I don't see how this is ripping anyone off. does this achieve more air into the engine ? Yes .
the aftermarket needs to understand that these cars are getting old and have passed hands 3 or 4 times and require more maintenance and repair . the people who own them typically have less cash to work with than say a 911 turbo owner. The actual amount of owners willing to drop this kind of dough for this mod. are far and few.
