With that being said how come you don't have the ap plenum???It sounds like you think its a better product... I think yllwturbo is speaking from experience of having the IPD so his experiences mean more than than just someone asking questions on both threads!!!!

First it was this....

then it was this...

Then finally it he admits he's talking about 997gt3.. come on guys!!!

Do you see anything wrong with a vendor misleading people or not???

 

I'd like to see a subjective (Independent) tests and comparisons of power gains of any and all companies offering these;

a. Stock as a control
b. Aftermarket Throttle Body on oem plenum
c. Aftermarket Plenumy with oem throttle body
d. Aftermarket Plenum and Throttle Bodies together

I have a theory that the majority of the gains are from the throttle body, but it wouldn't be conclusive without these numbers. This would also have to be on the same car as any header/exhaust mod would more than likely increase the incoming airflow as well.

Any takers?

 

since you call it as you see it, then you should agree that all dynos can and should come under scrutiny if they are going to be used as evidence of performance improvements... as is data being thrown around by sponsors, vendors, users all alike. It's always been like this, if you're going to say your part makes 10 hp, prove it... and let the people question the validity of the claim. Mods aren't cheap and if you post a dyno, you better be able to back it up. And yes, I know the Dyno wasn't Vivid's. And yes, I am still a happy Vivid customer, i was talking about various 75mm/78mm/82mm whatever numbers are thrown around, if they aren't accurate, then people will point it out because it's the correct thing to do.

 

We made the 997TT plenum with the CTT throttlebody. We decided to use the same CTT throttlebody and make a plenum for the 996TT so we only had to stock 1 plenum. On a stock K16 car, using the 997GT3 or the 82mm throttle body would be huge in diameter causing a loss of power download and a gain up top. Because I dont use anything other then the CTT throttlebody, I might not know each size. All I really care about is what product I am using and working with. We choose for the smaller TB to give more drivable performance. This was our preference and if you go back to Page 1, you will see why and what we did to build this. Then on Page 3 you can see our Product Test here.

Nobody is misleading anything... This was never a IPD vs Agency Power thread. Each have their own benefits. Whats funny is the other thread with BBI.. Betim and I are friends and have talked about both of these threads and how out of control each have gotten. To yellowturbo, I dont care if you like EVO, IPD, BBI, or whoever, I sell all of their products and have a good relationship with each. For a guy that calls me up and says, "hey bro bro, how you doing bro bro" and then drives out here to spend money with someone else and I still give you free rear toe links cause you though it would be good to weld a rod end, pretty ungrateful.

Good luck to you and your car.

 

Still in denial.... its really sad!!!! still can't admit...

 

I dont know what is being denied... I really dont. Since your so vocal, here is the number - 4809663040 x222

 

If you don't see what you did (wrong measurement,misleading info) what is the point for me to talk to you on the phone and waste my time. You would look better if you admit your mistakes instead of trying to find ways to beat around the bush and continuing this bs!!

 

I did not measure anything wrong. Look at the first 3 pages and then post on page 6 or 7 that I attached a caliper measurement of the stock TB. I measure both at the same spot. For the misleading info, your just looking for a fight, I never mislead anyone. Good luck with your car!

 

On page 6 what you measured was not accurate. Here we go again with the misleading info. This is not a stock throttle body size for 996tt. The stock throttle body is 68mm measured at the SHAFT NOT 75MM.... (more misleading information again) When are you going to stop.

 

I'm not sold on either plenum. I personally think the throttle body has more to do with the extra power than either plenum design. I am glad that you like to hear from ONE persons experience instead of asking questions. That's the difference between a general consumer and an analyst.

 

Wrong. .The ONE experience is myself since I have the IPD. Please enlighten us when you decide to get either one after your research.

 

It is obviously to late to enlighten you, since you already have one, and thus have a stake in positive results.

So what was you dyno graph before and after? Or 60-130 verified before and after? or 1/4 trap speed before and after?

There are others that I have talked to privately that don't post about their experience.

 

It is to late to enlighten me, you are correct because I have been enlightened already by feeling the difference in power after the IPD was installed. I have not taken the car to the track or anything after the y-pipe and IPD mod but from what I felt after the install it was a big difference.

Sorry I won't be able to compare between before and after because I'm also doing a Alpha 3071. I'm waiting for Evolution Motorsports to return from texas mile so I can take it in for a re-tune.

 

I hear that a lot. It definitely feels like a big gain from many. I guess that is all that matters. I also understand the dyno issue as I haven't dyno'd my mods before and after, even though I wish I had. If I do either of these I think I will dyno, however.

 

The exterior is smaller than the 996tt, however the interior diameter is larger. In addition the floe is balanced between all runners.
