bbywu, why so small?
I would think if you were going to upgrade you would at least want more than 10,000 horsepower! lol |
The dyno results from RSS's post are interesting. What they show is a significant gain in the 2200 to 5000 rpm range. High rpm gains seem to be minimal. The improvements in the low rpm range are what you will benefit from in real world driving. The plenum may also allow the boost to come on more rapidly.
For about $1500 installed in a $126K+ car, this is very reasonable in cost. |

Dang. Calling another man's turbo small. And Jason talking about a stiff chasis...I feel emasculated. ;)
Believe me, that certainly wasn't intentional on my part. :rolleyes: |
^^don't they say that a man's car is just an extension of his........AHH OOOOO GUH! hehe!

Here are a few pictures of the IPD plenum pre-install
Cast metal http://jasontang.virtuality.org/albu...0904.sized.jpg Looking inside, painted and designed with efficient airflow in mind http://jasontang.virtuality.org/albu...0907.sized.jpg Compare that with the OEM plastic plenum http://jasontang.virtuality.org/albu...6638.sized.jpg Not designed for airflow efficiency http://jasontang.virtuality.org/albu...6639.sized.jpg The view of the inside from the top http://jasontang.virtuality.org/albu...6640.sized.jpg Close up of my engine compartment with the OEM plenum removed http://jasontang.virtuality.org/albu...0277.sized.jpg Engine compartment without OEM plenum http://jasontang.virtuality.org/albu...0279.sized.jpg New IPD pleum in place. Notice that the cast metal matches the intake manifold too http://jasontang.virtuality.org/albu...0290.sized.jpg Another view of IPD plenum http://jasontang.virtuality.org/albu...0291.sized.jpg It took Cantrell Motorsport about 2.5 hours to install the plenum which should be pretty standard for tuner shops everywhere if they know what they're doing. My initial impressions although done before the ECU has had a chance to relearn the new parameters of the airflow efficiency brought on by the new plenum from IPD/RSS is very good. From a standstill, there's a noticable reduction in turbo lag when moving from a standstill. The engine seems to be slightly more eager to get up to speed. Bottom line is, I'm very happy with this modification and will definitely recommend anyone considering this mod to go ahead and get it. I have no plans to do a dyno at this time since I didn't have a chance to do a pre-dyno test. I should be able to compare stock vs modified soon if Larry gives me the opportunity to do so. I'll give a final report after the ECU has had a chance to adapt. BTW, I have the IPD Plenum on my 997tt and absolutely love it. Haven't dynoed it yet, but my butt dyno tells me it's there everytime.:D |
GotBoost, it's pretty easy. Go to your Photobucket account, find the image you want to post in the size you'd like. Right click on it, then highlight/copy the address that shows up in the <url>, once you've done that, come back to make a post, click on "go advanced" and then click on the little icon that looks like this https://www.6speedonline.com/forums/...nsertimage.gif and paste the address in the dialog box that shows up. That's it. Try it out.

Great write up! and Thanks! i didnt know were that thing was hilarious
now my main concern is heat ? how is it compared to the factory plastic piece ? after a few runs i mean ? Thanks |
I was wondering what parts had to be removed in order to get at the stock plenum?
I'm not considering doing this myself, but I was just wondering if this mod would go well with other mods that someone might be considering. |

So how much HP are we looking at for this upgrade?
Also how many hour labour for install? |
[update]: It's been almost a week since I first got the IPD installed so I've managed to put a few miles in my Turbo since then. I can tell you guys that after about 50 miles, the powerband has noticably changed for the better. Previously there was a slight dip on power delivery going from a stop but that "dip" has disappeared! Although there's still a lag from a complete stop, it's not as apparent as it once was before. The plenum has definitely worked in ensuring a smoother power delivery throughout the powerband. I would give this "mod" two very enthusiastic thumbs up!

[quote=RSSGREG;1703585]Greetings 6 Speeders,
We just received the dyno chart below from a customer with a EVT 700 Big Power Kit. It also demonstrates how effective the plenum can be with extensive modifications. (See page one.) Greg, This chart doesn't do much for me as you say the plenum here is used with a big power kit and that it demonstrates its' effectiveness with extensive modifications. What does the plenum do without extensive modifications? I suspect very little. |
