I just spoke w/ the people at RSS and they told me that the GT2 already has a fairly large stock plenum, and that the gains from the IPD plenum are really only evident on the TT, not the GT2.

I really admire their honesty, picking integrity over making a sale.

However, the remaining question is, would I still benefit from the larger (75 mm) throtlle body that I could utilize if I had the IPD plenum. They are going to talk w/ Turbo Mike about that one, but I was wondering if anyone else my have some information on that question.

My gut feeling is that my money would be better spent elsewere.

 

Thanks

 

Just take your CTT's TB out for the day and let us know how it works out.

 

My Cayenne's...that is what you installed in ol Tippy, right?

 

Yep, that's 75mm TB that is used in this mod.

 

Dr_jitsu,

Thanks for contacting us. IPD does indeed have an application for your 996 GT2 that works with the enlarged 75mm TB. We have confirmation that it will work and work well, your satisfaction is guaranteed. Thanks again, PM sent.

Got your VM Doc, been busy with work. I will shoot you a PM. You are going the right direction my friend

 

Sean,
get that choking Ep exhaust off your car.. that will do 10 fold vs other things your trying to improve.... at your level that exhaust is choking you up big time.... trust me I know.

 

Mark,

I may I the future. On Robs car at 1K hp the same exhaust did not affect his total power output (1009 w the EP, and 109 w/ your exhaust) but w/ yours, the power came on 300 rpm faster.

 

I thought he had the fabspeed not the EP.... he was not running cats...
here is a pic of what he sent me when I was doing his parts...
