IPD + 82 TB worth it?

I have a 2006 C M with 36k miles, Fabspeed catback & K&N filter - considering the IPD competition upgrade since the car could take better advantage of those. I found the IPD plenum @ EDO Performance for $700 & the BOSCH 0280750473 TB at Rock Auto for $157. 1) Are the performance gains worth it for a street 2) Would this require purchasing a new MAF? 3) Will the ECU require a flash or (I've seen some post) Softronic flash? 4) I see some speak to Cobb Accessport ?!?

@docman - I spoke to someone this week who had the IPD plenum and a throttle body installed on a 987.2. No noticeable performance gains, so they wound up removing it. YMMV, though.

Mine had one on it and took it off… imo waste of money… buy headers , best 2500 you’ll ever spend

Foodbiker & GT3twenty10 - Do you know these were 74 mm or 82 mm TB? Also, did these cars have improved breathing via lower restrictive air cleaner & exhaust ? The Fabspeed exhaust was on the car when I got it. The K&N maybe gives me a bit more induction howl, no additional power as far as I can tell. I've also been thinking about Soul catted headers .

Headers primarily will always be the power adder and exhaust will help a little as well. For in take gizmos the only way those help are about 7k plus which we rarely drive and even then hardly noticeable. It’s not worth the money at all imo. The sound is better . A track only application is the only way those items work… high rpm’s . The X51 manifold would be a nice addition… those help

In my experience the RSS under pulley was the biggest bang for the buck, Reducing parasitic drag is an instant torque gain. i noticed no difference in AC or cooling the car, it was a 2.5 M96 engine for reference.

I did the Softronics race plenum pkg on my 06CS yrs ago. Besides the tune it came with 80mm TB and 996/997 plenum. GT3 came with 80mm TB then later 82mm. For 987.1 (non DFI), 80mm TB is plenty. 82mm TB works better with 987.2 (DFI). But agree that best and foremost upgrade are headers (preferably catless). Next would be a tune (Softronics or COBB ). TB and plenum upgrades won't be noticeable unless you have aftermarket headers IMO.

I don't know which size, to be honest but will let you know if I do find out. (Which Fabspeed exhaust , BTW?)

This is probably the way to go. Porsche 987 Cayman Race Plenum Kit Porsche 987 Cayman Performance Parts Race Plenum Kit by Softronic, with over 30 years experience. www.softronicsoftware.com Edit; From the website description, and forum posts from people who have this kit installed, it sounds epic. Less about the peak hp/tq numbers, and more about the mid-range torque you get. The m97 with 10-20% more mid range torque would be epic, which is why this kit is on my list. $2500+ is steep, but the benefits sound worth it. The posts I've read from people with this kit say it's transformative. As in they couldn't live with the car without it, after experiencing the additional power. Full disclosure, I'm parroting what I've read, no direct experience (yet) but the descriptions sound intoxicating.

Ditto

From what I've read, this mod can't be understated. The dyno charts they provide shows a solid 15hp gain (iirc), just with the pulley, which is nutty to me. I have the rss harmonic dampener pulley and accompanying belt in my garage waiting to go on as a result. Can't wait to try it out. Dyno chart from RSS for their pulley just for Augie. Blue is basline, red is with the pulley installed.

I hope you don't think you will be able to feel the different 15hp makes because you won't. Not saying it's not there just that you can't feel it and it's a stretch to say it's 15hp increase. It's a lot like all exhaust mfg. out there that show you all kinds of dyno test results as to how they adds all this hp etc. over the factory exhaust . It's really really hard to beat PSE in sound and hp/torque. A far better and much more expensive is the complete kit from Scott @ Softronics. It add a real 25 BHP and loads of mid range torque This kit includes: Genuine Porsche GT3 Throttle Body Genuine Porsche Plenum Collapse proof four ply silicone turbo grade intake hose reinforced internally with tubing All necessary hoses, hose clamps & install hardware (20 parts in total) USB Vehicle Interface Cable (*) Softronic flashing software Custom tailored vehicle specific performance flash file *This product comes with a OBD2 cable, and software... that allows flashing for only 1 vehicle as it is tied to that vehicle's VIN. This is also a special order item as they are made to order and require parts only available from Porsche.

Lol. I love how you disparage the pulley and "all after market exhausts" but laud the softronics kit. Let's trust softronics HP claims but say that RSS and others are all making up their dyno charts, yup, makes sense.

I've followed enough exhaust and other manufacturers claims to make my statement. I have also used Scott's produces over the years and 25hp with all that included makes much more sense that 15hp by using a smaller pulley. Another area that's grossly overstated is chassis dyno tests. The person running the dyno can use any factored loss thru the drivetrain to then state that the hp increase at the flywheel is xxx or if they want to disprove that product, they go the other way.

There are YouTube tests with and without these items and no hp was gained

I’ve also read and seen a lot of posts about no noticeable power add for the mod

There’s not.. it sounds a little better because you can hear the suction note.. but for the money? No…
