Jamie will do the same kit for 718 GT4?

A/S

I posted data somewhere with 60-100mph and 60-130mph runs before the Dundon Intake upgrade and after, my car equipped with the Dundon Quiet muffler and the Dundon headers.

Where the car gains are truly noticeable are from 6000rpm to 9000rpm. Normal driving with the new intake would not change, and the intake noise from the side entries is reduced a bit. But a high RPMs the thing performs amazingly well.

When I tested, I benchmarked against my 991.1 Turbo S that had a lot of upgrades, pushing anywhere from 640hp to over 700hp depending on which tune I was running. On the 640Hp tune (93 octane off the shelve Cobb + Inconel headers + Inconel Muffler + No Cats + IPD TB + IPD Y-pipe + IC), the GT3RS from a roll (running a Vbox and a draggy) would beat the Turbo S from 60-100, and only the 60-130 will the Turbo S get ahead by very little. I would run these tests from 30mph in 2nd gear and commit to full throttle, then extract the data at my office to compare. Same roads and same days.

Without doubt, the best performance upgrade to make power in a 991 GT3 is the whole intake/exhaust Dundon system. No ECU tune needed, no Check Engine Lights, awesome sound, and vastly better acceleration. At my local track (PBIR) I had no problems walking away in straight line from modified C7-Z06, AMG GTR, Nissan GTR at the back straight.

If there were tens of thousands of 991 GT3s out there, Dundon could offset the R&D costs into more production units and set the price lower. The Dundon upgrades are worth every penny, I see a lot of modifications that carry a similar price tag and add little (wheels + paint correction + paint protection as an example).

Maybe, have Jamie setup a Group By once a year around the holidays for these awesome parts.

Mine is coming off my car this week and will be available for sale for those who are interested.

I’m in for a group buy! Once I start sniffing around an upgrade like this, I know it’s just a matter of time.....

Great question! I also want to know to result for HP gain of Dundon's intake combo without its full exhaust package since I can' t find its power gain figure from Dundon's website! Hopefully I can get the answer from your question!

Thank you for bringing that up with my same request!

Please PM me with info.

I’m in for a group buy on the plenum intake upgrade (assuming a good deal). Jamie- please do some pandemic pricing!

Would you mind sharing why? Did you experience something which turned you off to it?

I have the above mentioned parts removed from my RS and ready for sale if any of you are interested hit me up. Packaged and ready for shipping from Portland,OR.

Selling RS in stock configuration. Otherwise, fantastic mods for the platform. Amazing performance with amazing sounds.

This is a great system and anyone who is looking to get it should jump on the set MR965 has for sale. I have driven a couple of GT3RS with this system installed. It makes a huge difference in how the car pulls on track in the upper RPM range. You can feel it pulling all the way to redline harder than the stock cars run. I bought the system just this past month and will be installing it this winter

We typically recommend for folks to get a good suction wave from the exhaust. Akra is only about 5-6whp at high rpm so not a very powerful suction wave on the 991.2 GT3/RS.

How the intake works is by removing the restriction and allowing atmospheric pressure to get as close to the intake valve as possible, this way when the valve opens and there is a negative pressure (vacuum) in the cylinder from the headers, there is a large driving force to push air into the cylinder. It's the pressure difference from in the plenum to in the cylinder that allows the intake kit to "make" power. If there is only more atmospheric pressure in the plenum, and not significant suction in the cylinder then the effects of what the intake kit can do aren't as dramatic.

On a 991.2 GT3 with our street headers we make 20whp with the intake kit
On a 991.2 GT3RS with Akra we make about 12-15whp with the intake kit.

It all helps and the amount the car loses power past the 8200 rpm peak is reduced substantially.

Dundon generally doesn't do sales. What I can do for this thread as there does seem to be interest is I'll post a code good for 2 weeks and the links to the various intake packages for the 991.1 GT3, 991.1 GT3RS, 991.2 GT3, 991.2 Touring and 991.2 GT3RS. If you don't order before the code expires...



718 GT4 the intake is aluminum, and we're betting Porsche has something up their sleeves for the 718 GT4RS. We're going to wait and see what is coming... Then make something.

Mike's kit is for an RS only, if you have a touring, a 991.1 GT3 or a 991.2 GT3 you need a different kit.

I'll post a code in a separate post.

see above

Will post a code, you'll have to go to the cart to see what the % off is, not going to post it and please don't repost to others... I'll cancel it if I see it. Too often we post a special price on Rennlist and someone see's it 9 months later and somehow thinks it's still available.

Depends on options and the car. Full Exhaust/Intake kit for the GT3RS is 15-20k. Dual Cone Airbox and 93mm TB/Plenum kit is $7990
