We will write directly to DeMan Motorsport for the boundary conditions between the engine and IM.
If our system fits and since the 4.5l engines are not jet common, we will need a test car for dyno runs. Any volunteers?
Send a system over and we will do back to back on our DynaPac dyno in house.

I am very pleased you are interested in our product.
We put a lot of work into developing a package that will work with a variety of other engine mods and still offer full reversibility.
At the same time we are not interfering with any engine electronics or sensors so your Porsche guarantee should be safe.
The system avoids all stock roll-cages and most aftermarket ones, if they are not lower than stock.
As said before it fits all 6 cylinder 981 and 718 Caymans.
Regarding GT3 throttle body: If you are running stock air filter housings our system fits.
Regarding aftermarket plenums: If you still have stock runners our system fits.
Regarding aftermarket runners: We will test fit the system on Clubsport runners shortly and will let you know if the higher positioned plenum still offers us enough space.
For all additional questions feel free to ask or visit our webpage: www.goldleafperformance.com or our instagram at Goldleaf.performance.
I’m so close to putting a deposit down and I don’t even have a Cayman atm! Needless to say, probably a first for me to buy a car because of a part but certainly entertaining the idea!
We will test the fitment of our system with the Clubsport plenum on 981 in a week. Taking our 3D models into consideration it should be no problem, but better safe than sorry. If it fits the Clubsport plenum it will also fit your 4.5L engine.
For all those interested, we created a new thread, describing the whole process of the project: from inception, 3D scanning, modeling to molding, production and testing.

We have tested the fitment of our system with a Clubsport plenum on the 981 GT4.
Our system clears the Clubsport plenum, but the collision is with the top mounted MAF sensor on the throttle body.
We are already in the process of mould modification.
Once the changes are made, our system will fit all combinations of aftermarket runners, plenums and throttle bodies.
The complete gloss CF system with all the peripheral pars was installed in the car. Everything fits and works correctly.
The dyno run with an installed system was made, but there were too many variables, because of the time difference between before/after tests.
We are planning a before and after dyno run in the same day in the near future.
Below are pictures of the fitted system in more detail. We are striving to make the fit and finish with Porsche standards.
Video is coming soon.
Do you guys have an idea of what the db levels in-cabin are with this product? I’m curious what range we’d see from cruising vs WOT. Or just across all the x1000 rev ranges.
