If you are looking to hot rod your Cayenne v6, I would simply do a CAI, high flow cat back and a reliable ecu tune.

one last time.

Thank you for the insight,
Cold air
HF cat back
Ecu tune

One final question/input.......Long Glass pack resonators upstream from the suitcase....or tubi exhaust.....or gundo hack?

I would assume this would make the VR6 more rambunctious sounding....and more torque on demand from the start. My impression is Porsche has tuned this out to the maximum without adding FI, or just go buy a V8 or TT if you need more power.

No problem on the small topic detour...if you want a Cayenne hot rod, you shoulda got a v8. The six has a lot of tonnage to haul around.
I use Magnaflow resonators, glass packed mufflers rasp and disintegrate quick.

I probably missed this on the first post, but just clarifying: the engine you're using is basically a replica of the Action Express engine? Are Lozano Brothers building it?

I ask because the car chief of that Daytona winning car is a friend of mine and I was talking to him yesterday about your project. I couldn't remember if you were using THE engine from the DP car, or making a V8Turbo be LIKE that engine. I suspect the latter....

Hi Bob !
Our Cayenne v8 5.0 that the LBP shop built for us is a variant of the Grand Am engine that won the 2010 Daytona 24.
Yes ours will be boosted, so much lower c/r. We accomplished 4,999cc by piston size, iron sleeving the aluminum block, and saved lots of cash by not spending on a spec crankshaft. Cnc billet oil pan, with a true dry sump pump mounted outboard...unlike the factory Cayenne which keeps it inside the oe deep oil pan. That factory oil pan would cost us a huge loss in ground clearence (9"). Wilson built intake plenum, RC injectors, Turbonetics gtk units on msds turbo headers. Like the Grand Am engine, we lock down the variocams.
GrandAm does not allow VVT, and it does not give any advantage to a boosted race engine. The Lozano built 2010 endurance engines can still run as good as or better than the current LS Chevy power .
Porsche internals are very well designed, and go the distance. LBP
says that building a Chevy GrandAm engine costs more than
building the Cayenne v8.
Too bad Chevy seems to have a monopoly on these endurance engines.

...In the Netherlands they are already running race boats with the older 928 gts 32v engines. No doubt the Cayenne hot rod v8s will be running in their boats soon enough !

Radiator came in:





Finally, after several weeks of welding, all the seams are now fully welded:





Here is the mock up of the strut bar braces that were welded in. And yes the wood is only a temporary holder for alignment. The actual strut bar that connects to these braces will be cnc'd from an aluminum block:



AND THE GRAND FINALLY!! WHAT YOU'VE ALL BEEN WAITING FOR... (well at least 14 months for me):

The engine in its completion!

Quick specs:
2005 Cayenne Twin Turbo motor, bored out from 4.5 to 5.0 Litre.
All new / upgraded everything internally.
Wilson Intake Manifold (yes the same intake manifold used on the 2010 Winning 24 Hour of Daytona, Prototype Cayenne V8 N/A powered car!)

Beautiful V8 mill ... How do you plan to integrate the air intake and risers with the bodywork?

Ted, no doubt this plenum will Leave the building !
I plan to trim the Sheridan engine lid (fiberglass) and reshape to suit the final resting place for this intake.
We already have an onboard camera to help while backing up...as we will lose all visibility in the center of the rear window. The leading edge (at center) of the rear trunk will also be trimmed for the intercooler up pipes. All trunk + engine lids are simple lift-off and not hinged.
