Would anyone be interested in seeing how far Fabspeed can push a 2017+ 718 Turbo? Doesn't seem like a lot of action out there in pursuit of making these turbo cars into complete monsters. I mean...what are the limits of the stock components? Let's strap a BIG Turbo on......some meth..larger intercooler...a wicked tune...one Recaro...and see what happens. Maybe it will be a GREAT SUCCESS!

Is t there a limit on what the manual transmission can handle? I was under the impression that it was the reason the manual 718 s/GTS weee limited to 309 lbft of torque while the PDK one got more or could handle more. Obviously I don’t have an official ref for this. Interested in hearing ppls thoughts.

I'm definitely interested. The constraints I see are heat management, the manual gearbox (as mentioned above), and the lack of community experience (as you point out). I'm not sure we'll know the limits of the transmission really well until we solve heat soak. My hot rod is an RX-7 LS2 swapped and the primary problem for them is heat management. So, I'm reluctant to go big with the Cayman until we have more experience with mitigation heat soak.

Do we know what other higher horsepower cars Porsche has used this exact manual gear box? Could extrapolate on the limit of the gear box a bit from that. This has also been a limiting factor in me considering a tune for my car.

From the APR folks it sounds like the fuel system is currently the limiting factor. Not sure if its the injectors or HPFP or both. I'm sure an E85 tune would be nice power pump without having to run race gas if you could get the fuel volume.

I like that idea....

The limiting factor for me is that guy in front of me. And to be honest, me. If I was tracking, well then maybe.

I've got a Softronic flash on my Cayman GTS. It's supposedly 435HP with no extra geegaws to add and put up with. It certainly has more power and it's a lot of fun. Still civil when I want it to be. I'm happy with it. I did the install myself in my garage with my laptop during a quarantine/Covid scare. It doesn't have a selector box or anything. You just get more when you want it.

I got a GTS because of the front radiator. I think the extra cooling is a good thing for even occasional track use. Always leery about mid-engines and track days.

Scott is a peach! He does software on Porsche prototype race cars and the like for AG. He has really good access to Porsche's codes and his stuff is very nice. I had one on my Gen 1 and liked it, so I called again when I got this 718.

I like the features of the APR but you have to go to their shops to have it installed. I'm not crazy about that...and I was in the mood for a project...going a little stir-crazy around the house.

I think a good "next step" might be a Soul down-pipe, but I don't imagine I'm ever going to take it.
