he briefly touches on what seems to be some slight trouble he faced with tuning one of the 4.5L converted cars. What seemed to be the problem? (if there was one). Apologies if i'm assuming too much
My woefully under educated guess would be that it has something to do with knock. Per Matt's previous podcast, Betim, from BBi, stated something to the fact that Porsche pushes the boundaries with engine knock, from the factory. ECU is constantly adjusting to provide max power, given conditions. Given that its a moving target, maybe pushing the envelope with more displacement leaves a fine line for applicable maps?

hmmmm interesting for sure. He seemed to be dancing on his words a bit there. Would be interesting to find out what he was dealing with. Only bring it up as someone who is more than likely going to be a future 4.5L convert myself . I do live pretty conveniently located down here not too far away from the M-Engineering South Florida shop as well.
Oh yeah, they made mention the compression ratio changes with Rick's 4.5 as well...so there's that. I don't know...that guy kinda lost me at the beginning when he said tuning was a black art, and nobody knew what they were doing with Euros in the 2000s. Is he not aware of all the "chips" that were developed/sold by the likes of neuspeed, GIAC, and et al, in the 90s? I had custom maps in my Corrado when I had "Deman-like" motor built. Or was he just referring to newer ECUs?
Oh, oh, yeah...then there's the "well, 4.5L 6-cyl breaks the 500cc rule" thing...harder to stay Stoich? Probably also contributing to tuning difficulties/limitations...and the need for Boostane/98.

Yeah I was a bit surprised by his hesitation in the interview regarding talking 4.5l. I wonder if this is somewhat connected to why other companies have limited to 4.25l vs also going up to 4.5l.

Regarding the bolded comments above, is this on the podcast, what time stamp? I listened a couple of times and must have missed it.
That's probably one of the reasons why AP said 4.0 is the limit Porsche wants to go...especially revving to 9k.
Perhaps, certainly that is a very large 6-cyl to be built to survive on the street with a 9k redline, talk about a very fine balance!

Yes, I found it, thanks!
From what Mitch said there and what Matt said Rick told him about the need to run Boostane it sounds like the compression ratio on the Matt's 4.5l is so high (to get 565HP) that the engine would not survive at 91 octane or possibly not even 93 octane, likely detonation would result. Possibly also why Rick told Mitch not to go there!
I find this interesting because in the past Rick has built and supplied customers with 4.5l that were mapped for 91 (Cali) or 93 (east) and with as expected with lower maximum torque and HP, but when I asked him in the DeMan thread if these optional configurations were still available, he did not reply.
