I've sent my 964 turbo for tuning.

On the dyno is the right way! Those guys look very legitimate to me!
I would be interested in learning before/after.

On the right is Reinhold Schmirler from Rs-tuning.de it's best porsche engine guy in the world. Jurgen Alzen won 29 titles using his engines. On the left is his brother Gerhard.

No chance to get 500 hp out of these without full conversion from CIS and much more.
Quite the supply of cranks and cams so I suspect you will be opening it up?

Very curious to see the results of this. Personally I'm entirely satisfied with the power coming from my stock motor. Course I've never dyno'd her, maybe I should, Blam could have done something when he rebuilt it long time ago. Didn't write down part numbers on the invoice. Just says "Porsche - cam left" and "Porsche - cam right" etc. Why would he have replaced the cams now that I think of it. Was a bad shift rebuild with orig owner it seems, wouldn't think cam damaged more like busted valve stem but maybe it banged around in there enough or maybe one broke on each side etc.

So. you are talking KW and not DIN? That would put it around 563 HP SAE. On CIS? I don't think so. Everyone I have seen try it made power until it blew up. There are too many limiting factors from CIS and to achieve that much would need to go well above 1.1 bar and then the heads always lifted.
I will be interested in what you achieve.
