944 N/A hp figures
How much hp you have take from N/A 944 engines. I just delivered a adjustable cam gear to one person who has a 944 track car. It's an early car without the possibility to change eprom easily. Engine is a stock ROW 944 N/A with heavily modified intake ports. Head has been done one of the most respect head builders here in Finland. With this head they have dynoned 193 hp. Head builder told that with modified exhaust ports they can have easily over 200 hp with adjustable cam gear.
some details of this cam gear
Cam gear installed into my friends 3.0L 951

I have seen cars that had 3-angle valve grinds and port work done with less than 2 HP gained on the dyno. To yield those numbers, you'd better have over 11:1 compression and be running that car on 94+ octane gas to get some belief from the people around here.
You aren't the first person to be laughed at for your claims. I'm just warning you in advance.

by my math youd need to significantly increase the airflow with that headwork assuming everything else is the same.
the stock euro motor flows about 418 m^3/hr at WOT...for 193HP (crank) youd need around 505 m^3/hr. and if its NA id think you might need to stroke it in order to pull that much air in.
maybe its some super-rich fuel and the cam gear is fully adjusted..?

I haven't seen any dyno figures, that's just what he told me. i have no experience to hop up 944 N/A engines, i am building a 3.0L 951, so i am into turbos. Cam gear is not yet installed into this N/A engine. I know this is a sensitive issue, but i have seen dyno figures from some other european cars which has much smaller engines, so why wouldn't 944 N/A engine produce some serious HP figures if engine is built right.

It costs more than it's worth that's why. People have even deleted balance shafts to get N/A motors up to 2.8-3.0 Litres to yield over 190 HP, but they destroyed themselves due to the vibrations.

What do balance shafts and an increase in displacement have to do with each other?

Not going to happend on and 8 valve head unless you do some serious engine work and rev the crap out of it. I have heard of and beleive 183 crank hp 2.5L 8 valve motors, but that is still 10 hp shy. 10 hp is long way once you have already cranked out 20 more than stock on these things.
Oh... I assume you are talking crank hp and not at the wheels 192 at the wheels takes 3.0L and a 16 valve head at minimum.

im not saying its impossible to make power with the 944 NA engine but it will take alot of money to do anything really worthwhile while maintaining natural aspiration.
if you want to really make some more power with the engine, get the most airflow you can from the head, give it some high compression pistons, change the engine management a bit, give it a MAF and maybe try individual throttle bodies with velocity stacks. then run it on the highest octane you can and adjust accordingly.
