That was not a Porsche engine, G.
Thats why I said 10.5.1 wont be an issue.
And yes, many on this forum would say I am crazy.
I feel many people trying to make N/A power with their porsches dont do enough
work on their cylinder heads. Thats where you make your power.
I had a 3.3L Holden Six that made 300hp with pump gas.
Thats a old australian design engine from the 1960s. (crap)
But with a great head on it and 3 55mm webber carbs and 10.5 comp thats what it made on the dyno. I kept the comp low so I could run a 100hp NOS kit on it.
Plenty of people know more than I.
However I also had an 820hp 336ci chev on carbs, no super charging.
Thats 2.4hp per ci.
Same as a 3.2 porsche making 450hp on carbs as a comparison.
So I feel I know a bit about making N/A power.
