A 2.3 volvo engine optimised for what point in the rev range, and using what camshaft? What turbo did you assume in your "calculation"
Seriously Phil, you know NOTHING about how to work it out, so dont try and pretend you do, it leads to you giving misleading advice and trying to pretend that its gospel, its not a simple subject at all.
So now you know its a 1.7 engine, what changes will that have to your guesses?
