Now I'm now expert, but from the hands-on-a-dyno sheet/apples-to-apples-research I've done, the Carrera manifold can be solidly said to add about 40hp. There....I've made the commitment.
Of course it depends on several other things, but if you had to isolate, this is the increase. BUT.....more than that increase, you have increased CFM ("flow"), and above all - equal distribution to each cylinder.
512 is kick-a$$ power.
Do you have a picture of your 930 to post, Bruce?
Since I've also had a ton of work done at Chris', I must have seen your car at some time...
