I have heard all over the place that you can get a rough idea as to how much HP by the amount of boost. I have heard that you can figure 10 to 11 hp per pound of boost. If that is true, I should be at about 340 to 375 HP since I can get 34 psi boost. A #8 plate is supposed to be about 230 HP. Can somebody clarify this for me?? I just don't understand............

I think a better equation for hp would be 10 AVAILABLE hp per pound of boost. Meaning if you're building 30lbs boost, you could provide for 300hp. I am building 30lb, but with bad timing and 230,000mi on stock injectors I'm no where close to 300hp, more like about 250hp.

 

The figure will vary from engine to engine, first of all. (I have no idea if 10 hp/lb boost is accurate on the B-motor) Second, it's more like this: Example: My stock engine makes 200 hp with 10 lbs of boost. If I go to 20 lbs boost, how much power do I gain? 10 more lbs @ 10 hp/lb = 100 extra hp.
200 stock + 100 extra = 300 hp after the extra boost.
