I'm looking for some kind of chart, possibly a form saying "With this size pulley, you will make this much boost". Is there anything like that?

I just want to make sure im going to have the pulley i want, for the boost i want before i get it tuned. thanks

I've started to pay more attention to forced combo threads lately

Soooooooo

It would seem to me that since you got good flowing stuff

You would see less boost than others with parts that flowed less

AND

You would have to use smaller pulleys to match their boost values

Then again

Doesn't that mean boost is less important to you than them

BECAUSE

Your combo is more efficient than theirs

Click to expand...

I don't have a clue

I was just somehow thinking the whole ........................

How much boost thing

Is not necessarily a definite indicator of ............

Power
or
No Power

How about if I try and show what I'm thinking about ...... like this

Would one want

12lbs of boost from ...... iron heads, small intake, etc
or
9-10lbs of boost from ...... a combo like yours

Somehow, I think boost alone doesn't tell the whole story

There is not chart that will giev you what you want. The closest chart is on Vortech's website. All it gives you is blower efficency. You can use this to judge how much boost you will make but, only if you use a few different pullies and compare their boost level to the efficency.
