Not having any problems with my bds intake at 13 lbs of boost. I have a very consistent boost number through the rom range. I’m pretty sure it would be good for maybe at almost 18 lbs of boost. After that a better intake would be wise!

OK….Stan or anyone else teac us non knowing people ( in English) about boost.
The more you make the more hp you will make providing your engine combo will take it but at my level it’s all the same! Or we can start a new thread! GTO George |

How many times does this need to be said, It is mass air flow that counts not boost. Read what Jim said again and again and again until you get it. Stan

Something like: 12 lbs boost of 'X' mass air flow is 'Xhp' (George's car?) 12 lbs boost of 'Y' mass air flow is 'Yhp' (twooldgoats car?) 'Y' has more mass air flow than 'X' so it would have more HP ('Yhp') than 'X' ('Xhp') If 'Y' ran more boost pressure it would increase HP a lot more?

If you put stock RAIV heads on your motor, the boost # would go up but your power would go down. Boost pressure is a result of restriction. Use better flowing heads and intake and the boost # goes down but the mass airflow goes up. Pressure doesn’t make horsepower, mass airflow does. More air, more fuel, more power. Simple. BTW, just trying to help you understand, not dissing you in any way.

How do you get more air…. More boost. There is a reason NHRA limits boost on a pro mod car….hummmm. GTO George GTO George |

Well put. You have more patience with explanations than I do.

NHRA does not limit boost on roots pro mod cars. Only overdrive %.
Which would make more HP? Or would they be the same? Your motor with a 671 making 10# of boost at 7000rpm or your motor with an 871 making 10# of boost at 7000rpm? Boost pressure is equal. You seem to be hung up on boost pressure as the most important factor. It isn’t.

With a 6-71 on your engine probably couldn't get enough boost to make the same HP as the 8-71. You may have 20 or more pounds with the 6-71 but not the higher HP. Then there is the cam selection, intake selection, RPM range, etc that would dictate the boost also for the amount of HP.
