450cfm will NOT give you 1300hp n/a on top of a 565" Pontiac. Not even close.

Same as 414 CFM won't make 1200 HP N/A?

It won't... you need around 460-480 cfm to make 1200 hp na on a 565" Pontiac. I can say I have a dyno sheet that says I make 1500hp but if I don't run the number did I really make 1500 hp?

Agree 100%

So how much horsepower is an engine making if it propels a 3000 lb car to a 171 mph quarter mile trap speed ?

So, since you answered with what seems to be an inaccurate calculator.

I'll ask you this way .... whether you believe the dyno sheet or not.

Doesn't the on track performance back up the HP claim?

You can answer correctly or let it go ....

Did you do the calculation?
What did it show if you did?

The MPH will show what HP was used to get that speed.
(doesn't mean that is what the total HP of engine is)

You can answer correctly or let it go ....

BTW, are you trying to imply that I don't think the 414 CFM won't make 1200 HP?

Yes. And it struck a nerve with me knowing exactly where those numbers are from.

You need to talk to Langer, he's the one who doesn't believe it.
