how much hp to turn impeller?

[LVjetboy]

Aggressor B @ 4000 = 200 hp
That's actual power not rated. Now if you did build that 355 to put out a true 400 hp at the lake...then 80's are possible with your jet.

Hey Jer, what does it say for a b cut in an e pump at 5200 rpm?

I forgot, do you have an Aggressor impeller or is it Berkeley?

It is a legend

[LVjetboy]

Legend B @ 5200 = 415 hp
There was talk about Legends new impeller absorbing more hp...if so I don't have charts for that yet.

Hot damn, Thanks Jer, not bad for a blowd up, crappy iron headed ****ed Over Rebuilt Dodge, that pushes the damn dipstick out when you lean on it hard.

Looks like 338hp to me. It would take 430hp @ 5417rpm for that same boat to see 80mph (I was curious).
Blown 472, sorry about the bunk numbers, I based off berk imp.
