Flywheel or Flexplate

[Taylorman]

I will be running a A3 aluminum all season @ no more than 5500rpms.
You can buy 4.285 Aluminum impellers for the price of one Stainless.
What brand A3?

How much power do you have ???
Thius summer, with the thru-transom headers, I should pull 400HP without the Sniper nitrous plate (replaces the 75HP MMM setup from '79), another 100-150HP. Next year's porting on my heads (BBC open chamber '049's) with valve up-size should net me clost to 500 HP total according to the head shop that does DuaneHTP's. The nitrous will then drop to 100 (if not already there) and stay there. Close to 600 HP total by spring '07. My budget won't let me do stuff all at once.

And I don't plan to forget how to pedal her when necissary.
Hmmmmm Somehow that just doesn't look, or read, quite as "right" as it sounds .........

I am guessing there are 4.285 aluminum impellers in the cost of 1 stainless impeller.

Now your talking a multi-stage pump impeller.

Jim, who want's the head ache, of changing out impellers on their boat, or pulling it apart to check it out. It's like point's ign vs Electronic ign, you want to change points every 10,000 miles or not. Just some perspective, I pitty the people who break because of lack of proper maintance, and go out beating the crap out of things. Aluminum. Bronze, and Stainless all have their places.

Once the flywheel sucks the power from your engine, it has to be decellerated to release it. Sounds counter productive in a boat.
Oh yea its a flexplate!

How about letting off the gas in the air. Little cheaper in my opinion.
I did that but when you load the pump again is when it tears up parts.....

I don't have a set back pump it takes about 1.5hrs to change the impeller. But I am very curious to see if the impeller has cav burns or the suction housing or anything else. I also like to check my thrust bearing, being I put tons of use on the boat. Hell I have never went 10K without a tune-up of some sort. I mean When always shooting for optimum performance you have to check and tune. I mean I only have 478K on my stock untouch engine in my truck and it gets better milage today than the day it came off the showroom floor.
