I know what you are saying you need to spend money to keep up but what about us guy's with the smaller boats we do not want to run against 30' boats either and I do not want to build a lower HP motor to run in the same class I will stay home and watch my grass grow.
Tyler why not put a 496 in and run the class? Power for power!You have the newer technology (hull) but that would be fun! Dukes could also stay and put that power and I bet you would all be close.

So if class 6 is for boats under 26' foot with 600+ hp, where I am suppose to run?

It was not that long ago that the bat boat would run against F1 boats (500-525hp) competitively. Now I am being told that Class 6 is a 600hp class with almost the same boat as the F1 although no weight rule. Thus an F1 boat is at a disadvantage in class 6? This is getting too complex.

Thus let me ask a different question (a personal one). It was my intention to replace the shot engine in my boat with the 383 Stoker that Mercruiser is putting out (350 at the flywheel, just like the 377 offered). Is that a bad choice if I am going to run class 5?

Should I get a pumped up SBC? I know of a host of dry sumped late model race engines that would (detuned) give me 500+. Or shoudl I just go to a SB2.2 at 9 to 1 pulling 750+ (you know one built by Childress and/or Hendricks)?

I am still confused how a single engine boat with 600+ hp should not be running P4 though. If an F1 can run 80+ with a 525, how does one with 600+ justify running anything lower than P4.

Please help me understand.
Because it is all about accelleration now in P class racing. When F1 ran it was about top speed in the class if a guy out accellerated you in a corner you just drove by him on the straight away. You can not drive by people on the straight aways on a certain speed and GPS (right Chris)!!!!!! So if your boat only will run 80 with your biggest prop your accelleration is dog$hit. Now drop down 2 or 3 pitch sizes and turn the engine a little higher RPM and you have acceration but now your engine does not make power with the added RPM so now you drop back a class and prop the boat and RPM to fit the class. You could put the Hendrick motor in it probaly makes peak power at 9000 RPM I am sure you can find a 7 pitch prop off a sail boat to match the RPM and power range and top speed of the class. I built my engine for the 70 MPH class I took in account my rpm I would need, engine size, Piston speed, rotatating weight, compression, rod lenth, bore size, port size in the cylinder head for velocity, camshaft to match everything I just listed including header diameter and length. My motor was built so my RPM's and prop and rev limit ran right at 70 MPH it is not as simple to raise the RPM and prop size on mine and be competive in Class 5 I would lose my accelleration because the engine was built and dynoed for 70MPH.

Rick,

Having run my Bat Boat with a 377 in OPA Class 5 I would say if you want a chance to win at every OPA race, you will need more power. Put a blower on it.

Everyone needs to man up!!!
Brian Hollis offered all you guy's with the stock power a class last year with a 10000.00 prize purse and nobody stepped up. Everybody complains about the big power in the smaller classes that's what it takes for acceration to win. OK limit the power to 500 HP and I will build a motor that out accerates your 500 HP and that will be the next complaint. If you want all the boats to run the same everybody will win nobody will lose.

I don't blame any P-Class guy that runs a big motor and little prop , they're only going by the rules. I just wanted to clarify that.

Tyler,
Now you are contradicting yourself. You first say that we need
big power to get the acceleration to win. Then you say if we
limit power to 500, you will build a 500 that will out accelerate
everyone else. Why not then limit the power to around 500HP
and the guys that can do their homework will still have an
advantage, but not as big a one?

By the way, this is in no way a attack on you and your
championship. You have done your homework and followed
the rules. I just see this thing escalating. No one wants to
repower their boat everytime someone shows up with a bigger
bullet.
