Well, if you could absorb the power instead of letting it slip, you would be faster. Can't argue with that, well maybe you can.

Your boat runs fast, (like it should with that power) almost as fast at that larger V hull that your engine builder had.:eek:


I've got customers with single engine Talon's and a lot less hp than yours going mid 120's and no swapping ends. :grinser010:

26Redline,

I have wondered about the prop issue on the RPM cats. They seem to get cavitation burns on the middle of the blades which eventually causes blade/prop failure.. ie they throw a blade.

I thought this might be just on Steves boat/outdrive combination, but sounds like it is a boat issue.

Your thoughts?

Chris

Well lets see...my engine builder's engine was a 572, he had it turning 7400pluss RPM's, and was running 110 octain gas. I am turning 6000-6400rpm's on 93 octain with a 540, and FYI the engine that is in my boat was in Gary's boat for 33hrs, with the 200AX Whipple on it and the boat would only run 102mph, straight from his boat to mine I ran 118-120 with a 34 labbed prop until the supercharged was changed to the 305AX 5.0L Blower:gfight:

Chris,

The prop issue on Steves boat is from the bullet design on the lower, I have not had any problem from the MMW drive doing that to any props, what I am saying about the labbed props, is that with the torque that I am putting through the leading edge of the props start to break after just a few test hrs, I took a custom 34 that Steve had Hering do in Jacksonville, I brought it home from Jacksonville ran it on 2 outings approx. 6 hrs, sent it back to Steve, and ran his boat 1 time and the blades started breaking (sorry again Steve):kiss:

So you are saying the V hull went faster than your?:eek:

Have you ever tried the P5-x's ?

My boat likes them better than the Herings or Labbed Bravo's.

I have the P5-x's labbed by Hering (right up the street from me)

I think that Gary's Howard 28 has done a best of 133mph.

I think this cat will beat that.

Chris

Im thinking you should just that damn thing and buy and new one :party-smiley-004: Then there would be some used RPM's on the market for some of us po' folk :lolhit:

There is a great deal on a used RPM in the Classifieds right now.

I have driven this boat, and it is just pure fun!

Gary's top speed was 130.3, and that was on a bigtime race tune, turning over 7500rpm's and around 1400hp:eek:

Ran several differant P5X, again lost speed and handeling the boat really likes the Bravo style props, I just got one done by BBlades, got alot more cup and a mild labbing, weather has been chit here all weekend, but I will run it next weekend, going to be interesting to see what it does...:drink:

In case you're not aware of who Rik is, he's the man you talk to if you want to buy an Arneson drive. I think you have blown whatever chance you had for doing that...

I know who RIK is and I don't want to buy an Arneson:point:

Ok man that's cool I'm out of this thread cya.

Acually its is a issue with the drive. My boat is burning the prop a little bit with the new sc lower also. Erics eliminator does it also. I think it is the drive design on the lower unit.

Hey John, how was Cumberland??? Steve said he had a great time, it sucked azz down in my neck of the woods, it fukin rained all damn weekend and its still raining, I told Mark about 9:00 Friday night that if we left now we would get there about 7 am, should have stopped drinking and headed yalls way...:lolhit:

The next time you give it a speed run, set the boat and leave it after the run so you can take a pic to show the prop angle it likes.

How about a pic of the prop?

I sent Steve an email for engine centerline to put on the drawing but I have not recieved anything yet. Got the transom drawing.

pat W

Pat I will get you what you need Friday, and I spoke to Steve and he will be getting with you, he was @ cumberland this weekend but will give you all the info you need this week...

Thanks,
Jeff

Check300's Set-up

Adjustable Power :drink:

That is kick ass...I love the Boost selector:coolcowboy:

I like the boost switch. I had a dial and I had a bad habit of turning the dial up and not having the octane in the tank to handle the boost. If I had a key boost selector I woudl have saved a lot of $$$

If anyone is interested my Max Machine Worx is ready to ship, complete drive all new except the outter case all billet MXS drive 1:35 gears, just gone through @ MMW, all new gears, bearings, races, and clutch shaft. total cost for rebuild 5,000 Drive is for sale for 10,000, and that includes shipping in the lower 48:coolcowboy:

Ahhhhhh,.....that stinks.

This is a pretty nice set-up

and the last of them
