The pre 725 block needs significant modification to the oiling system and much beyond 800HP the #5 rod begins to starve for oil. Once corrected the engine can take ludicrous levels of power. Alexi at boostpower can build a blown Ilmor that will stay together. UD

BTW- Eddie.....do you have a sister? Uncle Dave

Seen lots of good AND bad press about the Bmax, and I like to know more about it. Somewhere here on OSO there is a great pict with three of them across the back of a rig all blown bad..... At the same time.... I've been using Imco stuff for 20 years and have multitudes of quality parts form...

Also note - the lifter galleries are closed. UD

Not sure, but I think externally side bolted mains is an expansion control technique as much as a strength thing. I would guess the caps are ductile iron. Expansion with alum caps in an aluminum (alloy) block would be too much and the engine would lose oil pressure when hot- iron main caps...

The quality of these parts is fantastic. I havent seen the old block to compare, but the new piece is a work of art. Uncle Dave

I have a Teague Platinum upper with an Imco lower. Its a high quality product, and Bob Teague stands by his warranties. - but 900HP on a lake- maybe. On the ocean- no way. Its basically the same as an Imco SC. I just did a rebuild at 54 hours. I "hit it" with an Ilmor 710 and a 5500lb...

Totally phat. UD

I would think it would-simply based on less parasitic loss- -- but I dont really know. I cant find a current switchover thats "like" my setup. Ill read up on the velocity in the meantime. UD

Any other stepped hulls than the u39 boat? UD

Ill poke around the other three sites. I dont see squat here. UD

Can you post the links so I can go see some picts? Id like to read up on the threads. UD

Id like to see some picts of small single engine v's running an Arneson. Single v's running surface piercing apps can have strange handling characteristics. Twins no problem. I think that certain ASD's can run standard bravo style props, which may mitigate this issue somewhat but not fully...

The arneson is indeed cool. Are there a few smaller (under 30ft ) single engine v's with Arnesons? I would be interested in seeing them. UD

Shavings on the magnets. UD
