    Default TCM 1100s

    I was wondering what water pressures should be at 3000 , 4000 , 5000 and WOT . I don't know if I can shave some off the pickups to lose drag. DCB said they look long and to confirm with you what pressures should be before I trim them. I think I'm seeing about 25 psi at 5000.


    BTW I LOVE the motors !!!!! I've put almost 25 hrs on them and they run great.

    Paul, did you call TCM? Eric probably has those numbers off the top of his head.

    I would think at high speeds as quick as its picking it up, its spitting it out...

    I don't see a gain of any more than 1mph from trimming them and the possibilty of hurting the engines does'nt seem worth it...

    You could go this route...

    I think Pauls' point was to determine if he already has a surplus of water pressure, which he could cut down to gain some speed. Small things make BIG differences at the speeds his boat goes.

    Think about this - the pitot tube for a mechanical speedometer is about 1/4" wide, and normally sticks down about 1-2" in the water. Removing that is good for about 2mph at 100mph!

    Pauls' boat runs almost 150, where it's likely a bigger factor.

    I completely understand...

    I'm just a little confused as to why he'd mess with anything just to be able to say his 32 runs 157 instead of 154...

    I could see looking for that extra 1-2 mph if my boat was a contender to be known as the fastest of its make/model but not when there are hand fulls of other F-32's with more power running in the 160's and even one into the 170's...

    I think Paul's 32 is a Dialed Piece as is...
