    Default I thought of a new invention

    I watched a NHRA Top Fuel motor rebuild, I think they have like 75 minutes to pull apart and rebuild a motor and on the track again. I saw a guy put in CYLINDER SLEEVES in the block. So I'm over at my boat shop guru and he showed me a set of heads that someone had ported to much and put holes right through the thing. SO I thougt why not use the same tech. as the Cylinder sleeves on a block. Just put sleeves in the heads to make them bigger and not have a hole pucnhed threw problem ever again. Or maybe just save a set of heads for more than half the cost of buying new ones.

    Think It would work?? Just a thought you guys so if it's a stupid question I'm sorry ahead of time thanks for your thoughts.

    I've seen heads ported too much on purpose and then epoxied to fix(aluminum, not sure if it will work on iron)... I think that use to happen more often, now cylinder head technology has come so far that there is no need to over port & epoxy...unless the guy dont know what he's doing...

    The Top Fuel engines are built to be sleeved in the pits. The idea was stolen from the Railroad diesel engines. I don't really think your idea would work due to the shape of the ports in a head. They are not cylindrical, but shaped like a "J". Don't really see any way to resleve a port....do you?

    The liberals are asking us to give Obama time. We agree and think 25 to life would be appropriate.

    Exactly. They aren't straight. I don't think it would be possible.

    porting is oldschool. if your porter to say ain't sixty years old find one . they did it back then by trial and error and a steady hand and a love of sitting on a bench for two days grinding iron

    Have any of you guys seen a Top Fuel dragster Head. Off the hook and doesn't look very J looking to me. Maybe I should do some homework Billly and build my own heads. I know there has to be a better idea just waiting to unfold. JMO

    The j shape on a cylender head helps speed the air up as its entering the combustion chamber. A strait port will work on a blown aplication better than a N\A aplication. Now hurry up and invent this and buy us all beer.

    Even on a top fuel head it wouldn't be easy. Anyway very few of us work on top fuel motors and if you can afford a top fuel motor you can probably afford to just buy another head if one gets ruined.

    OK OK OK I see your point. I was just Thinking thats all. Maybe you could help me out a little Billy, there has to be a way to do this. I guess it's just me, I have alot of dreams and thoughts on things.

    Like building a new Jet Pump that could get these boats of ours to very high numbers without having to spend alot of money on HP for a motor.

    Any ideas with this sleeve thing would be great guys. Thank You
