Hollywooding yeah I know the feeling of overtaxed, after all it does take alot of power to run a laptop.... I mean the newer motors...


lmao

2wld4u hmm, you know 24 volt systems would be better, as it would take alot of power to control the selonoids accuratly....I just figured 16 volt because it the next obvious step above 12v.....most 12 volt systems today are over taxed if you ask me but when and how long are differnent storries...maybe by 2010...and by then we will proboly have a 70's flash back and be in a gas crisis...lol

Hollywooding why 16 volt? almost all Cat's are 24 volt, in fact most heavy duty apps are (komatsu, jd).

2wld4u I think ford has played with some prototypes with selonoids, I alo read one time that a motor with stock internals turned 10,000 rpm with this type set-up....I think it was in a engine builders mag...a few years ago...there was even talk of being able to use carbon fiber valves because of no spring pressure....Its definatly in the works...but we proboly wont see it until cars are converted to 16 Volts....instead of out dated 12 volt systems......

Found it (sorta...)

Cat HEUI System

OK I was way off, but i knew there was something that was all about the timing and precise control.

Poke around there you'll find more detail in the site.

Sorry to get your hopes up, but hey if you got nuthin better to do with diesel, there you go.

Hollywooding What you just said is not so far off 2wld4u

In the new diesel motors cummins or duramax (sorry cant' remember) there are solenoinds that operate the valves, yes you would be able to do just that. And at this time it might only be heavy duty apps however it is very true. no cam, timing chain, pushrods, rocker arms. Just a set of solenoids ontop of the valve that fire when the computer tells it too.

the applications are as endless as the solenoids max firing rate and bottom end. Slick!

I'll dig around some books at home and try to bring a website back for everyone to look at.

Of course the engines they will sell you will never be this big, lawnmower size more than likely.
hmm...that means that 383 im building would make 1532HP!!!!! and a 502 would make 2008HP that is impressive....but, not as impressive as a top fuel car just imagine the kind of cylinder pressures a nitro motor makes to generate 6000+ hp.....but @ 30$ a gallon hydrogen seems a whole lot more attractive...lol I do Have a question, an all ceramic motor....how would you control wear? and I suppose the heads would have selonoids to control the valves and no need for a cam, chain, lifters....that would be cool, punch in on a lap top the lift and duration cam you want and go racing....then punch in a mild manored cam for street...I want one!!!!!

Mikey123 well to start off with the 4.3L chevy has different rods than any of the other tradishional small block chevys, even including the 3.8s the 305 knock off, they are the same bore and stroke, even the rod length and wrist pin is the same, however the rod journals are not, they are larger in diameter than the rest therefore they will not interchange with the rest, Secondally the diesel usually makes more tork primairly because of its size and because of stuffers ( blowers-turbos)however they suffer from rpm range which limits gear selection favorable to having any power at high speeds without having 20+ gears or highway gears which limit take off , and they are set up that way for a couple of reasons, most heavy trucks need power now not when they can rev up to it , lower rpms mean better mialage,and in order to stand up to high tork loads on the bottom ends they have to be built quite large espically the berings, large and wide diameter berings will keep oil suspention better than small narrow diameter berings will, however the big stuff creates way more friction at higher rpms thus causing bering melt downs sooner in the rpm range. see ya mikey

2wld4u Im learning more and more every day, It just goes to show just how complicated the performance world is..........And without this great forum I suppose Id still be left in the dark....lol

gt2betubbed 2wild, I thought the same thing as you. BUT! In reading 4 jaw's post, I realized that there just a lot more to it than going 500 past the peak HP. From what I read, I figure the best way to find out is to go from a dyno print out and take it to a track and test.

They would be if you could shift an infinite ratio transmission fast enough with no slip...and pumped enough boost into it. Try running 60 psi of boost at 21:1 compression with gasoline, only diesel is capable. Just because race rules favor gasoline dragsters does'nt mean a diesel couldn't run with the big boys, take away nitromethane and diesel would rule.

johnsongrass1 How fast can a runner run if his legs are faster then...

How fast can a runner run if he's carrying a 2:73 gearset...

How fast can a runner run if he's pushing a diesel...
