All I know about forged internals is they're a lot more durable engine parts and allow you to handle more horsepower. Like I am spraying 100 shot now and would like to go to 150 but I'm told I'd need forged internals (not to mention fuel pumps, rear end, etc)

So what parts in the engine need to be replaced to have "forged internals?" How much more power can you handle? How much do they cost? How much to install?

Sorry for the stupid question but if you don't ask you'll never know. Thanks

 

Forged alum pistons
Forged steel crank
Forged steel rods

 

my buddies run 150 shots on their stock ls1....and they have gonne thru lots o' bottles....

you can run 150 on your ls1 just get a different fuel pump and all the safety crap

 

Can You define "Forged" I think that is what he wants to know and so do I.

 

A forged part is pounded into shape. Because of this, it has a denser grain... kind of like comparing a loose grain wood like pine to a tight grain wood like hickory. The hickory is always stronger. Castings are simply parts made by pouring metal into a mold. Some casting methods are better than others but never near as strong as a forging.

Most parts are "cast" that is where they pour molten metal into a sand casting, let it cool and there you go. The probelm with this is you get inclusions in the metal sometimes, that creates weakeness. Also they are not heat treated typically.

Forged metal uses a quality steel that is heated almost to the point of melting, then it is pressed but huge hydraulics usually, and a set of dies that form the metal, sometimes done repeatedly. Then it is usually cooled then re-heated again to let the stresses out. In the old days they would heat, and pound the metal, then cool it.

That is the basic difference, and why forged metals cost more. How that helps

 

forged.....
to form by heating and hammering...beat into shape

 

Where do you order these online for the LS1? How much for install? I'm guessing pretty expensive. And it's just a forged crank, pistons, and rods?

call em up too and talk to john

tell em henry sent u and youll get a nice price


they have everything and if they dont have it online on their catalog they can get it anyway

 

Feb 2003 issue of Hot Rod magazine has a very good article called "Metallurgy Made Simple" by Marlan Davis. It's excellent, comprehensive and accurate. It may take a couple of readings, but almost everyone will learn something from it.
For the short answer to your question, read the paragraph "Manufacturing Methods"

 

can u view this online?????

 

You can go to Scot Forge (do a search for it) and there is quite a bit of information on the subject.

When would one decide to go to forged internals? (i.e. 450HP?)

How much for an install?

 

prob over 500 rwhp

 

In a very simplified explanation...forging is a process in which one hammers, presses, or rolls metals to form and shape it. At the end it produces a much stronger part...there's a lot of info you can find on the net.
