when i posted it there, i did the same as i did here. went to the site i found the product from, copied it and pasted it. i did the same when i made the thread here. its not a big deal. this shouldnt have even come to this level of discussion.

now, you know im no tech. ive never built a motor in my life, so dont beat me up over this question........ what makes forged pistons and titanium rods so much better for a blower or turbo, then the regular parts in the car now?

It's basically in the difference between casting and forging. That article has a pretty good explanation of the different techniques and their advantages.

to run a decent amount of boost, say 8-10 lbs, would forged pistons and rods be enough to keep from any issues?
im running 460 to the wheels now and im planning on adding a pro charger. ill be looking at close to 600 rwhp. is there anything else needed?

To combat heat, you can:
1. Get a cold air intake
2. Tune for the boost
3. Get an intercooler (and make sure lots of air flows over it)
4. Get spark plugs with a lower heat range.
5. Reduce compression
6. Get headers with equal-length primaries and otherwise improve exhaust flow
7. Get a "boost friendly" cam
8. Make sure your cooling system (water pump, coolant, radiator, fans, and anything that affects airflow to, through, and from the radiator) is up to the task
9. Oil cooler, larger oil pan (with cooling fins!), etc.
10. piston oil squirters (the oil carries the heat away from the piston)
To withstand heat, you:
1. Use higher-octane fuel
2. Install forged pistons
3. Install titanium intake valves and sodium-filled exhaust valves
I'm assuming that an intercooler (maybe two) and a tune are already in your plan. Make sure to change the spark plugs too. If 8-10psi is your target, then yeah, forged pistons are basically a must.
Most of the rest of the stuff on the ZR1's list are not to handle the boost itself, but to add even more power or to handle the increase in power. This is where the lightweight forged crank, special flywheel, clutch, etc. come in.
Forged steel rods (or titanium if your budget supports it) will help handle the power and will reduce rotating mass (which frees up some power and makes the engine rev up more quickly), but this isn't a boost-specific thing. If the stock LS3 rods can handle 600hp, then they can do it whether there's boost involved or not. Do some research to find out what stock LS3 rods can handle -- I'm not sure. I suspect 600hp is nearing the limit. If you're going to have the engine apart to swap pistons, I'd seriously consider doing the rods while you're in there if the budget supports it.
If you're looking at 600rwhp, that means you'll be making even more power than a ZR1 (but with higher loads, due to more weight and worse aero -- which means more heat). If you want your car to be as reliable as it was from the factory, then I would try to do everything on the ZR1's list, and maybe more.

as far as the list goes, i have an intake already but it depends on which blower i actually decide on, as to what intake i use. if i go with magna charger or the ls9, i can use my airiad. if i get a vortech or procharger it already comes with a intake. they all are intercooled. i have long tube headers already. the car will be tuned by backstreet performance. im not sure my cam is "boost friendly". they told me it was when i got it, but ive had other people tell me its not.
id like to do the titanium rods. ill probably do this whole process in steps. i want to prepare the motor for the blower before i put it on. i want to do everything right that needs done , and not just put cheap parts on just to do it all at one time.
i know the heat will be a big issue, id like to even get a hood that has some sort of heat extractors. i know it might not help that much, but it will help cool the engine compartment down a bit.
