max boost on stock internals
max boost on stock internals
if i was to hook a boost controller up to my 06 ss/sc what would be the max amount of boost i could fron safely with complete stock internals...
you can use a boost controller to limit MAX boost, like for example putting on a 2.6 but wanting only 15 psi.
but with hpt i dont see why u would.
as for amounts u can push, a 2.5 gets close to 20lbs but then u need mad cooling to support it YO

i understand that its not a turbo car i was just wondering if i was to start regulating my boost what the max i could push safely off stock internals...
im still running at stock boost but i was just wondering if i could raise it ne and what i could take it to and still be ok or would it run better leavin it where its at?

with the M62 in truth once you go above 12 psi it starts losing efficiency.
after about 15-16 psi its basically a cute little herman nelson.
its not the boost thats killing our stock internals, its the heat.

so its not really gonna matter if i raise my boost ne? without puttin a upgraded cooling system?
well to answer your question, max boost on stock internals IMO is 15psi with a stage 2 pulley. max for the supercharger itself is 20psi but I've seen blown motors from boost over 15psi so i'd stay away from anything higher than that.
ah i c ...so i cant take it up ne without changin the pulleys regaurdless...? that makes since...im not puttin one on it was just a question that one of my buddies brought up and was wondering if it would work...i am thinkin bout the stage two at the moment, what do they s2's run on boost?
If you put a boost controller on it (which you can) you would only be boosting at most 12.5 psi. You need to swap the pulley, in which case 17.5psi is what you can run safely. The gaskets can handle about 22psi, but your pistons can't take that heat from a 20k+rpm eaton.
hmmm i dunno man. i know theres other things at play.
but i think its nearly impossible to dispute that the superheated air from an overspun M62 causes alot of problems.
care to elaborate? im always willing to learn more

someone like forever ago did a whole write up on it, im too lazy to find it. has nothing to do with boost
oh my what a dumb dumb
you couldnt be more wrong sir!
this engine can handle alot of boost, heat is a killing factor, or RETARDS

the efficiency range corresponds to around about 15psi.
i guess i should have quoted RPM values....but you know what i meant.
pumping 160*+ air into the engine causes problems.
hence why everyone is excited about the harrop blower swap.
effieciency ftw.

the efficiency range is in the 14000 rpm range which is a 2.8 at 6800 rpm

Past stock boost is even bad. People go straight for the pulley when they should be doing exhaust and intake mods first.

tell me what that says, and you will have an answer.
there is a way to overspin the blower well past it's efficiency range. most people do this with failed success. compressing air regardless of how many "psi" you run still creates heat. the stock efficiency of the m62 is 7 psi. this does not account for the after cooler.
does a smaller pulley produce more boost, horsepower, torque? yes. i have dyno sheets to prove this. does it also create heat?
**** yes it does. this is where people make major mistakes.

Retards are the #1 reason these cars blow up. Anyone who knows what happened to the guy who bought my Cobalt SS knows what I am talking about. Too many people buy a car for the wrong reasons, and with a lack of experience or responsibility.
