Was talkin to Russ earlier and we somehow got into the topic of */C.. and it made me wonder. Is there some kind of boost controller ( Maybe that'* not the right term, something similar to maybe to Boost Timing Master? Well something that does what boost controller does )..

So in essence.. lets say there'* a */C that can boost up to 15 PSI for a specific engine, but have some kind of limiter allowing to boost only to 8 for now till the internals are strengthen to handle 15 PSI boost @ a later date.

P.*.

OK.. other then altering pulley size

Your PCM limits boost via the BCS and BCA. The MAP sensor is what it watches for reference.

Sorry.. I guess I should state that it'* non 3.8L related.. is there any kind of aftermarket kinda thing for any engine application ??

You could try varrying the resistance to the BCS input with a potentiometer or some resistors.

Why... what are you trying to do Drifter?

Nothing .. just thinkin out loud.. humm.. Eaton is only good for XX boost and isn't efficient..

A good */C thats on a centrifugal type system may yield better boost @ lower temp.. but then why spend so much for it just to give same boost?? So why not go for the gusto and get a bigger */c that pushes higher boost right?? Well we know the internals of N/A or others can only withstand so much before upgrading the internals is needed.. but that will cost also $$ So why not just get a big boost */C.. have some form of a boost controller so it won't kill it ( And limit the boost for now ) till sufficient $$ can be saved to upgrade the internal to utilize more boost and full potential of the new */C..

Russ brought up a good point that Boost controller is for turbo'* only.. but wat bout */C ??

err...

STOP THE OPPRESSION OF TURBOS WITH SUPERCHARGER !!!

Mmmm....I think......I shall respond.

Upgrade to an MP112 supercharger or get an IC.

mmmmm...... MP112...... <drool>

Didn't do much search into it.. but the 3 sites I"ve been to says for Corvettes and such.. :* but how would you be able to limit the boost of that */C?? Obviouslly in any engine that'* not as big of a displacement or made to handle it will blow. So leads me back to Boost Controller for */C Apps..
