    04 impala ss/indy

    a guy i know wants his RPM limiter raised on his S/C Impala SS/Indy. I don't know much about the 3800 motor, and I tried talking him out of it (i don't think it's worth it for a grocery getter). He's a car guy (older cars mostly) and knows the risks, but seems adamant to get it done.

    My question is what kind of RPM's can this motor safely turn stock; and, for my own curiosity, what boost levels can this motor safely handle stock?

    From what I've heard any thing over 6K you could see things let loose.
    Boost, on a stock S/C motor around 6-8 or more if the exhaust is not opened up.

    BTW i have a tune guide for the 3.8 if your interested.
    PM me.
    The Regal has been laid to rest..... rust
    Now have an 06 Lucerne with the 3.8 and wishing HPT would cover that car
    Loved my 2001 Buick Regal GS.
