okay so i have a 2001 pontiac grand prix gt 3.8.
I have gotina 3800 pcm tune, a set of pace setter header and a 3 inch exahst with a magna flow high flow cat. no resinator.
I also have a cold air intake and a alternator booster and tb spacer, these two things i dont know if they did anyhting or not. and i also have msd coils. out of all these how much hp shouldi have gained? and what are the benifits?

maybe 10-15?
Too hard to say really.
On a side note, I'd go back to stock coils, those MSD's are a pointless mod and will give you problems someday.

alt booster and tb spacer are also pointless mods. You should cam it now

cam would be awsome, would i need to get new top end and bottum end parts for the engine and a retune? also what could the msd coils do in the future? i really thought theyd give a better spark

ThisImagination is more important then knowledge.

He means, use the search bar.

MSD coils are known to be junk.
But you'd know that if you searched around and see what others have done.

i havnt read anything bad about them, but okay
08-28-2012
i have never heard anything good about them for grand prixs atleast ive seen on tons of muscle cars though
08-28-2012
in a way its strange but theyre two completely different typs of cars i guess. maybe it just gives out to much voltage then needed?

Righto.
Long story short, they degrade quite quickly, and cause high rpm failures.
Quality product? Don't think so.
As for reason behind failure, no one has looked into it.
Though dwell tends to ruin coils pretty quickly.

ha well you learn somethinge everyday, i have new stock soil packs ready to go on it anyway, ill just resell my msds on ebay.
