Look at the last page of that GPONA thread.. the middle port on the vacuum tree doesn't bypass the rotors

You need to use the vacuum line in the LIM to make sure the seafoam doesn't contact the rotors and strip the teflon coating (which will greatly reduce the efficiency of the M90)

Ok, so in the pic above... it's incorrect.
Time to do some googling


*edit*

after searching with newer info, BBE, is this correct?
I found this in a thread that had nothing to do with seafoaming but its the only other vac line under the supercharger that I could find.
any help great appreciated.

 

I believe you on the location of the vac lines. The only thing I'm confused on is I've been lead to believe that seafoam ,although it cleans, doesnt corrode. I know on higher mileage engines the grime is usually what is holding them together lol. I'm having some trouble seeing how 100% petroleum would eat away teflon, I see how it could lube the super charger too much and cause it to damage itself, but actually eating away teflon is a bit mind boggling.... Either way im not puttin seafoam in that line again :P

 

You are assuming Sea Foam is purely petroleum based... and it's not. It contains IPA.

So running SeaFoam across the rotors has a similar effect as Alky injection which is known to strip the coating off of SC rotors

Ah I see now. Well I apologize if I came off as rude, I just wanted to know a bit more. Thanks for the info sir.

 

like those taillights....had to reseal the factory back one on my 02 GP...they all show water seepage in them....i don't find the Pontiac 3.8 series11 as good on fuel as the chevy....good ol' hand slap has cured many problems over the years <grin>

 

Is that why everyone seems to give their vehicles feminine names?

 

Zzzziiiiiinnnnggg!
