I am somewhat noobish to FI and I hope this isnt to stupid but I was wondering.
does the whole vac system see the same boost that the engine is seeing? I would assume so because my boost guage is hooked up to the system via the GE vac mani, so the WG sees that same boost as well. why doesnt the vac line bulge and blow off? it seems like it would in cars pushin 15+ psi. also, I know the brake booster has a check valve but I would think the braking power would be alot less under boost cuz the valve is closed, correct?

 

bump

 

my guess is that even if 10-15psi make super power on an engine... I guess its not really that big pression on the vac system wich dont make it blow... the vac feel the pression but for the tubing its not much.

Just my guess..

 

thats pretty much what I thought but what about cars pushin 25+ psi? and my other questions?

 

I read my vac at the manofold too... good place since its just before air go in the engine.
