will i still have brakes or do i need an external vacuum canister???

 

Why does that cam look familiar? I can't seem to place my finger on it. It will come to me eventually.

It will probably be borderline. The fact that it's an EFI grind will help. Brakes themselves only need like 11-12" vacuum to operate. At those rates, you will need to be careful, but they should work. Plug in a vacuum gauge and take a reading if you are concerned. A vacuum resevoir is a small price to pay for the added brake functionality if that's what it boils down to.

 

lol youre all over these boards arent ya stek! im probably going to grab one but i just cant find a place to mount it in the car!! i already have to take out my windshield washer fluid bottle to make room for the msd box, i guess ill just replace the charcoal canister with the vacuum canister, who needs emissions

 

you will have enough vaccum

 

I agree.
