S5 NA air pump issue "no cats"
S5 NA air pump issue "no cats"
Ok I've searched and searched and searched, here is my setup so lets get this out the way
(RB header, Straight pipe, custom single exit exhaust) no split pipe.
My situation is the rear support bracket on my air pump is cracked (over tightened and snapped)
Before I had a S4 and removed the air pump and installed a BOP with a dual pulley on the alt, so in theory I went ahead and purchased the same items and decided to go with it.
Now after searching I found that if I do remove the Air pump the 5th and 6th ports won't function properly because of the VDi is electronic and is operated by the Air Pump and not by exhaust back pressure like on a NA S4.
I am starting to get upset because my car is down and snapped a few belts because of the air pump being off a bit and I don't want it to continue to slip on the water pump.
So my questions are can I just run my dual alt pulley and leave the air pump on without a belt?
Say F it and take the power loss until I figure something out?
Or Should I wire open my 5th and 6th aux ports?!

And by the way, you won't like the performance.

You should buy a replacement and fix the air pump.
And you should also buy a torque wrench so you won't break stuff.
Good Luck!
