Re: Does a bigger turbo housing increase boost?

It ran great before fixing the two issues: replaced headgasket and turbo housing. Then during reassembly, he saw the open port on the intake arm so he capped it. Then during test drives it was...

Re: Does a bigger turbo housing increase boost?

Re: Does a bigger turbo housing increase boost?

Re: radar detector hardwire?

I was basically trying to explain that continuity is the inverse (opposite) of resistance.
A resistance of 0.00 is pure continuity; and a resistance of 1.00 is NO continuity. And yes, I agree,...

Re: radar detector hardwire?

Yes, the continuity setting is different from voltage. Continuity is the common name for resistance, which is measured in "Ohms". Use Google if you want to see the symbol for "ohms".
