could you use a oil pressure gauge as a drive pressure gauge

 

Thats what I used. It was just a cheap oil pressure gauge from AutoZone. I think any pressure gauge would work. You will just need to get the cooper line to run from the manifold.

Im lost what is a drive pressure gauge. What is drive pressure and how inportant is it. Thanks

 

Auto tranny pressure????

 

Drive pressure is the pressure that is built up in the exhaust manifold as the exhaust tries to push past the turbine wheel. There is a ratio of "drive:boost" that you want to shoot for. I don't know what the ratio is though.

Thanks I was trying to figure it out but got nowhere.

 

Should work fine, just make sure you use a couple of loops of copper tubing from the manifold before you hook up to any plastic or rubber line.

I happened to have an extra westach combo boost/pyro that I used for drive pressure and post turbo egt. 38lbs of boost and 38lbs of drive pressure.

 

So where would you measure this at? Near and before the turbo?

 

You can pull your egt probe and get a reading from the manifold.
