I'm trying to figure out a way I can monitor exhaust back pressure on the turbo kit I'm getting. Can you just weld a bund into the crossover and put a pressure gauge in directly or do you have to do something special?

thanks

Ahhh..

I remember talk about this... I think it was in the thread about

there are a couple comments in there but not much info on actually HOW to measure it.

Would a regular pressure gauge melt from the heat?

I wonder if they make something for this.....TTT I am interested too.

Use a regular fuel or oil pressure gauge, 50 psi or better and hook that up to a copper hardline that is 18+ inches long that is tapped into your head pipe leading into the turbo. An oil pressure gauge kit would be fine. Substitute the nylon line for an Autometer 3224 copper line kit. The copper of course could be used all the way to the gauge, but you don't want to flex it. Autometer also sells a pressure "memory" kit that is a one way bleedable valve that will hold the gauge at the highest pressure reading.

i used my boost gauge, just unhooked from the intake and hooked to an extra o2 sensor location

Great info guys, I have a few extra gauges lying around and will do with my turbo setup.

I did it before. I welded a female brake pipe fitting to the manifold, and then screwed in a male fitting with about 18" of brake pipe attached.
I wound this in a spiral to save space then attached a rubber hose to the end, and ran it to a large pressure guage.Think mine went to about 60psi, although dont recall what the actual EGBP was.

I'd guess 50psi would be a good scale for pre-turbo, and 0-10psi post turbo.

The idea behind the long copper tubing is simply to dissipate the heat so any rubber hose etc wont melt as easy.
I never had any problems with mine.

When finished, I removed the copper tubing and screwed in a brake bleed nipple to seal up the hole again.

on 17psi boost i made 25psi exhaust.

i took an extra o2 sensor plug and drilled/tapped it 1/8" npt and screwed in a barbed vacuum fitting.
