Boost Gauge

08-12-2001, 12:29 PM

Where is the best place(on the engine) to hook up the boost gauge. Someone told me to hook it up to the plastic vacuum t, all I get is a vacuum reading(no boost).

You should be reading boost from there. You did check it while the car was moving and under load...right? You won't see any boost reading unless the car is under a load.

Yeah, tested it. I thought the exact same thing, but that isn't it. The vacuum goes from 10 to 0 but never goes into the boost side of the gauge.

I may be way off, but I thought Boost only applied to Supercharged or Turbo engines, and that on an NA car your Vacuum would only go to 0 - but you would never have any Boost...I am sure someone who knows will answer!

You are not way off. In fact, you are exactly right. Problem is, Ricks puppy is supercharged.

Rick-
Man, I hate to say it, but unless you've got some trick new system, all sources of manifold vacuum will show any boost you have. Either your gauge is bad, or you're not generating any boost.

what type of blower do you have? if you have a powerdyne, your internal belt might be broken.

I don't think Rick would be caught dead with a Powerdyne. I believe he has a Vortec.

Thanks guys. I have a vortech a-trim. I got on the mustangworks chat room last night(you should check that out Chris) and was talking to some guys with blowers. Apparently I won't see boost until I'm over 3000rpms, I will check it again this morning on my way to work. I was thinking I'd see boost sooner. I will post wether I got it to work or not. It feels like the blower is working

I got it to 4000rpms this morning and it registered only 3psi, I guess its working. I didn't get on it real hard saturday. I thought I'd see boost much sooner than that. I wanted to push it harder this morning, around 6000rpm, but it just gets up in mph too fast now

(never thought I'd say that..heeh). I got to get this thing out somewhere where I can push it and see what kinda boost I have.

Right now I have the boost gauge sharing the line with the fmu, I'm thinking of putting the boost line on the intake itself. Maybe that would be more accurate? Anyhow, thanks for the replies!!

P.S. If you have an aod, I strongly recommend the lentech valve body and a non-lockup convertor. Gas mileage will suffer but man does this thing move!!

Glad to hear everything is working properly! But at 6000RPM I don't know that I would be looking over at the Boost Gauge anyway :-)

Rick, it doesn't matter if you jump in the deep end of the pool, or the shallow end, you're still gonna get wet. Vacuum (and boost) are the same at all vacuum ports that don't have an inline restrictor of some kind (ie: every vacuum hose on the late 70's carbed cars). It also doesn't matter how many items are plumbed into that line. You're fine where you're at. Don't believe me? Try it and see. : )

Take care

Hey man, thinking and wondering are two pretty killer instincts! They lead to learning! I wouldn't know half as much as I do if it wasn't for them!
