Tech heads: need some answers....

I've been chatting at work to a bloke who's got a damn good mind!

I want to know if there is a sensor avaliable to show pressure in and electronic signal?

We want to put sensors before the turbo(s); between the turbo(s) and the intercooler and between the intercooler and the inlet manifold (or in manifold, which ever is easier)...

What, how etc etc?

Any thoughts/ideas etc?....

MAP sensor...

Pressure/Vaccumn switch, basically it won't give you a measurement, but you can make it trigger at certain pressures.

its a start, it also has links to some articles that might give you or your mate some ideas.

Permanently or temporarily??

[funkymonkey]

yeah or MAP sensors, but don't they measure air pressure in things like air filters?

[funkymonkey]

whoops, read this one also

Bass Junky, permanently... We wanna rig up a digital display that shows what the air goes into the turbo at; what it comes out of the turbo at (turbo effieciency or whatever you call it) then what it goes into the manifold at (ie what loss is caused through the pipes and intercooler etc....

Don't really wanna spend a fortune converting the car to MAP for that you know?....

just need 3 lil sensors that we can plumb into the pipes to send the pressure as a digital signal....

Does that help?

[funkymonkey]

how about this one then?

COuld the AFM be used as the initial sensor? or is the readings it gives different to what I want (as you can probably trell, I'm not as technically minded as my friend... lol!)

You dont need to convert the car to MAP based management...

A map sensor is a small, relatively cheap device that converts a pressure signal (ie from your intercooler plumbing) to an electrical signal...

Stock 33 boost guage is driven by a MAP sensor...

[DJ984]

Ah huh.... that could be what i'm after then?...

where can i get them? how much etc etc????

[DJ984]

funky, I had a look at that and it looks good too...

I was just picturing something cheap and simple that could be tapped into the pipes like the O2 sensors in the dump pipes.... any thing like that? is that what a MAP sensor would be like?

[funkymonkey]

that would be a sensor that uses a bourdon tube to measur the pressure then? I dunno.

[DJ984]

I have no idea what that is... LOL!

Permanently: You would then have to weld little lugs to the places you want the signal to be taken from and then attach a MAP sensor to each lug.

From there you would have to output that signal to some sort of display unit.

I can't really see this as being a cheap thing to do......

The alternative it to plumb up three seperate boost gauges....

I think Autometer now have digital readouts which have the outputs from two sensors displayed on the one guage. You can configure them to be whatever you want. (might not be autometer.... but it's someone.

BASS OUT

Yeah, the drilling/welding shouldn't be too expensive if we know a welder though should it...

We're going to design our own display unit, using the 3... so the 3 boost guages would be a waste of money....

So how much do you think it would be for the 3 MAP sensors?
