boost gauge

[Bigbunny2007]

Looking at fitting a boost gauge on the terrano, is it ok to tap into the intercooler just above inlet from the turbo? Im going to tee into the pipe off the actuator to fit the boost controller. Am i right her or making it all up! Also what boost can i run safely?

Yep that's fine, however, you could tap into the hole left in the throttle body after removing the throttle flap and spindle ?

I fitted a boost gauge to mine, made a you tube vid, not that good tho as access wasn't good for camera

Right ok, ill have another look then, does it improve things with the throttle flap out?

You may want to consider fitting after the IC, as the pressure seen here will vary with IC efficiency. Additionally, this point is the actual boost at inlet manifold and not turbo output....

Negligible, but one less thing to fk up

 

[Bigbunny2007]

so closer to the turbo output is more accurate? what boost can i run safely?

Makes perfect sense to me, Rick

Closer to the inlet manifold is more meaningful with regard to boost pressure seen by the engine.

Thanks for the replies ill fit it this week if working does not get in the way!!!

Update...

So the boost gauge is fitted, tapped into the IC on the inlet manifold side. On my run home it read 14 psi which i think is correct as standard :thumbs

Good stuff, that bit is all working good then:thumb2
You asked "what boost can i run safely?",.. well there is not much point in pushing too much more air in there without fuel to match!
So, if you are going for max, your next gauge should be an exhaust temperature gauge.
Rather than me babble on about it, here's a decent write up on why diesel EGT's should be paid close attention to:

Thanks for the reply.. i now want one :naughty
I was going to ask about turning up the fuel but i need to see which pump i have first! I was thinking about upgrading the turbo, is there an upgrade thats popular? or is the turbo thats on enough?

I've been down this route and you cant turn up the pump as it's ECU controlled
So to benefit from increased boost you'll need to chip the ECU with a powerbox of sorts. that'll fool the ecu into delivering more fuel erly on , and so getting you more acceleration. Top end though wont change , but you'll get there quicker :sly
The best way to get oodles of extra power and use boost is , power chip AND an LPG injection system.
Then you'll have a leary tool and also need a 3.0 l clutch :doh
Enjoy
