Boost Gauge Question

[blackdirtymax]

so is ther an advantage?

[maxxflip]

not sure, IMO id rather see how hard the turbo is working than how much boost the motor see's

[White05LLY]

When u remove the intake manifold to tap for boost is there a gasket that needs to be replaced or just use gasket maker

You re-use the metal ones.

i did as well tow master

mine is on the tube on top of the motor right off the turbo so i know what its putting out. the motor sees around 2-3lb less then what my gauge says.

im not worried about it blowing out then again i drilled the hole and welded a fitting on cus im cool like that!

I thought that's what the boost meter was for...to see what the turbo is putting out...if i'm wrong please correct me (be nice about it though!!! lol )

There is a pressure drop between the compressor and the intake due to the restriction caused by the intercooler and piping. You may see 36 psi at the compressor outlet, and 30 psi at the intake. 36 psi would be over working the charger. You dont even wanna know what drive pressures are at that psi.

plus just to add once you get over 35psi the air coming from the turbo gets so hot you actually loose efficiency...for the short amount of time your turbo is still intact

So whats the better spot pre or post intercooler ? and why?
