Dawes valve question

[DieselBalz]

Mine tricks the wastegate, by entering a leak in the line. (I am sure ya know that) but am curious as to why you are pointing it out? I didnt even want the gauge, but like I said they were outta stock.

dawes valve doesnt let ANY air thru, then POPS the wastegate open

a regulator lets air thru till a certain PSI, then closes off, so it cant build any more pressure.. this way lets the wastegate slowly open like the way it works factory. the wastegate starts opening before desired boost pressure is achieved. thats the cool thing about the boost controller, it holds the wastegate CLOSED until it reaches its opening pressure, then the controller POPS the WG open.. the way you have it now, under low boost (below your wastegate setting) your waste gate will be opening slightly, and making your turbo take longer to spool.. we use dawes valver (boost controllers) for a reason.

a boost controller would work better, and let your turbo spool quicker

your air line regulator might work ok, but it doesnt function the same as a boost controller, and i think that having the controller keep the waste gate closed till XX psi is one of the big advantages of it..

(the air regulator kinda works backwards of how a dawes valve works)

thats the reason i brought it up..

Ahh I see. Thanks for the explanation.

 It builds boost continuously, but I dont feel it hit full spool untill about 3700 RPM and than it goes from 13psi to 20 psi, kinda like how a Saab 900s felt when the spool come on, but more muted of course. So if I switch to the Dawes, youre saying the boost will come on like mentioned above, but lower in the rpm range, taking more advantage of the fueling available in that range as well I imagine, for a little more punch?

the dawes valve holds the waste gate completely closed until the set boost pressure is reached, then it POPS it open.

without the dawes valve, the waste gate will start opening at say, oh, 4 or 5 psi.. the turbo feels sluggish because the waste gate is partially opening before it could..
