Wastegate question

[BSdiesel472]

Triple s472s and 250% overs. What should I do wastegate wise

 

[mike diesel]

What are the specs on the s472's?

I would think one big gate around the primary s472. Couldn't imagine needing a gate to go around the atmo s472's if they are setup correctly.

72/83 for the low pressures, not sure if I want a bigger turbine for the high pressure or not

 

[mike diesel]

Those are huge injectors. I would run an 87 turbine on all 3.

Single precision 46mm is all I have and typically all you ever need unless nitrous is involved

I also run a precision 46mm and it has no problem regulating boost.

 

[BSdiesel472]

Nitrous will be involved

Thats good to know. The current gate setup on white devil is a single 45mm around all the turbos, i was thinking that I would need two gates, one around the 472 and one around the 366's, but now I might just try gating around the 72.

Good info.

I run a 60mm around my 72. You can do anything you need with that. No need to complicate things more than necessary. Gates still need adjusting for the system that it is used in to get the benefit if one.

Sounds like an odd setup. One gate bypassing all 3 turbos?

I was told I would need to gate my low pressures. If I don't have to then I'm not going to but I want some experienced oppinions

Yeah, dont ask me man, this thing was obviously built by a serious professional.... :roflmao:

That is on the list.

 

[delong_1]

to be safe id run one 46 to bypass the high pressure and feed the atmo's and another to dump to the exhaust when nitrous is used. this is how i have done them on all the stuff running spray.

Triple 472s and nitrous should make for an exciting combo. Curious to see what comes out of this.

X2. I'm interested in this setup. Been thinking of running something similar in the future on mine.

I run a 44mm around the High psi S475, nothing for the low psi 475's. Last season I ran no gate, killed the GT 42/45 but never killed the 475 un gated. Up pipes last longer now that it's gated though

 

[hondarider552]

I killed an up pipe bellow even gated :rofl:

I dont know I'm kinda leaning more towards a slightly larger high pressure now I think. Been putting off buying the third 472 cause I can't make up my mind. Wanna stay s400 though I think
