So I've had my compounds up and running for a little while now and I'm fairly happy with the setup but some changes need to be made. I currently run a s369 / 88mm gt55 combo with 400/200s and I feel that the s369 is just a little lazy to spool, once it's lit it pulls incredibly hard but down low...

So I've put some miles on the new setup and I'm comfortable saying the gate was an issue. I still haven't re-geared the rear end but even with the 1.10 housing on the 369 it's spooling about 200rpm sooner than it was originally. Ebp is a little higher than I would like to see but at 10lbs boost...

I got the mount mocked up today, was hoping to have it finished but unfortunately I'm out of argon so I'll have to wait until tomorrow to burn it in.

The 369 is back together, Reed @ work turbo sent me over an original borg warner fmw for it. As of now the truck still isn't back together, I'm changing up a few things while it's apart starting with the t4 mount. I like the idp mount that was in it but I feel like there's some improvements that...

It is

It's always been a fun truck to drive, even when it just had a set of 180/100 and a single 369. I'm pretty impressed though because even with the issues it's having its still incredibly powerful! I can only imagine how powerful it'll be when it's running right

The gate is a 45mm so like 1.77". Also what you're saying about the surface area of the gate makes a lot of sense. As far as how much boost it makes in park revving to 3k I have no idea, I can find out but it's going to be several days before it's all back together again. Reed shipped out that...

The exhaust side and bearings are fine, nothing wrong there thank goodness. I do have a theory though and correct me if I'm wrong but I'm only pulling ebp from the passenger bank and it makes ebp sooner than it makes boost so if I'm seeing 10psi ebp (on the one bank) then the gate is seeing a...

Reed from work turbo is shipping me out a new compressor wheel tomorrow so that's handled. Now for the second issue, the gate is opening early and im not really sure why. Like I said it had 26lbs of spring in it and is fed full boost to the dome so theoretically it shouldn't open at all.

I checked the 55, it's fine. Also pulled the turbine housing and all is good on the hot side, the compressor cover has a few spots on it but they're all around the surge ring and look to be just cosmetic. The area where the compressor rides amazing looks untouched, the bearings are fine as well...

Well I dug a little deeper and found a pretty serious issue, something has made its way into the compressor wheel of the 369 so I'm just gonna assume that's part of my problem

Okay so I pulled the intermediate pipe on the hot side and the interstage pipe on the cold side and ran it as a single s369. Same issue, no boost being built until about 2500 rpm. So atleast I've narrowed it down a little. May try throwing on that 1.10ar housing I have and see if anything changes

The 55 has a 111/100 turbine and a 1.23 housing, the compressor is a cast 88/123. I'm thinking that tomorrow I may pull the intermediate pipe and charge pipe off the atmos and see how the 369 spools as a single. That should tell me if the issue is with the 369 or elsewhere.

I do agree that the hp charger should be making more boost, but I'm positive the gate isn't the issue. It has 26lbs of spring pressure in it and is fed 100% manifold pressure to the dome so it's effectively pinned shut and non functional. Also I vented it to atmosphere because I was concerned...

I've searched for leaks everywhere! That was my initial though but there are none to be found. I haven't yet tried a bigger housing on the s369, I have a 1.10ar housing for it but was reluctant to swap it over until I figure out what the root cause was for the lagginess. I didn't want to make an...
