BW S369?

[Six_Sloww]

Wow, I'd be at 1100 cruising at 80.

Egt's will vary greatly truck to truck, turbo is only part of the equation.

I'm going to guess you have big tires and tall gears

This truck is on 35's and a leveling kit so not much taller than stock.

If it is you would hardly notice the difference. It has to spin a larger wheel; sure it has better dynamics and an unclipped turbine, if anything it probably spools just like (maybe slightly better than) a 366 which is impressive with a 3mm larger wheel.

Also depends on what engine you two are referring to?

6.4's are the engine I was referring to

My Billet S366 drives excellent on 6.4 with stock fuel, I bet the S369 would drive good and have more power, I heard they spool up real quick.

I imagine with the right tuning (and mine being a 6 speed) that the 369 would make good power, I just don't want it to be too laggy from a dead stop, plus towing 5-6000 lbs a couple times a month has me a little worried too

Drives really good, I'd say this S369 spools better than my old Bullseye S366 I had. I think the unclipped turbine wheel helps spool up for daily driving. Cruising at 80 mph the EGT's were at 768 heading to NW Texas.

This is good news!!!

Thanks a lot for the replies everyone

35s and 3.73s. Shouldn't even be a problem

No, it shouldn't. But I wouldn't assume the 369 would drop your cruising egt 300*, you could have problems elsewhere.

Just need to get the injectors swapped out and toss this beauty on! Pretty excited!

Everyone keeps telling me that, but no one can give me a solution. Haha I can't find an issue.

Egt probe bad?

She's brand new. Appears to read right at idle and what not.

Boost / Exhaust leak somewhere ?

I have yet to make a boost leak detector, something I can pressurize the system to ~20psi and spray everything down. No exhaust leaks, brand new BD manifolds and uppipes.

 

[SEABEE08FX4]

Gotcha, I'd make a detector for sure. Always a handy thing to have.

What would you use to make it? And would you put it in the intake of the turbo, or unbolt it from the turbo and out it on that pipe. I'd like to go from the turbo so its the complete system but don't know if I'm gonna hurt something.

 

[Six_Sloww]

I'm not sure if the seals on the turbo would like the static pressure, usually that turbo is moving the air, even if it's being forced in but I could be completely wrong.

I'd use a pvc pipe the size of the ID on the hotside boot, clamp it on with a cap on the other end that has a barb so you can put a hose with a T to a pressure gauge and a schrader valve.

Lol good ol Google knew what I was thinking.

PVC cap matching the size of the boot on the turbo compressor inlet, then tap it for a gauge and a air chuck. You shouldn't need much, 20-25 psi should do. You just want to listen for leaks and or see if it bleeds down quickly.

There are no real seals in a turbo, just a metal seal ring. Going through the intake is fine.

 

[SEABEE08FX4]

Adding a bleed valve would be a good idea too, that way you done have to take it off under pressure if its holding.

I tow with my truck being a (auto) it's a little different than a ZF but, it lights real quick from a stop. compared to a compound truck initial spool up is "alittle" slower from a stop light but it is not as bad as everyone thinks.

I run GH tunes on my newest reversion I noticed sitting at idle the truck is making 0.1 - 0.2 psi of boost with my older tunes it would sit at -0.3- -0.5 at idle.

cruising empty at 60 (500-700) egts with 3-5 psi of boost.

my truck has 3.55's and 35's with 3 inch lift.

Thanks a lot for the info. Single has been on my list for a while but deciding on the turbo size has been a headache.
