I just found the 1.0 quick spool housing from beans diesel performance for $155. The banks is spendy!!!!

 

If you tow alot your EGT's may be hard to control with the 1.0 as it raises EGT's

 

Yeah Check I plan on getting an intercooler in the near future but that spider is a tough one to find!! Do u know if the piping from an early 99 ( from the intercooler to the spider) fits our rigs? I think I am about to go on a mod binge again. Watch out pocket book. Lol. My dual 4" stack parts should be here this weekend!!!
I have a tough time building my boost up to 15psi. It reaches that at 2500 rpms and WOT. That should mean definately boost leak. I got under the rig and took a close look at the uppipes and no soot anywhere. Hopefully I can get my leak detector on it this weekend. And bump my fuel psi up to 70 instead of 65psi and new fuel filters. I got the F-6 chip sitting in the shopping cart waiting to pull the trigger!!lol

 

Btw I dont tow much now but who knows what the future will bring. When I finally get moved back to WA I am loading the beast up so I want to be dialed in for that for sure!!!

 

I think you have leaks then! Put the compressor on it again and spray some soapy water on the plenums, intake spider and hoses. The bubbles will show you where your leaks are. Also, you may have to turn the engine over slightly by hand to get it to seal up since it is possible for the exhaust and intake valves to be open simultaneously in the same cylinder. It won't be a lot, but they can be open enough to foil your attempts at this test.

Personally, I would get your boost leaks sealed up first, then worry about a quick spool housing after the fact if you still feel it is necessary. You may change your mind once you get that tuner on there and your boost leaks all sealed up. Especially if you ever plan to go with bigger injectors, the stock turbo will spool QUICK with stage 1s.

 

Yeah Check thanks for the insight. Do u think my baby compressor is enough?

 

I think it should be since it really doesn't have to provide a lot of flow unless you have some massive leak somewhere. My guess it that one of the cylinders had both valves open and that is why you couldn't make any pressure. You're using a regulator to regulate the pressure down right? Don't want you putting 125 PSI in your intake, lol. I have heard tell that the home made tester can really fly if it lets loose.... 30 PSI is plenty. If everything is closed inside the engine (meaning the valves) you should have more than enough air from a little pancake compressor to do the job, IMO.

 

When I was putting air to it I didn't hear air leaking so I assume the valves were open. So I should set my compressor to 30psi and let it pump away.
I plan on sticking with my Cali splitshots. If that boost leak is I at the prelims I sure hope I don't have to remove the turbo but if I do then the 1.0 housing is getting installed. Hopefully the honey do list ain't too big this weekend!!lol

 

Yeah if the valves were open the air was just going out the tail pipe. With your Cali split shots you should be able to spool that stock turbo up quite nicely once everything is sealed up good and tight.

 

No wonder I always felt like the rig was a little under the weather. Not boosting right could result in higher egts correct? My boost slowly rises and maxes out @ 15psi @ 25-2800 rpms. Man I just want this rig running the way she was mean to be. Thanks for all the input and will post up when I find this leak that has been haunting me.

 

Yes, boost leaks will let your EGT's get up there. You're not pushing the air through the engine that it should be getting, so your EGT's are higher and you are putting less power to the ground with the same amount of fuel because you're not getting an optimal burn. Get everything sealed up nice and tight and see how you like it then!

 

Perfect thanks again!

 

That actually sounds pretty common for a stock truck IMO.

I have three trucks.
96' F250 5spd (PHP chip) MBRP
97' F350 A/T (completely stock)
01' Excursion (DP Tuner)

Both my 5spd and A/T OBS trucks would slowly build boost in stock tunes. My 5spd would boost much faster with the tuner in a tuned mode. Still haven't added a tuner to my 97' A/T yet, but plan to soon. In stock mode both will max around 17-19psi @ roughly 5000ft in elevation here in Colorado. In 100hp mode, the 5spd hits 24-25psi at WOT.

My 7.3L Excursion with a DP-tuner will hit 17psi about 10ft off the line though and build from there FAST. In stock mode it would take forever to boost much like any other stock rig. It is a huge turd in stock mode. I hit 26-27psi @ WOT in pretty much any mode with the tuner on.

My 5spd would hit a max of 1250* under heavy load in tow modes. That includes towing my buggy and weight in the truck(7K total) around the mountains. Haven't towed much with either of the other two trucks except for a pop-up trailer. I just liked towing with the 5spd more as I rarely ever have to shift out of 5th except for the big grades of 6%. I can easily pull both major passes over I70 at 65mph in 4th. Well, unless some trucker going 32mph needs to pass the other trucker going 31mph.

 

Well now u got me wondering??? Pullin a short hill 45mph @2500 rpms and she was maxed out. With maybe 1k pounds on the bed. I know it's got more than that. With WOT that boost should shoot up once it starts building but it builds really slow and when it is time to shift I finally hit max boost. Hmm weird. I am goin to check for leaks this weekend and hopefully get my dual stacks on.

 

That has been pretty typical of every 7.3L A/T truck I have ever driven. They are slugs. They just don't boost quickly. Add a DP-Tuner and it will flat out FLY! Quicker, firmer shifts, fast torque converter lockup, way better throttle response, and obviously way more power/torque.

I bet when you first shift, before TC lock up the turbo is spooled up more and that is when you see max boost, right?

My 97' is a slug unless I am at 3/4 or more throttle. My Excursion was the same(Still is in stock mode), and my 5spd was too. After adding a tuner in both the 96' and 01' at 1/4 throttle you are hauling ***. However, its like driving a slow 4cyl when I get in the 97' in comparison. Its literally a night and day difference.

FWIW, once you install a tuner, you will soon wonder how you ever drove it without one.
