Sorry about the poor quality of this video, it's just hard holding a camera while pulling 15k up 2 mile winding 9% grade. Towing our 5er home after spending as much time at the lake as we could at our seasonal rv site, this return trip was early October. I have pulled up this hill every year since 2002.
I hade this temporary pressure gauge set up to monitor boost and the digital egt gauge. I ran it real hard as you can see the rpm's in the orange for most of the time. I just kept it in 3rd, I think i was working the old girl pretty hard. I noticed towards the end of the clime the boost psi gauge dropped below 10 after staying around 20 the rest of the time. I didn't notice a drop in power but i may have blown out an up pipe gasket or something IDK.

 

Hit that dun!

 

Hard pull Rich! Could you hear an exhaust leak? Did the boost ever come back up? Crawl under and look for soot around the manifolds and up pipes. Also behind the turbo at the collector.

 

Is that a spirit level you're using as a tilt meter, on the column?

 

No couldn't really notice any difference in the noise, but ya know with my exhaust set up, hell I still can't hear anything

I did look for soot and noticed just a little near the top of one up pipe, I had new pipes put on when I did the clutch about four years ago. I'll have to look around the turbo. I don't think the boost came back where it was but I haven't pulled any more hills the 5er is parked till next year. The truck still seams to have good power though.

 

Ya, so we know which way to lean on the hard turns or curves

 

^^^^ Hey, I put one of those fancy dampered tilt meters on my tractor, and I actually DO lean to the high side going across the slopes (which is pretty-much our whole field...). Just never seen one on a 1-ton truck before; guess it makes sense with that kind of towing.

 

Pretty impressive considering mine gets hotter and runs slower with a lighter trailer.

 

Did you have that exhaust open on that pull?

 

Yes I did have the exhaust cut out open, I always pull the 5er with it open. I can and have pulled the boat (5k) with it closed, no problems there can hardly tell it's there.
I am a little concerned about my stock fuel, it hasn't gave me any problems yet. Correct me if i am wrong but isn't the fuel system mods to insure good pressure and fuel delivery, is there a real (noticeable) gain in power?

 

No gain in power but its better for keeping up with a lot of mods. The biggest reason I did mine originality was to get rid of those darn leaks!!

 

I have had this truck since 2006 and no fuel leaks, the valley is dry (oh no i should not have said that). do you think i'm pushing the rpm limits when i pulled that hill in the video, i could have went higher but i didn't feel comfortable going into the red. It was the first time i have been able to pull that hill with out the egt's trying to go over the limits, so keeping the revs up did help with that. Am i at risk of dammaging the engine doing that ? I stayed in 3rd gear knowing that if i tried 4th egts would go up and i would slow down and then would have to down shift anyway.

 

I have to say one thing.
I had a new pump.no leaks and an in cab gauge and a shimmed regulator with 70 psi at idle.under a hard pull my gauge would dip to 30 psi.I was not running that length of time you are. I could deffinetly feel a difference in my buttodyno when I did e-fuel . now I have gotten a t500 from Glenn and I have to say for stock Injectors and turbo Clifford is running plenty strong.....but what is next lol

 

I think from what you have above your about right for stage 1's next

 

You were pulling a 'little' bit higher rpm's then I usually do but the reason is my EGT's limit me. I've done some work on my turbo, a new hpop and I put my oil cooler back on so I'm hoping to get my EGT's down a little. After I pull the 5er again I will determine if I am going to put the water injection back on or not. Then after the water injection if I'm still not happy, I'm going to replace my IC with one of those fancy high priced ones to see if EGT's come down some more. If they don't, I give up! LOL
