Is the 6.9 really this gutless?

[Dubshot]

I have a 6.9 with a banks sidewinder turbo and a c6 with a low stall converter.. I also have a heavy @$$ trailer and I couldnt get it to stay above 40 to 45 going up decent hills is this normal?? I would think a 454 or 460 would haul up the same hill I could in a 99 half ton silverado with a vehicle on it.. This is my first diesel and so far im disappointed..

A 454 or a 460 would... and get you about 5mpg doin it. Is your fuel turned up with the turbo and do you have gauges?

 

[Dubshot]

I am a serious noob at diesels with no gauges.. I dont know ANYTHING about them..

 

[milightfo]

it depends on how heavy the trailer is and what grade the hill is,even a new powerchoke would have a problem in these circumstances

also front breaks were locking up and rears didnt even seem to work.. I have not checked them i will tomorrow.. I couldnt give you the hill grade the trailer is solid steel but my chevy 5.3 or 4.8 didnt have these problems up the same hill..

something sounds wrong somewhere,i would change the fuel filter to start,maybe turn up the pump a bit but make sure you get a pyrometer so you dont have a meltdown

 

[towcat]

sounds like there is much cleanup and prep you need to do with the truck before you throw a load onto it.
post a pic of the stuff you got going on under the hood.
even the IDI's got advancements in aftermarket turbo tech.


one more thing....
I'm going to throw the B.S. flag on saying the chev 4.8 and 5.3 has more guts towing a load. they feel torquey when running empty, but they do die off when under a load.

im going to go ahead and call bs on yer bs call.. Im not a liar i just ran the same trip last week.. So that comments out.. Ill try and get some pics but its dark.. It had more guts up the hill with and without a load trust me thats why i think somethings wrong.. where do I turn up my fuel? Where does a pyrometer plug in? ill change the gigantic fuel filter

At my altitude, 4500ft and up, the 454 was unbearably slow, whereas the 6.9 with the Banks has no issues and does it without sucking the fuel.

you may want to read some of the threads on here how to do some of this,but to breifly answer is turn up fuel in the injection pump,prometer goes into your exhaust manifold,and be careful not to get air into your injector lines when u change your fuel filter,this sight will tell you anything you want to know if u search it.good luck

You made sure your kickdown is intact and hooked up right?

 

[Dubshot]

Ill do a little reading and change the filter tomorrow find a pyrometer just need to know where to plug in a boost gauge on the banks sidewinder turbo and a pyrometer and where to bump the fuel up.. You guys are awsome keep the ideas, thoughts, and comments coming..

 

[Dubshot]

kickdown seems to be in tact it drops gears well.. just seems like i got 3 speeds in my c6 and need 5 lol.. How do I prevent getting air into the injection lines?
