Nice work wreck, how is that tip? I still need to get one on mine but they are much too pricey, lol. I'm tryin to find one for under $75, lol.

 

sounds like i found the right thread...i have a 6.9 liter from a 84 e350 van...its going in my 79 supercab..with a zf5 spd...have a couple questions...
1-in stock form without bumping the turbo what kinda power does this setup result in?????
2- is 8-10 psi fesible with a stock pump injector if there turned up????
3-how reliable is this setup once tuned?????
4-will a intercooler be a benifit on the above setup or a waste of time????
thanks guys FTE rocks...

 

1. Not sure what you mean by bumping the turbo??
2. My turbo hits 10psi easily with the pump turned up 1 flat.
3. Very reliable
4. A intercooler will benefit you power in the higher rmp range, you will get some turbo lag after adding a intercooler but nothing to worry about. The power you will get in the higher rmp curve will make it well worth it.

 

sorry i guess i ment without adjusting the waste gate...and by turbo lag you mean it takes an extra second or two to get rolling hot?????does intercooler size matter alot?????

 

The PO of my turbo must have messed with the wastegate or Pensecola sent me a turbo pump (unlikely since it don't have the torque screw), I hit 11psi on a freeway blast during lunch today. I'm still wondering about more fuel though, I haven't seen much over 600 for EGT. The smoke is a little haze when I stomp on it but it clears up pretty quick once I'm past 7 or 8 psi. The only worry I have is not knowing what the wastegate is set for. I'm afraid more fuel's gonna push me into the danger zone, wherever that is. I've heard some say up to 15 but Ats says don't go over 8.

 

ATS is wrong on alot of things from my experience. Setting the wastegate at 10psi is normal and you won't get any more power above 10psi anyway unless you have a intercooler.

 

so build my custom manifolds, mount my turbo, install vacuam line, run oil lines, run intake/exhaust tubing, turn it up to 10psi, turn up pump some, run intercooler, adjust blow off valve, and see if it can boil the duals off the truck....that about right???????? any recommendations on locating a dual mass flywheel and what it comes off???? and what type of clutch for my five speed...p.s. what kinda fuel mileage you get empty and pulling say 10k??/

 

I haven't calculated yet so sorry. I recently installed a rebuilt pump, bigger exhaust, and back in time a little more a turbo and BB injectors. I just haven't gotten to calculating yet, lol. I wouldn't be surprised if I was in the the high teens, maybe 20mpg - just speculation though.

 

you should make yourself a signature telling every one what you've got exactly. Empty mileage I got 16 before the turbo went in using summer fuel. I think you may want to consider geting a single mass flywheel if your gonna be workin it hard. I've heard the stock DMF can cause problems. Read up. Use the search function. Explore the vast chasm of knowledge the self learned experts of the IDI forum have compiled for us! I've tapped it many times!

 

I disagree about what you're saying. ATS isn't wrong, they are cautious. Much like Ford is "wrong" on the tow ratings for manual tranny trucks vs automatics. If don't remember if this is true for all, or the years, but in most cases the manual tranny's are rated for significantly less weight than automatics are, even though the manual tranny can take the weight just as well, or even better without exploding.
Why is that way? Because many consumers are idiots and don't know how to properly use a clutch when towing. Ford didn't want to deal with warranty issues on burnt out clutches so they downplay the weight rating.

ATS doesn't want the average idiot that wanted more power from the turbo to turn things up, melt the pistons, and blame ATS. Note the average idiot won't know what a pyrometer is for, nor how to watch them. The system is designed for the average idiot, hence the instructions not to play with the wastegate, and the way they tell you to turn up the fuel. If done like ATS says, there should be no way the average idiot will blow up the engine. Kinda like how Ford changed from a "real" oil pressure gauge to just an idiot light by changing the sender and adding a resistor to fool the gauge.

After saying that, if you are careful, yes you can turn things up a bit and not blow up the engine. You just have to remember who the ATS/stock system was designed and built for. Just look what Dave Sponaugle has done with his truck. The loads he is hauling, with 3.55 gearing to boot, is way more then Ford says is possible with an F250. But Dave is not an idiot, and knows what he is doing.

therifleman556,
What problems have you heard about the DMF? That is a hot topic by itself! I'm very happy with the DMF, and again, it was put there and on many other diesel engines these days by engineers that know what the hell they are doing. Most people want to replace it because its damn expensive, and most people say they can't be resurfaced. Makes for pricey clutch jobs.

That said, there is an internal clutch on the DMF that is designed to slip if it is overtorqued. That is supposed to prevent damage to the transmission or driveline. The reality seems to be that once it slips, it will start to slip and wear out, which means you now have to replace an expensive DMF instead of possibly a tranny rebuild... The internal clutch on my DMF started slipping. I really don't know why, I'm assuming it was abused by a previous owner, as I really didn't push it. End effect, it was fine at speed and on flat ground, but would slip going up hill, the clutch disc itself wasn't the issue, it was the internal DMF one.

I opted to replace my DMF and found one on clearance luckily. Before install, I took it apart and JB-welded the internal clutch parts together. So far no problem!

 

When ATS says that pyrometers are useless and you can't trust because of the many places you could put them giving you varied results - they are wrong. I agree with you on the other things, stupid people who have no common sense annoy the mess out of me. And companies do have to give conservative numbers for liability, but when I heard ATS doesn't recommend using pyrometers, it makes me wonder.

 

whats a signature????
if you jb welded the inner clutch together doesn't that defiete its purpose....and make it basicly a standard flywheel????

 

The thing right below every one of my posts describing what year truck I have, etc. This way when you have a problem, we won't have to ask you what year, tranny, 4x4 or what not.

 

go to "user Cp" and click "edit signature".

 

On further reflection, I think the DMF comment came from sources citing it as a weak link in manual trany PSDs running higher power levels. So an IDI likely wouldn't need to worry. I apologize for any confusion on anyones part (mine especially).
