    Just double checking safe temps

    Alrighty, just installed my pyrometer over the weekend, an Autometer unit (wanted isspro, but this one'll work fine, and got a good deal on it) most of the time, temps stayed around 4-600, would peak to 8-900, and the time I tried to get them the highest, I was only able to peak to 1000, so i'm...

    Best 6.9 block

    Smoke can be anything from bad injectors, bad pump, improper timing, or air in fuel. On mine, I installed injectors and replaced the pump and return lines, and it still smoked. Turns out the timing was advanced a hair too much, and it fixed it just fine. Starts and runs great, and gets less...

    Pondering at work ?

    If you have an 87-91 series, I just took the plastic bulb cover off, and it's brighter than hell in the truck now.

    rubber fuel injector lines

    I've seen return lines replaced with these type of lines, but not main hard lines. And Hydraulic lines withstand incredible amounts of though, and they're multiple steel braided lines, it might actually be plausible.

    hypermax type s or pulse

    Haha and the propane was just in case you didn't make that 300 at the crank on the dyno, you could always give it a little snort and maybe tip the scales. :sly

    hypermax type s or pulse

    I posted quite a while back on this, for one thing, 6-800 is probly not gonna happen without a major teardown, and really really special parts. I figured a nice conservative goal would be 300, and by my guesses, with a good turbo, head studs, a custom ground cam to help the turbo, moose...

    Two Big Questions for you hardcore IDIers

    In my case, I just found a parts truck with 4.10 front and rear gears, and it was the easiest thing i've ever done. I went from a 1990 sterling 10.25/Dana 50 to a 1986 Dana 60/Dana 44HD, all I had to do was get new U bolts, unhook brakes, change yoke in rearend (wouldn't have to if same...

    Few pics of my truck

    I think I would sacrifice not getting powdercoated just for the sake that you can get Humvee tires cheap for 16.5. 37's!!

    Gas Burner Question

    I didn't know that you could squeeze 20 out of a 4.6 auto. the best i've ever seen anybody get around here is about 18, and nothing more.

    new bumpers!!

    You used only 14-16 guage? Isn't that a little weak? I went for 1/8 inch with 4 inch square by 1/8 inch tubing behind it. So about 1/4 inch total, in diamond treadplate. It passed the sledgehammer test and the tree test. :D;Sweet

    Aftermarket Tachometer Question

    Any factory tach sending unit from the IDI's will work, 83 6.9 all the way to 94 7.3 turbo

    Aftermarket Tachometer Question

    Your injector pump housing should have a port in the top near the oil fill where the factory Tach sender goes in, just unscrew it and put a factory tach sender in there.

    STACKS OR DUELS PIPES?

    if you've got a turbo, it doesn't matter. If you've got a n/a, I would just run duals out the back, there's no difference with stacks.

    Tear that old mechanic a new one, and have him pay for replacement heads

    First diesel rig, vibration question

    Sounds like a U-Joint to me. If it was engine, it would happen at all speeds at the same RPM, not just a certain speed.

    Twin Turbos, one off of each side, how to?

    What about a DT466 out of a tractor, I've seen plenty of those. But, they might have smaller housings and spool completely different.

    Twin Turbos, one off of each side, how to?

    I'm going to try to get ahold of my neigbors plasma and cut some flanges out, he said he'll help me with this project, and I'm going to see what happens. -Flame Thr

    Twin Turbos, one off of each side, how to?

    Yeah, I think a good set of smaller gas turbos would be great, but the objective here is to put it on a 21.5:1 compression IDI...so I think some small turbos would be adequate. But for the extreme side...I would probly go with twin t466 turbos off of a two ton. and then just run twin intake...

    IH parts/ interchangeability

    Now, heres another question, could you take the exhaust manifolds off of a 404/446 GAS series IH V8 engine and put them on a 6.9? I was gonna cut me some header flanges with the neighbor's new heavy duty plasma cutter. And had some 404 exhaust manifolds lyin around. Another thing, are bolt...

    Need your input, What Bumper,..POLL

    Well, you could always put the chrome on the Bronco...it would look reeeeal sharp on it, but it also looks good on the truck too.

    How much to swap gears?

    Oh, if you ever want to upgrade tires, don't switch to 3.55's, trust me on this one. I can't maintain interstate speed with my current tires, and they're only 33's. I get 18-20 on 55 mph highways, but it sucks down to about 12 on the interstate, and I can only keep it at 75 with a good...

    How much to swap gears?

    I'm just swapping out whole front and rear end, changing fluid, cutting U bolts, putting it under and bolting everything else up. I think it's easier, but I don't quite understand how to adjust the bearing shims and set preload and yada yada.

    How much to swap gears?

    4 wheel parts lists about 4-600 for parts, but it is an extensive labor process, could be up toward 1000 at a shop.

    Moosestang upgrade hit a wall

    Wait a minute, in the Ford Ranger world, they just take the stock axle housing and ream out the ball joint holes to fit a knuckle off of a Bronco's Dana 44. Why couldn't you just use the same, and that way you can keep with the ford parts? Here's the link...
