    Towing heavy at 20MPH

    Well said, fellow grain hauler, well said!

    banks wastegated compressor outlet temps

    Good work and info! Try it again at higher ambient temps. Generally speaking, IAT will rise the same amount as ambient, so at 100F, IAT should be at around 266F. It would also be useful to see the Pyro readings at the same point. In order for this to be an apples to apples test, write down...

    Towing heavy at 20MPH

    I'll try to get this back on topic. Insofar as the original topic goes, i.e. "towing heavy at 20 mph" all this GV brouhaha is moot. The truck did fine without it. I tow as much or more as the OP twice a year and have every year since 2003. Once towed as much as 31 tons with my IDI. All...

    egt temperature question

    Google "filter minder" they have many different styles, including a remote one for the dash. You want one that has a range of 10 inches of water on the low side and 25 on the high (up to 30 is OK too). For maximum power, you want to clean/change filters at 20 inches, but 25 is the normal time...

    egt temperature question

    Good post Warden. I did a little reading on the NA thing too after this post and it appears high EGTs are the norm for NA trucks. In some of the material I have from the '90s, Jim Bensen, the guy that invented the ATS system, said a turbo kit actually made the engine MORE reliable when it had...

    86 f250 6.9 rebuild/refresh advice and questions

    While I agree on following up with another retorque, the 80 lbs-ft is there for a reason. Nobody has made a sufficiently technical explanation about the plusses and minuses of going tighter. It's just been "tighter is better." Maybe. Maybe not. Doing it, and going against what the manufacturer...

    Chipped precups

    The 7.3L pre cups are different but I don't know exactly what effect it has on anything. I did fool around with different pre cups on the 6.2L GM, which also use the Ricardo Comet V combustion chamber. There were a few different types on the GM, including one used only on the turbocharged...

    egt temperature question

    Both. Melted pistons are melted pistons. While the upper numbers I listed are more or less generic, in terms of the structural limits of the engine, how they are achieved would be different. I imagine you'd have to be radically overfueled and smoking like a locomotive in an NA engine to sustain...

    egt temperature question

    My advice is as follows: Maximum Short Term: 1100F (short term means 5 minutes or less) Maximum Sustained: 900F (a long, hard pull up the mountain) Your numbers seem typical and nominal to me.

    Debris found on oil change

    Good point! A valve wobbling in a bad guide can break a seal too. I forgot to relate a 6.2L diesel broken spring story that Typ4's post reminds me of. The spring was broken on the second coil but the valve had not dropped. What was left of the spring wasn't able to fully close the valve... SO...

    Is my Blocks Life Over?

    FYI, go back and look at my blown gasket and fretted head pics above, now that IDIoit has clued me in on a Glitch the Burners Forum has when attaching images when replying.

    Debris found on oil change

    It's a valve stem umbrella seal, not to steal Gary's thunder for first calling it. They are plastic and get brittle with age, break and can work their way down into the pan, where they stay because the chunks are too big for the pickup screen. No biggie really, in and of itself, though they...

    banks kit up and running

    High altitude most definitely is the cause of more smoke. When I lived in Grand Junction, I kept my pump cranked back about a flat from the sea level setting. I would still roll coal over the passes on 70 but at home, I liked the relative lack of smoke.

    DT 360, DT 466

    The DT466 is the better engine. Honestly, and with all due respect, if you have to ask which is better and how to put it in, it's probably beyond your current level of skill.

    Building a 6.9 to kill

    That's because a stock '96 PSD was rated at 210hp and 425 torque, flywheel, a little less than your modified ID was putting out (est. 220-250 @ 500 lbs-ft, give or take). Plus, they gotta have the same axle ratios to make it a fair comparison. Still, I experienced the same thing; a buddy in...

    Is my Blocks Life Over?

    Oh, I missed something then. I thought is WAS out of the truck and apart. If the bores are good, that doesn't preclude just honing them, decking the block and doing everything I outlined. Overall, I think it's a fairly safe bet to put studs on it with new gaskets and run it. I looked at my...

    Building a 6.9 to kill

    Here I go whizzing on the parade again! ( : < ( Frankly, I think you are about to waste a lot of money. It's your money to waste and I don't deny the road you are contemplating is an interesting engineering puzzle but the fact that you are asking for internet advice tells me you probably...

    egt temps

    I think those temps are a little hot but my experience with NA Ford IDIs is minimal (put the turbo on my '86 in '87 when it had 7K miles) but that would be hot for my turbo 6.9L. At 60 mph, mile is about 500 and not much more at my top speed (4.10s) of 70 mph (3000 rpm). But again, My only...

    Is my Blocks Life Over?

    I agree. Steady state RPMs have little to do with it. My truck has 4.10s and 3000 rpms doesn't come until a bit over 70 mph with 33s and 65 with the stock 31.5". Anyway, that damage comes from the heads lifting... and that can come with a hard worked NA engine too. Since we know the engine has...

    Is my Blocks Life Over?

    Well, I guess everyone can see why some of us harp about studs. Not twisting the knife on you, Sailor, it a teachable moment. Anyway.... Same thing happened to mine. Comes from lots of combustion leakage and head lifting from stretched head bolts. The block deck can be surfaced but you have...

    The Banks Vs Banks Thread||T04b vs Te06h|| ...not another turbo thread

    You are overstating. It's "higher" not "high." At the same fuel setting and the same load, the wastegated turbo will produce higher EGTs. That's mostly at the higher rpms or heavy loads. Again, that is an issue mostly for those who tow heavy and for long periods. Try towing over the Rockies at...

    The Banks Vs Banks Thread||T04b vs Te06h|| ...not another turbo thread

    You're mixing gassers and diesels. Two different animals. One is a throttled engine, the other is not. But again, it's the combustion chamber design on the IDI that limits practical boost. Your "boost=power" comment applies mostly to DI diesels and gassers. You can boost the IDI as high as...

    **UPDATE** FP DIESEL GASKET SET

    My new 2009 era FelPro 6.9L gasket was 0.074" on the body (the important measurement), 0.089" on the fire ring. The '90s era FelPro gasket I removed measured 0.064" on the body, which would be close to compressed thickness. They do expand a little when removed.

    The Banks Vs Banks Thread||T04b vs Te06h|| ...not another turbo thread

    In looking at dyno charts and dyno test data collected over the years, the wastegated vs non-wastegated kits develop essentially the same peak boost and power. Peak torque is nearly the same number but with the wastegated, it comes in a little sooner. The only potential downside is higher EGTs...
