I needed to move my 9800 lb skid steer from Reno, NV up to Tahoe for my snow removal business. I borrowed my boss's 2009 Ford twin turbo 350 to see how it tows. My 96 always seems to get to hot even with my #10 plate 1/4 forward from full back when towing over 10k. I am very impressed with the Ford. Pulls the 12,000 load with EASE.

My trucks mods are in my signature. I am assuming a larger turbo alone would keep my EGT's much lower than what I see now? I never towed with a stock plate. Maybe a stock plate full forward with my 3K washer kit is the ticket for the heavier loads?

I am full aware of the injection pumps of the 24 valves. But the "on the fly" performance of the 24's really seems like the ticket for towing/performance.

I am assuming the 24 valves have a larger turbo than my stock 96?

 

I'm not sure how they compare, but a smaller turbo generally will perform better at high load low rpm than a larger turbo. Small is easy to spool and performs well under lower volumes, large tougher to spool but good for big power.

Pre-turbo exhaust leaks or boost leaks can be murder for egt's also...

The way I understand the design of the hx/hy35 turbos that went in the vp-44 24 valve trucks is that they were designed with a small exhaust fan for easy spooling, then a largish waste-gate for controlling back pressure under high rpm full load. Not so much the size, but the design.

When you say "hot" are you referring to engine temps or egts? If egt's pre-turbo or post turbo egts?

I don`t have a problem towing 10000 lbs with my 95 12 valve. i do see pre trubo temps of 1100 deg on my pryo towing on a long hill with my fiver, but don`t think that is to high a temp. I have some room to more the 10 plate full ahead and have not done it yet. I just get a little haze from my Col duals when I first push the throttle down. I hate to have to much black smoke. I think I would be just wasting fuel doing that. I`am very happy with my 12 valve. later Don

 

I would go straight from the 12V to the CR era, IF I were going to play with space shuttles.

Adjusting on the fly is nice, but the added complexity costs,and is much more likely to bite you on the road.

What EGTs are you seeing? The 24V Turbo is not much bigger, if at all ( I don't think it is at all )

 

spoken like a biased 12valver

 

With my 10 plate at 3/4 forward I can pull 10,000 lbs and easily get over 1350 on the EGT's and my engine temp will rise as well. Pre turbo temps. My boss's ford is slower than my Dodge. But tow's much better.

 

I have a 100 Plate full forward and have no issues towing 10-12,000lbs, don't see more than about 1200degrees maybe a little more on a good pull, engine temp never gets hot at all.

 

Yup, after Armageddon, 2 things will survive, Cockroaches and 12 Valves......

Suits me just fine.

 

aint that the truth 12v are sure hard to kill

 

Dont tell my buddy that, he has had more problems with his 12v than my 24v has had.

 

I wouldn't want a cockroach driving my truck....

 

Probably has a Rocket Scientist working on it.......... Kids these days, most have never even seen a set of points, much less learned how to set them with a Matchbook.........

Seriously, I have seen WAY too many "Mechanics" who need a 'Puter to tell them what to do.

 

HEY!~ Cockroaches need love too........ Besides, after I am gone, somebody has to keep her in shape.

 

Points? What are points? Whats a carburetor? You mean you can rebuild stuff, not just replace it? This is the sad face of our auto techs. I handed a young apprentice a fuel pump for an old small block chevy, he looked at me and said "what the heck is this, and what do I do with it!". Gone are the days of "fixing" things, it's now about changing parts.

 

The newer trucks, all of the big 3 are going to out-pull a mild 12 valve all day long. Feelings toward electronic engines aside, they have been designed, from a mechanical standpoint, to move air in and out more efficiently than our beloved 12v dinosaurs. Also, the cooling capacity of the newer trucks makes the older stuff look pathetic. HUGE radiators, HUGE intercoolers, HUGE tranny coolers, etc etc. It's a lot harder to heat soak a newer setup due to the sheer massiveness of the cooling systems. Pull a 12v hard at 2500rpm and coolant temps soar. Shift into a higher gear to bring the revs down and the EGT's soar. Now the intercooler is throwing real hot air at the radiator that is already heat soaked....it's a downward spiral
