Towing Twins & Injectors

[tampabayBill]

Looking for input here guys. My main interest is quick daily driver and heavy ( 13k lbs ) towing. Have towed from Tampa to Beaumont with 13.5 mpg and egt's never reaching 1100 and tranny at 180. But as y'all know its a pretty flat tow. When wife retires plan nation wide trips so.... more power cooler air in the plans. Thinking about HTB3 for primary and my 14x60 as secondary. How about some ideas about injectors, I'm not looking to race or sled pull just good reliable over the road power. Lastly anyone make a kit to put it together?? Thanks guys hopeing for a good responce.

Thanks for info on the PDR Twins. Looks nice if a bit pricey. Was hopeing someone on this forum was making a kit to do this ie. hot & cold pipes, braces, drain lines etc. How about some input on injectors for my setup with twins. Don't want to smoke everyone out, but am looking for 400+hp. Just don't want to be passed by newer stuff on a grade.

I don't know that our cooling system will allow towing heavy and 400+ rwhp. I also think it will be hard not to smoke at that power level while towing heavy. You'd definitely have to pay close attention to your right foot at all times. Not to mention the stress on the rest of the drivetrain.

No part of these trucks will allow you to tow at 400 horses. In my mind anything over 300 and towing is pretty dam hard.

Mr Richie why's that? You've peaked my interest in this. Radiator to small, not enough I/C?

Its just to much power for the frame, axles ( dana 70 anyway ) and such. I am sure someone could build a 400 hp towing engine, but it would have to be someone way higher up the pay scale then me. Keeping it cool would not be easy. Not only egt's but heat soak to the cooling circuit.

Sounds like 400 hp hopes just not real for towing trailer I've got, or maybe any big enough to be a comfortable full time RV'er, I picked it up because it was a great deal but have been planning to replace it with something about 26 - 28 ft range at approx.8k gvw, more in line with trucks capabilities. I won't be doing this traveling for 2 yrs, so have time & funds to up grade. So still looking for input on injectors on my setup with porposed twins. Last dynoed at 268hp & 636 lb/ft at the wheels. That was before the port job and the propane inj.

Towing even just 10k with mine out here in the Oregon mountains is a workout for the cooling system. My egts get out of hand with the stock turbo so I can't just mash 'er n go, I have to stay down around 26-28 psi boost to keep egts n check, but after about 4 miles of 6% grade my water is about 225 and still climbing. Lower egts might help some but I don't think it'd make a huge difference. I recently swapped the auto for a getrag and it seems to tow a lot better now but I haven't been over the mountains yet. Like Richie said though, the rest of the truck isn't really up for that kinda work and power. That doesn't mean you can't build 400 HP and not work it though, besides if you have 400 HP and towing 10k lbs you won't have to stay in it hard for very long anyway. You'll be going so fast you'll either slide through a curve or rearend someone ha. 95% of the time you're only gonna be using 150 of the HP you have.
