not directly .. but ( I like this But .. )

Lower EGT means more room for more fuel .. more fuel in a turbo diesel engine means more powa ..

So if you run a big front mounted intercooler or a top with a fan intercooler, you are always getting lower intake temps .. that drive you to lower EGT that drive again in to more room for fuel ..

Actually if you just add more " boost " ( and know boost it's relative between fuel available and engine load ) there is nothing more than boost ..

But .. ( again this But ! :D )

with more fuel ( that it's the main reason to run a turbo and anyind of intake temp cooler ) you are producing instant more powa ..

this is completely true!

also, if you don't have low enough air intake temps this could eventually cause detonation... :bang:

good luck!


you could really go all out and get that kit that sprays water on your intercooler and significantly lowers your EGT, resulting in (as tapage says) MORE POWA!!
 
water and methanol :meh:

The Cummins guys in Memphis are a good group of people. I hung out with a guy from there last month. He was talking about some new products that sounded sweet.

While we're on the topic of Cummins in Memphis- never, ever, EVER buy a reman'd turbo from Cummins.

At least one that was reman'd in the US. Apparently their Mexico plant is automated.

Seriously though, don't. I know I never will.

Shouldn't I just add Propane and be done with it?

I'm more fan of air to air coolers .. coz they are extremely simple and nothing more than initial cost of product and instalation asociated ..

then the air to water coolers that have another water system and to much water close to the intake route ..

Then drive in to propane .. and yes .. propane it's a great option and actually you can source a bolt on kit that only will cost on propane tank recharche ( depends how much you use it .. )

Like apple pie or cheescake .. I like both .. but usually buy apple pie as my favorite .. but nothing wrong with other options . .

If you think you like propane and have a propane soorce easy and close to you .. nice .. it's like ARB instalation .. one time good air instalation and never be worried again ..
 
food for thought- aren't air to air are more efficient? the water to air aftercoolers can only cool the charged air with water at temps of +190*(using the coolant that the motor uses, which i believe is how your system works on your 4bta) unlike the air to air that has a much better cooling rate using ambient air(assuming your moving and its not 150* outside).

It depends . .. the size, where are, the outside temps, kind of application, speed throught etc ..
 
Dan,
sent you a text message . . . your front U-bolts, from the pics, it looks like you just made new spring perches and used conventional U-bolts (U shaped) to hold the axle to the springs. Can you post a few more picks of this?

Also, what was your pinion angle and did you use Marlin's Hi-steer arms? Since we have the same front end, I need to get some arms for my rig.

After enough poking from Mudders, I changed the nuts on my U-Bolts to self locks and cut them off.

My pinion angle will be different than what you need since I am running a shackle reversal and my front springs are moved.

Arm rest got upgraded this week.

Little one is going away to a new home.

Started on the steering and had a bit of a set back.

I had a slight oil leak from the pump area. I thought I did not tightten the oil feed line to Wabco or something. Nope!

I pulled the assy and found the seal was cocked in the housing causing the oil leak.

I also noticed the drive gears were really worn.

Lots of life left there! Its only 1/3 worn through :hillbilly:

Thanks for the info. Should be getting the rough stuff 60 series SOA perches in the next few days. I think I am going to talk to Marlin about his hy-steer kit. I can get the 60 series kit, but I will need a custom drag link since mine is longer than a 40's but shorter than a 60s.


Your hydro is looking sick!
