Performance mods

or you could join the real power players and ugrade to a Volvo motor

 

Oh trust me mate, there are plenty of boneheads here doing half ### jobs or less.
He got lucky and met the Cat power Guru of all time to teach him.

I'm nt going to answer for him but I know he is getting much better MPG now then when the motor was stock. (as long as you can keep your foot out of it)

 

MM is right, i use to get horrible millage stock no matter what i did, 4.1mpg and not any better. I get 5.5-6mpg now making this kinda power.

If it wasent for Kurt, the CAT guru id still be treading water with my head up my #$$ wondering how to get better millage. I had to swap ECM's, this is the key with the bridge engine. Them ecm's are so retarded that even with colder thermo stats it ####### timing really bad causing hot water temps, this is for emission purpouses, cold motor bad emissions, hot motor better emissions. Same goes if you do straight pipes and get rid of them nasty catalytic converters, it starts to retard timing after a while.

The beauty of a modded engine is going half throttle and doing better than you were full throttle with a stock engine.

Trans is a eaton RTLO18918B, diffs are eaton DSP40's 3.55 ratio 40k lbs rears

 

ANd those hotter temps is why we are seeing so many motors with 400k and fresh overhauls in the truck papers. I wear they are drop kicking us right back to the 80's as far as engine reliability and fuel mileage when they should be going the other way with our fuel costs like they are

 

Now tell him what kind of fuel milage you get when you go racing the 16yo kids in there rice burners though

 

Exactly, "these new engines are designed to run hot". My #$$ at what price? Man my motor when stock would run 1200*F on the pyro pulling hills in high elevations. Thats playing with fire, CAT told me thats normal, once i realized what a bridge engine is i just had to get rid of that #### ecm for a pre emission one. Now i will hit 1200*F lugging at 1200rpm if i keep the rpms up she stays nice and cool.

Man the #### fan on newer 2001 and up C-15s is set ti kick in at 217*F, thats to hot for me.

LOL i got about 5 gallons to a mile id bet. You shoulda seen the smoke though.

 

Was that your strategy, smoke em out till they couldn't find there go pedal?

You know if you ever listen to the Cat informational cd about them motors they tell you to "let it run down to 900rpm, it won't hurt this motor"

 

Yeah right lol. My buddy has a 03 with 350k miles, he just put rods and mains in it, due to lugging it. Might not hurt a acert but you will be picking up U joints and tranny pieces of the ground, especially if your loaded.

Nah them ricers actually cannot keep up at highway speeds, one actually has some turbo honda that runs 13s in the 1/4 and he can hang with me up until about 100 or so then he pulls away. Im tellin ya once boost kicks in it will pull to the right BAD bobtailing you better hang on to the steering wheel.

 

lol, I've gota get up there for a visit. I wana drive that thing
