Truckers, lets see your rigs!

Theres a block girdle that goes between the pan and block to help stiffen it up, it would definitely be useful at that power level. My experience with B's has not been great so I'd suggest just going to an electronic and being done with it, but that's me.

Yea. Theres a bit of a talent deficit around here lately

[Feed Bunk]

Looks like those northern dump truckers need to start using outriggers.

Hauled some hay the last 2 days.

Anyone here put some descent power thru an allison 4500 with any success?

[biggy238]

I need to check, but I think the Oshkosh HEMMET we had from Ft Campbell is a 4500 behind a 700hp KRA engine

Tuned 871 if you consider that “decent power”. What year?

[Rig Wrench]

Its an sdp 475 currently. Thinkin 600+ bald eagle range if it wont phuck the trans

[JWhite]

The 4500 is a good trans, they've been put behind a c27 in certain applications (off road)

Well looks like my cat cooked down again. Coming back across Nevada today all of a sudden started shaking and light grey smoke started rolling out from underneath. Hit the shoulder right away and sure enough smokes coming out of the dipstick tube and the blow by tube. And it's missing to beat hell.

I limped it another mile down the shoulder to a rest area. And started looking it over. #5 injectors completely dead not firing at all. Oil looked ok and coolant is clean. Pulled the valve covers and fired it up hoping to see compression coming from around the injector but it looks like it's coming up from the oil drain holes under the cam. Checked injector wiring which looked good. And everything in the valve train looked good.

I'm figuring the injector went and overfueled and cooked the piston but does anyone have any other ideas? Just overhauled it 3 weeks, 12k miles ago. Egt's didn't go over 1100 post turbo and coolant never went over 120° today but it was 100° outside. Stock overhaul running a 550/1850 file, marine cam, stage 1 turbo. Nothing fancy, no check engine light, no codes.

1100 post turbo on a non acert piston?

Thats like 1350-1400 in the manifold, that is bad news for an aluminum skirt.

[ktllc15]

Not sustained at that temp it Usually maxes out about 950° and at 1050 I start lifting my foot

[bracker8040]

Man, that’s bad news!
950*-1,100* post turbo is really hot, IMO. We’ve seen 300-400* difference between pre and post turbo. That means you’re looking at a possible egt range of 1,250*-1,500* in the manifold. I tell guys 1,250* pre turbo egt as long as no other fluid temps get outta range. Anything over that better just be a short burst.

Easily handle that, change shift points to performance instead of the usual "economy".

x2 aluminum skirts need to go away.

Mybe add a second turbo

Well if it’s all stock except a cam he’s either got a boost leak causing heat or a hot injector, both of which helps kill those skirts.

Sounds like one if them just did...
