New 2.8L Colorado Duramax

[RI Chevy Silveradoman]

He NEEDS this upgrade. Lol

 

[BoostN]

You think we can get BoostN, interested in trying this on his 2.8 Colorado?

I think I remember someone loosing a rod using twins when the 2.8 first come out... but I don't recall who.

That's why you upgrade to the forged rods!

He was close to 700HP with twins and n20 iirc.

Good question Mike. These haven't been out long enough for any long term real life durability tests.
But I read or heard that they say they can get more from the setup, but that was the safe numbers for the application.
Interestingly, the company has AM Rods also. Lol

These engines have been around for over a decade now. Remember the diesel JEEP LIBERTY, same engine, just an earlier version of it. They've been used extensively overseas by several brands in all kinds of uses including marine.

I was referring to the twin kit out out by that company Ferman. Not sure how many kits they sold or the durability and reliability of them either.

 

[BoostN]

Now at two years of ownership. I'm setting on 43K miles.. so far, it's been a good one.

Replaced the factory tires at 40K. Everything else is stock and untouched.

 

[BIGR]

Sounds great @BoostN, would you buy another one like that?

 

[RI Chevy Silveradoman]

Nice Jeff. Thanks for the update. You put some miles on that. I only do about 12 to 14k max per year.
How about the fuel mpg update.

 

[Husker6.5]

Yeah, now that it's "broke in", what's the mileage like?

 

[BoostN]

Changed my fuel filters Saturday.



These had about 30K on them. Not bad actually... I was a little behind on it as I first changed them at 15K.

As far as fuel mileage, about the same really:

 

[RI Chevy Silveradoman]

Wow. I would have thought fuel mileage would have been in the 28 to 30 mpg range.
Are the fuel filters the cartridge type?

 

[Husker6.5]

Yeah, I thought the EPA had that rated at like 28 MPG 2WD, 27 MPG 4WD HWY estimate when they came out. Those look almost like the City cycle MPG figures the EPA had put out for it.

 

[Will L.]

Meh, the wifes 07 fj cruiser is supposed to get 17/21 and barely gets 16 hiway...

 

[RI Chevy Silveradoman]

What motor? V6?

 

[BoostN]

Most of those MPG numbers are 65-75% city as my interstate drive is usually stop and go +/- 30 MPH. I do work from home more often which helps but still not enough to show on the MPG front.

 

[ak diesel driver]

I was filling up a a gas station next to a guy who had one. Said he got 30 with it and he could tow his boat.

 

[Husker6.5]

Looks like @BoostN needs to take a serious Interstate road trip to get some accurate highway MPG numbers!

I've hit my best of 29MPG driving down to Florida, all interstate!

 

[ak diesel driver]

I should have clarified that the boat and 30 MPG aren't at the same time, just that it would tow the boat to his satisfaction

A serious road trip would be to California and back. Florida is just a little outing. LOL!
