Truckers, lets see your rigs!

All 4 manifold turbo mounting studs broke might be why it only made 30psi boost. Also MAY have a coolant leak........

Good thing it wasn’t a single turbo truck or he would have ran over it since the pipes were all that was holding it on.

The naysayers would say if it were single turbo the studs wouldn’t have broken.....
Going to delete the precooler, or?
 
It's the cooler mounted to the block, supposed to cool in between the low / high pressure turbo

Seriously?

You know he does understand what the cooler does.

It also isn’t between chargers, it cools the air before it enters the air to air, hence why it is called a precooler.
 
I’m lost in the Stone Age with our old stuff. What is the purpose of that cooler.



Air to water intercooler. Removing it raises boost temp at the intake temp sensor roughly 10*. However it lowers water temp by the same amount. I’ve never checked this on a stock truck but when I did my 2006 probably 5yrs ago that’s what I saw and it’s 800hp. I can only assume the boost temp is cooler with less fuel since I’m maxing out the useable power out of stock turbos.

Air temp was in the 145* range with the pre-cooler with a stock W9 charge air cooler. With it gone I saw about 154* max changing nothing else. This was on a 90* day on a long pull.

But with my C18 I have thermocouples in the inlet and outlet of my charge air cooler and I found the stock temp sensor in the head the ecm reads is sometimes 20* hotter than the air going in.

Got 9 of these coolers holding a pallet down now. The cores are $750 each
 
Ok I though the air to water intercoolers got phased out with the early b models in truck applications. I didn’t realize the acert used them ahead of the cac.

I think if they were like the 6.7 Powerstroke and used a separate cooling system for the ATW it would be more effective. I’m sure it wouldn’t justify the complexity.

Well he asked the question, so?

And sorry for the misinformation
 
Doesn't help that 2 CEO for hit with fraud charges and 42M fine earlier this year and now they can't get operating capital finaced

For sure! I was reading about it today a little bit and from the sounds of it they had 6 months to get the company back on track. According to the financial analysts it was a long shot to begin with and obviously they failed. Guess there will be 2700 fleet trucks to hit the market soon.
