Truckers, lets see your rigs!

Tell them to bring it down here this Saturday. Hear they’re installing a European dyno as I type this.

FWIW I’ll sell mine for that. Lmao

Notice no picture of turbo side, wouldn’t want people to see the S400.
 
Well remember when people rate turbos it's how much power you can make with one for a few seconds, not how much power they can actually support working.

Glad i went last year then. Probly only muster about 300 ponies on a euro dyno

Yea Taylor doesn’t know crap about building dyno’s. When they get the transmission in direct and click on “start” and the computer takes over they are manipulating the numbers.

It would take so long to dyno each truck it would take the entire weekend if the operators didn’t preset the machine to go to 75% load when they start it.

Be like one of those 15min engine dyno videos where the operator slowing brings up the load. Be like watching paint dry.
 
Say at 70f and 3000 feet altitude, what's a good AIT to aim for at 40 PSI? Post CAC. I found if I went 95% throttle I would get about 1 degreef per second rise but above 95% throttle it would be 2 degrees or more per second and hit 160 quite easy.

edit: Should be well within the map but I don't know discharge temps, but I could estimate them.

Colder the better. Duh

When my IAT is 129 my turbo outlet temp was 442 so yours is hot as hell.

Contrary to still being in the map the compressor is moving out of it's peak efficiency range and super heating the air, this happens a lot with the 78mm used on the cats as well when guys use the 1.32.

So either the turbo outlet is hot as hell or the CAC isn't doing its job. There's a chance that the turbo is way out of the map too, but I don't hear any boost leaks. Can't think of anything else that would cause it to be out of the map. It's Duralite CAC. Air filter is new.

One thing is I have to fix up the rubber gaskets that prevent airflow around the rad pack. Maybe I should just change to a better system.

Matchbot suggests outlet temps of around 400f-420f depending on rpm for those conditions. I should put in a probe to confirm. But more boost, more heat or more altitude puts me out of the map.

I don't know exhaust manifold presure or temp., but I do know I can't really push things any more. EGTs can hit 1000 in the heat at altitude post turbo.

Maybe I should put a 171702 on for the summer :p

Just doing some tinkering on matchbot, going from 72% to 56% compressor efficiency will change outlet temps from 400f to 495f. But that's a pretty extreme example.

I just find it odd that such a little difference in fuel delivery makes a massive difference in IAT increase over time. We're talking going from say 36 psi to 38 psi. That's a very small change in the map.

I haven't noticed this before because I have more fuel in the tune right now.
 
It is a common problem with W900s to run high on the intake temps, and guys that have switched to the duralite have not shown any gains in dropping temp.

I can almost bet you are well over 400 at the turbo outlet.

I think these companies need to work on the end tank design as I dont believe that they are getting the air directed to all passages of the core.
