25psi + Inlet air temps?

[Aviationterry]

Hey guys, I've got '93 manual VX 1HD-t,
Just upgraded to a Gturbo grunter extreme.. I'm currently engineering my own water to air intercooler setup.
I've got full 3" exhaust and modded intake. Also a couple fuel pump tweaks.

I've been running an intake air temp for a while now and with the boost pushing up towards 25psi the air temps get up towards 150 deg C.
Averages around 100 cruising at say 15psi.

Now this has only been during testing and I'm not really using the truck till I get this cooler sorted..
but what realistic inlet air temps should I expect with a decent intercooler setup?
Have any of you guys logged these figures etc??

Thanks in advance

Terry.

are you aware that your intake temps will depends greatly on your ambien temps, humidity and usage ..

 

[Aviationterry]

Yes I'm completely aware of this.

Just after a rough idea of what to expect from a decent working intercooler system??

Average day here currently is about 25 deg C and say 60% humidity.

And, the more boost you generate , the more increase in temperature of the boosted air charge.

Hey guys I'm not after lectures on air charge density and temperature relative to compressed air pressure ratio etc. I do realise the factors. I'm an aircraft engineer by trade and have study this

Just curious to see who has monitored and realised these figures and effectiveness of a working stable system...

Am I likely to see say a 50% reduction in intake temp?

I never measured the temperature drop across my cooler, but coming from another guy with a very similar setup to mine, with the Cross Country Ultimate, he was seeing pretty close to ambient with a 900CFM SPAL fan underneath it, and on a cold morning coasting downhill for a while, temps around the -5 to -10 celsius mark.

That's awesome. So is that a top mount air to air cooler setup?
I'm currently a bit torn on what to do exactly. Complete the work I'm currently doing on the water to air setup or just buy and fit a more simple top mount air to air.

I'm also running water/meth injection.. and electronic AEM kit. And that seems to help out a lot.

Yep, top mount air-air. In hindsight, if possible I'd go front mount if I was doing it again, a top mount is in the way for just about every engine maintenance job there is?
