Radiator Install after Hypermax IC Install

[tuckerd1]

What a job! When you install a IC from Hypermax you have to cut 3" dia. holes through the rad support and the rad bolt flanges. It make sit very hard to remove the rad. I had to remove the top IC pipe and partially unbolt the IC so I could tilt the IC toward the grille. It was very tight to get out even then. 2 man job.

Before reinstalling the new rad I cutout a lot more from the flanges before I reinstalled it. It slid right in without any problem then.

If you install the Hypermax IC you may want to do more cutting on the rad flange before completeing the job. Saves time and possible damage to a good rad when it has to be removed.

Thought you might want to know.

Good to know man, thanks for posting that up. I will eventually intercool my truck, so its good to hear what works (though I will be using a stock PSD intercooler)

Thanks for the heads up. I though a lot about the Hypermax IC, but I don't know if it will help me. I'm no where near the ceiling for EGT's, and I rarely see over 6 psi. I can get 8-9 with WFO on a hill, but again, rarely.
I'd be nice if Banks had different compressor and/or turbine wheels for these turbos, but they don't. May just need more fuel eh?

more fuel is always good!!! or maybe the w/g needs to be adjusted?

 

[hesutton]

The rod on my wastegate is as short as it can be.....no more adjustment left. I could just unplug the thing and crank to fuel up.....if I can. Need to talk to Ken at DPS.

I have been thinking about this with my truck. I have shortened the w/g rod and it helped but once RPMs come up, boost drops. I think what is happening is the exhaust is overpowering the spring inside the actuator and forcing the w/g open. I want to put a spring from the w/g lever to the bracket to see if it helps out.

or just a hand throttle cable for the same effect or dumping ALL the boost and mashing the throttle (blow a ricer's window full of smoke)

Mine does this as well. I can be going up a hill, WOT and be at 8.5psi of boost (unloaded), and once I get above 3000rpm's it will drop down to about 6.5psi of boost. I think its just because the IP is defueling as it approaches the govener.

did you happen to take pics? i'm installing my hypermax set up in a few weeks, pics for reference would be great.

X2 we like pictures!!

Let me understand this, If the wastgate rod is as long as it can get then the gate is open, dumping the exhaust?????????????? The best I have seen so far is 1 to 1 1/2 lbs of boost up a big hill unloaded and fuel screw maxed out.

My turbo is a T3/T4 Garett off a factory 94 IDI.

If you'll go Here you can see my IC album.

But this is the pic where the rad support is cutout for the IC tubes. If you notice where the 3" dia hole is above and below you can see the rad mount bolts. I cut away ~ 2" of the flange above and below the 3" hole. I didn't rmove anymore from the rad support, only from the flange on the rad.

That hole is a real issue for us non-A/C equipped early trucks. Our radiators are still where that hole is. Makes finding a decent IC to use difficult.

Mel,
Do you have the 37" wide radiator? Mine is 31"

I don't know about the ATS/Factory turbo, but on the Banks wastegate, you shorten the rod to increase boost, and lengthen to decrease boost. Jim, that seems like a low number as far as boost goes. Any leaks an the exhaust side?
