19 psi and 1000 degree EGT

[Goofyexponent]

I have actually worry about mine not getting hot enough. The highest I have ever seen was about 190 and that was pulling 4 wet round bales loaded onto a 5 bale hauler trailer. I have pulled a little heavier but I was beating the truck on that run. Now that it is cooling off a little I cant keep the truck above 150-160 to save my life unloaded. I actually have a huge piece of cardboard covering up about a quarter of the radiator with those temps.

Your thermostat is either non existant, or stuck WIDE open.

I had the SAME problems, but I got sick of it and I went at the truck with 4 gallons of concentrated coolant, DCA's, new thromostat and gasket. I soon found that the thermostat was stuck wide open, hardly allowing my truck to reach 170* with the grille cover installed in above freezing temperatures.

Change the thermostat and the coolant...be sure to at least TRY to get the block drains out (I got lucky and mine came right out!)

I didn't read the whole thread, but man I don't know how you accomplished 19psi on a wastegated turbo. Not to mention 19psi and only running 1000*EGT. Its been a long time since I have been on this forum so could ya update me on your setup? There's no way you're running that kind of EGT without a very efficient intercooler.

I have no intercooler whatsoever, i have a unknown IP with th high rpm spring in it maxxed completley out, timing unknown but sounds advanced, BB codes pop pressure at 2300 psi, ram air intake, home made downpipe factory turbo system wastegate is unplugged and wired shut, pyro is brand new autometer its in the driver side exhuast manifold, comming up the mountain i can hit 20 psi at 1100 egt, flat ground its 19psi sometimes touches 20 on cold mornings but at 1000 degrees EGT,

I know the gauges aren't lying i have tryed a few different boost gauges, the turbo sounds whicked when it passes 10 psi, and i am smoke free pass 10psi, i dont see why you dont think a wastegated turbo is capable of that much boost? they spool so fast because of the small exhuast housing and they wont quite spooling when the wastegated is disabled

It'd be nice to get a video of your engine revved up. I want to hear the turbo.

I will take one next chance i get, the camera dont justify the whistle if you could hear it in person you would swear a 6.0 turbo was on the engine, its crazy how much whistle and whine there is but the camera wont pick the biggest part of it up,

And i guess i need to make a video just to prove what im saying i know there is some people out there that wont trust my words

Lol no I trust you. I just don't know how its mechanically possible. Yea the wastegated turbo has a smaller exhaust wheel and will spool faster because of that and when you wire or weld it shut it will boost like a non gated one. But I blew the head gasket out of my bulletproof 6.9 in my brown truck running only 15psi boost. And that truck would run over 1000* if held down to the floor for a quarter mile or more and I have the biggest intercooler of anyone in this IDI forum IIRC. You must have a VERY efficient crossover pipe and down pipe or something, the only way I can see you running that cold is if your exhaust is flowing VERY freely. Aside from making the crossover pipe larger or making the exhaust crossover route shorter, so that the exhaust flow enters and exits the turbo sooner, I just don't know how you're doing that.

I'm thinking you have some seriously major boost creep or something going on. When you start building turbocharged gasoline engines you really start to pick up allot more in the sense of understand how turbos run. Sometimes something that looks to be a great running turbo setup can actually be the turbo over boosting itself because of some freak problem. Such is in the case of my Eclipse just a month ago. I installed a 500+hp engine in it this summer, slapped on a forced performance Big28 turbo with a ball bearing center cartridge, big cams, the whole works. When I got the motor in the car and got it running with a decent base tune the thing would smoke tires in 3rd gear running only 18psi boost. After a week of driving my 18psi went all the way to 35+psi and I found out my muffler had clogged up in some crazy way that made the exhaust gasses velocity speed up after it passed through the restricted area and that would cause my turbo to spool up WAAAY beyond its efficiency range. anything over 25-26psi out of that Big28 will kill it very fast even with my custom ball bearing chra. I had to fix that problem quickly or quit driving the car. I opted to quit driving it because I didn't have the $700 for a new exhaust.
I hope you 19psi isn't because of some fluke thing like that.
The only reason I'm so skeptical/worried is because I've just never seen or heard of anyone running anywhere near the boost you are with the crazy low EGTs.
Definitely get some vids. I'd love to see this thing run!

Were all dying for the day we get on here and see someone with a hopped up idi that we can duplicate their success.

Your not going to build much heat just pushing along a standard cab pickup. Put 10,000lbs+ behind it and I bet then his EGT's go up. Unloaded I can barely get upto 8-900*. With one of my trailers loaded, I can hit my max of 1200 at 14psi.
I don't doubt his readings at all. I know with my wastegate hose unplugged at 55mph half throttle the engine will peg my banks 15 psi gauge. I normally run 13-15 but that day the hose popped off and the truck started running out from me I was shocked to see the boost gauge that high but immediatly realized what happened. It really is tempting to crank the waste gate closed but I need to hook up a higher reading gauge first.

I agree

I think the reason for his high boost/lower EGT is because he is running way more rpm than standard, and he is underfueled. I tap those boost numbers with my wastegate still functioning, and engine under 3000rpm.

 

[Black dawg]

the most ive seen out of a factory turbo is 18 with functioning gate between 2000-2500 at 1200*

 

[6 Nebraska IDIs]

Dang. I guess I never knew you guys got those boost numbers from the factory gated turbos. I thought I was doing GREAT at 14psi on my custom 088 setup. My engine pulled CRAZY hard at 14psi, I can't imagine what it would have ran like at 18, 19 or 20psi. I had mine barking tires shifting into 3rd, and on a day when the pavement was wet I actually broke them loose and the back end started dog tracking and left a double patch of black marks.

WOT I can tap 16-18 around 2200-2400 in 4th, EGT's will creep up to around 1000-1100.

I have already purchased the parts to upgrade my turbo, just waiting for a chance, as I'm about to go wheeling and need it to tow.

Compressor housing for T04Z, 84mm-63 trim wheel, COMPRESSOR HSG .70 A/R, T04S style with 4" inlet and 2.5" outlet

The inducer measure 66.7MM, and the major 84MM.

this setup will actually be big enough to feed my 6.9 unlike the current ATS turbo. I will be using this new turbo paired with my 02 7.3 SD intercooler. I will be running the wastegate set at 22-24psi.

 

[Black dawg]

the boost number can be a little misleading because of boost/drive pressure ratios. a not gated turbo has a much better boost/drive pressure relationship.
