Slim, my buddy with a 6.2 said his truck ran consistently hotter EGT wise before he put his turbo on. He had the fuel turned up some before, and of course he does after as well, a bit more I think. Him and I get similar mileage sorta, and our trucks do pretty much all town driving. I usually get...

Sounds like a good idea to me :) Where would this take place (where are you from)?

I have noticed what you said about the drive:boost ratio changing. As the VGT opens, it seems to get closer to 1:1. I would imagine with the extra fuel I will have I can probably leave it maybe halfway open, and see how it spools. I want it to be able to spool pretty quick but be able to open...

Agreed. You mentioned before about exhaust housing size, and I am trying to find some more info on the HX52 and HE351VE. I found one place that said a HX52 is a 16cm exhaust housing, is that correct? Also, what is a HE351VE, 14 cm??

Any chance you might be interested in selling one? :) buddy, that makes sense now why when I hear alot of them 6.0s start up they whistle like a vacuum before sounding normal, must be the VGT cycling. Another thing that might help with spooling a non WG turbo would be a better exhaust system...

Some quick searching I found that they are VGT turbos. I knew they were variable something, but I didn't know exactly. Probably not worth the work assuming what I have is better. You are probably right with the problems but I don't know, I guess they had the first VGT.

this thread is a good idea, I will again apologize to 6.2 turbo for derailing his thread, sorry! Anyways now that you guys have mentioned it, I have been thinking about turbos again, and I came to a similar conclusion as buddy, that a large non WG turbo could do pretty well on a well fueled...

Alright thanks, good info to know!

I see, that makes sense, I will talk to Gary tomorrow. I would assume the exact location of the grooves is not critical right? HX 52, that sounds like a pretty big turbo, is it wastegated? What truck/year did that come off of?

Alright thanks! I think Gary is starting on the plungers this week I may give him a call and let him know about these grooves. Are they like a semicircle profile? Thanks again, and turbonator, I am very interested in this supercharger idea. I also looked up the s-400 that you mentioned...

Oh ok I see, I was doing some quick searches on youtube and found quite a few vids. Turns out I was thinking of Toyotas they were outfitting with supercharged 6.5s, a company called bullet diesel. Seems like a cool idea, I would like to see it done. So does boost rise linearly as rpm increases...

Now that I would like to see. I don't know much about superchargers other than they are belt driven and provide instant boost, but how much boost can they run? Plus can they flow as much air as a turbo? A while back I remember reading an article in the DP magazine about a Dmax with a...

correct this is the OEM turbo off a 6.7. But you make a good point slim. I do have a pressure gauge plumbed into my crossover so I am monitoring drive pressures now. Of course, the VGT is a very large turbo, or at least it seems to me. Now I know I am not running it at the boost it was designed...

I think I will be happy with the size, we will see I guess :) Actually Slim, I am running a Holset VGT like turbonator has/had on their pugg, I have had it on since March, before the rebuild. You are very right though, the GM-x turbos gotta go when you really want performance. I know what you...

6.2, I didn't realize there were different springs, is it stamped on the spring? Also I didn't really think about the metering valve, that makes sense that the plungers do not reach full travel because the valve controls how much comes into the pumping chamber. I have a question about the...

Yeah I actually had the water pump go out two months before the planned rebuild so I installed a pump from a year 2000 6.5, along with a new fan clutch, and a plastic fan off a Duramax. I believe the rad is not too old, i think the PO had replaced it. It runs right around 190-195 (has a 190...

Agreed, I would like to do a WTA set up before I start injecting water/meth. I have been looking at the manual on stanadynes website, trying to understand how everything works a little more. Do you guys think a little stiffer gov spring would keep the gov from closing the metering valve as...

Aces, I bought them from GMpartsguy over at the place, he should be calling me back any day now to tell me they came into his shop. Unfortunately, these cups are apparently hard to find and need to be purchased from a GM "vintage" warehouse (isn't that sad?) so they take a while to get here. He...

Hmm I wonder if I should even have him touch them then. I may leave them go. I am thinking somewhere between .370 and .410 inch so hopefully I shouldn't run into the cavity problems. I agree Slim Shady, I was going to have mine machined since my pass. side head was running circle precups while...

I am having Davies precision machine do it. I talked to Gary Monday night and he remembered working on one a while ago once he saw the rotor. Anyways, I will probably call him tonight after work, as he is working the late shift. When I talked to him he said he remembers opening up some kind of...
