@ Hairy: Yea Ive got the HX35 and HX50 for my compound combo. I had a helluva time finding maps for Holset turbos, the ones I did find looked homegrown so I don't know how much stock to put into them. On my other computer I have a bunch of links saved to all my research, I hope to get it to come back to life. Naturally it decided it no longer wants to turn on (laptop power supply crapped out)
Since this thread had some rekindled interest I decided I best come clean with my project. I just feel akward having peeps think I'm doing one thing, when in reality its going a different direction right now. The twins are kind of sitting on the sidelines right now. My buddy who is the uber good welder (I am not good enough for this type of work) his TIG crapped out on him, and he just got a new job so time is really short for him to help me finish this all up. Between his time constraints and all the time constraints I've got I've lost interest in really getting this completed. I figured maybe all the road blocks were a sign that nows not the time to bolt this project on.
HOWEVER, I have been working on a possibly more simplified solution to my desire for low end boost. I bought an HE351VE a few weeks back on FLEABAY that is darn near brand new off a new dodge. I've built a homegrown actuator to control the vanes using a wastegate actuator arm. I'll load some pics later, I'm headed over to my buddies house now to work on it all a little more. We have to remote mount the turbo because the exhaust housing on this thing is MASSIVE and it's just too tight under the hood to effectively do it. Truthfully I have no idea if this all will work or not. It sounds somewhat plausible, the displacement motor these were designed for is not that far in size from ours, and I know alot of the 12v and 24v Cummins guys are using these turbos to support quick spooling 500rwhp trucks with great success. If it all works, and I can get good sub 2k rpm boost without EGT or drive pressure issues I'll likely ditch the compounds all together. If it doesn't work out I'll complete the original project. I figure I don't have a ton to lose by testing this one out.
I'll try and get a few pics up tonight, I'm headed over his house now to get a few things done on this project.
Man that is funny. I just mentioned that to hairy like yesterday. The way I mentioned it though is to use it in a compound setup. It will spool hella quick and you would have two good flowing turbos up top providing good cool boost. Also, if the wastegate setup closes too quickly, you can use a duel air cylinder that runs off of drive pressure to open it up and boost to close it. Using both would allow it to not slam shut. Here are a few pics...
Also the last pic is that Vgt arranged as a compound. If you have any questions as far as Vgts go just ask me. I have done so much research and it is the type of turbo I plan to eventually use along with my SC setup...
