turbo question

What turbo would you guys recommend. All my info is in my sig. Id like to run a single that would support 600 plus hp. I dynoed 603 with the twins and don't wanna lose a whole lot by going to a single. It is a street truck that I drag race with so it has to be semi street friendly. I was looking at htt's 66mm comp, 16cm stainless exhuast housing and industrials silver bullet and one of scheids lightning turbo. Does anyone have one of these and how do you like it or what would you recommmend. I heard that scheids turbos are over priced for how they perform. Now my truck is an auto so I do know I can put a higher stall in to help it light something if it is kinda lazy. Let me know what you recommend. Thanks guys.

My truck:
1999 Dodge 24 Valve Cummins
P pump conversion with a 180 pump
Pump doesn't have a fuel plate, 4g springs, & full cut dv's, no afc, ect..
.093 fuel lines
Air Dog 165
custom ground cam
mahle pistons with .050 valve reliefs
balanced rotating assembly
8 x 11 injectors
ported head with 60lbs valve springs and 12mm studs
Pro 52
Polydyn header
stage 5 east coast diesel bullit automatic trans.
triple disk dunrite torque converter
4.10 gears
klienn train horns
Nubers with the twins and without header
603hp 1157tq
12.7 quarter mile (then ht3b blew again)

I got a pro 52 on the way. It was only 1200. Sledpuller500 (eric) has one on his common rail and he made 604. His is a stick but ill try it anyway. See what a big singles like before I drop 2k into a htt or something else. Still would like to know if anyones using something like that as a single and how they like it.

My buddy ran a pro52 on his 99, with a drag comp, and mach 5's, and it did alright. However he switched to a sled puller 66 and felt it was an improvement. The big thing about those, is that they run a 4 9/16ths exhaust outlet (read spendy) that flange and clamp will run you about $170 plus anything else you need to fab the down pipe. Also, you will need to get an adapter from the stock t3 flange on the exhaust inlet. I'm not sure if the pro 52 is a T4 or T4i flange.

Are you interested in selling your twins?

I actually gave them back to east coast and they refunded me. The downpipe isn't an issue. The local machine shop is going to turn the housing down so I can use the hx40 downpipe. He's only gonna charge me $80 to machine it too. Bad *** if you ask me. I might have him cut the flange down to a t3 flange. He said that's like 300 though so maybe ill just use an adapter plate.

80 bucks to turn it into an hx40 style is a good deal. As for cutting the other flange down. I'm not sure if there is enough material there to make that work or not. I'd say run the adapter plate.

I see you hooked up a wastegate. Where did you get it and what all is involved in setting it up. I heard its pretty tricky.

I run a tial 38mm gate. I got it through a friend that builds little ricers, he hooked me up with it at cost. Anyways, with all that said, hooking it up wasn't too hard. I built a full size adapter to run between the exhaust manifold and the inlet to the turbo. Then bent up a piece of 1.75" tubing notched it out for the 3" hot pipe and notched a corresponding hole in the hot pipe. Then jigged it all up on a stand I have, because the relationship between the adapter (therefore wastegate), the turbo and hotpipe wouldn't change between the stand and the engine.

Getting it tuned has been tricky and has been a lot of testing and a combination of different springs and a wastegate adjuster. The nice thing is that the wastegate has two adjustment ports, so boost pressure can be used to either add pressure to the top or bottom of the diaphragm allowing for great fine tuning. Right now I have it set at the drive pressure I want on the top turbo to keep it spinning at an approx. PR of 2.3. This seems to work pretty well for me, but I'm sure that there is more fine tuning that I could do as well.

I choose this PR because it's right in the turbos map, and assuming a drive pressure ratio 1:1 the resulting opening pressure to achieve this is at approx 18.75 psi drive pressure.

Hope this helps a little if you're planning on running one.
