Kind of in a toss up on the BD R700 set up or a 62/S475 set up. It's for my work/play truck. Pull a sled once a year and hauling cattle to the sales yard occasionally but mostly for racing around from ranch to ranch and fooling around with the friends. On either set up I want to buy 1 turbo 1st then lead up to my compound. For the 62 I was thinking the phat shaft 62/65/14 or a 62 FMW Box Stock, and the R700 to start of with the super b (57/65/14) any thoughts?
 
I should rephrase my question. What's a better all around set up? Can I still tow with the 62/S475? Any help is greatly appreciated, the 5.9L world is all new to me so trying to get a grasp.
 
I did a LOT of towing with my 64/ 475 twins, tuned to about the 500 hp level I could hold the pedal to the floor and never see 1100* From what I've learned your 62/65 would be better as a secondary than my 64/65 was.

Were you using the phat shaft as your secondary?
 
primary was an S475 with a race cover, 1.32 a/r exh housing, secondary was a 64/65/14 from HTT, if I had it to do again with similar parts I'd change the secondary to a 62/65/12 or possibly a 63/68/13

I have a lot of ideas as to what I would like to try, but that setup ran good and towed awesome, when I turned everything up I was knocking on the door of 700, nothing compared to what a CR will do, but ok with a VP I think.

Why the 62/65/12 over the 62/64/14? I'm worried about heat but also concerned if it will be slow spooling with the 14.

Also how did your VP Handel it I'm worried if it won't be enough when it's all said and done with the twins, along did you just go with ARP or have to o ring/fire ring it?
 
I'd go with the 57/65/14, then later down the road I'd get the 75/87 with a 1.10 housing...I run the 1.32 housing with the 96mm turbine, but if I don't run my smarty with my comp it's a little laggy and takes a little bit to get it turnin... but i can run 80 psi... then again sometimes i think my egts get a little high because of the smaller secondary...
 
I ran my 62/65/12 over a HT3B with my VP 24v and when I swapped to the p pump. I could start building boost at 1150rpm and never once had an issue with heat. If I had to do it agai, I would do a 62/65/12 over a 478, that way I could push the s400 harder than I wanted to push the HT3B and lower total boost.

I would go 62/65/12 and port the wastegate, because it would spool faster than mine did and should compound better than the 64 according to info I got from a knowledgeable guy.

VP handled it fine for 45K miles, only reason I had any problem was the relay for my FASS burned up while my fuel pressure guage was out for warranty. I ran ARP studs with O-rings.

O I never thought about running a 57/75 I'd be to afraid of it getting hot like you said, is that more of a pulling set up? And did it get warm at WOT or towing?

Also the S475 some what confuses me how many different sizes do they make? I want overall good spool up time and cool temps at WOT with the capability of towing with decent temps. That's why I was leaning more towards the 62/65/14

The 78 wouldn't be too big for me to pull with? I feel like that would be slow spool up even with the 62/65/12?

Ok so both you and headcase98002 say to go with the 62/65/12 but my only concern is once I do that I scarface higher egt's at wot when everything is turned up and I know that's what ill mostly be doing lol so I mean do I go with the 12cm housing to both benefit me at towing and driving around or go with the 14cm and have it only benefit me at long WOT with everything turned up?
 
I only saw 1300° may on a WOT run with my 6x.013's and a Edge Drag Comp wit am boost of 68psi, once I switched over to my p pump I increased my fueling so boost increased to 85psi as well as my EGT's(1500°) at WOT(cruising temps lowered).

Now I can't say anything about the 478's spooling capabilities asive never ran one. I rarely tow and when I do I can manage.

You shouldn't havea problem with EGT's.
 
How heavy are you going to pull? With my setup I grossed over 30K pounds a few times and I pretty much never needed to hold it on the floor. Also are you running auto or manual? Mine spooled pretty easy, only thing I didn't like was having to spool it back up everytime I shifted, with an auto you wouldn't have that issue.
 
What's your transmission? I ran 62/65/14 before I bought a different housing and wot a tight torque converter it sucked and I could get under it way too easy.
 
I have a 62/71/.7 right now. I plan on adding a 75 or 78/87/1.10 for my twins. Should be a fast spooling, cool running, towing set up for my truck. I tow almost daily and have no fear will work well for me.

Between 20-30k when I do, 10-12 cows in a trailer add up lol My Ford 6.0 with triple axle toy hauler fully loaded Is 25,000 with truck and trailer. So if my ford ever takes a crap before a trip that would be the farthest and heaviest I go that's longer than a 30 mile round trip. If I'm correct the 12cm will spool up faster reducing EGT's for driving and towing but be hot at WOT and the 14cm is the opposite?

I have an auto. So if you did it again you'd run a 62/65/12? I'm just thinking for when I add the twin how either or will affect me?

For my set up and what I'm trying to achieve do you think the 75/78/1.01 would fit me better rather than the 78? Also would the 78 run hotter and take longer to spool?
 
Yes, but if the .70AR non-gated housing is devided, I would use that and external wastegate. To me, the purpose of compounds are to get it to spool quick and keep that flow throughout the entire powerband.
