I should've heeded your advice even though I don't have any problems with my SCIII, I would feel more comfortable. Same with Nathan, I should've listened to him and got the bigger set, this is my 2nd and already wanting a BIG set. LOL.

Not to add fuel to the fire, but a big single can do it all as well. For one it is ALOT cheaper and easier to setup a big single compared to compounds. Next I tow with my S475 and don't have any problems with EGTs, granted the east coast is pretty flat and another DMax is typically my heaviest load - but this guy lives on the east coast and tows a 5K boat. Also you can get as much power out of a 3.0 single as you can a 2.6/3.2 compound setup. An S480 as a single would put you around 1,000hp, while as the big turbo in a compount setup 800-900 is the max before EGTs get out of hand. On top of all that many sled pulling organizations put twins in the unlimited category, meaning you are pulling against guys with open drivelines, drop boxes, and tube chassis.
Now all that being said, I would recommend 4.56 gears with the 37s. That will get you back to the correct RPM range, which will help with any turbo setup. If you don't plan to all out race the truck or sled pull, and have the extra money I would recommend a compound setup - for this application. With the right tuning 60% over injectors won't be an issue and if you can afford it SoCal Diesel is the place to send them. For the trans I would recommend a Stage IV build by a reputable shop, and I prefer the Precision Industries converters. For that setup I would charge $4200 all inclusive, out the door - I'm sure SunCoast would be alot more, but I am more of a drive. I could work out a package deal for the lift, tires, rims, gears, twins, trans, EGR delete, injectors, tuning, and all installed too.

4.56 for the front are around $280, and $170 for the master install kit with timken bearings.
The rear are about $390 for the gears, and $275 for the master install kit with timken bearings.
Installation will depend on the shop, but I would expect $300-$500 from a shop if you did not bring your own install kits, and they only replaced what was necessary.

yeah your right, but your not comparing apples to apples. the first part of your argument is that your s475 does this and that, not a 480. ask matt moon how his 480 is as a single. i think his exact words to me on the phone were " its a piece of shit on the road". he said he had to get a special converter that was really loose, a lockup controller, etc... you defintaly wouldnt be able to pull anything with it. i agree that a single is cheaper and less aggravating, but you cant say that a single is better by any means. the only way i would definatly rule out twins is for sledpulling. other then that, drag racing, towing, dd, they perform better. throw a cat 277 skidsteer behind a s4anything for that matter and tell me then how badass a single is. it wont do it. twins will. you went what 11.1x with 100 overs and headwork and cam. i think trent went 11.0x with stock heads, 45 overs, stock cam. so right there shows even at the dragstrip their better other then they cost more and can be aggravating.
Elevation makes us a little different when it comes to comparing turbo lag and towing , but ya Matts truck is way hard to spool with the S480 . My 11.0 run isnt apples to apples though , my truck was probably lighter than Dustins , but then again i was at a DA of 7400 ft that day so ? But I also think if i had a few tries that day I could have got another .1-.2 faster.
Look, I didn't say a big single was the right choice for everyone, I even recommend compounds for the original poster and what he wants to do with his truck. I was saying that an S475 single will hang with a truck that has an S480 as the big charger in a compound setup, and that a truck with an S480 as a single will make even more power than the compound setup. For your average guy that wants to get into the 11s it can be done for much cheaper on a single that can still do it all and tow, and for sled pulling the rules often rule out compounds as an option. An S472 or smaller with an 83mm turbine and .9 turbine housing can and will tow the skid steer with adjusted shift points and very managable EGTs, and an S475 will tow the loads that 80-90% of guys are ever going to tow. My 11.1 pass was the first 1/4 pass on that turbo, and not to get in a pissing match but how many passes and how much dial in time did Trent have in his setup before he got there?
Again I'm not saying that a big single is for everyone, but many guys think it greatly restricts what they can do with their truck while many of us are out there doing what others say can't be done.:hug:

1 pass only on dual cp3's and 45% overs , the rest of the runs all year were single cp3 and stock injectors . but yes the chassis was very dialed in .
Trent, you know I wasn't trying to talk down on your awesome accomplishments - you had a limited number of runs that could have been made at that power before something let go.
i wasnt trying to talk down on your run either, i think its very impressive especially since it was the first time out. in my opinion i dont think either one is necessarily better then the other overall, since they each have their own things they do better. i would say sled pulling- single for sure. towing-twins
drag racing- either.
It was also a hot day, and even by that time the temperature was still about 100* out there.
