650 Horse turbo

[x MadMAX DIESEL]

Both an S472 and twins can reach get you to this power level. But besides spool up time are twins really so much better? Safer for the engine or what?

I really don't care about MPG or spool up time (as long as I have enough power to drive around with) Pleny of you have twins but I don't think many of ya have a 72 as a single... If you do I'd really like to hear how you like this for a DD

I have a 472, I don't drive it everyday but I wouldn't hesitate to...
Egt's are a little high when lugged on hills, and is a bit smokey off
the bottom but other than that I have no complaints.

 

[x MadMAX DIESEL]

I don't mind alittle smoke, I think I can jsut downshift it gets too bad anyway. What else is done to yours injectors? and what? or is spooling fine with a stock fueling system

 

[Gmclbz]

40% Dippers and a level 3 wicked pump

Whats the a/r on yours? I was looking at gettin a Bullseye. I'm not sure what A/R though

 

[Gmclbz]

.90

Intrested in results too:thumb:

I have one but shes a bit loose on the exhaust, 1:32 88mm turbine, T-6 flanged

Race cover too

I'm also getting ready to get a S472. My first thought was an S475 but I was worried about lag. My tuner says he can raise my shift points a little and the S472 will spool fine. With my stock turbo I peg my 1600* pyro quick on a max effort tune. Anybody know what I can expect to see at the end of the 1/4 with the S472 ?

converter plays a role in spool up too

I'd be interested in the bold question too. Are you planning on goin with this while you have your stokc fuel system? I am.

i wouldnt use that as a single for daily driving

Yes, stock fuel system. If anything I'll do injectors but just to help with safer tuning. Also converters were mentioned, It looks like mine may not be the best for spooling a large turbo. I'm hoping maybe good tune will help it lite, but I really dont mind some lag, I run an economy tune most of the time for my dd tune and its sluggish.

Well i know steve on here has a s472 with a A/r .90 and that thing hardly has any lag. Hes run a mid 12 and 620 somthin in hp on a weak cp3. Only reason i went with twins was for towing and being on 37 with stock gears.

 

[sweetdiesel]

Egts would depend on fueling level.

If you where to say run 3200pw with stock inj. I would guess around 1400-1500

I ran 40 overs with a 2400 pw and they where 18-2000 with a 475

Nothing will be better for gets than twins but I wouldn't hesitate DD a big single

 

[Righteyeblind]

I had a S472 and took it off real quick for towing reasons. It was crap to tow with. As a DD turbo I didnt think it was very fun except for wide open then it was a lot of fun. 1.0 a/r with a 1057 converter.

 

[Mike_S]

I was daily driving with a stock fuel system and an s480 with a 1.01 a/r turbine housing. Not bad for daily driving except for copious amounts of smoke. Rather laggy as well, but i am used to tradeoffs. With a 3200 pulse width on stock sticks I could manage about 1400 degrees unloaded, but if the engine was lugged it would skyrocket pretty fast. I would say if you are not gonna tow with your truck I wouldn't be afraid to run a big single as a daily driver...but if you will ever need to tow I would steer clear.

1300* through the traps for me.

Those are some good temps on a full throttle run, also you guys mention that the S472 would'nt be good for towing. I tow a 4000 lb. welding rig a few times a week normally only a few miles to do a job, I'm hoping with a trans tune this wont be a problem. Also I have a fifth wheel camper that weighs 10,000 lbs that I only tow 2-3 times a year. I'm pretty sure I'll be fine with the 4-5 k loads and I really would hate to down size my turbo plans just to tow my 5th wheel a few times a year.

 

[Akdiesel]

I would go with a S466 or S464 if you tow at all...plus you can VERY easily upgrade to twins from there

You should be able to get away with that...
