Starting to get parts ordered to start my build out on the the motor. This is going to be a daily driven truck that I will be towing another truck to events. But I will be unhooking from the gooseneck and racing and dynoing it also. Want input on guys that have ran the 62/71/13 or 62/65/13 over a S400. I know the S400 has a limit to about 700hp but it is a great, cheap turbo that tows great. But i want to know which exhaust wheel on the 62 will be better for towing and drive pressure. I run just a Smarty TNT and stock sticks for right now and will be going to F1 later when someone wants to sale their Flux 3's. Mainly just want to know if someone has used both wheels on their truck and how they was different on the street.

62/65/13 over S475 should be good air and good spooling.

s475 new can be picked up for $500-600 new.

Still trying to heal from my hip surgery.

I have physical therapy 3x a week for almost 2 hours each time.

The Dr. wants me to do work hardening for 4-8 weeks. That means that its 5x a week 4 hours each day.:doh:

I might as well go back to work.
 
Fireman, give us a shout and we can make some plans for your charger. Chris
 
I want to do twins in the future also. I have a 62/71/13ss for a single now, no way I would want anymore lag. I could deal with a touch more but that is it. Go the 68 turbine route. Never talked with ED but that is what I would do. I think a 65 would have too much drive pressure if pushed hard.
