Pros and cons of a 64/71/16 or a 66/74/14. Any input is much appreciated.

i would do the 64... and do a 64/71/14 to keep the spool in check that setup will net about 850-900 all day long with the right fueling.....

a 16cm housing on top would be very laggy

Im not sure on what fueling that you have but the 66/74 is going to be laggy compared to that special. If your going for all out dyno queen then you might want to go the 66 route.

the spool will be super fast but worry about drive pressure issues with the s480 on bottom, if your doing a 480 at least do the 71 wheel. Its kinda like my setup i have a s362/65/12 over a s475 spools stupid fast but i am worried when i put the 150-175's sticks in if the drive will be through the roof. right now its about 75 to my 65 psi of boost which is not bad, but we will see....

If your only wanting 90's then a 64/65/13 over a 75 if your going to do bigger sticks then a 64/71/13/14 over a 75 or 80 drive will be good either way i said......

I love my 64/71/13 with 480. I loved my 62/65/13 but drive pressure was a consern and also too fast of spool up.

You wouldn't like it if it kept breaking transmission parts every time you just drive or get power. It just puts so much power to the ground with a tight converter and broke so many parts. You seen my videos where my truck took off fast on top end with that setup.
With the new setup, it spools fast and EGT's are cooler in every way. Really going from 62/65/13 to 64/71/13 didn't make a difference. But boost went up.

Your not making any power, thats why :buttkick: :rof . Well as you seen from the movies, the truck makes power so fast. It was just too much stress on shafts and clutches. 3 transmission parts broken in 2 months is something. I leave my Torque Management on 1 on Smarty TNT/r and don't get on it from the get go. I only get on it passing cars on freeway.
This new setup is really weird as well. I thought it was going to slow spool up, but with Shane's Mafia Nozzles and the Loose converter. This thing just goes 5psi-80psi in a heart beat. I will post videos very soon. Trying to work on other truck in a bit and have the new clutch installed into it.
