s480 twins
What are you running on top of your s480? Im going to make a set of big twins wondering what is working for others. I have a small set that have been great. But at my hp they can no longer keep up with egts. Im shooting for 1000+ and still be able to use every day. With the electronics of these truck i feel this is a very save hp level to go after. And i feel it can be done with this turbo on the bottom. Just wanting something that will spool ok on the top. Trying to find the best of both worlds.

A 480 will not do 1000 on fuel only . 928 was the most I could do with it. You will need more primary turbo, even some 88s will not do it. If you are content with 900hp a 64/71/13 over s480 with a external gate around the 480 does well. Tim

I was wanting fuel only. But im not scared to spray the old girl if need be. I am sure if i sprayed her know she would get close but would kill a turbo in the process! I was looking to run a 66 over the top of the 480! I really thought that would be close to what is needed to hit my goal! Thanks for you input!!! I will be playing with the big dogs soon! I am porting and building turbo this week. Porting is done starting on the turbos wed. s480 will be an 80 to 85 mm.

1000 hp fueled daily driver not many around. I'd go with pretty new territory.
As others have said 900+ has been made with 480 and a big secondary. You can't go wrong with that combo.
I run the 64/71/13ss and 480. Egts are very respectable hitting 1250. Steet running 750-850, dynoing 1150.
Spools good, makes very nice power.
