Sounds like the top gate is a bit too tight if your only getting 27psi from it. You should be around 36psi.I'd back it off 1 1/2 to 2 full turns and see what it does. What are the splits like on the street?

Flux 4.6's. They are awesome. Even running around at 750+, the smoke is 100% controlable with the right foot.
Turbos are HTT, 64/13 stainless and S480. According to the dyno software, 75mph - 125mph happened in 2.1 seconds, and in that short time the 480 only got to 26lbs of boost. If i could load it harder, or find a better setting with the wastegates I am confident there is fuel for a little more. I am seeing about 38lbs from the 480 on the street.

Nathan, on the street I get about 70 lbs total with about 38 or so from the 480. I think i need a stiffer spring for the 64, and then i can back off the external some if i need to later.
I cranked the 64 wastegate tight on the dyno, but the 480 just didn't come alive all the way.
Still workin on it...

Nice work!
I think there is more there!
You should be able to get very close to 900.
Congratulations!
How do you like your Ultimate?

Yes over a S480 with race cover. Nope it was on a Dynamic Dyno (load cell). We got alot of power out of adj. wastegates. It just needs some time on the dyno as we ran out as we blew a hp line and fitting so we got 2 dyno runs.

Chris nice numbers. Did you have the tst on the truck? On Dunbars dyno adding the tst the way I told you added 12lbs of boost on the 480. My 480 on just a smarty would do about 27lbs add the tst and it will almost hit 40. Tim
