Default Quickest time/trap on VSR S480?

Just curious how far I can push the T6 S480. I know the "real" S480s have gone well into the 160's. Haven't seen as many "fast" VSR S480s.

Seems to still have some left at 158 and 3000ish. Wasn't picking up much from 22 to 24lbs on a 4.8 around 7k.

Probably the record for this turbo.

Not sure about "fast" as its a street car but the older VSR S480 made 850 on 18lbs and 1050 on 22-23lbs so didn't seem tapped out just yet. Same dyno 1,100 was enough to trap 165 in a heavier car so I'd say yours should have some left.

Forgot to ask but are you still rpm limited, or did you manage to wind it out some?

At 7200ish now. Assuming my .660 lift dual BTR springs aren't happy with .600/.575 lift cam. Going to shim them a bit and go after more rpm soon.

haha that would be terrible, we send those springs to 7500+ everyday. I've used the summit springs for 7800+ as well, no signs of falling off with either one.
