That map looks like someone pasted a turbo map onto an excel spread sheet. That bullseye link shows their 72mm S400 at 89 lbs per minute, good luck seeing 120lbs per minute, I think the S480 with race cover is around 117.
That's not a 4LHR turbo, Schwitzer used to make the 4LHR and it was a replacement for this turbo which is an old Cummins VT-50. early 70's vintageSomeone correct me if Im wrong but from the pics that looks like its a reverse flow from the normal stock or aftermarket turbos used on our trucks.
Oh come on.... the 510 isn't that big......... okay, it's kinda big.

Has anyone here ran a "quick spool valve" like the one that sound performance makes?
Turbonetics can you PM or post here the specs on the Edge BB Jammer? Do you even have those? Got the Turbonetics name on the comp housing. I really need to find the correct specs so I can tune my twins properly.
I think I figured it out, looking at my other Holset maps the Mass flow is all in kg/s NOT Lbs/m, So if we extrapolate from the hx40 map I have, it looks like it would flow ~90lbs/min which is about equal to a GT4294, which is about the same size charger, and as such would make sense.
