Maybe I can lend you an F3R
VORTECH V-7 YSI-TRIM SUPERCHARGER
Performance Specs
Max Speed: 65000 RPM
Max Boost: 30 PSI
Max Flow: 1600 CFM
Max Power: 1200 HP
Peak Efficiency: 78%
The equivalent in Procharger would be an F1-A or F1-C which requires a base engine hp range of 300-550.
Will it work? Yes, but I wouldn't put a YSI on a 300 cube motor or a 600 cube motor. You need to find the sweet spot for your setup. LS motor 400 - 450 cubes IMHO.
You mentioned 502 cubes. You are out of the LS family at that point that is BBC

There are quite a few setups in Australia with the YSi making in excess of 1000rwhp on Dyno Dynamics and Mainline dynos. Both of which are a lot more conservative with their numbers than a Mustang dyno
Some are even up around 1200rwhp.
So it depends how solid those stats from Vortech actually are.
They could be comparable to a Bosch 044 pump. Bosch only rate them to about 400bhp, yet certainly in the US, people would rate them at double that in terms of power a unit can support.
I guess the issue is, how fast can a YSi reliably be spun, and how efficient are they at speed ?
I can only comment on mine, and I spin to about 69k max. Even at that, the compressor blade tips at both inducer and exducer have made contact with the cover. I can only assume either heat has caused it, or a combination of heat and the blades flexing at speed
Dont think I'd want to risk spinning much harder.

Torque
From what i've been reading i'm looking for mass low end torque with the big cubes. Which i don't think you could accomblish with smaller cubes???

Tobner ran a best of 170mph @ 3300, so just simple racer math says he's making around 1200 hp to get it done-just like the rating Vortech gives it.
Dyno's can read anything they want-tuning tool and before and after is what it does best.

Either way, it would seem the YSi can blow above what Vortech claim, even if the blades do have casting flaws and bend lol
But if someone is looking for a torque monster, then a centrifugal is by far the wrong choice.

I've always heard that the Renegade guys have spun the YSi's well over the recommended ratings?
So 400-450cubes? I know there isn't a magical number, but why between those 2 cubes?

I wouldn't compare a YSI to an F2 which flows 2700CFM.

In Oz with the YSi. Mark uses them a lot, and his builds are superb.

Not sure how fast they are spinning the blower. But the smaller pulley doesnt look an smaller than 28, may even be 30T.
And I know the standard large pulley for the crank that is offered with CAPA's ortech setups is 86T, so more than likely that is what they are using. TBH there wouldnt really be much room for anything larger anyway.
I had mine custom made at 85T for this reason and currently using a
30T blower pulley.

ISIS SUCKS FAT CHOAD
The truth of this whole matter is build a 402 or 416 stroker. Why because it's the most cost effective 400+ cubic inch stroker you can build because you can use an LQ9 block. Sure you can buy a LS7 block or another factory large diaplacment aluminum block or even an RHS aluminum block or LSx cast iron block and get more then 416 cubic inches but it starts to get real expensive real quick.
