I need to upgrade from my BW and had my eyes on a 3532 with a divided 1.06 ar housing. Looking for mid 700hp to the wheels with as good a spool time as I can get. Getting that much hp out of that turbo would be pushing it to the limit.
The 3584 is rated for 750-1000..which is a helluva difference for a 2mm larger turbine wheel. Does anyone know if there is a difference in the compressor wheel? Im torn between which one would be best suited for my needs and spool time

I would expect 825whp out of the GTX3584RS. MAYBE 850whp if everything is optimal and at the absolute max.

Yeah, I know its good for over 700. I guess my real question is, which one is more efficient at getting to that power level

Most I have seen is a supra "ALL IN" on a GTX3584RS made 903 whp. Was on a dynojet. I would expect it to do a solid 800-820 whp on a mustang.

I recently purchased the gtx3584rs with a 1.06 A/R t4 twin scroll housing. Don't have a built motor yet but do eventually plan on maxing the turbo out

Gtx3584rs

Looks huge!

How much boost you plan on running for now?

it's a 67/68 so it's decently large. My tuner, Rob Reinen of Prayoonto Racing, said we will make up to 700 but he doesn't want to go any higher on stock block. I'm not sure how much boost it'll take to get there though

If efficiency and having the latest compressor and turbine wheel designs, wouldn't a G42-1200 Compact or G42-1200 be a better choice?

Or a Precision 6466?

Personally, I'll never own a Precision. They have far too many problems and their customer service it trash at best (personal experience).

The G42-1200 is such a large turbo that the transient response would be terrible for a street car. It's a 73/82 turbo so twin scroll t4 would amost be mandatory even for a track car. Not to mention, the G42 is just over $3,300.
