I noticed on x-ph.com that "with only an air filter, JB4, and 93 octane / meth we made 481.18whp and 437.84 ft/lbs" with the pure stage 1 turbo for bmw b58.

Would similar results be possible with a stage 2 hpfp and 93oct no p.i or meth?

Would a Vargas gc turbo have similar results (asking bc i would then not need a core exchange)?

This Stage 1 dyno is from like 2017 - 2018. Newer Pure 800 cast doesn’t have a core charge. And yes, Pure 800 or Vargas GC will easily make 480 whp on 93.

So either pure 800 or gc with dp,charge pipe, and heat exchanger should do the trick i take it?

Pure800 Cast or DAW FlowMax 2.5 is what you're after. Skip the charge pipe. Will also need a HPFP. For 93, can probably just stick with TU.

What’s wrong with the gc

It's just compressor side only upgrade. And putting the P800 and Vargas GC in the same sentence doesn't really make sense. 2 different price points, 2 different power capabilities. P800 and Daw FlowMax are equivalent. P800/DAW will spool like stock but offer much more headroom.

Oh okay

On your graph it says 480whp on 93+meth. If I do a hpfp instead of meth would I potentially get similar results

They're running into octane limits on the relatively small size of the turbine/compressor wheel. Meth adds octane and decreases IATs, no amount of additional 93 (as in adding a HPFP) is going to make a comparable bump in power relative to increasing the knock threshold (increasing octane). If you want to hit similar power, you're going to need a bigger turbine (to decrease EGTs and IATs).

So maybe like a DAW flow max or pure 800

Exactly.

So we thinking either of those,dp,tu pump on 93oct will do the trick
