Default Vortech compressor maps H67B vs Si

I am looking for some help with SC selection. I am currently running a Raptor VLCB, but it's "spun out" (52,000 rpm) around 300ish whp.

I'd love to go with the Si that I can grow into but I don't know if it's too big for right now, both in terms of air flow and in terms of physical size.

Here are compressor maps:

H67B

Si
https://cdn.shopify.com/s/files/1/07...87759233695377

The H67B Looks like it would be at home at 14psi and 47,000rpm and 45 LB /minute

The Si looks like it will push the same air at around 43,000rpm.

The Si can then later go on to 22+psi and tons of air. If I can physically fit the Si, is there any reason not to use it?

Immediate goals...325ish whp, 14ish PSI
Later - ??? A 500whp build is not out of the question.

Well I went with the Si. The h67b is just too similar to the Raptor SC. Am I the first person to ever do this?
