Torn on blower heads!
My A&A kit ships pretty soon and I was trying to decide between
the Vortech V-3 si or ti. The old t trim was 1200 and Si 1150 cfm's.
The ti I believe now is 1400 cfm.
I don't plan on going to bigger numbers than the 600 rwhp.
That said maybe the extra room would be still there just in case.
That may require a cam change and that I'm not doing.
Judging form the Si on my Ls3 then moving it to the Ls7.
It should be more than plenty. 7 liter no question but the Si was plenty for the ls3 which should really need less output on the LT1.
A&A recommended staying with the Si so I rest my case!

I wrestled between an Si trim and T trim on my M3, but the Si trim was so close in performance and had better low end spool as I recall. I love my Si trim on the M3 it was a no brainer upgrade from the S trim I had in the car.
