Still didn't get to the dyno yet. I did, however, replace the drilled slides with another set of stock slides (2.5mm air port); the only change on the replacement slides is a light polish job by hand. The polished stock slides perform about the same as the drilled & contoured slides. The bottom line is I'm not sure it's worth drilling the transfer ports in the slides.
I might swap them back & forth a bit & see how it does.
I also want to try NBAD needles (that's 790 BA/SM for you, Stacka
) & see how they do.
