I always wonder why people ask how far they can rev to, just seems to be for the sake of it? Once the power is dropping off then its revved far enough as long as when you change gear you are back on full boost.

We used 9900 rpm rev limiter for whole season. So btdt.

Need valve springs with over 40kg seat pressure and 125kg full open.

Need cams over 250deg from 1 to 1mm.

Need lift as much as You can do, enough for the lobe to hit the head without milling.

Stock crank is fine, just make sure it is in balance and straight.

Need dry sump and lot of oil pressure.

Need racing tappets. Modded from oe won't do.

And yes, need big hotside.
