I should not have said that the HFS is not recommended for CIS as that is not correct. It would be more accurate to say that it is recommended for highly modified engines.

If you really want to split hairs the HFS was designed as a big power replacement for the 965. It is capable of supporting 525+HP and 1.2+bar at 7000rpm. That is EFI territory.

The HF2 is a monster. Recommended for EFI engines capable of 600+HP.
