The Hellephant can’t really be compared to a Redeye motor... There is more separating the HE from the RE than the RE from a HC.
The 3.0L blower, aluminum block, hand built, etc... if you were even considering the Hellephant motor, the $30k doesn’t scare you. In the scheme of things, I think it’s worth $10k on top of an RE motor for cool factor, oh, and then all of the actual parts that make it special.
If you want to save money just don’t do anything... lol
