The Whiplash cam just moves the intake and exhaust lobes closer together (smaller LSA) and thus closes the intake a bit earlier and helps cylinder pressures... a bit. But the cost is a big overlap time and that hurts low RPM performance with a lot of intake charge going down the exhaust and a lot of intake reversion that dilutes the charge.. bottom line is that the low RPM performance will be worse that what you can achieve. It falls into the category of a poor substitute for real compression ratio. All in all, not anywhere near as effective as the standard methods of raising compression in milling heads and/or block.
