Anyone heard of Hotrocker Variable Rocker Arm??

[MES]

I ran across this web site today. They claim to have a rocker arm that varies the ratio depending on the engine RPM. Seems like a good idea if your going to put an aggressive cam in a car but want to maintain low RPM drivability. Their web site states they will have one for the Viper V-10 this winter. I wonder if it's going to be reliable and provide any real gains. Just wondering, it sounds like a good idea.

Sounds interesting, but I'd rather not be the first to test it

I guess the real question is what are the HP gains going from 1.5 to 1.7?

If I were going to put a large cam in, I wouldn't test it on my car without some reliablity questions answered. I would however use Rhoads lifters. I have always used them in my other cars without any problems and they work great. I just don't know if they can be made for the V-10.
