[IHI]

I understand the principal with revs, but with the little to no lag time with a properly built turbo it seems like overkill. You can only put so much pressure into a block before you start to have blow out problems so with both systems I'd think boost levels would have to be kept low and in check to make it viable.

But there are soo many trick gadgets on the scene I'm sure they have blow off valves that can cycle with each other to come up with a good tradeoff.
