I have been watching this thread in the product review and man why it hasn't come around sooner or became standard equpment in an engine is beyond me.

It could really free up the power in the hi R's in our 60 degree's.

By the number the 2.8 is a possiable 14000 rpm engine.

Even so if one could build it right with a rev kit I bet 7-8000 could be possiable all day long in one of our V6's.

Warning the thread is full of BS , bitchin n moaning but only from those without the minds eye to see the light.


AFR hydra-rev Kit: Good or Bad?

I think the pic explains all. What a great idea.

If you bought a roller cam and had one made it would be benificial but it isnt a must unless you wind up really high. The costs to use that in a 60 v6 would be high because you would only place that on a engine built with the very best components. Ridgeway makes a stud girdle for the 2.8 , 3.1 and 3.4 with Iron heads , the crane gold roller rockers and a roller cam and good rods and you would not need a hydra rev.

If Buick v6's can go 6 seconds in the quarter without a hydrarev, do we really need to consider such a device as this as anything other than a trick piece not required.

There have been alot of 60 degree v6's operating in the 8000 rpm range with solid roller cams , from midgets to score class 7 baja.

I would strongly advise using a better block for a rollercam. The GMPP sells a better block, mainly for racing, for $3K, but weighs in about 80 pounds (aluminum) and has better oiling facilities.

Engine internals is not my area of expertise (do I have one?), but reading between all the bs in that post, it seems like if you want to really build your 2.8, and you've got the money to do it, it's a worthwhile investment. It makes sense to me even though I have yet to tear down my engine at all. And I went to the hydra rev web site, and it seems they make one for the 6.

SO how about a breakdown, on how the 'rev kit' works?

And might I point out - without the proper cam/heads/intake/exhaust to actually flow the air you'd be pulling at 7k+ rpm, you're doing nothing but making noise.

Ha, I don't think most people are serious enough to even want to afford a 3k engine block even though its probably the best 60 degree block you can get.
