there are some threads over at MD on them. they seemed to work well on boosted stuff but that is kind of a given as you usually need ignition upgrades at a certain level of boost.

I think they claimed around 8hp on a stock car. even if that is exactly true (which may or may not be true) it is not exactly a cheap mod for 8hp without getting into the quality of there products or anything like that.

I personally would not really consider them tell 10psi or so and even then I would research them vs the boost a spark and all that which I have not done yet. I think it was white99gt or someone like that that put them on with the KB 2.2L and was initially satisfied.

yeah thats a lot of money for something that prolly will not give you more than 10 hp at the most n/a.

and going with what is said above when your boosted you are going to need to get into the ignition system and i bet kenne bell boost a spark works better.

GMS FTW!!! Hahahahahahahaha!

Most people will tell you Granatelli motorsports is junk, and what they are telling you is true. Never ever consider buying another one of their products again, are we CLEAR?
