BOTTLE ROCKET

I found a lot of threads on aftermarket rockers here, but nothing specific to the new Crane "Quick lift" Gold rockers.
Does anyone have any before and after #s on the 1.7 quick lifts? The theory would seem to indicate there would be some gains, but I wouls like to hear from someone who has actally tried them.

they really aren't new. i've had the 1.8 rockers on the wife's car for almost two years. here's the dyno from the wife's car with a stock cam and stock tune with the 1.8 quick lift rockers. just to give you an idea of what gains could happen.

Hard to read the graph...what is the change with just swapping out to the 1.8's? Does the graph state around a 12-13 h.p increase? Thanks

I used the term "new" because they were listed that way at Cranes site
I was actually trying to see if anyone has used the 1.7s with any real gains to speak of. I don't really want to use the 1.8s because of the size of my cam, so I was trying to find out if the 1.7s were worth the time or money

333.4 - 316.7 = 16.7 rwhp is what it shows me.

yeah, their website development team is a little slow at updating it.

yeah, i don't have anything on 1.7 rockers, which is why i said it'll give you an idea of what the 1.7 can do.
