Coming Soon: Higher Ratio Rockers

[bszopi]

Here is the official press release from Scorpion about the release of the rockers: New 60-degree V6 Rockers Have New Technology

[Nick-G]

I'm still in the process of learning this stuff my self so someone correct me if i'm wrong but isn't the ratio changed by moving the fulcrum of the rocker either towards the valve side of the rocker to lower the ratio then towards the pushrod side to raise it?

As far as duration i'm clueless.

[Lilchief]

So how does the ratio change ? The store says from 1.5-1 to 2-1. Do they change with speed and how is that done ? Or are they somehow altered to change the ratio ? It also states that the duration changes at higher rpm. Just need some enlightenment. The initial price is a real bargain.

[Nick-G]

With all due respect, THAT doesn't even come close to answering the questions I have, and I suppose others on these.

Pushrod requirements?

And this whole "what the hell ratio are they?" question.

I'm the first to admit I am an idiot with some of this, but DAMN IT, 'splain it in language your Grandpa can understand.

And I will buy them!

Don't quote me on this but their should be no need for different length pushrods.

These are made to be bolt on ready to go. They will come with the pedestals. AND bolt. They of course from there will be non adjustable, unless you ca find an adapter stud that will work. NO grinding will be needed at all.

[montess408]

will the intake manifolds need to be machined like it did for the crane gold rockers??

[alerored04]

I put the same question in the other thread as well.

[asylummotorsports]

I have to admit, I am a little confused by some of the description.

And what is this pre-order pricing thing all about? $148.46???

I know I must of read this wrong, however if that IS the price per set, put me down to pre-pay for 4 sets.

EDIT: I just tried to order a set and it came up $299.00.

Still good, but I would appreciate some more info on this.

Thanx

lift is adjustable from 1.5-2.0? and this thing of changine duration through the rocker...how's that all work? these babies are sweet ass!! totall worth the $300 over the Crane golds!

[kwhauck]

sorry, they are available for pre-order in the wot-tech store.....

[gectek]

not so fast.....

[kwhauck]

they are done, check the wot-tech store.....

[alerored04]

/\ Works for me. Whoever is keeping track of this I will be ordering a mixed set when they are available!

it's 1.8 intake, 1.7 exhaust. that's what Ben has recommended. others have said to leave the 1.6 on the exhaust. i find it hard to do that. it has something to do with thermodynamic efficiency. the exhaust needs to stay at a certain temp. more exhaust lift will lower the exhaust temps, thus losing power. though, i grew up with carburetors and distributors, so what rules applied then, seem to no longer be the rules of today. it's amazing what an LS1 455 can put out today!!!
