What ratio?

[Terminal]

Hi in the future i plan to fit YT Rockers to my VX v6 (Non Supercharged) engine.

Now im new to the mod scene and have noticed all this took of ratios eg 1.9:1 or something like that. Now i wonder what this means and what ratio is best for what.

Any help would be greatly appreciated, thanks.

I think there is only one option for an upgrade and thats the 1.95:1 YT rollers.
Correct me if im wrong though

On the YT site i chose Holden and the 3800 ecotec and it came up with atleast 5 different ratio's.

Oh ok well there ya go, but i only ever hear of putting putting in 1.95s so it must be the most popular or most bang for ya buck, there is plenty of knowledgable v6 blokes on the forum im sure some one will come along soon and help ya out properly sorry

No worries. I read a lil on the YT site and it seems the higher the ratio the better the power gain so maybe the 1.95s are the way to go. Or the 1.9s.

Anyway anyone with knowledge i'd like some input, thanks.

1.9 is good for sure and 1.95 even more so, the YT people can advise on what if anything is needed to go with either

1.9:! is good but for VY or VZ, can't remember which?....there was some excess casting flash in the heads which can interfere with he higher ratios. Call YT for advice regarding ur model.

Won't be VZ, they are DOHC

1.9 is by far most popular (provided it's standard camshaft).
1.95 / 1.9 mixed sales are on the up though.
The casting flash problem has never been an issue with our rockers or any alloy aftermarket rockers that I have heard about. Only with re-worked factory rockers.

Cheers.
