I was going to use the Pauter roller rocker arms
(ratio of 1.5:1) but decided to sell them since the money in my pocket would be better right now than the money in my motor (IMG:style_emoticons/default/smile.gif) 1)I thought I read that the stock /4 arm are supposed to be 1.3:1..is this correct? 2)How often are they the correct ratio? 3)What is the biggest difference has anyone seen? 4)Would the /4 benifit from using different ratio arms on the intake and exhaust (example: stock ratio on intake, 1.5 ratio on exhaust)? 5)What improvements can be made to the stock arms? 6)Is there an interest in modified/blueprinted stock arms? 7)Is there an interest in non-stock ratio stock type arms? 8)Pauter already offers 1.5:1 aluminum arms, but is there a market for different ratio aluminum arms? |

1/ 1.3:1
3/ VW was good at getting the ratio correct 4/ 2 different ratio's would need a custom cam, not worth it IMHO. 5/ You can lighten them a bit and if your anal you can balance them all the same. 6/ little, see above 7&8/ you must have cams made for different ratio's, forged Cr-Mo would be much better, I'm not crazy about aluminum rockers and rollers have the heavy part right where you don't want it, over the valve. |
