Dear Builders: Please have patience with me, and hold the flames till I'm done... I seem to recall that a VW magazine this spring did an article on high lift rocker arms (maybe Fast German's?) on a modified Bug motor. The before and after dyno tests showed a maximum improvement of about nine HP at about 4500 RPM (I think). My recollection of details is sketchy because I wanted to buy the rockers for my Westy but became disillusioned by the test results and

discarded the article. Anyway, did anyone else read that article and can

confirm my numbers? I realize a waterboxer is not a bug motor, but aren't they similar enough to draw a comparison (My ignorance of cam profiles, valve sizes, cylinder displacement etc. of the two motors not withstanding)? Are not the performance rocker arms the same? Forgive me for asking questions without knowing all the facts, but bottom line; is 9HP gain on one test versus 22HP on another using similar(?) motors reasonable, or am I all wet?

If you look at the chart, adding the rockers "ONLY" added 22 HORSEPOWER at the wheels... (90HP + 22HP= 112HP A 25% increase in power on a STOCK engine)...

Imagine the HP AFTER COMBINED with ALL the other mods I made...

SO, adding 45% might NOT BE SO HARD after all folks...Plus with no additional stress only reduced stress on engine...

Heads Cam Exhaust Crankshaft Flywheel Fuel pressure regulator Lightened valve train Ratio rockers Use of synthetic oils Friction reducing coatings Throttle body Match porting intake and exhaust Air filter changes Blueprinting parts Adjusted timing Plus CAREFUL assembly...

A lot of little changes add up to a bigger change.
