Just not in 4th gear. ;-) And then again it will be doing lots of damage to the #2 main bearing, as well as to the pushrods, as they bow out and wear against the insides of the pushrod tubes. BTW, the FI can't do this, the injectors just can't keep up, but carbs have no such limitations. OTOH, I consider this a kind of built-in rev limiter, a bonus, since I don't care to rebuild an engine more than once. Time for a true life VW racing story: A number of years ago I had several friends at a local shop who raced a VW beetle in a local SCCA class nearby. There were always several other beetles that they could depend on to show up to compete against, including one from MoFoCo in Milwaukee. The MoFoCo bug was always tricked out in all the latest hot stuff and could be counted on to break out of the pack and come screaming down the main straight at 7-8,000 rpm. The races tended to be 25-50 miles, and as many laps. The folks I knew were pretty knowledgable and had been racing one car or another for decades; they were also the ones who turned me on to the Bill Fisher book. They had a roller crank and still kept the rpms down and the gearing up. Race after race, year after year, the MoFoCo car seldom finished a race, while the car I got to take a victory lap in won consistently, both race and season, year after year. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Too much?
