Bill Sherwood you are assuming off-road and circuit racing are the same in terms of motor requrements.In off-road bottom end is critical to come out of very slow corners and this why flat 4's and 6's were so sucessful for so long.I know that people have made over 200 hp with 16 valves but you have to rev them hard and they have no bottom end.The same applies to 20 valves-if you want over 185 hp people disconnect the VVT and put in huge cams.The result-no bottom end. The other point is most cars in the 1650 class run VW transaxles and a stock 20 valve is on the limit for these boxes.We have also found high revs is more of a drama than horsepower. The bottom line is that 20 valves have dominated in class 2 against all comers regardless of make or budget. The only people who claim the 16 valve is better for off-road haven,t used a 20 valve and choose to ignore the results. Also when 20 valves came onto the scene, well worked 16 valves were getting flogged by standard 20 valves. Everything I have stated is from results in off-road racing- not on a dyno or a flow bench or on bitumen in a formula atlantic race car. Results talk- bullshit walks and the weapon of choice for off-road racing in the 1650cc class is the mighty 20 valve Toyota. [Report message to a moderator]
