100bhp or 100rwhp both very possible although the first comes much easier. So to answer the question. Yes 100hp is possible and cant be made any other way than the basics. Cam, compression, carbs, exhaust + headwork.

The argument on the 200bhp A-series. I believe it. The dyno sheet showed it and i really cant see why vixen and bert would lie about it. What would they gain. Absolutally nothing. Im sure mush more could be had from this engine. A high horsepower figure, especially in small motors usually means a preaky torque/power curve which in turn to be benefitted from needs suitable gearing. You dont see formula 1 drop back almost out of the power curve each time. Same with v8 supercars. 500rpm drop per gear keeping it where it counts. Berts car still has street gearbox ratios with street diff ratios making for a not overly exciting gearchanges. Each gear i assume would be almost if not out of the power band just about. With fine tuning of ratios in particular im sure it would be a very quick car.

And not to get too involved but Harry are you not in the 1600-2000cc class yet comparing your times to the under 1600cc class. Seems hardly fair and although your saying it should be quicker torque of the L im sure would be greater even with less HP. In my opinion its hardly a fair comparrison. Torque is easier to tune than horsepower for the amature. Most highly competitive forms of racing use horsepower yet they have the ability and mainly $$$ to do endless testing on ratios and what not to make the power useable.

The GREAT DEBATE, 200BHP or NOT? WHY NOT?
