Question about 1999 Moto Guzzi Sport 1100 i
Serious porting 96 or 97mm pistons 382 cams 12-1 or so compression etc. So far I have been told by a few people that 110-115rwhp is pretty much unattainable(always followed by some giggling and snickering in the background). From my experiences with other motors and based on rpm, valve sizes etc. that should not even be an issue, but then again these were completely different motors. What then would be an attainable goal?,Yes, there are always companies who will promise heaps of HP. What is never mentioned is reliability or service intervals. If you want 'Race Bike' performance you can have it, but about 100RWHP is all you are realistically likely to get from any 2 valve Guzzi engine and I don't give a toss what anybody else claims. Also using the biggest valves is NOT always the best way to get ueable HP, nor is the stupidest cam with ridiculous timing. There are many, MANY issues other than valve size that contribute to gas flow. There are also many, many things that will effect how well, or not, a cam will work. At the end of the day you are looking at a 12 year old motorbike based on a 40 year old engine platform. If you want more performance go and spend money on suspension and to a lesser degree brakes. A *good* 1100 Sport will produce in the mid eighties HP. If that isn't enough? Go buy an R6 or even a Griso 1200. If you want to play at extracting HP from a Guzzi 2V motor that's fine, but if that is the case why ask what people have done before? Use your own ideas and then compare them to previous efforts,,,
