Find a more realistic dynamometer.If you want more go why not simply buy an 8V?Pete
Find a more realistic dynamometer.
Hmmm..how do you know any dyno is accurate? If it's a Dynojet the power readout will be 5-10 % more than a eddy current dyno like a Superflow or Mustang....
the OP is doing back to back comparisons so that's fine.
Has anyone carried out an increase in bore? If so which pistons?My other thought was to remove the airbox completely and fit 'pod' style air filters on the inlets to the injectors. My concern there is the affect on the bottom/ mid range performance of the engine.
If you run all your dyno tests on the same machine, you'll be able to know what the gains are.
Yes for sure...but the original comments were that the HP reported by the OP were exaggerated ....I was referring to that...
Find a more realistic dynamometer.Where did the map come from? Is the Lambda still active? You won't be able to take the bores out much larger without risking not having enough meat around the suds.If you want more go why not simply buy an 8V?Pete
Hi Guys,Over the past 5 years, I've had a re map, heads skimmed by 25 thou', free flow air filter combined with taking the cover off the air box to increase the performance on my Griso 1100.The result so far has increased the back wheel out put from 83 BHP to 95. Measured on the same rolling road for consistency.The torque has been increased as well ( don't have the figures to hand).I'm considering gas flowing the heads along with increasing the capacity ( the aim is to achieve atleast 100BHP at the back wheel)There is plenty of info/ companies who can gas flow the heads in the UK, but finding consistent info on whether the capacity can be increased and by how much is not available over here.Has anyone carried out an increase in bore? If so which pistons?My other thought was to remove the airbox completely and fit 'pod' style air filters on the inlets to the injectors. My concern there is the affect on the bottom/ mid range performance of the engine. Any info would be useful.Thanks.James.
Nope. For some reason or another, many Guzzi owners tend to lose their minds to various extents in either over or under thinking what the Moto Guzzi big block is capable of. I have been subject to this at various times until reason thankfully prevailed and I realized that most Guzzi big blocks made over the last 30 years are tuned to within an inch of long, reliable lives. Name one two valve pushrod car engine in a production car that is redlined at 8000 rpm, and which cranks out 80 to 90 wheel horsepower per liter. Doesn't exist.
This is nonsense. A stock Griso 1100 makes 70 hp per liter, not "80 to 90," * Calculation: 74.19 tested * (1000/1064) = 69.73 hp per liter.
