Does anyone have the green slide horsepower/Torque - RPM graph? Thanks!!

Thanks, do you have torque numbers too?

Jason, if your track utilizes the green slide I have at least a half dozen brand new ones in stock that I'll sell for $5.00 ea.

going to assume this is 206, because i don't know what a green slide is... assume the carb slide... not knowing what i'm looking at... is it safe to assume that the best torque rage would be used for coming off the corneer 3500 rpm to 4300 about... and the HP then pulls you down the straight between 4100 and 5300... then back into the corner?? looking for an education here...

Hard to believe that those are from the same engine. If you graph them out, they're totally different. Actually by quite a bit.

Engines do not make horsepower, they make torque, then we calculate the horsepower. RPM X torque/5252.1 = HP Torque is a measurement of work, HP is the speed at which you create the work.

What you said is what I call one of karting's self evident truths. Torque off the corners, horsepower down the straight.

Forever- Assumption is correct, a 206. Performance numbers are from Briggs, the motor was fitted with a green slide that is measurably longer than the stock black slide. The motor makes its best torque on the bottom end of the rpm curve, so gear choices & clutch engagement are "test items" that need to be understood by each driver/team. Tracks are rarely the same, meaning it is nearly impossible to guess on this forum exactly what ratio is best for THAT track. Testing is huge! There's a trade-off for 206 racers, needing to understand which track (and class) requires more/less time on the rev-limiter. Some will spend time on the limiter (2-3 seconds) and others, not at all. That's the beauty of racing, personal preference gained though experimenting, and seeing betterment. Heck, two guys can run the same track, identical times, at the same weights, with different gearing! Lower HP racing involves so much more than motor, much like Daytona or Talladega. The driver's feel, understanding of set-up, and strategy is huge. Have fun with it!
