Inliners International Forums General Discussion Hi Performance Building a 302 GMC for LSR

Well it isn't theory, it can be seen on any dyno with any engine, and has been for many years. That is one of the determining factors in engine development programs that I have been involved with in the many realms of racing i've experienced. There are many benefits of increasing the R/L ratio, but the decrease in torque in the low side of the engines power band is a trade off. You just have to determine if it will benefit your needs, and not affect your performance characteristics you are seeking. He might have 1000 more RPM of usable power band on the low side of his range to gain back, and on a engine makes its peaks around 5500(I think thats what his dyno results stated), that is a pretty big lose to consider. He mentioned it was dead below 3500 RPM, so he has a relatively slim power band, if he gained another 700-1000 below 3500, his results could be much different. It would be nice to do a back to back comparison, its probably not cost effective unfortunately.
