    Dyno Graph - Real Wheel Horsepower

    Going beyond the dyno graph...Spend enough time comparing dyno sheets and you will begin to wonder why so little information is normally considered enough. In the real world, most numbers come with additional data, data that is necessary to make a full decision. For example, if we said "John has been on a diet for six months and hasn't lost any weight at all," you might assume that his diet is terrible. Of course, if we continued by saying, "but he gained 15 pounds of muscle mass, can now bench three times his body weight, and finished a half-marathon on his first try," you would get the full picture, proof that John's diet and exercise plan was working well. The same can be said for the dyno. For instance, if we said, "Installing the new intake manifold and cylinder heads only picked up five rear wheel horsepower," the natural reaction would be to think they weren't worth the money. Completing that sentence with, "however, looking at the datalogs showed a 3-psi drop in overall boost, a 35-degree drop in incoming air temperature and a slightly lean condition throughout the run," we would know that the new combination was actually much more efficient and capable of making significantly more power, assuming we could get the missing boost back and add enough fuel in the tune up to compensate for the increased airflow. You see, you can't ever go off horsepower and torque alone, they just don't tell enough of the story, which is why looking at and understanding datalogs is essential..

    Paint it whatever way you like. I did.

    Black for the intake and used Navy Blue/Red for the lettering

    I. Going to do it. I already spoke with my local tranny shop and with Gear Vendors. You buy a crossmember mounted torque arm, which is an improvement

    Hydraulic slave cylinder

    Does anyone know where I can obtain an adapter for the clutch actuator for a 2000 Camaro V8 to adapt an AN line to the stock GM fitting?

    I just purchased a used FAST 90mm intake today. I will port out the inlet to 92mm and then port the runners. I'm also going to paint it. Not sure if

    Right on. I'm hoping to push somewhere around there when I'm "done" with mine. I'm also thinking about doing a FAST 92mm.
