FE Torque Curve

Nice dyno chart Barry, what cam specs were used for that one???

138° water temp makes for some good horsepower numbers.... I bet the oil was nice and hot too.

I'm trying to find the dyno sheet of the 482 I did that made 636 lb-ft....or the sheet for the Boss 529 that had 700.

If you ever get the chance you are welcome to bring one of your engines up here to dyno and compare to your local guy. Free (you buy gas and lunch). It would be good data for all of us to have.

Having done the EMC deal for a few years I know that many dyno installations give different numbers, and that it has nothing to do with the intentions of the builder or operator - but more to do with room venting, exhaust layout, and physical hookups. I've compared mine to several local pumps, as well as the ones at the contest in Ohio - but more info is always good for everybody.

I'm looking at my last dyno session and all the pulls started at 3500 rpms.....That part I understand,looking the water temp,it stayed between 145 and 150......
looking at your dyno sheet,your water temp was in the 138 to 145 range,any particular reason for these water temps vs. running the water temp at 180 degrees,more closely to the "normal" operating water temp.???
Just curious.....

I normally run the pulls at around 160 water and oil. Its really a habit from the EMC rulebook, where the 160s are the required minimums and I set the thermostat on the cooling tower to that level. The water cools pretty fast when the engine's off - I have 1500 gallons in a vertical tank behind the back wall. Normally I'll run it for a while under moderate loads to build temp. On this particular pull I was re-lighting it after checking valve adjustments & plugs and realized that I was getting darn low on gas - so I just smacked it as soon as I felt comfortable enough. I happened to have it nearby to scan 'cuz it was the last one of the evening...

Brett can confirm seeing some Hollywood numbers on some sites where water was at 110 or less...
