surecam here in brisbane, he does a lot of drag cars and he is my mates dad so i got a good priceSupraPolak said:Nice, who did the custom grind cams for you? where? how much?![]()
i have no idea. i asked the tuner (who does a lot of work with the v8 supercars over here in australia). he was really impressed with the torque and midrange power, something he hasn't seen before on a turbo car. he had a v8 chevy on the same dyno after mine, it made just over 500ftlb peak torqueStu Hagen said:Ya I could never figure out the conversion on torque, maybe Ben can expain.
Klop said:...they had the tach signal reading 2 times the rpm's
That is why it looks like the RPM signal was not set up right for the dyno pull. Maybe they had set it up for a rotary. It would show 2 times the tq actual numbers.Latteboost said:I am assuming at the 5820 is RPM on the x axis. If so something is weird as the hp is much less (327 vs 620) than the torque. No matter what your HP number will always be higher than you torque number (ft-lb) above 5252 RPM.
rusty said:your dyno sheet shows about 245rwhp at the point of peak torque, which is at 3918rpm (give or take a few) which is equal to 328lb/ft or 445nm at that point. thats still real wheel torque not crank torque. the only problem from there is im not too familiar with the dynologs and what results they return. i was anticipating dyno dynamics, which return around 76% of crank power as a rear wheel figure on a manual supra, but im not sure of what dynologs will do. probably closer to a dynojet?
not sure if ive shown you this before but i made a script in php to convert between the various figures, as well as show some additional units etc.
heres a link for your figures;

the correction is based on ambient temperature, humidity and atmospheric pressure and is only 3.80%swearitsstock said:that is a HUGE sae correction
try to do it again... get a good torque reading and no SAE correction
