Dyno Graphs

HP=(Torque)X(RPM)/5252
This means that on ALL torque/horsepower curves that use HORSEPOWER and FT-LBS (instead of Newton Meters), the numbers will be EQUAL. its because of math. where the graph crosses has no meaning whatsoever. The numbers ARE equal at 5252 rpm (because when you plug that into the above equation, 5252/5252 = 1, so HP=Torque).
And just because the lines physically cross at 6000 or so rpm means nothing. the scaling is different. and there is NO industry standard on scaling, but there IS an industry standard on that above equation.

here's mine: https://www.rx7club.com/time-slips-dyno-121/my-first-dyno-wohoo-d-444016/
315/246 @ 13.5 psi getting slightly lean at the high end
250/188 @ 8 psi solid afr
one question, how does SAE correction work?
I think the torque in my graphs is uncorrected but the hp is SAE corrected, I plotted the torque graph in excell and used hp=tq*rpm/5252 formula to get the hp graph and it was lower than what the dyno graph says.
If I go the other way and plot hp but calculate tq then I get a higher torque...

drift,grip,drag
I just saw an article at my doctors office about an FD hitting nines on street tires and 25-28 lbs a boost. I dunno know fer sure cause it was in a crazy magazine from europe.

Nah, both the torque and spool doesn't seem like 20B at the boost level.
Good job on the tune nonetheless!!

no sounds about right...stock puts out 215-218 usually so you made an \"honest\" 20 hp with exhaust not bad. by honest i mean you didnt have to increase the boost to make the horsepower
#100
I didn't touch anything on the car, just make an 3 inch exaust. The boost is 10 psi, the air fuel is 12 and the engine and everithing else is stock. This summer I will install an Emanage for increase the boost at 15 psi and that will be the last mod than I will do....the torque on the wheel is 220 pound flat curve between 3000 to 6000.
