far out, the turbo's are gonna enjoy the cooler weather.....

Will there be runs at night or only during the day?

I take it will only be during the day.

I still haven't really used the 4K Sony Action Cam I got in 2015, so it's going to get a work out and a half this weekend.

Checked a few of the HUB dyno printouts and most contain similar discrepancies.  

Unless you have clutch slip (which you haven't) then the RPM is clearly wrong.

This could be an issue for Mainline's Derived Torque calculation as presented on your graph. The hub will measure TrqT which is then divided by the final drive ratio to get dTrq.  For example my car makes 3081.8 TrqT.

So 3081.8 / 3.73 = 826.22 dTrq

If we used a final drive ratio of 3.62 (5440/1500 as per your graph) then the resulting dTrq would be 851.3nm. That's a fair way off 826!!

If it's an auto car you would expect slightly different ratios as even on a locked convertor you tend to see 30-40rpm slip....but not manual.

Anyway, I question the Mainline's calculation if it's using a generic SAE PID for RPM pickup....definitely not going to give you an accurate dTrq figure.

Power is not not affected as that's calculated from TrqT and SpdL(or R)...I.e. axle rpm.

To technical for me.  I don't care.  Car has plenty of fuel pressure and isn't running lean.  So I am happy.  

 

Car was only put on the dyno to check fuel system.

mmm I just wana go down for a pie and a passionfruit slice from the mt barker bakery.

 

and stay for the racewars

[eff xr6t]

The rpm nazi himself even has inaccurate rpm haha

Oh the farhking irony
