Default 408ci/TH400 Dyno Graph




Don't mind the Flywheel at the top. Its RWHP on a DYNAPACK.

Where would you guys shift by looking at this graph?
Mind you its a RMVB TH400.

I'm not sure why it stop so early to be honest. My rev limit is set @ 7000.
How much more Hp do you think it coulda got if we kept going to 68 6900?

The dynapack is not realy usefull to meassure for power on an unlocked convertor car. The majority of the tuning was done on the street. I just make a few pulls to see what it does with what it can.

The Dynapack reads hub RPM, so when a car has a convertor that does not lock, then the engine can rev to 6500 while the hubs are only seeing 5500. Get what I am saying? The axle is going slower due to the convertor. When I measure the AFR, I just watch the wideband and my laptop only, that way I see what is realy happening. Its just for show in this case.
