Twin Cam Dyno Results

[europa88]

Here is a better image. My car is still making power at 7000 RPM and I think could make more at higher rpm if I could rev it safely. But with the original cast crank I would be crazy to try. I think it would make a few more BHP up to about 7300RPM then fall away. It would appear that your engine makes its peak lower down! Impressive though for a Stromberg head!

I think if your af ratio was a little leaner (around 12.5:1), you would make more power.  The dip in torque between 3500 and 5500 is probably due to the rich mixture (from accel pump?).  That is what I found on the dyno since its easy to adjust the af ratio on my Hitachi SU carbs.

Anyway, the big intake valve you have should give you plenty of power and high end capability.

Thanks for posting.  I think it is really great when people post their results so all of us can learn from it.

Here are my engine Dyno results from the spring of 2021.  10.1 compression, steel crank from formula Ford, Crane/FAST electronic ignition, stainless header, Mikuni carbs, approx. 1700CCs.  I believe this was done with no pully on the cam, and no muffler.

Looks good
