I suspect this dyno is from an automatic with a decent torque converter stall and one from a manual would be a more direct comparison to eliminate the benefits of auto vs. manual from just the engine to engine comparison.


We run stock L36 converters. The SC motors blow through them a bit and it gets it a bit more stall than normal (K factor), so its nothing too fancy.

I can easily say that low in 2nd gear the ~380whp manual trans 3800 i built with a really "bad for low end" cam was more than a handful at 2500 rpms.

You may run stock converters on your builds, but the car from the dyno graph you shared had an ATI 3600 rpm stall.

Some could say my car is a handful at 2500 rpm in 2nd gear as well, so lets see the dyno from your 380whp manual trans car to see how different they are at 2500 rpm.
