6MT BRZ, 6AT FR-S Dyno Comparison
Tonight at COBB Tuning Plano's First Thursday meetup I met up with @carbonBLUE and @5hairpins, owners of Argento and Asphalt FR-S's respectively.
Towards the end of the night they wanted to put our cars in the dyno, myself and @carbonBLUE accepted. A far as I know this is the first time a 6AT and a 6MT have been put on the same dyno with the same environmental conditions just 20 minutes apart from each other. Thanks @Kevin@COBB for putting together such an awesome event. Here are the results: (kept you waiting ) |

Wow -- that's a bummer. I'm honestly surprised. How many pulls for each car? Intake temps?
I'd wait for some more data to confirm that big of a difference. Also, the difference might be inflated given that dyno reading is pretty low relative to dynojet numbers. Well, one more reason for boost. |

I don't have a super solid understanding of the guts of an auto. But I do know they are full of fluid, and even locked I imagine that stuff is spinning in the fluid. And friction has some exponential relation with speed. So it's not a big surprise that it holds it own at lower rpm but quickly dies past 6k. Depending on what the trans was originally from it is probably spinning faster than called for in the original design was intended (outside its design efficiency range).

Very interesting how the FRS tails off so early!
And frustrating for me to see graphically how my break in rpms are all in that valley. I spend most of my driving between 2500-4000 rpms, where torque is decreasing and hp is flat at best. Can't wait for 800 more miles and I'll finally be able to get past that valley and into the fun zone! (car is still pretty fun in that valley though) |

Actually the difference is surprisingly minimal... especially for daily driving. While 10hp sounds like a lot the difference is only between 6K...7K range. How often does one drive revving that high?
