Nice, looking forward to the comparison!

Really similar numbers on my 2013 as well. Owned for 9y/48k miles, 40+ track days, lot of canyon drives, and... 6 coils :brokenheart:

Using e85 also seems to make the issue worse, especially in track conditions.




Iím also curious to know how much of a difference the 2017 coilpacks make.

As I said earlier, 15% is just an estimate of drivetrain loss that just happens to work reasonably well for various RWD cars in this class on most dynojets (1st gen FR-S, S2000, E36 M3, etc.) ...

I don’t think it works that way. Theoretically the more power you make, you should have more parasitic losses (even assuming everything else stays the same) due to greater loads, deflection, heat,...

Yeah I think there is a notable low/midrange torque advantage with the gr86 and thatís reflected in the way it pulled the ap2 off the line in the SG drag race.

Yeah the comparison with the original FR-S, ND2 Miata softtop, AP1 and AP2 S2000 are interesting. You can see the gen 2 basically leaps the field (although added around 138 lbs according to CD).

In my testing, the gold foil didn't do anything. It might have actually shortened the life of the coil (only lasted 2,022 miles with the foil).

Driver skill, willingness to push, and tires. Have to equalize those to make any kind of real comparison. But yeah I’d expect once those are factored in the m2c would be much faster.

If that ends up being true, that will probably be enough for me to go with a GR86 premium. If not, likely a BRZ base trim (confusingly named premium as well).
