I personally would be very happy with 13.7@100mph out of an r32 with 149rwkw.Use my website to cross check your 1/4 times with those of others to see where you could 'potentially' be. You can see that Pos #19 (flaps) did a 14.097sec @ 100.24mph with a 2.043sec 60ft. You beat his time by a solid 0.3sec whilst also doing 100mph with a 2.0 60ft time, which as you can see is quite good.
It shows that your either quicker at changing gears, have a better average/midrange power or maybe better grip.
PS. Check my sig and send in your timeslip.
