The below is dyno for tuned Q50/Q60 vs stock GSF(467hp)
Actually the best part of this new VR engine is its Torque, not HP!!! Look at how good its torque on low rpm...
HP is good for racing but torque is good for daily spirited or mountain driving!!! I don't do street racing or track... So, high HP is not so important for me... (except my personal 0-96 testing)
This old GT-R dyno... In my opinion, tuned Q50/60 should feels faster on street but new stock GT-R is still slightly faster or equally fast on track thanks to high HP...
For 0-96 GT-R is fast is because it has launch control. Without launch control GT-R is not so fast and takes about 4 seconds... Stock GSF or RS400 takes about 4.5 seconds...
