[QUOTE="ANGREY, post: 16128160, member: 188865"] It's tough because I didn't do them in a "control" type environment where it was the gears and nothing else. The E-85 made a very noticeable difference in how ready the car is to respond in mid to lower rpms. With my N-guage display, I'm running MUCH higher timing in the mid to lower rpms than before, so the car is more "woke" (hate that term) and ready and willing to lay it down. Once I put the gears on, it was even more pronounced of a feel/effect. 10% artificial torque at all rpms isn't trivial. Imagine having 35-40 more lb-ft of engine torque at 3k rpms and every range above. I did a cruise to Palm Beach cars and coffee on Sunday and was at the back of the pack and getting on I-95 I went to do a 4th gear dump and the rear got squirrely a little (just wagged, no real problem) and I was a little surprised. Also, rowing through the gears now takes on a more "traditional" cadence. Before, it was always the run up and then that extra long breath that GT350 guys learn to wait for. But now it screams through them at a rhythm I'm more accustomed to on the older 6800 limit motors. This is an expensive modification. $340 for gears and nearly $800 after parts/installation (installation kit, new pinion race, fluids, labor). Finding anyone to do a Super 8.8 for cheap is impossible. Most shops have never even done the swap. So it's not a cheap modification or something that's quick. But it is high value in terms of effect for $ spent. If I'd have known then what I know now, I'd have probably done the gears before I did a lot of other stuff. [/QUOTE]
