[QUOTE="biminiLX, post: 15710224, member: 7795"] Any reason you say 3.73s and not 4.10s? If you don't plan on adding crazy power, the 4.10s a better all around combo IMO. I had both when I just had bolt ons at 750rwhp range and these cars dyno with peaks at 6600rpm range. 3.73s had me trapping at low 6100rpm range and 4.10s where closer to 6500rpm. It trapped higher with 4.10s and was better around town off boost. Only way 4.10s are too much is if you want to have 800+rwhp and don't do cams/built lower end. I now have 960rwhp and still 4.10s but cams and built motor so I want to trap at 7000+ but I'm prob ready to drop down to 3.73/3.90, just need to see what the ET Street R 28x11.5x17s do on datalog. Bias plys like your Hoosiers will grow, do you remember the trap RPM you saw? Sounds like you have the right plans to improve next outing, probably gears, control arms, MGW shifter. How do you like the N2MB bow? Mine is installed but I haven't played with it much, I really want the consistency of 2-step launching and WOT shifting should help too. Keep us posted. -J [/QUOTE]
