ok, so i have a deal on a solid axle (another post, im gettin one regardless) my question is what gear to select. the car will see mostly street and the track at LEAST once a month. in selecting a gear, u want 4th to be close to redline (or at it) when crossing the traps right? so with a few calculations ive done ive come up with...using 26" tires and slicks and a 6500rpm limiter in 4th gear
146mph with 3.55s
139mph with 3.73s
132mph with 3.90s and
126mph with 4.10s
realistically, id prolly only bring it to about 6200rpms or so so lets drop a few mph on these. the 3.55s are out cuz i dont think ill ever see 145 at the traps. 4.10s are out cuz im shotting for a high 10 in the 125mph range. im thinkin the 3.90s which are good to 130. thats a sweet trap and even when im trapping 120 thats still 5900rpms.....whatcha think??
