That an extreme scenario in my opinion. like tech says thats an 11 second car that can cruise to the track.If it spends a lot of time on the track,then buy a trailer for race days,long walk home if something breaks
I know all about this, at first I used a well built 700r4 with it's 3.06 first gear and a set of 4.10 gears which comes out to a drive ratio of 12.55, if you compair this to a th350 and it's 2.52 first gear it would be the same as running a 4.95-5.00 rear gear with a th350, then the 700r4 has a 1.63 second gear which is about the equivilent of running a th350 (1.52 2nd) with a 4.56 rear gear.
this was all in a high 11 sec car, I enjoyed the o/d if I was driving on the highway (which was rare) but I didnt enjoy trying to make it hook. My 60ft times were too inconsistant because I had the hardest time finding that happy medium on take off. Not to mention that 1st gear felt like a "granny" gear. I have since swaped out to a th350 and now have 4.56 rear gears.
