AND IT WILL HAPPEN TO YOUUU!!!
lol.
Of that I have no doubt... REALLY want a Torson T2R, but I've been hearing the scuttlebut, so.... Address that issue when it comes, if I don't have Poe build me a car instead!
Who did your 3:73 install, Dave? Or did you do it yourself? If someone else, do you recommend them? You used frpp gears, yeah? I've set pinion depth ONCE..but it never went into a working car. So I'll shell out the coin.
I've done R&P a few times, but I REALLY hate the smell of gear lube with friction modifier... like as in it makes me puke, no joke. I had Suburban Drive Line do it, but I wasn't all that happy with them. They did the install, used Royal Purple with no modifier (but...it's already in there), and when the clutches started moaning after about 70 miles, I had to go to Ford, buy the OE lube, and the modifier, and they did the swap. Clutches continued to groan. Finally got it taken car of at the dealer under a TSB. Try going to Elmhurst Auto Care, the owner runs with Council in an ex-Craftsman truck, and he knows how to do all that fun stuff the right way. Not the cheapest, but he's VERY good, and a racer, so we can kind of support "our own," if you follow.
Assuming stock trans ratios and the 275/35 tires, here's how your speeds will work out with the different gears, 3000RPM-6750RPM, except fifth is shown coming in at 4250, which is 6250 out of fourth (just for comparison), and max speed is aero limited with all gear ratios. Aero limit, for our purposes is 150mph.
.....................1.............2.............3.............4.............5
3.55...........0-43.........32-72........49-109.....64-144.....134
3.73...........0-41.........31-69........46-104.....61-138.....128
3.90...........0-39.........29-66........44-100.....59-132.....122
4.10...........0-37.........28-63........42-95.......56-125....116
I wouldn't presume to make a recommendation, but for me, it would either be 3.73 or 3.90. 4.10 is just too nuts, you'd spend more time shifting than you would anything else... Most of the tracks in our area seem to have intermediate straight speed right around 100mph, which is meat range for the 3.73, but perhaps marginal for the 3.90. If you can crack 102-103 heading into T5 at Putnam, you either short shift into fourth, then back down again in the braking zone, then right back up again heading into T6, or you whack the car into the limiter for a second or two, which can't be healthy. How would that plot out at Milwaukee Mile? I haven't driven that one yet. I would think about the tracks you run, and where the 3-4 shift comes in, and take it from there. Also think about the corners where you need to drop to second, and think if you can make up time coming out in third, where you didn't before.
