Re: What did you do to your Crossfire today?
Yes but you didn't factor in the engine torque peak. 229 lb-ft for the XF, 140 lb-ft for the Miata. BIG difference. Also less than full throttle and first tends to surge (have reset the throttle).
I suspect the trans was developed for the short stroke 4 cyl models like the 230SLK that have little low end grunt and just kept the trans rather than develop a new gearset for the 3.2 six. Also Chrysler uses the same manual trans in the Jeep Wrangler with does need to go straight up the side of a wall slowly and having the same gearset simplifies logistics..
And I guess I should have said 25+ since pushing that hard in 1st I am not looking at the speedo & Torque only monitors at ODB rate (~once per second).
Don't get me wrong, I *like* Traction Control particularly in Florida deluges and my usuall response except in slow traffic, malls, and my driveway is to just start in second and will say the 2-3 shift is good and the 3-4 is great, friends say it sounds like an automagic (though is strange: when road racing I used to shift relatively slowly to avoid upsetting the rear end since rarely going in a straight line. Autocrossing now...)
Not the first time. My '78 Sunbird with SBC and "Muncie" had a 2.98 low and 3.08 axle and first was just pure wheelspin through a posi, I used to start in second (and often wished for a fifth but a B-W T85 wasn't rated for a V8). Later I used a 2.79 axle on the street that was better but not great (Vega axles were $25 for the whole thing and would last a few months & why I'd like a 2.60-2.80 for the XF.
