Autocross and a 904 transmission

If yur gonna run in Second gear with 3.55s; realize that the car is geared about 16 mph per 1000 rpm @zero slip.
at WOT, that makes about 14.4mph, and so
2000rpm = 28.8mph, 3000= 43.2, 4000= 57.6 and 5000=72
And you have a "stock stall".
Ima thinking; SOMETHING has to go.
Either the 3.55s, or
Second gear; or
the stock convertor.
But I'm not an organized event, auto-crosser, lol.
