Ray,
tom here from the ITB race at mid-ohio. i was beside you or the other audi at the 2007 IT Fest. my crx was the one with the flame job in the pits...
those are some interesting numbers for the HP vs. TQ compared to other cars. one thing that bothers me about OEM hp numbers is that some de-rate to meet certain govt. restrictions and others seem to have smaller horses because they want to look more powerful. these number do get manipulated somewhat.
what i find interesting in your numbers is the HP per CC and TQ per cc. here is the comparison of yours to mine (i am 91 hp and 93 TQ, btw).
audi: 4.94 HP per 100 cc (110hp 2226 cc)
crx: 6.12 HP per 100 cc (91 hp 1488 cc)
audi: 5.48 TQ per 100 cc (122 TQ (okay, ft-#'s, etc.))
crx: 6.25 TQ per 100 cc (93 TQ)
on the face of it, i would think that your car could gain quite a bit since it is starting with such a large motor. now some of this no doubt due to mine having 3 valves per cylinder vs. the two you have.
however, when looking at weight per motor size, my car as classed is 1.43 #'s per cc vs. yours is 1.14 #'s per cc.
i have said that the TQ is a bit of a red herring because most of the numbers i had seen were not that much different in the TQ to HP ratios. but mine is 1.02 and yours is 1.11.
not trying to start an argument, just trying to understand how the classing was applied to the two cars.
hope to see you on the grid this next year at mid-ohio. but hopefully out the driver's window instead of ahead of me on the grid and out the passenger window!
good luck. i hope the general requests being to get to the process weights within a 5# window instead of a 100 # window are good to you.
