IMSA Milanos Vs Grp.A 75s

["Julian Brattoni" <alfa_power@domain.elided>]

All shots I have seen of US IMSA cars (at Road Atlanta etc. and maybe even 
Sebring?) have had the large kit on it that was released on Euro Spec 
tourers with the 1.8T motor- and I havent seen any with the factory released 
bolt on guards from the TS and 3.0 cars of later days. They all kept the 
Transaxle layout for obvious homologation reasons, and Ive heard about the 
appetite for boxes from Euro sources (torque used to snap the input shaft or 
crack the gears) but I know that my mechanic's father (worked on various 
Alfa racers in Australia) had to send away to Hollinger and have a straight 
cut box made up for the 75 1.8T that Colin Bond raced here in Australia- 
extremely short diff ratio and very close matched gears- apparently about 
95km/h in first gear (58mp/h?). This was for sale recently, but the offer 
has been revoked just a few weeks ago- something big in pipelines I think!
   There are a few of those motors around- I believe the one that was used 
here in Australia copped a bit of development work from the Beninca brothers 
(who worked on the GTV6 and 75 racecars in the 80s)- perhaps grouped liners 
and a different intercooler layout, or perhaps just piping- they were never 
fielded with much success here in Australia- the E30 M3 2.5 Quad Throttle 
Four cyclinder was also good for 400hp, so the two were evenly matched- but 
we also had the Sierra RS turbo from Ford and the GTR skyline to contend 
with making the 75 a fair bit of an underdog.
   The GTV6 racer won its class in the Australian Touring Car Championship 
in 85, and the same year, it also won the A.Rally.C- I have some parts from 
this car going into my GTV-soon-to-be-GTV6 very soon :)
