8v Distributor woes...

[djsteveyk@shaw.ca (Jody Bailey)]

This is the info I have found on the 3A...
108 HP @5300RPM
121 ft/lbs @3200RPM
1983cc
10.5:1 cr
92.8 stroke  (some info says 92.71)
82.55 bore

This info is of course with the Audi head on it (hydraulic lifters) and 
dual knock sensors.   I believe Dan is right and the JH/3A combination will 
leave the cr the same (10.5:1) and would only recommend running this combo 
with a knock box unless you have acess to high octane gas everywhere you 
go.  I got some knock with this combo without the knock box under load in 
certain weather conditions, albeit not all the time.  I have since hooked 
up a single sensor knock system (grafted into existing CIS) and shaved the 
head to the Bently specified max allowable 132.6mm and have no problems 
with pre-detonation. HTH
