Cams for "Project GTQ" shipped

[Swann, Benjamin R. (BSWANN)]

John,

To the best of my knowledge, the break from Solid Lifter to hydraulic lifter
for the AUDI/VW Inline 5 Cylinder motors came about in 1984 when the
displacment went to 2.2l.

Therefore, all I-5 engines since '84 have hydraulic lifters and a good check
is:

2226 cc = hydraulic
2144 cc = solid

Here are the specs for the Naturally Aspirated Hydrualic lifter 10V I5
motors that would be addressed by a camshaft upgrade:

	 		'85-87 4000S quattro		 87.5 Coupe GT 2.3
80/90 Quattro
				and GT Coupe			and 5000/100
                            
 Arrangement: 		Front mounted, longitudinal 
 Type: 			5-cylinder, in-line 
 Bore: 			3.19 in. (81.0 mm) 		3.25 in. (82.5 mm) 
 Stroke: 			3.40 in. (86.4 mm) 		3.40 in.
(86.4 mm)
 Displacement: 		136.0 cu. in. (2226 cc) 	141 cu. in. (2309
cc) 
 Compression Ratio: 	8.5:1 				10.0:1 
 Horsepower (SAE Net): 	110-115 @ 5500 RPM 		130 @ 5600 RPM 
 Torque: 	 		126 ft. lbs. at 3000 RPM 		140 ft.
lbs.@ 4000 RPM 
 Cylinder block: 		Cast Iron, tilted 27° 
 Crankshaft: 			Forged Steel, 6 main bearings 
 Cylinder head: 			Aluminum alloy 
 Valve Train: 			Belt-driven, overhead camshaft 
 Firing Order: 			1-2-4-5-3 
 Cooling System: 	Water-cooled, thermostatically controlled electric
fan 
 Fuel System: 		CIS fuel injection 	 	CIS-E III engine
control fuel inj.
			w/ oxygen sensor		w/ oxygen sensor &
knock sensor  


Most of the '84 on cars also had an air pump eccentric, as well as a
leftover fuel pump eccentric from the pre-fuel injection days.  Also, I have
observed, that the turbo camshaft is very similar to the 87.5 GTQ Cam I
sent, except for the cutouts at the cam foot, which I understand is a nicety
added in the '87 timeframe.

Best Regards,

Ben Swann
