Thanks HPR, you rise to the occasion yet again. This quest(ion) is actually a bit on the side of Volkswagen, it relates to gaining what is possible w/o any significant sacrifices on an Audi 2.3E. Seeing it is such a barge compared to a nimble early gen Golf, it seems reasonable to chase mid range torque to me. As a reference, I have this graph from an acquaintance who's brother pushed Techtonics items for 4 cyls and own manufacture for 5 cyls. This is a 2.3E with exhaust only and a 272 camshaft with 110 LSA and 11,4mm lift. It looks to have few, if none, drawback to the original run. However dBilas recommended going for their 266 in comparison to that classic 272/110/11,4 configuration, due no other alterations to the car - makes sense. So I just sold such Schrick cam to a guy with a lighter Audi Coupe, and released the funds for a replacement. It seems to come down to the following: a. dBilas 266/112 LSA/11,1 mm lift - I believe I calculated this to be 224 degrees at 1mm lift. b. Catcams 267/114 LSA/11,2 mm lift. This is stated 228 degrees at 1mm. So any takes with this added info? Here's a dBilas 266 at a Coupe with modified exhaust. A bit choppy, but not too bad. edit: for my Gr B engine, I found that Catcams offers a 284/273 camshaft to suit.
Also here the same, there wont be much in between them ... On Catcams > it has a pinch more lift and 4 degree more duration @ 1 mm and no overlap @ 1mm ( 0.95mm @ tdc) Another option could be profile for MC - 2,2L > Catcams 1002214 - 262 / 110 /11.6 / 1.35 @ tdc ...
Yeah, maybe not such a bad suggestion, but the lift seems a bit extreme (above 11,55) ? For reference purposes, I found the basic configuration of the Golf mk1 1.6 85hp camshaft: 269 degrees, 113 degrees lobeseparation, 4-46/44-8 timings, 9,0/8,6 mm lifts.
Any idea of this cam? Bout 10.5mm lift, mechanical, 38mm base circle. No VW / Audi mark but has CWC marked between lobes and "95" stamped to end of cam.
