I sent my ABF cams away to be properly measured up - here's what he got: Intake Cam: Duration 219 deg @ 1mm, 10.8mm maximum valve lift (that's a LOT for a stock cam ) Exhaust Cam: 220 deg @ 1mm, also 10.8mm maximum valve lift Versus KR cams: Intake: Duration: 218 @ 1mm, 9.6mm lift Exhaust: Duration: 226 @ 1mm, 10.21mm lift ****** So the ABF camset is the hottest of all the VW 16v cams (despite what that dick from C&R said in The Golf once about ABF owners needing KR cams for performance ). We came up with a theoretical powerband of 1600RPM - 6450RPM, which is about what you'd want in a pretty stock street engine. This matched the figures of my stock ABF perfectly and also explains why some ppl have said their car felt more lively on ABF cams than KR ones. Discuss
Thought it would be worth a share - cost me $60AUD in postage!!! P.S. These are the SEAT abf ones, so if someone could do some VW abf ones to confirm they're the same, that'd be great
They are not the same. I had an ABF cam lying about that was used for a twin exhaust cam mod. The VW ABF cam wouldn't line up with the ABF ones. They may offer the same lobe dimensions, but at a very slightly different point in it's rotation... Does that make sense? Can't think how to term it better.
Makes no sense at all - ABF cars from Seat and VW had same power outputs, have same manifolds, intakes etc etc
Nice findings mate Someone's told Tub his ABF cams might be from some 200+bhp monster ltd edition Ibiza Edited by: G_V_K
They did a ~260bhp replica ish F2 Ibiza. Lehmann were engine builders IIRC. Put the part nos up, if they don't check out with both ETKAs then they're not what you think they are.
No Mr. Bocking - you have it all wrong. I was saying they did a crazy ABF engine Seat, limited edition thing. And was saying that the different tappets and cams might have been something to do with that. I wasn't suggesting my ABF cams where 260bhp ones!
So how come the ABF has a lower specific output than the KR (75 Vs. 77.2)? I assume because the head is a bit more restrictive and the injection is a bit more stingy with the juice.. Am I correct in thinking that a higher lift and lower duration should give more mid range torque and lower HC emissions? ABF cams in a KR on K-jet should be interesting..
so the lift and duration are the same, but the cam timming is different. But does the seat have the same timing sproket with the same timing marks tho.....
I need an update or I still can't use these things properly. 053 103 265 GX - Cylinder head with valves and camshaft 053 103 265 DX - Cylinder head with valves and camshaft 1st number is listed against Golf only whilst Ibiza has both.
Yeah, SEAT released an Ibiza CupraSport F2. It was rated spot on 200BHP and limited at 7,800rpm (can't remember the torque figure). 0-62mph was 6.7 secs IIRC The timing figures of SEAT and VW 16v cams are the same. My last pair of Kents came out of a 1.8 16v and in the Kent catalogue, the timing figures are the same for each SEAT and VW sets (31-67/67-31). The KR has a higher specific output because the ABFs are tuned like crap from the factory (AFR all over the place) and also, the displacement increase doesn't really boost horsepower - they did it to address the torque problem -> the KR couldn't pull around a Corrado or Passat too well. The ABF head has better total flow in stock form (albeit only just) aswell. In a way, the digi setup ABF is worse than a K-jet equipped stock ABF. The best thing I've done to my engine is lay down the money for a full standalone system.
There was only one 200hp Ibiza F1 clone that was made by SBG / RSD - the motorshow car in Bronze - this was a stock motor with some oettinger cams and a rechip and supposedly made 200hp - I doubt this figure since the six super-6 rallly ibiza's that were made for the UK champs had even wilder cams and a 4 branch manifold and made 190 bhp. The proper F2 ibiza's were indeeed with Lehmann engines but these are very specialised with solid lifter heads and cams that would not be mixed up with ABF ones Cheers Rob Edited by: RobT
Didn't they do a production run of a powerful version? I remember it being on an old top gear (when i was a wee likcle nipper) and it was daft spec, but about 30k!
