20v kit car...

Mates VR6 received chip tune from Power Chip Australia. Quoted improvements are from 128kw to 140kw and 256NM of torque. He also has induction mods and an exhaust system. If you believed what is said, there is no reason why it would not be approx. 195/200hp. It is obviously bs, as I said, there is no noticeable difference. That is the exact reason I decided to save the $1000 he spent on the chip. I still stick to my belief that unless you make significant improvements to an engine's output, you are not going to notice a significant difference on the road, apart from psychologically!

I agree aftermarket efi systems are really the only way to fly...so much potential and a lot of fun to boot....although the later factory cars systems are more advanced with more potential which brings the cost factor into a different ball game...chip tune mk4 110kw up to143kw without altering anything else..nice and easy...so the future is bright when playing with later cars cheers steve

tassiegti on paper you may think theres not alot of diff between the 2 engines...from my experience with both engines in stock and modified combos the abf blows the door handles off a stk 16v...the preformance potential of the abf normally aspirated is up to nearly 200kw thats over 270hp..of course the internals are also heavily modified tio acheive this result. at this point the stk g/box has already cried enough!!!!!, as the sounds of marbles in a tin can echo in your ears,, the stk box is good for 200-240hp..its the other parts of the drive line which also suffer cv's ,uprights, wheel bearings etc.have to think what ABF stands for absolute bum?????? cheers steve

There is infact not much difference. The ABF develops its torque differently due to having a different rod:stroke ratio due to the tall block configuration. As a result, the peak figures are often around 400rpm higher than a comparative 9a/6a 2.0 16v.

The ABF head flows slightly better as the casting was cleaned up (exhaust side still a joke, however), the main benefit is in the cams - it was good to have Digifant III injection but the mapping was not very good. There is a common misconception that the ABF shares a cam specification with the 9a - ie weak inlet cam. This is not true, the ABF has the best standard 16v cams of all with considerable valve lift.

In terms of general engine specification, the ABF is not exclusive in its ability to make 270hp. This is possible with a 9a. The VWM ABF motors making such power figures had tapered throttle bodies and an entirely different head casting with a 7deg cut on the block for valve clearance with 13.5:1 compression pistons. One could use the same parts in a 9a.

A 9a with ABF or KR cams and K-jetronic injection will perform much the same as a stock ABF; the ABF will just develop torque higher due to the alternate rod:stroke ratio.

The biggest benefit of buying an ABF for a transplant is that it is a younger motor and one can assume it then has lower mileage. I chose an ABF for my Mk1 over 2 years ago and ahve since turbocharged it and it has proven very reliable.

great to get a bit of dutch expertise on this forum ..i agree with your evaluation between the two engines..my personal experience with with a std abf over a 9a or kr have been in the abf favour ...as far as a modified abf its another story.....i currently own a mk3 golf kit car no17 which was owned by austrian rally champ Dumslarger [spelling needs check] it has the VWM engine which i unfortunatley destroyed at a state rallysprint....this engine is a work of art..the block needs also to be milled 7mm which works in favour with the 7degre valve clearence.. all the valve stems are also machined down to help increase flow at the head .the Lehman engineers are smart and the head flow was improved up to the FIA homolgation standards.I also understand with discussions with VWM that all the remaining mk3/4 rally bits were bought by a dutch firm do you know them? are you using a k4 turbo on your latest upgrade more info please..have a std abf in need of a tickle up cheers steve

Hi,

Wow, I wasn't aware people had any VWM cars in Australia!! I have a number of friends there who would no doubt be interested to know this!

My latest motor is one we built using a hybrid T3/T04E turbo from Leiderschrichten Tuning. It runs 20.5psi of boost and uses a modified Audi S2 exhaust manifold with the fifth cylinder branch removed. The motor has custom made cams from CAT CAM which are 244in and 258ex, both with 10.95mm of valve lift. The head was modified by Bauer Motorsport of Nurnburg in Germany and uses 34/28.5mm enlarged valves. Mahle supplied the pistons which are 8.1:1 ratio and we had to modify them in-house as we had trouble with the wrist pins. We were not able to get the motor to run well with the Digifant III system so have chosen a system from Autronic in Australia, which is very good.

I am currently running the motor in on a base fuel and ignition map we programmed on the road so am yet to dyno tune it. I understand it will be good for around 300ps at the wheels.

I am not sure who in Holland supplied some VWM parts but we have a number of customers using VWM things here, but have never supplied the parts ourselves.

Thanks,

Hanse

hello Hanse ,there is two VWM mk3 golfs and two mk4 tarmac cars..also a mk1 which was developed with factory assistence. other than no17 kit car the second mk3 gti is a new body shell and full components for group a rally.engine is std abf and 02a g/box with VWM LSD center which in it self quite compact....there you have it a new never driven mk3...has std gti running gear and a full SACHS adjustable suspension kit with external resivioirs..the famous mk1 golf is an xfactory car built in australia in 1976 when we had a local plant...golfs were assembled for 1 year in melbourne.this car runs 165hp from 1600 with bmw mechanical pump running from the camshaft sprocket..4 trumpets very close to the fire wall and WOW it barks loud..the cam is Oettinger from many years ago with full bilstien and many choice spring settings.runs hard to about 8000 and sounds like a M3 at full noise. gearbox is a ratio 4sp with a very early style quaife diff center which works your arms..torque steer of the 70's . this vechile run between 76-80 during our famous Bathurst race circut with mixed results...the 4sp really limited the potential as it revved its guts out over 160kmph with 13in wheels on 3 piece bbs with slicks. thanks for your interest and it good to let the world know we may be a long way from anywhere but still have a finger in the golf pie..cheers steve ps what is the name of your buisness and what do you speacialize in ?

seat gti motor?

Hey people, just joined the forum. Have been on the UK Club Gti forum for a few years now, I've learnt heaps from them.
I have an 89 Gti 16v specially ordered right hand drive in Germany then imported to Australia, so it's the euro spec engine. The car is very quick for the engine being standard. I recorded a 7.5 seconds to 100 on a friends G-tech meter. It's a very smooth motor and while being responsive low down is a little peaky up top. The revs build so quickly when you get about 4.5-5 grand, below that it's pretty similar to an 8v Gti.
But the time has come for more, and soon I'll be able to tell you if there is much of a difference between KR and ABF engines(in drivability), as I'm doing the swap. I'm keeping the inlet and exhaust manifolds and using the K-Jet injection. According to the Club Gti forum the digifant(digipants) injection on the ABF motors(in seat and mk3 Gti) is a little restrictive, but can be chipped. And when coupled with the K-Jet and making sure the small adjustments on the K-jet system are working properly I should expect closer to 170 horses compared to the 150 std.
I've had my car RR tested before and got 100hp at the wheels. Will be interesting to see what it gets after as all the parts will still be std. vw stuff.
My ABF motor has come from a uk mk3 Gti not an aussie seat, cost me $1000 for the motor, gearbox, manifolds, and loom, then a further $1000 for the import.
I am using a VR6 subframe to drop the motor a little lower as to avoid these bonnet clearance issues(only in a mk2).
According to both people in the UK and one guy from Tas who was putting an ABF into a mk1 there are no clearance issues, but I don't know this first hand.
Sorry for the long first post. But hello again.

[20v kit car]

welcome ausgolfer to the abf bretheren...very keen to hear how your results turn out....sounds like you are going for smoothness and reliability which makes a lot of sense espeacially with a road car..great to hear there are more people getting invovled with new and fresh ideas cheers steve

seat gti motor?

Yeah we'll see how it goes when it's in. Thanks for the welcome.
The extra capacity will really help with the low down pull.
From what I've heard there's not a lot of point changing the cams in a ABF or KR engine, and most that have done so usually end up putting the standard cams back in. Unless you are building a full on race car, the only worthwhile cam mod I've heard on a KR of ABF is the twin exhaust cam mod where you modify a KR or ABF exhaust cam and put it in place of the inlet camshaft (because the exhaust cams are slightly wilder than the inlets).
Who knows, maybe a supercharger would be next on the agenda. If you put an ABF or KR cylinder head on a 2L 8v engine block(code 2E or ABA in states) you get a compression ratio of around 8 to 1. You need to swap over the oil pump drives and intermediate shafts etc. Also you'd have to get a pocket cut into the pistions for valve clearance. But I'm certainly thinking about it.
I have an old pair of KR cams sitting in the garage I could do something with. So many bits, not enough money.

welcome ausgolfer!!! good to see i finally have another melbournian on site...

[DOHCDAVE]

Welcome ausgolfer, old set of kr cams lying about you say , i've a 1.8 16v PL prefix motor in my mk1 still trying to figure out problems with running the bloody thing but was wondering would you be interested inselling the cams as the motor i've got produces 123 hp and i would like to take that upto the KR stats. If not no stress would love to check out your cars as i'll be in melbourne in october for the weekend and would also like to catch up with some of the other members that live there also. Be good to put some faces to the names that i see in the forum.

Guys still trying to post pics of the alt bracket some of you asked for in parts for sale. For the new guys i fabricated a bracket for the my 16v from an old one off i think a 1600 and made it fit comfy away from the inlet/m. Got one photo uploaded but can't figure out how to show it in my post so that it's active when you put the mouse over it. Any suggestions?
And welcome again ausgolfer, the sites word is getting around and it's growing every day which is good to see as i know i've told countless numbers of late mod watercooled owners up here in QLD about the site and look frward to chating with all of them.
Bye for now
