how much do they cost?

tassiegti I doubt your mate has 200hp as this is 146kw and no chip tune in the world gives a AAA engine close to 30kw upgrade...point proved when your std vr6 drives the same..man you really notice 30kw , without a camshaft change and some induction mods etc etc a vr6 engine is 128kw stk..Oettinger germany's leading tuning firm say its useless to chip a normally asperated engine without further mods to the internals...chip only tuning increases fuel delivery and limited timing improvments which equals increase consumption and emitions..for very little kw gain.cheers steve

I've driven it too and can't pick the difference.
One shouldn't believe all the hype about chips on some engines.

[finemk1]

my train of thought...... if your going to the trouble of fitting a 16v and have a bit of extra cash!!....$600-$1000
do ya self a favour and get a aftermarket EMS, yes the VW kjet and the standard injection is good, but u just cant compare with a aftermarket one, ,easier to use, will get bigger gain and will maximise potential out of any engine! im slowly lerning how to use the tuning program on pc befor taking on a laptop and actually using it in the car for road tuning... the biggest problem is tuning cost/dyno time i pay $250/tune. lerning how to is the cost of a laptop but u can steal that. im running a Microtech Lt8 system and it blew me away, controls ignition and fuel and will never go back to stock computers..

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
