Thinking of upgrading the valver with an ABF. It is worth adding a G60 to it as well? Is it as simple to do and has anyone here done it/got one?
After some pros and cons.
-
Am thinking of doing this with mine theres a topic in the mk3 maintaince section
-
its not so straight forward. Needs some brackets for alternator relocation. ABF + eaton M62 is easier with the eaton going in place of AC pump on the ABF. Still needs fabrication to mount it.
-
Use the search function there's a whole thread in mk3 section with loads of useful links.
Not a 20min job but do able. A chap by name of Rysho did one in a Seat a while back.
G60 perhaps not the best option as expensive and design has been improved since then, as mentioned Eaton, lysholm, rotrex etc etc
-
G60 isn't really big enough for a 2ltr 16v
std G60 1.8 8v is 160 bhp book, std ABF is 150 bhp. to get a worthwhile performance increse you will have to run a very small pully and that dosent do the g60's life expectancy any good

You can *just* push 300bhp on a 2l 16v g60 on a 68mm, as shown by jezzag60's build on corrado forum, but its a proper build, your talking scat rods, emerald management, water injection, big injectors, ported head etc etc.
240ish seems to be about where basic 'budget' builds are making, which, when compared to a ported, cam'd, 65mm'd 8v g60 which generally make 210-220, hardly seems worth the extra expense and massive effort.
-
the 20 ish bhp differance between a twerked 8v g60 and a budget 16v g60 to me a very big hint that the charger is pritty much out of puff. if you really put the effort in on a 16v and use a fully worked over audi v8 head and forged bottom end with some really nice big barrel throttels you can get more than 240 NA

I am (slowly as time tight) building Mk2 ABF with ported head, Eaton M62 (Merc kompressor, not smaller mini M45). This has also been ported and the roller vanes have been coated with a heat resistant finish.
This will be fast road 'every day use' car so wont be a tempramental dyno queen, but built to be solid, torquey and reliable.
Air con bracket will be adapted, ARP head studs and maybe rod bolts, then wit MS or similar.
There will be some fabricaion but that's half the fun I think. It' all going without toomuch of a hitch so far.

Eaton M62 will be a better bet than a G60 blower.
-
Thanks for the advice guys. I'm not after a monster racer.just a tidy everday car. Ill do some research into these Eaton superchargers.
-
i would be very tempeted to look at the M90 from the jaguar :wink: nice big charger so you can get the airflow without the revs it's all more efficent less stressed and won't whine half as much also there is the potential for a hell of a lot of air if you want it
-
Wow - M90?????
'Tis a big old beast mostly used on 3.5 litre plus production engines, plus really quite a porker I think. Actually I wonder if it would even fit??
M45's were fitted to Mini Cooper and Mercedes of 1.8 to 2.3 litre I think. (not good on my Merc knowledge) The M64, (my choice) is a lot rarer than the M45 and was used mostly in the UK by Mercedes on I guess 2.8 to 3.2 litre engines.
Beware when sourcing one though as I ended up with a Merc Kompressor from a higher capacity engine and it turned out to be an M45(!!!!!) which I had to resell. Merc were very canny at sticking a Kompressor badge on a car, and totally underspeccing and gearing it so it only ran puff at low revs ( to help a multi valve engine have torque to pull a heavy car away) then at mid revs an actuator would disengage the charger and bypass the inlet. total token bollocks of a set up if you ask me. The drive wheels for the one I saw I think was 230mm (!!!!) this meant it got spinning up quickly at low crank pulley revs, then was disengaged at mid revs.
Anyway my M64 has been rebuilt and the cluth removed so it is permenantly on :evil:
-
They get quite hot twin screws :wink:

They used M60 on some or most, M45 is 1.6 and below and will be no good for a ABF

Can you fit a V8 in a mk2? I've never come across that conversion, will have to look into this :evil: :evil:

Lol, he's talking about just using one of the V8 heads (imagine half a V8, well sort of)
-
Haha can you do that? Or is he having me on?

Not 100% sure, from memory the Audi V8 was 2 ABF heads on a common block.

indeed, eatons are about the only charger to have an adiabatic efficiency worse than a g60 :lipsrsealed:

the some of the audi V8 heads offer more potential than the std ABF head.
