Charging the ABF

[elcristoff]

Right,

Before i begin, i have done a search and all that entails is a 1.8 16v running a Eaton 45.

I am thinking of charging my 2.0L 16v using a Eaton 62 Charger out of a Merc Kompressor. There are a couple of questions i would like to ask first.

I pressume i would need a new inlet manifold, and a while ago i saw a topic of some guy turboing his ABF and he was using a modified inlet off a Audi S4, would this work for a supercharger aswell?

And pulley ratios? I'm new to forced induction so could someone explain this to me?

Cheers,

Chris

not a step by step guide but may help in applicable research

look for a guy called MOINK10.

he brought a 16v off me and believe has charged it.

I dont see him on here very often but may be a good shout for some advice.

Rods will be your problem depending on how much power your going for. Two metal headgaskets will drop your compression a bit to help with detonation.

Pulley ratios are basically how fast your making the supercharger spin in relation to the engine speed. In general the faster the supercharger spins the more air it pumps and the more power you can make, ALthough the supercharger starts losing efficiency when it gets too fast, so you have to choose ratios wisely depending on the charger, eaton should provide specs on this though.

Yes you will need a new inlet manifold, you have a few options, the audi s2 five cylinder one with the end runner cut off. Or weld half your 16v manifold to the back end of a 20vt manifold. Along with this you'll want an intercooler and charge piping.

Then you need to think about how your going to get more fuel into the engine, the stock 16v ecu isn't really the easiest thing in the world to get mapped for more fuel. So your probably looking at having to go to something independent. Cheapest will be megasquirt but you won't get much customer care with it. Then there are plenty more expensive ecu's out there, how bigs your budget?

All in all a lot of effort and money for getting almost the same effect as buying a 1.8t and bolting it in....... Which has more scope for power on standard internals.

mike said it all, most people do use s2 (5-cylinder) ones, but they are becoming harder to get

sums it up perfectly dare i say it but all depends on why you want to do it really

if you are after power on the cheap then consider the 1.8t with a turbo or still a supercharger as it's standard setup, compression etc all ready for forced induction or maybe gassing it as alternative would be even cheaper for temporary speed thrills.

if you want to do it 'just because you can' then go for it but be prepared to be a mule for development and breakages and custom parts etc

worth looking up chrisdaman's purple 1.8 16v supercharger project for a few clues what you are letting yourself in for as he had a couple of top helping hands on the project and there was still the odd few 'interesting' dilemma's

if it's just a weekend fun toy that you wanna try and blow up for the fun/thrill of it then why are you reading this - get out there and start ripping the head off it

Very true and I do agree with it BUT I hate these comments!

Yes it would be cheaper to fit a 1.8 20vT.... yes it's more scoop for power at very cheap and easy mods for the 1st two stages BUT stuff it!

Be different, I haven't seen an Ibiza ABF supercharged, good work for doing it! If I spent the cash I have on my thottle bodied Ibiza on a 20vT instead (almost did) I could have a 300+bhp monster by now!

**** that!

Do it, always nice to be different and something I like to see! Good luck to you fella!

Aha, cheers man. The way i see it is if i wanted a car with A 1.8t in it i'd just buy a new car. It's rare to see charged Ibiza's. I've been doing a little research and the most pain in the arse bit seems to be making a brakets (i can't weld, i wouldn't know where to start )

I've heard some good things about Emerald ECU's but they are £££. Megasquirt seems to be within my price range. Is their customer service really as bad as people say?

There is no customer service with megasquirt, its freeware/development technology. ALthough if you speak nicely to toyotec from club gti he can make one for you to your requirements and will help you lots. Making brackets and the manifold will be the hardest bit to get done if your not very good with fabrication etc yourself.

 

[elcristoff]

Cheers for all the comments guys. In regards to the S2 inlet manifold, is it a simple cut the end runner off and weld it over job? so the remaining 4 runners match the ABF lump perfectly?

I'm hoping to hit 250- 280 BHP. Is this acheivable? Obviously i want to start lower so that i can run it on standard interals for a while, so i can save some dollar to get uprated bits and bobs

I've PM'd MOINK10 to see if he can help me with bracket designs.

Cheers guyss

I charged mine 4.5 years ago but had car off road for 3 1/2 doing rebuild now.

I was running eaton M45 on std management. Was a trial really. Was using larger pulley to drop boost to 3psi and was doing 193bhp. I used an adjustable fuel pressure regulator to up fuel enough for the 3psi boost.

Was few issues though: When using original eaton pulley at 1st, the map sensor kept maxing out after 3K rpm, which nose dived the car . . . To over come this i fitted the larger pulley to drop boost down. 193 bhp was acheived with VERY lumpy cams (not good for supercharged engines) and with larger pulley boost dropped off to 0 after 6K rpm. So really, 193 BHP was without any real boost.

Plan when finished (hopefully this year) will be running std pulley for more boost and trying to map std ECU to cope. I have a mate who plays with ECU's and he's confident we can sort it out once we have fitted new map sensor.

Come one Steve use some proper management! The standard ECU doesn't have much parameters for you to alter! Get aftermarket first off!

ste are you using a M45 on an ABF?
that's a bit small ain't it?
wouldn't the M62 be better for an ABF?

would love a supercharged ABF....hmmm

 

[Fl@pper]

according to manufacturer specs the Eaton M45 displaces 45cu ins/rev or 750cc. In street car form it is recommended for engines of 2-3 litres

M62 is for 2.5-4.0 litres but i guess there's a lot more flow testing/logging/maths/compressions/efficency and research etc involved for an exact answer

 

[suj]

well i read that the m45 was better for the 1.8 KR engine

and people used the M62 on the ABF

not saying i am right, just what i read, would like to learn more

 

[Fl@pper]

only glanced at it myself suj - couldn;t be bothered to be honest
