Title: Supercharging an 8v
Post by: Gavv8 on 25 February 2012, 21:33
Does anyone know what is needed for an 8v supercharger conversion, is it worth it? and what gains would you see.
Title: Re: Supercharging an 8v
Post by: Wayne on 25 February 2012, 21:35
Nope not worth it, do a search this question has been asked many times.

you will see about 150/160bhp which with all the work required is not worth it.

Ok, so what would be the most cost effective route for a power upgrade?
Title: Re: Supercharging an 8v
Post by: joebickerton89 on 25 February 2012, 21:45
the 2litre 16v will go nicely and is 150bhp standard :D

Post by: Gavv8 on 25 February 2012, 22:05
This has probably been asked many times but can you transplant the 16v head on to an 8v block or is that just a stupid question.

Most people on here will say it's just easier to buy another car i.e. a 1.8t. Not a lot of gains to be had from a NA engine over a turbod one tbh

most bang for buck is a 1.8t conversion. Only do a conversion on something that cant be bought, eg don't drop in a 2.0 16v just buy a valver :)

there are many many many many conversion threads, either do a search or check the stickies where there is a 1.8t conversion thread

Ok thanks for the input, it needs to be a conversion of some type as i will be keeping the car and want it to stay looking standard.

Remember the G60 was a supercharged 8v, they thought that was worth it when they made it,  personally, as a project and as i one off, its something i would like to see more of,  its easy on the 8v due to the space available, no it wont make record power, but it WILL be something special!   personally, i would say DO IT,  it will be the biggest waste of money you ever spend, but the most rewarding and fun, or do it to a 16v,  same deal but more power...  But then where does that stop,  why not slap an R32 engine in there.. and superchage that...?   because you want to supercharge your 8V thats why... DO IT!  make it something special,  you will look back on it for the rest of your life knowing you DID IT!!!!!

I wish more people would play with foreced air on their standard engine,  do you want massive power, or the most power from the engine you already have?    if you want the latter,  go for it  but be warned you need to sort out aftermarket fuel injection, its not as scary as it sounds when you read up a bit about it and grasp the theory of it.  its all do-able.

 If you want massive power... dont ask questions about supercharging your golf... buy a lambo.      but thats not what you want is it  :wink: :wink: :wink:

I think we all know that if horsepower is your ultimate aim there are cheaper/better/easier ways to go than a mk3 golf, i agree with the above^ and what i'm looking for is a project that will give a modest power hike but keep everything looking stock.
I've got a really nice standard 3 door 8v with a good history and strong and healthy mechanicals that i'd like to do something a bit different with, i've looked at a few of the supercharged clips on youtube and i like the way they sound and drive as it seems like a good way to keep reliability and driveability everyday without creating a highly strung pain in the backside and it also follows the VW bloodline so to speak.

DO IT  :laugh:  Dispite the people telling you to fit other engines (totaly good point)  every 8v owner will be green  :evil:

G60 is a whole different ball game, various reasons why VW did it (mostly rallying) but these days it is old tech.

This thread is worth a read: http://www.golfgtiforum.co.uk/index.php?topic=101392.0

Oh im not going to pretend supercharging an 8v is a waste of money and will make no real power, but if i was walking arround a show i would be attracted to the 8v with the supercharger on the side... its diffrent, its fun, and i would love to see more if it. if i came accross a MK3 with a 1.8t, i would take a look and walk on, because i see that every day in my passat estate lol.  If you want power... sell the MK3 move on... if you want to be something special... do it.  If you you want a powerfull MK3, put a 1.8t in it, you would LOVE it,  but not as much as the sound of the supercharger.  :wink:  If you dont have money to waste,  spend it wisely,  supercharging the 8v is not power for money,  its being diffrent for money.   Think about what you want out of it.   Im very much pro the idea as i love to see it,  people say dont be so stupid, because you would have the same result by getting a 16v golf.... totally fair point.... cant argue that.

Those threads^  are great and do highlight the expense and level of technical involvement but i still think its where i'd like to be with my car.

G Werks, or was it the phirm? Well one of them made a 320bhp g60 engine. I'm sure you can get that from the 2.0 8v  :wink:


They spent a lot of money though

Considering how fragile the G lader supercharger is, 320bhp is nuts. :shocked:

TRUST ME.. the sound of a PROPER Turbo pisses all over the sound of a tourqless supercharger.

no way would i swap my set up for a puny SC :evil:

TURBO THE 8V  :laugh:

Title: Re: Supercharging an 8v
Post by: F17BAD on 26 February 2012, 15:33
Turbo conversions on the 8v are done lots in the states, you need the head off a 2.0 8v engine thats found in the  mk4 golf GTI 2.0

its a crossflow head.. iv just bloody scrapped one too!!

i think turbo kits are readily available for this set up in the US.. I don't know loads about this one unfortunately but over on the Vortex forum the info is all their to see..

Turbos are much better than S/C.. more Torque and thats what wins u races  :wink:

Thanks bud, also has anyone tried nitrous on an 8v and what kind of results did they get?.
Title: Re: Supercharging an 8v
Post by: murraymint on 26 February 2012, 15:48
I'd say get the turbo sorted first lol.

crossflow 8V's will turbo easy     loads of room round it none of the parts are all that spectial or complex so you'd be abel to do all the pipework without much bother.

as said if you want to know about boosting motors read vortex tho a few differances worth noteing between here and there,  the ABA is 9:1 compression 8valves here are generaly 10:1    but the petrol here is quite  alot better.


superchargers are brutal when it comes to torque,  get a nice big eaton and halt the time your actualy holding it back trying to stop things twisting themselves to death.  much more responsive than turbos,   turbos tend to make bigger bhp numbers for less money  it allways used to be the case that big turbo were crap when it came to drivablity but the modern ones are amazing compared to there predicessors.  main problem is when bolting a big SC to the frount of a vw 8,16 or 20v   is the frount pully  as they can absorb a LOT of power eaton M112 needs something like 90 HP  whene it spinning its fastest and blowing its hardest   vw frount pully wont do that

insurance loads your policy 1% per happy gas fueled pony.    ( ouch )   
it's good to add a kick to a car but it won't turn a slow car into a fast car just one thats occasionly fast, it' optimal for drag raceing but not spireted driveing better off with tuenign thats helping all the time for that.

no2 is bloody expensive to refill  when your buying refills per LB    it get a lot cheeper if you get an air products or boc account and get a 50ltr bottel to do your own refillls with.

then you'll put the biggest jets in you can and use it all the time and it will go bang

I'm beginning to lean more towards a good reliable turbo conversion, i love the idea of the s/c but the costs are frightening and the question about nitrous was more to see if anyone has gone down that road but it seems like more of a sledgehammer to crack a nut type of route.
I think i'm going to have a good read of all the vortex threads then start getting an idea of prices and see what i can use second hand and what needs to be new.
Title: Re: Supercharging an 8v
Post by: Wayne on 26 February 2012, 19:52
For the work, hassle and expense of a turbo conversion you may as well drop a 1.8t in.
Title: Re: Supercharging an 8v

eaton m90 on a 16v got to be more fun

Post by: F17BAD on 26 February 2012, 21:02
superchargers just don't do it for me

after seeing a few SC powered VR6 cars, my brothers Mini cooper S (mapped) i can only say IMO the Turbo is KING

Iv seen G60 powered Golfs etc with so called 260 bhp that just look as slow as a 8v  :laugh:

Turbo all the way, i agree with wayne TBH about just dropping int he 1.8T,  but it would be nice to see some 8v Turbo conversions on these shores

just something different aint it
