Title: Supercharging 8v
Post by: avengedslayer on 07 April 2009, 09:04
Is it possible to supercharge an 8v or is that just silly?,  :grin:

If you don't mine a bit of fabrication....theres a list of guides within maintnence (by bored_welsh_lad) that have full info

Turbo is easier because you dont have to make a drive off the engine.

so can you bolt a turbo onto it or something? :smiley:

Not exactly a bolt on job as you have to change the exhaust flow to power it!
Plus the plumbing to air intake etc.

Anything is possible my friend. an 8v can be turbo or supercharged but is it really worth it? As its been said many times before, a very heavily modified 8v will be on the same level as a standard 16v, so its better to start with a 16v then modify it. a supercharged 8v will put out about 170-190hp (my prediction) but a supercharged 16v will put out well over 200 horses.
Its your money and your car, so do what you want with it. Im dying for a boost car especially supercharged but im gonna hold off until ive got a decent engine to supercharge, no point in doing it to my 8v.

I agree if you want huge power the 8v is always gonna come up short! My route would be to convert to 20vt power! The boost will be there and it has huuuge potential for power!

the 20v 1.8t is the easiest conversion (as there's lots of specialists and parts avalible), then again I wouldn't turbo the 2.0 8 or 16v as both would require some substantial head,piston work for reliability.

my fave would be a properly supercharged 8v as the low down torque would be  :cool: ok so 160-190bhp (depending on charger,pulley and chip) isn't much but diesel ammounts of torque would be fun without the soot or noise!
(the yanks are running around 220bhp with engine work......16v killer  :evil:)

but with a diesel you leave soot trail and you sound like a tractor  :tongue:
cant beat the sound of a whining supercharger

have you driven a mk4 GTI TDI or GTTDI? 115/130/150 bhp?  :tongue:

the 115's are quick but the 130's have monstrous bottom end torque. very quick off the mark. cant commenton the 150's as never driven one but based on the 130 alone id recommend them

edit: still prefer the idea of a supercharged 8v though  :cool:

supercharging a mk2 is like giving an 85 year old man a pair of nike trainers and a bottle of lucozade. It just aint gonna go right.

lol

i doubt the internals between the mk2 and mk3 engines vary that much. same materials, different bore/stroke etc. obviously i wouldnt dare try charging my 246k mk2 engine  :lipsrsealed:

try this for a good list of suppliers golfgti.co.uk (http://golfgti.co.uk)  :wink:
oh and supercharger wise..most people use a mini one as there fairly cheap and avalible (thanks to the cooper works using a brand new supercharger!!)

i'd always go for the next charger up the m62  compare it's displacement to the g60  and you'll see why.

8 or 16v   will make massive amounts of bottom end torque with m62    m90 on a 16v would be serious fun tho

Both supercharging and turbocharging require massive amounts of planning before you go ahead with it...

after talking to a lot of people there seems to be a cheap way and an expensive way...

the cheap way is.. piggyback ecu, single 5th injector, brackets for charger, charger, spaced head gasket, vr6 fuel pump and belts...

sounds really easy but its not and should not be taken lightly.. im looking to sell my mk3 in the near future and buy something else.. but im going to pick up a mk2 cheap and drop a 2L lump in that charged.. i have most of the parts now so should be fun.
