mk2 8v or 16v
« on: 21 June 2003, 22:08 »
Hello All,

Can anyone point me in the right direction of literature concerning the difference in performance between the 8v and 16v Golf.  Im looking for a technical review.   Something like a website or magazine to read!! Just purchased my first Golf GTI 8v and I am just curious about 8v & 16v discussion.

Much appreciated!!!!  

Cheers Manesh

i found a site the other day mate that might be of interest to you www.golfinger.co.uk.

with the 8v and 16v, i've had both and i found the 8v to be quicker off the mark than the 16v, but top end the 16v is obviously quicker. with the 16v i found that you had to keep the rev's quite high in order to get the most out of it. my 8v pulled well from low rev's. in my opinion the 8v is definately the right choice.

any other opions anyone?

hope this is of good use to you matey.

I've never found one 8v to beat my 16v, and many tried.

First gear is level pegging until around 5,500 rpm. At this point the 8v driver is heading for a gear change, whilst the 16v driver feels larger butterfly chamber open, and a little buzzing noise in the back of the brain that says "press accelerator for more power", which is then duly obliged and you sail past the 8v - if you weren't in front already.

The gear change in the 16v should be around 6,800, which will then drop you back to around 5,200 rpm, just intime for the larger butterfly doobrey whatsit to start opening again.

I can only think the 16vs you raced were thrashed or weren't trying.

Sorry,

Justin

I agree with Johnny Boy just for the reason that i have an 8v, so there....... :P

but isn't it always going to be the case that a 16v is faster when considering performance......but if you consider the fact that everyday driving doesn't require you to go above 4k rpm the 8v is sufficient but 16v would be nice coz you know YOU GOT THE POWER!!!!

Im i correct in thinking that the 0-60 times of the GTI's is:

0-60 GTI 8v = 7.9     ;)

0-60 GTI 16v = 7.6  8)      (Figures quoted form parkers)

Is the margin of power that big that 16v is that much of a performer when considering these stats and the difference being 0.3 of a sec......thats formula 1 comparisons which are negligable when considering GTI's ....

Any opinions on this?? ???

I thought the original 0-60 times were more like 8.8 and 8.0 on the 8v and 16v respectively.

The power the 16v has over the 8v makes a huge difference when you call for it, especially for the higher speeds.

If your limit in a "race" is 4,000rpm and first gear, then I'm afraid I had an MG Metro that was quicker than the 16v. You don't need a GTI for quick town driving.

As for the difference between the two cars, they go further than just the engine.

Much of the mechanics of a 16v have been altered, including brakes, gearbox, clutch, suspension and so forth. VW tinkered with everything to build the 16v. Rebuilding a 16v at the moment has shown me just how non standard the car really is.

If you are happy with your 8v then that is all that matters.

Regards,
Justin

The 16V will always be quicker overall, it's just that the 8V feels more responsive in everyday use. I had an '85 8V and the Bruv-in-law an '89 16V, we had a go in each others cars, he said how much better mine pulled away from low revs and I said how much better his went when revved hard.
All down to personal taste I guess, although for everyday use I prefer the 8V, for trackdays and straight line high speed the 16V is the one to go for.

He he he...the same old argument...!!!

I think jonny boy hit the nail square on the head with his summary...!

Hey lee...let me know when your clutch is fixed...(from a different post!)...I have a plan...

There are a number of brilliant roads round my area(in fact theres loads of brilliant roads everywhere when you drive a golf!)...

Basically I propose a race...and I really dont expect to win!...I have a couple of mini bullet cameras....and a DL90 datalogger...(basically does speed,accelleration,G-force...Car position etc

I suggest we spend an  afternoon..filming our cars in competition!...try some 0-60s...and just for humour value...see how fast you can leave me whilst were both cruising at 60...

...then post the videos on the forum for all to see...

Hopefully that should stop any disputes...

Although at the end of the day its got a sh!t load to do with the driver...

and dont slate the metros...those 1.3 gti's will stick to a 911 turbo to 35mph!!!! now that is fun!

Of course it depends on your driving style as to which car is better for you!...If you like to keep the revs up...and get out on some nice open roads motorway/carrigeway...(not to say they dont handle!) then your better off with a 16...but if you like terrorising the rudeboys in their novas and corsas (HA)...banging it round tight country lanes...or getting flapped at by pedestrians...then go for an 8!

(I own an 8 valve mk2 at the moment...but seriously considering a mk1 with 2ltr 16v conversion...I have a feeling that would wipe the floor with most golfs fullstop!)

If Lee isnt up for it...are there any other golf drivers in the South East who want to do some filming?...believe me its fun to stick a DVD of your car on after the pub!...

Might take you up on your suggestion, but we are months away from finishing my car. One step forward, at least two backwards.

My mate has a Mk1, resprayed professionally in porshe yello (i think it's porshe, really bright anyway!) with a 2ltr Audi 8v with throttle bodies!! (think webber twin 45's  ;D) and a high lift cam, and that thing sounds like a race prepped rally car! absolute EVIL! t'was like an earthquake when he left my house the other day and arsed it up the road!! Wud love one!!
So, 87_Project, dont go 16v, just get some carbs! less fuss for more power and beatiful noises!

My tuppence worth.

In fact, this Mk1 is just parked up in a barn doing nothing! and has been for probably close to a year, mite sell me cabrio and see if he'll take ?1500 for it ;D

MK2 8v '84-91

History/Spec

The Golf grew up in February 1984. The wheelbase was lengthened by 75 mm, the track by 23 mm {front) and 50 mm (rear), while the overall length increased by 170 mm and the width by 55 mm. The car's weight increased from 840 kg to 920 kg, yet it wasn't any the more sluggish for it. Indeed, thanks to its new rounded edges, drag was dramatically reduced from 0.42 to 0.34 cd. The GTI was pretty much as the standard car, except for disc brakes fitted all round. The 1.8 engine still produced 112 bhp at 5800 rpm, reached 60 mph in just over eight seconds and had a new top speed of 119 mph. The spec for UK cars was generous at first, including P slot alloys and sunroof -- although these were deleted from the three-door and transferred to the five-door version, which arrived in February 1985. From February 1987, ABS brakes became optional. In August, in came a new-shape grille, left-hand parking wipers and central rear VW badge, while out went the front quarterlight. The 8-valve now had Digifant engine management and new trim, and the five-doors got steelies as standard. Special equipment models in the summer of 1988 celebrated production of 10 million Golfs. The spec included seven-spoke alloys, central locking, multi-stripe trim and tinted rear lights. Available in Helios Blue, metallic black and Oak Green, they proved a big success. In August 1989, the so-called big bumpers arrived; whilst on the mechanical front, a cat became optional -- but 12-hole steel wheels were now standard. October 1990 and power-steering, tinted glass and central locking were fitted to the 8-valve. 1991 was the run-out year for the model, so in October the equipment package was uprated to include BBS alloy wheels, partiallysmoked rear light lenses, electric front windows and 16-valve-style rainbow upholstery. Metallic paint finish was now a no-cost option. The MK2 model range was officially discontinued in February 1992.

MK2 16v '87-91

History/Spec

September 1986 was an important date -- that's when Wolfsburg gave us the 16-valve Golf. The only clue that this had eight valves more than the standard GTI was a bright red badge below the logo -- and if you took a tape measure to it, you'd find it 10 mm closer to the ground. Under the arches sat stiffer springs -- 10 per cent more (front), 20 per cent more (rear) -with modified shocks and anti-roll bars. Even the ventilated front discs were larger, at 265 mm, helped out by beefier brake pistons all round. The 6 in rims wore 185/60VR-14 tyres, and the standard spec included central locking, electric windows and sunroof. The really important component though, lay beneath the bonnet. A cast-alloy, thermally-hardened 16-valve cylinder head, operated by two counter-rotating, chain-driven camshafts. Both shifted competition-spec inlet and exhaust valves and were mated to hydraulic tappets. The set-up needed an oil pump from a diesel engine to stay lubricated. A 10:1 compression ratio and Bosch K-Jetronic fuel injection system helped increase power by more than 24 per cent over the 8-valve. A bhp of 139 at 6300 rpm and peak torque of 121.5 Ibf.ft at 4600 rpm, translated into a 129 mph top speed and 60 mph in just over seven seconds. Developments were pretty much as the 8-valve, although in February 1987, 16-valves were offered with nasty digital dashs -- but few were actually ordered. Everyone wanted the special equipment versions in summer 1988, though. In August 1989, big bumpers arrived, with front fog-lamps and larger side rubbing strips. Although smoked rear lamp clusters and BBS alloys were fitted, out went electric windows. Power steering was now part of the spec. January 1990 welcomed the five-door 16-valve. In November, electric windows reappeared on the spec sheet. October 1991, and a Panasonic RDS pull-out radio/cassette became standard. Like the 8-valve, the model was discontinued in February 1992.


......to be pedantic. (stuff I found trawling on the net)

gotta be 16v tho eh  ;)
