doubt they are still available, also what are you going to be putting it on...

I don't think they're still available,... unless you go on Ebay or something,...

judging from your username, (sorry if this is a terrible assumption) you might be considering fittin it to a 998, i wouldn't bother..... Webers are far too 'large' for a 998, especially when you'll get better economy from a large single SU like an HIf38/44, The 44 is ampl even if you were going past 150 ponies under the bonnet!

Depends on the state of tune....I will be looking for a downdraft like that when I slip a 12G940 onto mine and slip something meaty into the camshaft slot

There isnt any reason why you cant run a weber on a std 998, it just needs to be set up properly, you wont gain anything apart from some nice noise so its not a 'cost effective' upgrade for a std engine.

i'd say save the weber for an engine worth putting it on comes along mae, then you cna really have some fun tearing up tarmac

I wouldn't have thought it'd be cost effective on any 998 when an SU will do the trick with no fancy manifold or possibly bulkhead box/bonnet buldges, or trying to sort out overfuelling most of the time.

true it will sound good, but it'd be good to have some go to match the show. At best you'll pick up one or two horses at the higher rpm's

having said that, i'm young and impressionable, and probably not as experienced as you lot, so i'll go back and hide in my hole lol

**edit** or you could try and get a Reece 'fish' carb, and it's all adjustable, no swapping needles etc ever again! though they're super rare now lol.

cheers for the replys guys, the carb isnt that much bigger than mine now, infact the first of the two venturys? (buterfly things) is smaller than mine at the mo but when you floor it the second one opens and efectively lets in twice as much fuel and air. its a weber 30/32 DMTE,
your asumption is right i do have a 998, full stage one with unleaded head, but before i fit the weber i want to change the cam or put 1.5.1 rollet tips or full roller rockers.

still think it will be a waste of money?

You need some 'head' action as your next port of call.

Have a look at fitting a 12G940 (1275 cyclinder head) to the car, good gains for reasonably little expense £ per HP wise.

hehehe, reminds me of the olden days when i had a Downdraught 28/36 fitted!! (ok so it was only in January).

Aye you could run a weber but it's have to be a really heavy breathing 998 i think. And that would certainyl require head work.

Also mate have you conisdered the 997 cooper cam???

[Dog]

I want a downdraught.... always have done! But can't find the one I want!!!

[Dog]

This is a proper Down Drought Weber!

[mike998]

ED4Ran, thats what mine looks like, apart from i dont have a manifold for it.
looks awsome, what engine was that on?



what lift and duration is the 997 cooper cam? where could i get one and are you suggesting i use the cam instead of the carb or with the carb?

is the 12G940 head a standard 1275 head and will it go straight on?

cheers

i don't have specs for the 997, but it'll act as a fast road cam that is driveable low down too... Keith calver swears by it his 998 engines, and i think some of the older members here will tell you how good it is too!

No the cam change would not be instead of the weber, it would go along with a modified head to make the weber worthwhile lol!

[ed4ran]

That was on a standard 998
