bike carbs on my 8v.....

wud it be a big job to do  ?
im thinking about a set of R1 or gsxr carbs for my clipper 8v in place of my single weber carb  just cus i want a bit more poke out if it…

wud it be worth it if i got the correct parts etc and a manifold made…

any advice etc wud be helpful    or any one who has done this conversion…  how did it go etc..

cheers

The main problem with the 8V is that the inlet manifold is above the exhaust manifold. That means that heatsoak from the exhaust warms the inlet mani up (and any carbs sitting on it), thus reducing the mass of air you can get into the engine. So you're kinda chasing your tail with mods, the GTI gets round this by getting the air to come from the side.

As far as the specifics, I imagine the manifold would be the biggest obstacle to overcome. If you can fabricate one yourself, then it should be okay, otherwise its going to be costly, for not a lot of gain.

ar right

so even if  i heat wrapped my zaust and had a direct air feed on to the carbs it wud still make not much of a difference?

im looking to get more power out of my engine…  and im just after tips and advice really as to the best things to do to them..

i know alot of people go for twin carbs and say there the dogs danglys  etc  so im just trying to find out the best things for what i cud do..

cheers for your help too!

new r1's are injected. and old ones ran down draft carbs. best bet is a set from a yam xj1300 with enlarged jets. but as already said lots of cash for not much gain. you would get a nice induction noise from them though.

if you really want to go down that route look for a set of mikuni carbs

as already stated, not worth the cost/effort for the bhp gain.

Try a weber manifold from rallydesign, they fit jenveys and many more  (this is what i have used) With a little bit of fabrication you'd get bike carbs on them i recon. I'll Pm you some info if you like but it is expensive.

cheers for all your advice.

so would my best rout to get more power and performance etc.. be to head down the twin 40/45 road…

the only reason i thought about the bike carbs was because of the huge price difference in them and weber 45's etc.  
but knowing now they wont make much a of a difference on power  i dont think i'll bover.

and yeh mates  some PM'd info wud be appreciated just so i got a few idea's.

thanks again.

Take a step back, forget about what specific hardware you shoul dbe purchasing, and answer the following questions:

- How much money do I have?
- How much technical skill (are you putting it on yourself or getting the work done for you)?
- What do you want to achieve? ie what's the car to be used for.

money- not a problem
skill - not a problem ( my old man and his mate have over 60 years experience between them )
and its use..

its my everyday road car. but i want to give it that bit more poke under the bonnet and tune it up abit, make it look a bit tidier than a standard engine as im hoping to start showing it etc once ive done more to it ..

or am i being silly ?

Don't know if its silly - but I can't see the point of modifying an engine for looks reasons. I can understand you'd want it neat and tidy, but I'd be doing some kind of work and making it as neat as possible, rather than considering it as the prime reason.

If money's no object, then 20vT is probably the most sensible route. Everything is available off the shelf, and its a good amount of power for a Mk1 to have a lot of fun with!

bike carbs are hard to get set up as u have 4 carbs to tune, they are held onto the manifold with silicone hose and you have to build a few brackets up to bolt them to the engine to keep them still as they pop off the silicone hoses when u boot it as the thrrottle cable pulls them of, i done the bike carb route on a 1300gt engine in a mk1 not that much of a gain a bugger to start in the cold mornings. only good thing about them was the noise they produced amazing!. but this could be achieved with carbs. like paul said if moneys no object then there is a whole load of conversions u cud do. g60, 16valve turbo, 20valve turbo etc etc

its been thought about many times for a complete engine conversion either a 1.8 t or a abf 2.0   but  as im still fairly young ( 19 )  my dads not really liking the idea of it all being on his insurance too which is quite annoying really.

i might just go for twin carbs etc as im sure he'll help me out with that being as hes had them all before on his old cars etc so i can just say im carrying on his tradition and hope he agreee's haha


thanks alot for all your advice etc.
