Once setup they shouldn't need maintaining either. *n eerrr.. well not quite. Once the jetting has been set up(jet sizes and needle size/position)this will not change but the balance will between each of the carbs. This would of been done at the time the jetting/needle sizes were selected and the balance needs to be checked over a period of time to make sure each of the carbs are opening exactly at the same time. You will need four seperate vaccuum gauges to read the vaccuum from the four carbs,one of the carbs will be fixed(one of the middle two carbs)and you balance the other three to that one. Makes a differance to the slow running and rev pickup if there out. One other thing Ive noticed on these conversions is the lack of air filters,especially air filter boxes. Ive found that some bikes run like sh1t and lose the bottom end power until an airbox is fitted.Its due to the way the air enters the "constant velocity" carbs, they don't seem to like what they call "dirty air"and prefer the controlled air entry from an air box. If youve got any issues with low end pickup try an airbox......

R1 carbs would be reet, you'll just need to find the correct jetting!

Does anyone know if bike carbs would make more of a gain on say the standard injection of a 16v BMW 318is M42 engine? I did ask on the previous page but no answer. The engine would totally stock except the addition of bike carbs and the additional systems to run spark etc, with standard injection the engine would be about 134-140BHP.
People seem to get good results with XEs on bike carbs, and this is another 4cyl 16v. I don't know anything about XEs, but I presume people are ditching injection on favour of bike carbs.

It's a case of which flows more rather than injection vs carbs get the area/size of the injection body (or the most restrictive point in the manifold) and compare it to the area of the four bike carbs, add a little in favor of the more accurate fueling of individual carbs and bing! theres your answer.
A guy on the ppc forum said he used 51mm ID coolant hose from Pirtek as the hoses for mateing the carbs to manifold.

Here's mine. Not carbs but injection on a 1400 Suzuki Swift engine (fitted in a Mk4 Escort rally car). farm3.static.flickr.com/2323/2316565882_bbae1b17ff_m.jpgfarm4.static.flickr.com/3215/2315757005_fde099544a_m.jpgThis is running MBE management. To give you and idea of the question you had on power, I was initially running the Swift (actually Cultus Gti) plenum chamber with the MBE system. It was putting out 132 bhp. When I fitted the throttle bodies the peak power was still the same at 132bhp but the torque was much better all the way through the rev range so it made a big difference to acceleration.

Are the carbs steadied by anything or just held by the rubber hoses? They seem a bit heavy to hang too far out. Was wondering this recently as well

Does anyone know what bike carbs would suit an '80 Renault 12 (R.1179), fitted with a 1397cc (Type 847) engine?

what ive done is just used the edis control module from an earlier mk5 escort. They ran a single carb on the cvh engined cars but still had a ford edis.
Rigged it up to webers before aswell. Its always worked a charm and given good results on the rollers.
PM me if you want a set up cos ive got loads. They come with looms and wiring diagrams.

Mmmmm interesting to know, at college the second years are working on some autograss buggies. The are using 1.8 and 1.6 zetec e's but using CVH manifolds and carbs using adaptor plates and keeping the coil pack. Will the later edis modual not work with carbs?

I think you will probably get a small gain, but not worth it for the output you're putting into it... But if you do do it, let me know 'cos my BM's got the same engine and it'd be nice to see if there's any way of getting decent power from it!
