Indeed, the size and position of the progression holes has a significant impact on the tune and performance. Unfortunately there are not many true carb specialists left who can modify Webers, and know what they are doing. Its a black art to modify and tune Webers to truly complement the engine characteristics that they are attached to. Quote:

I got them on Yahoo actions Japan, Can look around to find some more for you if you like. Quote:

Did you have any other issues as far as e85 and it's friendliness to any particular carb internals?
One thing we found out on the dyno very quickly was the amount of e85 needed to get the A/F ratio right. About ~1 1/2 times more e85 than gasolene. I originally had F11's, F15's, F9's then F16's, All were two lean in the mid to high RPM's, Not enough volume in tube wells in order to feed the main cct. Ended up with F7's [typically alcohol use emulsion tube and have a thin emulsion tube wall thickness] and it responded accordingly. I was equally astounded with the size of main jet required also. With Short rams fitted, a 168 main worked and with the Long Ram tunes, 176 main. This is feeding an A15 [1525cc] with 14.8:1 C/R. Ernie [Bige] put me onto an alcohol fuel additive to help protect against corrosion, VP fuels upper lube. More of a precaution rather than an a requirement

Thanks very much everyone for the extra info. Benny I was aware of the 40s and 45s being different in how they hold teh chokes in (for want of a beter explanation) but didn't know which was which off the top of my head. If I'm not mistaken, the 40 dcoe 2s are sort of like the equivalent of the 45 dcoe 9s in terms of them being the pick of the litter, the best choices (for each respective size) with regards to tuneability specifically for competition stuff. I know there's some differences in the idle/transition holes on the other models, and speaking broadly the emissions ones are the ones to generally avoid.
Would it be possible to know where in Japan you sourced them from? (and in fairness I understand if it's not something you want to disclose for any reason)
If I could also enquire - with the switch to e85, was there much trouble finding a good 'match' as far as emulsion tubes go? and I'm also not expecting you do divulge precisely what ones you ended up with, just whether or not it was a big drama getting ones that worked well with e85.

Jmac, If your referring to the black ram tunes, I bought them from Japan, They are actually for Weber 45 DCOE's. I spent some time on the lathe to turn up some adapters so that I could fit them onto my 40 DCOE 2's. This particular model of DCOE require the slide in type ram tube to retain the AUX vent in position. See pics for reference. I went with these ram tubes because of two specific design features for improved performance a) the full radius bell mouth and b)the tapered bore. OEM Weber use parallel bore. cheers benny

If I could ask everyone here a question. Rather than weighing in on this to and fro, could someone who knows (I'm getting confused) please list the brand of the ones Benny pictured and how much the cost? And has anyone actually bought a set of the billet ones first discussed. I'd be curious to see how they were machined at the edges of the flange area, which would require a real up close pic in higher resolution than the pics featured in the thread.

you were going on about the Redline Weber ram tubes being a less effective design, you really had no idea what you were talking about because you hadn't even seen them.

Now a fews days later after arguing black and blue that the Redlines ones were poorly designed and more expensive, you now say you didn't realise what you were talking about, but still blasting abuse...

About giving up this was my thread sunshine and like always you have to littler it. Making things up as always about the bellmouths and your lack of vocab I brought up with your pun on the D word, you just tried to use it back due to your lack of it, you really are a sad petty pest on my threads.
