That introductory offer for the mazda head billet manifold to suit 4ag 20v itbs is cheap!

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

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. Did you have any other issues as far as e85 and it's friendliness to any particular carb internals?

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.

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

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

Australian record compression for an asphalt duty A series???
what is that beast pumping Benny?

Ernie assembled the engine earlier in the year for me. The original calculated C/R was 15.3:1, Ernie machined part of the piston crowns off to bring the C/R back to a more suitable ratio. Not sure about any sort of record though..... e85 just seems to respond well to compression and or boost or both and makes good power. As for power, it's no real record breaker. Tuning was performed on a conservative dyno by an operator who IMO can tune carbs. From memory the peak power was 117.8 rwhp @ 7850 rpm. Mid RPM power and torgue were excellent as well.

Lovely numbers Benny funny how you say to a more suitable ratio for 14.8:1 :)

Most all-motor alcohol engines have at least 14.5:1

As you said Benny, you shouldn't need the upper cyl lube. Methanol is very corrosive but ethanol isn't. Heaps of turbo cars running ethanol without that stuff.

Is it possible ethanol quality or constituents vary?
