webers

[glowz]

I know, I know, I dont like them either but I gotta ask. Im a performance junkie and love the su's for their simplicity and mixture adjustment. Heres whats up, I got a slightly bored over 2.8 F54 block rotation assembly is balanced. Shaved P90 head with 10:1 and crane stage one cam and competition grind. N36 intake 70' su's with sm needles, electronic ignition, the works coil etc. It runs like a freakin beast and I love it. Does anyone think Id get some more performance form webers? IM just not to familiar with them as I've ALWAYS used su's, I've heard so much controversy I'd love to put it to an end. Anyone have dyno results? Thanks a lot. By the way I'm new here on the site and my name is glowz not because Im a dork its because I got a lime green 73' 240, under parking lot lights it actually seems to glow, ......plus..... I couldnt think of a better name, later,

Gidday GLOWZ and welcome,

IMO triples are a PITA...unless you enjoy tuning tuning tuning or are going to be driving your Z up at high revvs all day long or intend to race it. Just trying to sync them would be a ..:eek: :tapemouth You might be dissapointed with gain you may get...but that induction ""gooorup" note is ..well...like mothers milk.

Those SU's you have are great...I had twin DCOE's on a A14 engine and I was forever tuning them....maybe it was just me but I found them a big PITA.

Just my 2 pence.

i know su's are great and with the way you have your su's set up you will be fine with your application. if you ran 40 mm webers or dell ortos you would be better though. i dont know where people get a tuning night mare out of webers or the like. unless your climate is forver changing or you plan to driving it in the winter once you set them you should be good to go. bench setting the carbs is the best to do then dialing them in once on the car. it is a bit of a pain, but once there perfectly diailed and and balanced you will have a smoothe powerful machine that you will love when it takes off, especially when you fell the torque pull, and you hear all 6 barrels of those carbs open up you will never ever hear anything like it.

will you car perform better with the triples, yes it will, better then the su's, its an upgrade that if you take the time is well worth it. people like to shy away from triples saying there hard to tune and such because there either to used to the su's or just like how simple they are. i like my su's i think they are nice, but if you have a cammed engine that is bored and built to run you just can go wrong with a good set of triples.

zmefly, so with triple 40mm downdrafts there would be a performance increase to be had, is what your saying right? (for my application of course) What about doubles, I think I heard about someone with success with 45mm doubles. Anyway just wanted to clarify the identity of those webers you sudjested. thanks

[240znz]

Use 3 x DCOE Weber sidedrafts not downdrafts if you go to triples....there is no point making the fuel/air mix go though 90 degress...it would just add turbulance and that = less power delivery.

I don't think that you'd get much more out of 45 twins that you'd notice vs the SU's...goto triples if you have to change from SU's.

There is a lot more you could do other than just bolting on carbs...cam, electronic ignition...have you forgotten BRAKES...they come in handy too.

Thank you much, you answered all my questions, uhhh as for them there brakes.. yeah thats just the thing, Im sad to say they are still stock...cough. I hate me. I'll get on them sometime I swear!
