I dont think you can ever completely tune out some bog. You should have no bleed back get a 00 jet so it shoots te whole wad lol. I dunno if there is a way to lengthen the throw on the squirter or not. but if you look at it with the cover off it only works till 3rd throttle. If you could lengthen the throw and increase the level in the holding that would be good. I have done this on nikkis buy bending the throw rod and adding shims to the chamber to increase capacity.

I too am getting some unknown noise that i also think is guide related. Took my valve cover off today and noticed some slight wear on the guide. Chocking mine up to stretched chain. Only does it on mine at the magic rpm of 1350.

All i can say is FAWK! i have seen Apex seals fly out the muffler but never this.

no domestics???? i bought a 08 grand prix bullet proof good mileage decent looks. tons of interior space. i got it for 14 out the door with 19,xxx on the clock. Mazda 3 dude just go back there slamming cars. Hell go for a 6

I think rpm is irrelevant as to when the mains come online. I think it has to do more with when there is sufficient vacuum/air flow. Keep in mind idle and main overlap and need to be paired accordingly. Remember if you are past the ports you are drawing fuel from idle and main circuit. The main is not gonna be emulsified and be more like droplets causing rough running. As per the conversation i think 80 percent of your issues is that box. Airflow is so choked off its not even funny. Seeing as that box has probably no design thought behind it. Who is to say all your flow is not going to 123 or 245 or whatever. Like i said when i was using my hks turbo plenum for a cold air box before the turbo., flow was so hindered it was a struggle to get above 5 grand. It was fine to a point but just fell flat after 3 grand or so. Hell close your idle mixture screws off at see what it does. Bet it dies

Pilots are idle jets in webers and do overlap into mains. Pending where the progression ports are aligned with the throttle blades they affect well up into the high 3'000 range. I was hoping he would call. I am curious as to how he has it idling at 1,500 what means to a end to get it there. Because if he did it with the throttle stops screws and is in front of the 3rd progression hole that explains alot.

I sent a pm with my Phone number give me a call mark. I am also a firm non believer of air boxes on triples. Hinders low end performance something fierce.

Its gonna be diffrent somewhat for you you have a big ol stroker. I would love to actually drive these cars to see what everyone calls a stumble. Sure if you mean i crack the throttle to much at 1,500 grand it goes flat on its face than yeah thats gonna happen no matter what. Or if you mean it was fine then it went pop and lean backed or bogged for a second and i did not vary my peddle and it picked back up fine, type of deal.

The funny thing is i can remove my hks box run N/A all day with my afr's pulling hard as a mutha at 10.00 or even 9.00's Dont believe me i just so happen to have the face of the box off and can go make a pull to proove it. You are only really rich between 3,700 and 4 grand. The engine is pulling so much vacuum right there that you would not feel that rich spot. The motor is turning so high that its getting burned off jsut fine. When i had Su's i was pulling down 11's wot on the gauge. I think you are basing carb afr's off efi afr. 12's and high 11's are not rich not at all and in fact should be richer. Remember maximum torque is made while rich max hp is made while slightly lean. I helped someone over the phone a week ago dial in his 40's easy peasy no flat spots no dead spots. The fact of the matter is you should be able to tune a set of triples and pretty much be able to move them to any L6 with very small tweaks needed. The afr gauge isssue is your call your motor. But to say i dont want to get one casue it does not match my other gauges......thats actually kinda ricer would you not say. I know your not but thats the mentality.

Every stumble i have ever encountered in triples is because of a lean spot not a rich spot. Your theory of bigger cam etc etc would make the rich factor negate itself. How could you be so rich if you dont have enough vacuum to pull the fuel from the carb. Air moves faster than fuel hence the progression ports and circuit. I dont think you have enough air volume at say 1,400 to draw that much fuel out of the ports to be that rich. I set mine up at 11 for afrs steady so that when the tip in occurs its getting into the 12 but buy the time it get to high 12s i can watch on my wideband where the main circuit is coming on. It slowly goes back down in a liner fashion too the 11's. When it was N/A i had the idle set to the 10's. At first i had it at 12.7 but i had issues between idle and main circuit. So i plopped in a bigger idle. Backed the screws out 1/2 turn got my idle at 10.5 or so and the stumble went away.

really dude i have read the whole thread months ago. I am telling you what worked for me and several other webers i have setup. Your narrow band tells you nothing absolutely nothing. Not trying to be combative but you gotta ditch that thing. Saying you dont want to buy one cause it does not match the other gauges is kinda silly. Aem makes a very good unit sub 200 bucks and its responsive as hell. Hell i am even running boost threw my triples now and i can punch it at 800 rpm and it takes off like a mutha. You need a wideband spending money on jets for trial and error is well error. If i can tune a blow through weber setup to be perfectly linear than N/A should not be a issue. I dont seem to understand why so many people are having such a issue. If the progression ports are setup fine and the idle is setup fine there should not be a stumble. How do you know your overly rich? You have no data to back this up other than a setup that can read 0-1volts

I would increase the idle jet really to surpass the stumble. I would also back out the mixture screws more to richen up the idle to compensate for the stumble.

You really need a wideband man. All the money on jets and no feedback really. I cant stress enough i never had a flat spot ever. When i set mine up i dialed it in at high 11's that way Buy the time the transition came in it was about 12.3 for a split second before the mains cam online.

Hows about that Zx dizzy.

Updates: Well i was having some issues with my carbies over the last week. They got torn down and rebuilt today. Got my idle tuned in to 13.7-13.5 steady. I also went up on my jets from 145 to 165 today. What a difference. 11.5 WOT car saw 125 in 4th gear for the first time today. In a hurry i might ad. I have also added a stag 2 snow performance methanol kit to the car and am pleased to say it works fantastic. Not only does it cool my intake charge down a ton it drops my afr's down to 10.8-11.2. As a added bonus i get a nice steady blue flame coming from the tailpipe when it comes on at 10psi. Bad side affect trans tunnel gets a lot hotter. I have turned the boost up to 18psi which i think is the max i can run for right now. I must say i believe i am way over 400 now. My goal for tomorrow is to buy a scanner get my first dyno sheet scanned in and go back on friday for another pull. I might put off the second session though as i am going to secure a megajolt and a edis setup. With this i should be able to do all sorts of evil things My goal in all this is to see how far i can push a N/A zx block. I must say i am more than pleased with the outcome and drive-ability of this system. Again its not better than efi but it is better than the stock efi i am sure. When you look under my hood its a frankenstein of old meets new. Its truly a site to see. 18psi is a hoot and i cant wait to see what i lay down for numbers. 20psi is in the future but in order for me to push it that far its gonna need to be on the dyno. Gas mileage has sunk to a all new low with a estimated mpg at wot around 4mpg. Gotta pay to play.

Nice

Very nice i was looking at there gps speedo yesterday. I wanna do it but i dont wanna pull the dash:(

Indeed thanks for posting that.

Chokes are the inner diameter sleeve inserted before the aux venturi. Webers don't have chokes like a normal CHOKE. They have cold starting devices. Which is what you are not running.

I test drove a ms 6 all wheel drive 260hp it was fun.

Sucks to see......insurance.....mazdaspeed mazda 3 time?????

a chevy scoop on a z hood.

FWIW my best lean idle on my 40's is 11.5 and it stinks to high heaven So bad when the ol' Lady comes out to talk to me i just start the car and count the seconds till she leaves. I love it. I love polluting. I love rotaries. I love lime jelly. I love playboy. I love running threw the streets naked smoking a cigar covered in lime jelly reading playboy.......oh wait this is not a Dennis Leary special.

what size exhaust.
