well. i finally got a BUNG on. so the fun begins. not bad, cost 25 to get one welded on. so for those who wants to use the wide band for the tech day we are going to have. it will be easier if you get one on yours also. dates will be posted in a couple days. so wish me luck on tuning this big ass holley.

Best of luck tuning that pig in. Who welded it, horsepower connection?

no, went to hawks prairie automotive. they were open, close, and was able to do it today.



so far i've got mid 12's to low 13's wide open in third.

best part is i got my nitrous low to mis 11's. what a difference.



not sure exactly where i should be, thinkin of trying to get it in the mid to low 12's n/a . does that sound right?

NA you want mid to high 13's for most power. to be safe with the NO2 you should stay mid-low 12's

I would not go any higher than a 13.5 na, on the same token rotarys tend to be happy running rich So 12.5-13.5 probably would be the range for wot. Sounds like your on the right track. Let us know.

i still need to weld the bung onto my down pipe im lazy hahah maybe u could do that for me on the tech day?? https://www.nopistons.com/forums/pub...R#>/tongue.gif

12.5-13.3ish is safe n/a wise...turbo i like to be anywhere from 12-12.5 at WOT. Realistically, you should be able to just unthread the o2 that is underneath the car that mainly reads how the cat is doing and throw the wideband o2 sensor in there for a few, and then swap them back out.

yeah, but if you do that without being able to hook the wideband to your ecu the car will not know how to run.

the majority of OBD1 cars only use the factory o2 for mainly emissions... Not a whole lot of fuel maps or closed loop goes on. But it is more accurate welding on another bung im sure, or throwing it in the tail pipe..but thats hard with cars like mine with duals, and factory exhaust

yeah i dont HAVE to weld another bung in i can remove the old one... but i wanted to have both in and see what was going on... and position the wide band at the end of hte downpipe so it wont be taking quite as much heat... rotarys like to burn up sensors fast
