AF gauge reading

[yammi4ever]

Ok, may have found my problem with my rb3 from earlier post, I didn't get a vacuum line hooked up that needed to be. Anyway, now I am paranoid about how to read the af gauge. I already called dave once tonight, so hated to bother him at home again.

Dave says to read it at full thottle, and i am sorry, but full throttle going across a iowa soybean field with a couple waterways in it is kind of hard to read the gauge. I told dave that i was seeing numbers up to 13 14, but now am wondering if i am just seeing the numbers when i let off the throttle.

After i got the line hooked up and took it for a spin i put it on the cherry picker and opened it up a few times and don't see anything over 12.5, but is no load a proper way to see it, reading that gauge on the go is kind of a biatch. What are you guys doing.

Thanks,

If you are running race gas 12.5 is fine, I wouldn't want to see anything higher though. Running pump gas I would try and keep it down around the 11.5 range. All it takes is a quick glace at full throttle so it can be right when you start off, it doesn't have to be at top speed.

Suspending the sled and pinning it will not build proper boost. You need to be wide open under boost for at least 3 seconds and that will only happened with the sled under a load or on a dyno. The reason of course is so you know where you A/F numbers are when your motor is being taxed the most and is in the most jeopardy of having a breakdown due to bad fuel settings. I use the prologger and run logs whenever I want to see here I am at. I get back to the bottom of the hill and scroll through my log 1/10 of a second at a time to see where the A/F ratio is at compared to my boost and RPMs. The prologger is expensive $600-$700 but there are other oprions out there that will log your data and are not so expensive. In my experience my Nytro likes to be at 12.4-12.8 wide open.

Good luck
