So what do you guys think? How much nitrous would you safely try and push with 104 unleaded if everything (plugs, a/f, timing) looks good. Thanks.

i run nothing less than 116 in any nitrous motor.... if its taking 2 big kits then 118... easier to tune.... with a fuel that has alot less octane the tune has to be right on or you start nipping pistons.

Thanks for the advice, but I'm talking more on the line of a street/strip set-up. I'm looking to see how much hp I can push on the single stage plate. You see guys all the time running 150-175rwhp shots on 93 octane. So maybe a 200-225rwhp shot is ok on some 104?

the plate systems are more or less restricted by the distributuion of the plate itself. Most guys don't go over a 200 for a reason= bad distribution. I haven't had the nitrous outlet dual stage in my hands so I can't comment on that one. But if you are runnign a single stage I would keep it at 200 or less.

There are a lot of other variable involved with your set up- like how much timing you are throwing at it. 24 compared to 27-30 will make a big difference in how big of a shot you can get away with with 104 octane.

Thanks, but I mentioned I will try and have all the bases covered, timing, plugs, A/F. And I'm not saying it won't be a little risky, but Nitro Daves plate is a real nice piece (not just a hunk of metal with 2 nozzles stuck in it, or a spray bar shooting to the back of the manifold) and others are already past the 200rwhp mark with it. I would just like to know the limits of 104 unleaded.

why not try vp109 for the 200shot?

ya, how come your sticking with 104? easiest attainable? i was running 110 w/ a 225 on my old mustang

Unleaded is why, I don't want to screw up the O2 sensors.

i knew a buddy of mine sprayn 200 with his car a unleaded race fuel with o2 sensors and never had a problem.....

VP109 IS UNLEADED! i have been using it to compare to 104 and 93sunnoco. the reason: to spray the 200w as safely as possible and also so that when i do spray the 200w i'll be closer to my target afr of 12.2., i don't have a roll bar to keep making passes to tune, so if i get kicked out, maybe it will be as close to max tune as i can.

Thanks for the info on the VP, I really don't know much about racing fuels as you can see. I asked about the 104 because that is the only unleaded I can get at the track.
