race gas in dedicated or not? getting ready to spray my car (nitro dave's plate kit with cell). 99frc h/c/i/e id like to hit it with at least a 150 shot. should i run race gas in the cell or just 93? i had planned on running 110 leaded but the lead in the fuel has me concerned about my o2's.

Run race gas. That's the whole point of having a dedicated tank. your o2 sensors will be fine. the 93, nitrous and race gas are all mixing together so it wont burn out your sensors like if you ran race gas in the main tank.

Scott, I wouldn't worry about the leaded fuel and the o2's, I ran c16 in the standalone for a long time when I still used the o2's and never had a problem, just spray the damn thing already, and if ur really worried about it, put 104 unleaded in there, the race gas in the cell is just a nice bonus of added protection, but you really don't need it on such a small shot. I ran a 200 shot pulling off the rails with straight 93 for a long time with a lot more power than ur putting out, so like I said, don't worry bout it.

Race fuels will not damage the o2 sensors if you run it in a dedicated tank. 93 is being used in the main tank, which is also being injected into the motor so you will not damage the sensors. If you run leaded fuel in the main tank then you will damage them, and also run slower unless you have a proper tune for higher octane.

my plan all along was to spray 110 in the cell. when talking to someone today they said it might damage the sensors. i ran straight 110 in the cobra but i changed the o2's to a bosch sensor that the GN guys use that was supposed to be lead "tolerant". never had a problem!
i will be spraying 110.
btw dev,
im only spraying a 50 shot or so.

Actually now that I think of it, sometimes ur not ***** enough for ur own good, spraying a cobra and then a firetruck rings a bell! 
Let me know if you need any help with it, should be fun, can't wait for the 8th when Moroso opens back up so I can get the car dialed in and finally get some times with the new setup!!!

You sir have my attention! Vengeance Racing is installing a dedicated next week. I run 109 unleaded now with a 200 shot. I'll be spraying a 250 shot after next week. Would c16 make a big difference in the dedicated? I use a nitrous outlet wet plate now and I'm installing a direct port this winter. I'll be spraying 150 on the plate and then the direct port will be a 250 shot.
