Need Big Shot Help

[99gsr01]

No I just have 93 in the fuel cell and 93 in the tank also. I don't use race fuel yet.

your quote: "are you saying that you run the motor on your stock tank and have your dedicated nitrous fuel pump pulling race gas out of a seperate tank for jsut when you spray?"
I just thought that was how it worked...

ok..well..you need to run more octane..with tha thigh of a shot 93 isnt enough...and no..thats not generally how it works..top fuel and funny car will warm the car up on methanol alone, then they will activate the pump for the nitromethane..but thats a different story

Higher octane fuel will help alleviate the problem. Check to make sure your getting proper pressure on the nitrous feed for the fuel, if it is running low that is your problem - of course your fuel filter for the nitrous fuel pump could be a little plugged up too.

I was messing with the fuel pressure regulator last night and it had some blockage in it. It was a bee or bug head that was cloggin it up.
It looked like it was clogging it up pretty good I pulled it out and I will try this again... i bet that was the problem..

the fuel cell has dedicated line to just the fuel solenoid, right? If so, filling that cell with 107 octane or such would be a good idea, especially going to a 300 shot. This will help you engine resist detonation when the nitrous is going. (and if you wind up not needing the race gas, just use the 93 octane, to be sure you get enough fuel)

sry for resurrecting this, didn't notice it was old, my bad.

93 octane wouldnt be enough..even if 107 was too much..there is several octanes between 107 and 93 that he would want to try first..plus he could even mix 107 and 93 and depending on the ratio he would be between it..you could run gallons of 93 though that motor and it wouldnt be enough to prevent it from detonating

well, the octane wasn't set in stone. I'm no octane expert and i was just using the number i saw earlier in this thread, it was more of a proof on concept on the plumbing. That concept is solid, isn't it (I think it sounds good, but I might be missing something)

[VTECsqznN2O]

his build and ideas have blown motor written all over it...but we'll see

[96HALX]

probably not the most effective setup, but hopefully it will do good for him. (it sounded like he was doing alright in getting the kinks sorted out on the last update)
