I have a 420inline bosch race pump running out of the stock tank, braided lines up to the regulator to the rails, then returned, I have speed inc rails, and if I do go back to an N/A setup I would be around 11:1 comp 30# injectors, and would want to have a 200shot ready at all times, I would prefer to run around on pump gas.....cam would be a 240/250 nature, motor is in the sig....

Can this type of hit be pulled from the fuel system or would I be better off with a seperate cell w/unleaded race gas?

 

Anyone have any suggestions?

 

First off isn't it from the pump, are you splitting the fuel and going to the nitrous kit separately or getting the fuel after it goes through the rails?

That type of hit is possible from the tank. However your aspirations for doing a 200 shot on pump gas may leave something to be desired. I personally do not run that high on pump gas and I know Taner and Roman do not do that either. If you really want to run that big of a shot on pump gas I would spend a bit of time getting a solid detonation free tune put in the car. If not then you may want to consider a separate fuel cell that would allow you to put in higher octane fuel. Mixing of octanes is a big deal for higher horsepower cars as it promotes some premature detonation of the lower octane fuel first. But I don't think you'd be looking at power levels that this would be a problem with that you couldn't manage.

 

Ok, just as a quick hijack... for a nitrous motored car...

for shots of 200-250, would it be better to have both the gas in the tank and the seperate tank be race gas/higher octane, or would it still be ok to run a 93 octane in the tank and whatever higher octane(104/110) in the seperate fuel cell? i drive the car a ton so filling the whole tank with race gas would be pretty expensive to only get a couple passes with and use the rest on the street

It would be ideal to keep the two the same, but you don't necessarily have to. Essentially what happens, as I understand it, the two different fuel octanes will not blend together entirely. You'll have atomization of both octanes. The lower stuff will start to burn sooner then the higher stuff. Your tune has to account for that in terms of timing to avoid detonation. With straight up race gas you can get a little more aggressive on the tune. NX Recommends that you run straight race gas with their kits above 200 for this reason.

 

i see what your saying. it makes sense. race gas it is, haha

 

I currenlty run on 100, so I would probably use that all the time.......

I got speed inc rails, and a whole braided line system with a CAS regulator, so it can keep up w/the 420L pushing out back
