Ok, I'm gonna run a direct port shot on a forged rotating assembly. What I have yet to figure out, is when do you say [edit] the stock fuel system and start running your fuel from a seperate cell? I am thinking of running a 200 shot at first, but I will probably bump it up to 300 eventually. It's a wet shot. So will the stock fuel rails hold up to it (with a 255 in tank pump, or maybe two?) or is a seperate fuel cell needed? and any any basic information on running a seperate fuel cell would be nice too (do you treat it like a fuel tank? just throw a fuel pump in it and run a braided line to the solenoid?)

This isn't really a HP issue. When you run a seperate fuel system with a wet kit you do so in order to use expensive racing fuel on the wet side without having to actually fill your entire tank with it.

Partially true. That is one of the big reasons for going standalone but remember the fuel pump has to support the total HP amount. So if he was spraying a 300 shot on top of a 450 HP motor the pump would have to support 750 HP. That's a sumped tank and external FP territory, which might be fine on a all out race car but not the ideal set up for something that might see some street time. That's where a stand alone can come in real handy too, why run a large pump if you don't have to?

My racetronix harness is already pre-wired for a second fuel pump, but my question is where do most people mount the aux fuel cell and pump for a system like this? Anyone have pics?

Matt -
Good point.

I mean, obviously you need more fuel, which is why I upgraded my pump & injectors for my dry system. In fact, I think I bought one of those things from YOU.

I think I got the kit from Dave, the pump from you and the injectors from racetronix.

Anyway, you're obviously correct. I just never think about it because it's just background stuff to me. Like, "I'm gonna need wheels for those tires..."

allright, hate to play the dumb car enthuisiast guy, but I wanna make sure I got this down right, before I mess something up.

the car is a dd, so it seems a standalone is the way to go for me, I don't really want to put up with the sound of an in-line fuel pump on the street. what would I wire the fuel pump to? the window switch for the nitrous, a seperate window switch to kick on a few hundred rpms lower then when the nitrous kicks in, or the arming switch (or would that put too much pressure on the return line?)?

and who makes a standalone fuel system for an lt-1 camaro (namely a 97). I looked on Harris Speed Works and only saw a kit for ls-1's? Does it still fit an lt-1, can I make it fit with a little fabrication, or do you plan on making an lt-1 system in the near future (5 months)?

sorry for all the stupid inane questions, but I'm new to this standalone fuel system stuff.

HarrisSpeedWorks

Usually we suggest wiring the pump up to the arming toggle switch. Our cells have a return line on them so there is no problem with letting them run for a little while. Our LS1 kit could work on a LT1 with a little fabrication, the air intake track would be the deciding factor on how difficult it would be. We do have a LT1 system in the works though.

allright then, i feel edumicated now. Looks like I'll try to wait for the lt-1 system to come out, since my engine won't even be done by aug-sept, hopefully the fuel system will be done by then.

aaaannndd since it was brought up, i might as well ask this instead of making a thread 2 months from now about it. any rules of thumb about what kind of race fuel to run when using a standalone?

Like Harris mentioned, I liked a standalone fuel system because it allowed me to run a 100 shot on a 12 second car with stock fuel lines/gas tank in my 3rdgen. I had a pump gas motor, so I could buy 1 gallon of 110, stick it in the fuel cell, drive around on cheap gas and spray with the good stuff .
