Plate setup + 200 shot on stock LS1?

Plate setup + 200 shot on stock LS1? I'm wanting to run a 200 shot but i'm 50/50 on this still. I've seen a lot of guys getting away with it and it got me wanting to try it myself. I've been spraying 150 for about 2 years or so with no problems at all. I just ditched the single nozzle for a Nitrous Outlet 78mm plate.
Some of my questions are:
is it safe to pull that much fuel off the rail for a 200 shot?
with the msd timing tuner how much timing would i need to run?
would it be better to run race gas when spraying this much or regular 92 octane?
and what other mods should i do with the fuel and/or motor?
I'm open to all comments.

As long as you have the fueling capable of supporting the 200hp shot then you can pull it of fthe rail with no problems
with the msd timing tuner how much timing would i need to run?
IT will depend on what your timing is at right now as to how much you need to pull but for the 200hp shot you will need to pull at least 8* from stock timing. If you have already pulled timing out for the 150hp shot then you wont need to pull 8* of timing from that.
would it be better to run race gas when spraying this much or regular 92 octane?It would be better to mix some race gas in there. If you can get it i'd suggest at least getting some 106 octane but 110octane would be better.
and what other mods should i do with the fuel and/or motor?
If you haven't already upgraded the fuel pump in the car then you mihgt want to thinnk about doing so to go tot he 200hp shot. In your sig it says you make 495hp ( I'm assuming on the nitrous ) and if you are on the stock pump your already at the limits of the system. Also on the plug you will need to be running a BR7EF ( will be fine for 200hp ) or a BR8EF ( Will be on the lines of a bit safer plug ) in the car.

With no cam in the car he should be ok with the factory injectors. It would all depend on what the injector duty cycle is at right now. If it was a dry kit then Yes he would definitely need to upgrade. We have several customers spraying 200hp hits with factory injectors. He might need them but it's a toss up. Every car does react differently on nitrous.

If the car is good without nitrous. If running a wet kit you wouldn't need to upgrade injectors to run any size shot of nitrous correct!? Dry shot would obviously be a different story but wet the injector is irrelevant when spraying a wet shot.
This is as much of a question as a statement.

Chris, yes i am still on the stock fuel pump and everything else with the fuel system is stock. Would it be recommended to upgrade the rails along with the pump?
Also the 495hp is with the nitrous, N/A it put down 342/355 and if i recall the injector duty cycle was 88% on the most recent N/A pull on the dyno. I also haven't pulled any timing for the 150 shot but thats why i have recently purchased the timing tuner because i know i need to. I'm going to be dynoing tomorrow with the nitrous and i'll see what the duty cycle is. I also have been running TR6's

I have a pretty good size cam which I had to upgrade injectors when I installed the cam. $ for $ I went with 42# injectors. I can now spray a 150 shot with a 232/246 .615 cam w/ LS6 topend and my duty cycle is still low enough where i can still grow. And a fuel pump will be a necessity! My duty cycle was at 45% on motor and just under 60% with a wet 150

If you have the money to spend i would upgrade the rails at the same time. If not then the factory rails will support the 200hp shot with no problems.

I would suggest more than just a pump upgrade....Go with the Racetronix fuel pump/harness kit. Best $250 you will spend on the car, a fuel system is not the area to look for the cheapest parts. It comes with a new wiring harness for the fuel pump, this will provide for a more stable current flow to the pump.
Also as stated before there should be no reason to upgrade the injectors just because you are changing jets in the (wet) nitrous kit.

I've been looking at the Racetronix fuel pump/harness kit. Is it a pretty easy install?

With the stock pump i woulnd't try it but if you have upgraded the fuel pump then it can be done but the tune needs to be spot on and you need to have the correct spark plugs in it.
Fuel/ Tune/ Plugs spot on then i'd say go for it. ( But you do need to know at that hp level with the stock internals if something were to go wrong it will more than likely cost you a motor!!! )

Back when I was on my stock motor I ran the TNT F2 kit jetted for 200. I had a cam and bolt ons and a walbro 255. Ran the 200 for two and a half years with no problems. And that was at least 2 bottles a week.
