about how big of a shot can you run on a freshly rebuilt ls1 with arp cap screws

 

Stock pistons...?? I would say 100 shot Max with stock type pistons. Make sure you use the correct n20 & fuel jets, one range colder spark plugs, pull timing out with an MSD Box while injecting n20. You really need to upgrade your fuel system first. I would purchase & install a Racetronix fuel pump kit with the 255 LPH Fuel pump with H.D. wiring Harness upgrade & install that first. You dont wanna melt down your motor from lack of fuel pressure caused by the stock GM Fuel pump.

well im running carburated with a holley blue pump and #8 line throughout the car so i dont think that shold be a problem and ya i just dont want to spray it to much

 

Did I miss something from the OP's post?
How the hell did you come up with that list on the amount of info given?
The only thing you got right is using the correct jets.
OP, tell us what, if any mods you have done to your engine, and we will go from there.

 

No ****. I was going to say 0-300. Tell us more about the setup and we can get a closer number. But yeah damn...

 

idk its pretty much stock like bottom end wise they are speed pro pistons and arp cap screws everything else its stock

 

Regardless of the engine combo you should be able to spray up to around 200hp with no problems. You will need to make sure that you have the fueling to support the nitrous and also need to make sure you are running a good tune and the correct plugs for the nitrous in order for it all come together in a safe package.

 

i spray 150 shot, all stock 84K internals. still not even tuned after i put the headers and air/egr delete lol. dont be scared.

 

what trans? is it upgraded? we need to know more of your setup hell you could prolly spray 300 if you do it safe if your rear/trans can hold it lol

 

also i sprayed a 100 on my motor in my sig i plan on going to a 200, stock 130k mile 5.3 long block on old mild cam ls1 tune...

 

its a turbo 350 with red clutches and a stock ford 8.8 rear end

 

More info could be helpfull but as what I see a 150 should do fine make sure you have correct spark plugs and fuel system. You can just give a call to Nitrous Outlet, they do great work! They should be able to help you on what you need. Just post more info on your build.

 

well its a fresh rebuild less then 3000 miles it has new bearings rings everything like that arp rod bolts ported ls1 heads victor jr intake 750 demon msd 6010 vrx5 cam turbo 350 with red clutches less then 1000 miles on new clutches and about a 3000 stall.

 

i got a buddy that sprays 325 on a stock ls1 bottom end.. has the tune and fuel on the money tho

 

LOL! Whooohooooo!

carbed86fox, do searches for "how to read plugs with nitrous", "Nitrous Jet Spreads", "Nitrous A/F ratio", "Flowing Nitrous Fuel Pressure", "Nitrous Timing", "Nitrous Spark plugs for LS", "Nitrous Bottle Pressure", "Nitrous Bottle heaters", "Nitrous Bottle Pressure Switch" and search for threads with a similar title to to this one. The reason I threw all this out there to your straight forward question is that a good knowledge of all of the above will determine how much you can spray safely.

Are your Speed Pro pistons forged?
