Ok I have a 408 Stroker that I want to spray a 250 shot on. I have a stand alone fuel system that is going to be running low psi, like 8-10. Right now I have a 100 shot on it just run of off my fuel rail. It is an NX kit with a Shark Nozzle. I have heard that Shark Nozzles cant support over 200 hp so what would I need to do to my kit to make it be able to spray a 250 shot?

I swear these questions get asked every 10 seconds......... you did all that **** to your car but cant figure out a 250 shot........ go direct port!..... dont spray if you cant tune and cant afford to blow it up!

Damnit quit being an ***. Now I dont want to go direct port because I dont have the $1000 for it. I should be able to get a different type of nozzle or something to handle that much fuel and nitrous flow but dont know enough about it. Does someone make something that can flow that much and who is it?

did you ever think of adding another nozzle a couple t fittings and some line? running both nozzles at 125....... still gonna cost you a couple hundred bucks but for the saftey of DP I'd spend the money

I am going to the SLP-402 stroker over the winter, I am just going to spray it with a 200shot. But I am not going DP. I am going to use the NX MAF kit. Nitro daves can help you decide.

(off topic, how do you like your cam in that 408, I was going to go BIG. Also, do you think your heads are choking the motor - most 402/408 guys I see have 500+ rwhp)

I assumed, maybe thats the problem, that someone made a nozzle or something that would flow that much. So you are saying that noone makes anything like that? DP is the only way to go huh.

I like it but wish I had gone bigger, its not really that big of a cam for the motor size. I know for a fact that my heads are choking the motor. The tuner said that with a good set of 6.0 liter heads it would see 500 rwhp but I dont have the money to get them so I am stuck with them for right now.

nx makes a single nozzle that will support 400-450 hp. I believe it's called the SHO nozzle and you can find out more from nitro daves. The only way most would run a single nozzle that big is if the class called for a single nozzle set up. you could also check out upgrading your kit to a twin nozzle as stated above. plenty of people using that set up with much success.

yeah there are a few more things to worry about also. my main concern would be fuel puddling and a backfire, because our intakes werent really designed to flow fuel. also you will prolly need a bigger fuel noid. I say stick with a 200shot that should be more than enuf. maybe nitro dave will chime in im sure he will know alot more about this than me.

GueSS Who

You need alot of fuel


I have a 408 with 350 worth of bottle. It takes a **** pile of fuel. LOL

Make sure you get the fuel taken care of before you do anything with the nitrous side of things.

I have a stand alone fuel system for that. It is a low pressure regulator though, will this effect how big a fuel pill I will need? I think my pressure is onlu going to be around 10-15, atleast thats the gauge that comes with it.

I have the SHO Nozzle and it seems to work fine with a 200 shot. I have not tried it on the bigger shots but I talked to nitrous express and they said they tested it to 400hp. I think the limiting factor would be the -4an lines and the selenoids. I have the upgraded (P) selenoid that came with my kit and it is supposed to be good to 400hp. Direct port is the way to go. That will be my next route. For shots under 250-200 I think a single fogger should be fine. Make sure your separate fuel system pump is large enough to suppoer the sudden drop when the fuel selenoid opens.

The pump is a Holley Blue Pump, even though there is no blue on it anywhere at all. The guy I got it fom said it would handle a 200 shot but nothing more. Being a low pressure system will I have to put a bigger fuel jet in it to make up for it?

Nostang

Yes you will definately want to run a bigger fuel jet for a lower psi setup. I run a 78n and 62f for a 200 shot on mine @10psi fuel pressure. A Holley blue will support 200 hp no problem but the pressure is really limited to around 4-5 psi. I you run 10psi like me you should think about upgrading the pump to something bigger. Make sure you flow test the jets when setting the fuel pressure to get the flowing psi through the jet. You can use a spare fitting or nozzle for this.

$1000 for a DP kit is less then a new motor.

Sorry Im so late on this one.
The shark nozzle will flow 250 hp.It will max out at the 250.Yes they make a sho nozzle.It comes with a sho hose from the nozzle to the solenoid.It seels around the 100 dollar range.The stage 1 iceman solenoids will max out about 275-300 hp.The next step would be a propower solenoid.It is the same solenoid that comes in some of the direct ports.
What you have will work fine on a 250 shot.
If you have any questions let me know.

People have good experiances with sprayin that much through a single nozzle nitro dave? I thought it wasn't the best idea. Please enlightin me.
