How much of a wet nitrous shot can forged 402 handle? I am using 44 lb injectors and will be installing a walboro 255 pump. Also will an flt level 4 handle a 402 with nitrous if the nitrous is used only a few times a month. My new setup makes me regret not going with a level 5

 

i think with using nitrous you MIGHT need to get a 80e

even the level 5 65e is only good for 500-550rwhp maybe 570-580rwhp and you should be up around 650rwhp with a 150shot and i would think the motor could handle more nitrous than that

 

Should be able to build it up for 300 shot if you have brass *****.

 

i would say a 300 shot is very do-able, but you will definetly need an 80e with nitrous. The huge sudden jump in torque will kill your tranny in no time.

 

the motor will most likely handle as much as your solenoids. Just guessing but most nitrous solenoids that are in the mor common(cheaper) set ups I think are only good for around a 200-250 shot. I would say your motor would hold a 200-250 all day. Just need a tranny(4l80e) and rear end to hold that. Assuming you will be able to get that much power to hook.

 

dual stage with a 150 shot each

 

On a 150 shot he will be lucky to hit 550rwhp. The truck intake and stock heads is going to kill any big number power that the shortblock is capable of. I would spray a 200 shot on it all day long, and like onebadrubi said, most kits noids are only good to 200hp anyway.

 

i was thinkin he was gettin ported heads my bad

 

dual stage... 100/150 progressively stepped in...

 

2 Stages;

1st: Out of the hole with a 75
2nd: activating mid-way through 2nd gear 125

Plenty safe, plenty of power and still good for traction purposes.

This is what my truck will see with my new engine. My supporting engine components may be a little more radical than yours though.
