Well?

 

I aim to run a 200-250 shot. But it really depends on what the numbers look like on the dyno. I will definitely tune it to be a little rich and stay on the safe side.

 

You better run a seperate fuel supply for that hit. What fuel pump are you running now?

 

looks nice, what did it run?

 

Like I said. LLLEEAAANNN...SSSPPPIIKKEEE! If you see it once don't try it agian for the sake of your motor. It just can't take 200 without enough fuel for even a second. Accumulator or not.

 

I would put alot of fuel to it to start out with and then slowly take fuel away. It will be kinda crappy to redo all of the fuel pills each time but worth it in the end.

A helper pump might be in order. I ran a 200 dry shot through a customers car for ever and ever and it did fine on a stock fuel pump in a vet but wet kits that are taking fuel from the rails is kinda risky IMO.

 

Is the lean spike inherent to DP systems in general? I thought it was just the NX NXL kit.

 

ONly if you try to pull it from the rails like that. Usually you would have a fuel system just for the nitrous on a direct port. Even then if there is not enough lead line for the n20 noid you can have a lean spike. Also if you ahve air in the fuel line (no return). I have no lean spike with mine at all drops right below 12:1 how I like it.

What kind of system are you running to get no lean spike? Stand alone fuel system I assume.

I am hoping that a booster pump along with my Racetronix Walbro 255 will be able to support a 200 shot from the rails. If not I will put in a separate fuel system.
