Where do you guys have your timing set at for the spray? 100-150 wet shot.???

I had my ride tuned.

Stock would be ok as long as your A/F ratio is good.
I would recommend a change of plugs to a heat range cooler than stock and NO platinum bullshit!!

i put new plugs in, but am having issues w/ the car bogging down bad before the launch when it's sprayed, ive taken off the sol and tested each one and the jets are right,so im just wondering if it has something to do w/ the timing.

What kind of kit are you running....? Is it a plate or are you spraying before the T/B?
Also is your car a auto or stick?
When you say it boggs is it revving slowly or does it fall on it's face and then pick back up?

Also are the lines on the solenoids to the plate or nozzel the same length?

Do you have any idea where your timing is at or what the total is?

Did you gap the plugs to the "stock" setting?

Usually when tuning a car with nitrous you pull 3-4* of timing out of it. Sounds like the gap may be off a little on the plugs. Could be blowing the spark out. Or maybe have a shorter fuel line causing you to go rich, that would cause you to bog.

I run stock tables and get minimal KR, maybe 1 time every 4 pulls - probably just wheel vibrations or other driveline getting shocked when it hits (it always occurs RIGHT when the juice hits). Stock timing should be fine... but you can pull some out if you really want to.

Staggering the line lengths are done to soften the intial hit. Sorry but the 1000 psi of bottle pressure has volocity that exceeds your 50 some pounds of fuel pressure.
That small delay is NOT going to cause a bog unless you have a 36" on the fuel and a 6" on the nitrous side.
If timing is stock 2 degrees is plenty. 4 would cause it to react pretty lazy on the motor for everyday driving.

I forgot the specs on the plugs but I did the research and set the plugs to whatever the gap was... As of right now, the car is at stock timing, I havent gotten it tuned yet, was just gonna sit on it untill I got it tuned but thought I would ask. As far as the system goes, it has a TB spacer block with two ports for the fuel and nitrous, as when i say it bogs down, it falls on its face for a second or two, then you can feel the extra power kick in, i realize it's not like the movies and such but the intial stall sorta kills the fun.
