Default 408ci Directport

well Im about to finish my directport w/steel lines and im not sure what shot to begin with because i havent sprayed on this motor b 4..the motor has already like 8k on it so its really broken it already... any advice.. by the way i have a stand alone for the n20, and i will be using the maximizer to adjust how hard the kit hits.. by the way this is a nx directport with two noids. what do you guys think, 100, 150,175, 200, 225 or 250 shot. my kit jumps from a 150 shot to a 200shot i was leaning towards a 200 shot..

I would start with the 150/200 then check everything out then move on up.

I agree. 150 is a good starting point for a DP.

1st off, check your plugs, make sure your tune up is good and your fuel psi is on.
then go threw, be sure you hook, adjust suspention accordingly, be sure everything looks good.
after a few track runs, when you get a few minits do a compresson test or leak down on the motor just for safty.
lots of things need to be done. biggest thing is plugs. be sure your not lean or melting them, timming is right ect ect.

If your using high pressure on the standalone fuel system then i would go less then the .014 fuel and .024 nitrous. I think its about a 180 shot. anything smaller on the fuel jet and your asking for trouble. IMHO

When I think "check" I am referring to A/F ratio. This will let you know everything is working fine. Doing a large shot and not knowing your A/F is risky to me. That's just me. After I know my A/F is good, (or if not why) then other things fall in line to check. I personally record a 3rd gear hit with my LM-1 and see where I am at. This gives me a 5 second run under good load and I can see if my fuel pressure is set correctly and the system is working well. This also takes traction out of the equation and gives a nice run.

if you know how, reading a plug is the most accurat way to tune.
the af monitors are good, but plugs dont lie. lol

I wish I could read plugs like that! Not enough experince doing it that way on my part. Would probably be a good "sticky" with pics and descriptions.

i know what im looking at, but to try to explain, that would be hard to do.
i know what to looks at, but different setups change.
some may need more fuel by jet, or fuel pressure, ect ect ect.
i think some one did it one time, it wasnt 100% correct, but real close.
the right way todo it, is do a pass, as soon as you pass the traps, shut the car right off, roll off the track, pull over and pull a couple plugs. thats the most accurate ay

I voted 250, I'd tune for the biggest shot you'll go to in the future, then back it down if you want.

I went with 225 with 250 as a goal but lots of dyno time and plug pulling to check the tune. Esp with the 408. A 150 shot on a 408 will not cut it for you i'd bet.
