do the fuel and nitrous lines have to be of same length to each cylinder? i take it, it would be better if it was? planning on building my own setup since i do know how to bend tubing, oh and what size tubing is needed? 1/4" also what grade tubing, i do have 865 or 825 tubing ( SS ) it will be installed on the FAST LSXr intake that i'll recieve tuesday ;)
we also have a big supply of tubing fittings just not the colorful ones like the dealers sell lol..
Closer in length the easier to tune but you can pill the nozzles a little different based on distance from the solenoids to make up the slight, very slight difference unless you're swapping to a carb and a huge direct system.
dont take my word on this at all, cause i definitely dont know for sure, but...
it seems to me that having the fuel lines slightly shorter would make it so theres less of a lean spike at the hit, even though thats usually not a huge issue...
The nitrous is hitting at >800psi, the fuel is hitting a 53.5 psi. Either way, the nitrous is going to move much faster.Quote:

ya, thats also some of the reason i say make the fuel line shorter, since the nitrous will obviously be traveling thru the line soo much faster than the fuel, you could try to make them get into the engine at the same time. but i think its still kinda a mute point...
No they dont all have to be the same length, go look at some of the pre made intakes on nitrous express or nitrous outlet to get a idea, i believe they will also list the size of the tubing because you can buy it seperate...or when i get home i will measure the stuff i have and let you know what size it is.Quote:

thanks guys it really helps out. i checked nitrous outlet and a few others and found some intakes setup, just wanna do the best and most effecient way and hope i dont have troubles :)
i have to disagree..Quote:

you have fun drilling and tapping every header primary to run a o2 bung in it...Quote:
