Default lt1 dual fogger 300shot

Well i have been spraying a 250shot on my HSW Dual fogger kit so i jetted it up to the 300shot 63-35X2 car didnt pick up any it went slower?? Seems to me like i have a restriction in the nitrous kit its a -4 feed line then -3 lines to the foggers with Zex pro selnoids,any ideas on what the restriction is im thinking the -4 feed line?

Did you have a datalogger on it??

Guys I trust tell me that is too big for a fogger on an LT1 and cylinder palance gets bad which could have resulted in substantial KR slowing you.

well just found some info the zex selnoid on the nitrous side has a .110 hole and the jets for a 250 shot is .57X2 so its .114 so it looks like i need a bigger selnoid??

I would do a bigger solenoid and -6 feed line if I were you.

-4 is good for about 250hp
-3 is good for about 150hp

You can't just add the two jet sizes together. My math is rusty but the .110 will flow more then the two .057 jets. I can look up a fomula if you want but I would up both lines like the previos two post.
