Nitrous plumbing A1A...??..

Ok so you have an efficient motor, I personally think iron heads make more power myself but thats another thread. You say your Eddy kit is now a max of 100hp?....thats hardly worth all this effort/$$$ to me but I guess you gotta start somewhere. Perhaps going to the retard boxes is the best way for you and if you do that I would do a 150 shot min to get any real "beat your buddy" results, 100 shot run real lean on the fuel jet could work ok as well.
