Just talked to Wayne at RC Engineering about the injectors I just sent to be cleaned and balanced; good info was received! Based on their knowledge, the 380cc injectors were good to about 300 HP, 440cc size to about 360 HP and 550cc injectors would be needed to go above that. This assumes all other factors needed are in place and injectors are figured at 80% duty cycle. Finally some info to help guide us towards specific HP goals that we can plan for. BTW, Adam at I-Speed will be converting my manifold to parallel from series fuel feed next week and pictures will be taken. I`ll then send them to Josh to be hosted. Once this is done, the balance of my engine will be ready for install and break-in. Again, my thanks to Joel at PDM for holding me up for 4 months and not returning my money At least the rest of you won`t make the same mistake I did and can use reputable people. Enough for now----Rod
