850's and 1600's will do 600rwhp. Just bump up the fuel pressure

We’ve found that running the 850 secondary injectors in the primary ports doesn't work to good because they sit up to high in the modified primary fuel rail. This causes the spray pattern to get fucked up and the car will idle rich no matter what you do because of poor fuel atomization..
So, I'm running the stock 550's in the primaries to 50%, at that time it does the change over to start firing the 1680's in the secondarys, the same 2 wires are running parallel to run the other 2 720's in the primary runners for a total of 1680cc of fuel to the secondary ports and 1270cc of fuel to the primary ports for a nice balance of air and fuel.. My power fc thinks it has 2400cc injectors in the secondarys.. https://www.nopistons.com/forums/pub...#>/biggrin.png (ps. I love the datalogit) I get really good gas mileage for the size of the port I'm running and only hit a max of 19 knock according to the commander after 15+ 1.3-1.5 kgcm runs. (Did I say I love my wide band and water injection) I'm also running 2 x walboro fuel pumps with two -6 fuel lines with earls inline filters running to each fuel rail and then in to a aeroquipe fpr and one -6 return line. At 1.5 kgcm boost with the T70 I'm hitting around 78-79% on the injectors at 54 psi base fuel pressure. Now I just need to get a new wastgate spring so we can take the boost up to 1.7 or so and see what happens.. https://www.nopistons.com/forums/pub...R#>/tongue.png |

I think 1600 - 1680 injectors are the biggest commercially available. Methanol guys use 8 - 12 or more of these, if there were bigger ones available I'm sure they would use them. Keep in mind for most cars that 550 cc injectors are HUGE https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/biggrin.png

I saw 2,000cc (190 lb hr) injectors for sale somplace before fror around $80-100 or so...
|
next step, garden hose
mike |
lol.. just run in -6 hose and wire the fuel pump to the injector driver to turn it on and off... https://www.nopistons.com/forums/pub...#>/biggrin.png

how about like a cis/mechanical setup?
