Just wondering what peoples thoughts are on these injectors, they sound pretty good and should be able large enough if I decide to go E85
These high impedance Bosh based injectors are a 48mm long body, a shorter than normal injectors. They have been modified to flow 1,000cc and use adapters to make them "normal" 60mm length and adapt them to 11mm or 14mm orings. These have a droplet size comparable to a 600cc Siemens injector and way better spray pattern and atomization than any other 1000cc injector on the market. The proper battery comp values are also provided with each set so you can set it up in your computer and have consistent a/f ratios as battery voltage fluctuates. Since these are High Impedance, there is no need for injector drivers or injector resistors.
High pressure capability, All injectors will run comfortably at 100psi above 10v, flow will be increased by approximately 50% at 100psi
High duty cycle, with a recovery time of only 1ms, all injectors will run up to 92.5% duty cycle at 9k rpm and 95% duty cycle at 6k rpm while maintaining linearity within 1%
Excellent low pulse width response, linearity within 2% all the way down to 2ms, predictable response down to 1.5ms. Using a 3 dimensional battery comp table with Motec V3 software, low pulse width response can be linearized to practically zero flow
Good atomization, Droplet size of the 1000cc injector is comparable to the Siemens Mototron 60lb injector, and is far better than the Multec 95lb, Standard Motor Products (RC) 1000cc and Siemens 72 and 83lb injectors.
Excellent consistency, no sets will require more than a 1% trim
These injectors are sold in matched sets by both flow and injector dead time. Matching the injectors based on both dead time and flow results in a difference 1% from minimum to maximum pulse width. If you don't match the injectors based on dead time, you can easily end up with a 4-10% flow variance from injector to injector in the 2-3 ms range, where most of the life of the injector is spent. This can have a huge affect on idle quality and how smooth the engine runs.
2JZ fuel systems (HKS rail excluded) will require the 14mm spacer (purple). We have run these injectors on multiple customer cars with rave results. For those needing additional fuel beyond 1,000cc the Hypertune intake manifold combined with dual fuel rails will offer you plenty of fuel without sacrificing drivability. For Porsche and some European applications these injectors are a drop in upgrade and just require the clips to be swapped.
what was it you observed that made you want to use that amount of differential pressure?
