Re-working my car for a little more power with an E85 conversion and could use some help on fuel injector selection. Under consideration from initial research are the Injector Dynamics 1050cc EV14 and Deatschwerks 550cc EV14 injectors.

The car has a BP-4W engine with Rotex C15-60 supercharger running 60psi regulated fuel pressure on 93 octane pump gas. It is currently using RX-8 yellow-body injectors (420cc) and producing 210 RWHP with max 80% duty cycle. I doubt they would be up to the task of providing sufficient flow for E85. The target power level is just a little higher at 225 RWHP. The car will be used in NASA TT4 competition, so I do not need to make any more power than this.

I've read that the ID1050s are the go-to solution as they are a superior design and idle smoothly even on engines with much lower output than they can support. Please let me know if there are other (better) solutions and your thoughts and suggestions.

 

I use the ID 1050x on my 1990 E85 turbo 1.8 swap and it's all good. ID is the best because they provide accurate injector data.

 

I use flow force 640s on my 240whp Rotrex NB running E85.
same EV14 tech as IDs, Cheaper option than IDs and seem perfectly up to the task..

 

Take a look at the snake eater performance injectors if you want to potentially save some change. I just switched to the sep1500cc injectors and am still dialing them in, but pleased so far. The 1500's would be much too large for what you want to do, but they do offer smaller ones as well.
