EZ-EFI on my 440 - 05/19/11 11:19 PM
Just wanted to give my opinion on the system so far. I have had it completed for a month now and am very happy. Spent considerable time and and money on the fuel lines and proper routing but other than that, the kit itself was fairly straight forward.
This is on top of an 11:1, aluminum headed 440, making around 550hp. Right away noticed great cold start and better throttle response. It still seems to be sorting out the transition between idle and cruise, but its bairly noticable. Goes lean for split second before it corrects itself, I think it still in the learning process and the weather has not allowed for a lot of driving.
I did have one problem. I, or thought I, upgraded the pump to a Mallory 5110FI. Suddenly after about 100 miles the pump had a major failure and broke internally. We had pre-filters and post filters in the system but it seems something got in there and caused an issue. Anyway, updgraded to all Aeromotive filters and had Mallory re-issue me a pump. So far so good. With this set-up at this HP it keeps up well. Only uses 70% duty cycle at 45lbs. Again still have some fine tuning. Love the product.
