The pump was wired through a relay , directly to the battery which was only a few feet away , since in both our cars the batteries are in the back . I also used 8 gauge music amp. wire. we were also using -10An lines and the Aeromotive filter with the 100 micron filter.

 

Well i have found my lean problem as i stated before. It was due to heat from the turbo and downpipe.

My fuel rail and injectors was at 80-85 degreece celcius wich is realy hot. Mounting a fan to blow cold air onto it works like a charm. Also my LIM has a surfaec temprature of 185 degreece celcius as well. So i need to ceramic cote my downpipe. I do have a wrapping now.

About the pump, the A1000 will not support 4x1680cc injectors at full flow. Im running a Eliminator pump now, and have just bought the pro pump, wich i will put in the car. Im not running the voltage regulator as i forgot to order it. But will the pro pump burn out fast without it? Like after 10 hours? I got a track meeting next week and i don't think summit will be able to deliver it to me before the track meeting.

Now the fuel pressure is constant. And my problem with the car going lean also happend under vacum so it can't be dropping fuel pressure. I also have a verry good voltage on my car. 14.5V constant all the time. The NSA alternator is so damn good.

Im running dual feeds from my fuel cell to the pump with the filter after the pump. And only AN -8 line to the fuel rails. But AN -8 should deliver enough fuel for 4x1680cc injectors.

Im going to increase the base fuel pressure from 2.6 bar to 3 bar, wich will give me about 15% more fuel. And then il add 2 more injectors into my excessive lim later.

Hey JT!

Im running 3bar ground pressure and injection duty was at 80%+ with 2x850 + 4x1680 @ 505whp.

Now with 6x1680cc injection duty is at 65% @ 513whp. (rich 10.5AFR)

Running a weldon 2035 pump, an12 filter pre pump, an10 filter post, an10 fuel line splitting into 2 an8 feeding the rails. An8 return to tank.
