    Right now I am still building the car and have 60 pound injectors that are going to go in. I talked to a few others and Sal ran out of fuel at the top end of a run and he is running 90's. ZZP has the 160's but if I could get away with a 120# that would work I would want to go with those. Has anyone really ran anything that large and ran into problems going out quickly?? Open to any advice!

    I'm not sure what the answer is to your question, but sal's car was 500+ at the wheels, not sure how much power you are going for.

    80's seem to get the job done.

    But without anything more than "I want 500 horsepower"...

    Your post is pretty vague.

    When I ran out of fuel I was using 80lb injectors and a Racetronix 255 pump. As mentioned I was over 500 at the wheels.

    I now have a Racetronix 485 pump and 95 lb injectors and not even close to maxing them out.

    Go with 95's. Also get the racetronix fuel pump rewire kit.

    Sweet thanks a lot for that! I thought it was your 90s you maxed.
