Default stock cobra to 5.0L longblock and bad MPG?
How bad would the MPG be in a 99 cobra with MMR 5.0L longblock and 60lb injectors (procharged 500whp) compared to a stock block and regular injectors.
This isnt really a big factor for me, but if I use it for a DD I just want an idea of what it will be...I drive mostly city, keep it between 2K and 3K RPM, and I get on it a few times per tank...
I'm guessing it'll be around 10-12?
Any1 with a similar setup chime in please!

If that's the daily driver then I would like to see the "fun" car......

seems like in the ballpark of high teens, depending on gear ratio and how much city/highway it is

If your tuner has any kind of clue about what he is doing you should have no change in MPG. Until you get into boost of course.

I'm running close to 600rwhp and can still see 17mpg in town, and that's on a 2V

What does that mean? I had a 550rwhp 2v that was getting 18mpg just like it was when it was stock.

Again you prove you know nothing.

you don't want to drive a 400rwhp+ car as a DD, thats just stupid.

Why?


I have gotten anywhere from 7.5MPG to 24MPG depending on my driving style.
