Least then when you want more power in the future you one step ahead... And you will want more power ... we all do... Get ready to start buying the misses gifts to hide all the mods you been buying.

Later ran an 11.8 @ 116mph which translates to a weight shifted power of in excess of 600HP or 450KW.

As others have said, it will work but it’s not safe. You don’t want your engine leaning out. The dyno graph shows the fuel pressure steady until about 296kw then just leans out. Tuner left it at 290 until I upgraded. Some cars a freaks though and will make 330 with a stock pump. Better off getting one. I decided to leave the stock one and go with an 044 and surge tank under the bonnet. Sounds awesome when it’s running. I’ve even had someone say there’s something wrong with my car Link to comment https://www.fordxr6turbo.com/forum/topic/66908-what-is-the-best-recomended-fuel-pump-to-run-with-300rwkw/page/2/#findComment-991411 Share on other sites More sharing options...
