Trackhawk fuel pumps vs E85 mods/performance
I would like to discuss fuel pump requirements for Trackhawks that have been modified to use E85. Assume that the build has upper and lower pulleys (~18 psi of boost), ID1300 fuel injectors and all other necessary mods as required for proper use of E85.
It is my understanding the dual fuel pumps in Trackhawks (TH) are the same fuel pumps installed in the high horsepower Dodge Redeye and Demon. They each produce 450lph for a total of 900lph. (If this is wrong, please correct my statement.) I also understand that E85 performance packages (e.g. Livernois 1025S) available to us produce around 850 whp and use the stock fuel pumps safely. I also saw a post that +1000Hp TH's are using the stock TH fuel pumps.
At what point should a build consider switching, for example, to a 3 pump system? I personally would like to get close to the 800Hp range on a properly built TH and need to know if new fuel pumps are required. Thanks for any feedback.
