I have had a lot of people asking me when they need to add an external FPR and a fuel return line - however after spending a day with tuner-extraordinaire jeff evans of Evans Tuning - EFI Tuning Specialists he let me know some interesting things i wanted to share with you guys. ** these estimations assume an equal length header turbokit and ID 1000cc injectors tuned properly
-a walbro 255 high pressure intank pump, can flow enough fuel for ~440whp on stock intank FPR, and ~500hp on a crushed FPR "Comptech Style"
-a bosch motorsports intank fuel pump, can flow enough fuel for ~480whp on stock intank FPR and ~550hp on crushed 'Comptech Style' FPR
-if you install a product called "Boost-A-Pump" mfg'd by Kenne Bell, this will jump the fuel pump's voltage supply to 20V (perfectly fine for the fuel pump, in fact good for it!) and allow the walbro to flow close to 600hp and the bosch beyond this
i hope this helps some guys realize its not absolutely necessary to add the return line and external fpr, of course for anyone looking to run 30+ psi or have a race car the FPR may prove to be a wise investment, but not at all needed for 99% of the builds out there (these cars are too damn nice to turn into drag cars anyway!)
