my friends im running a 71HTA with a DW301(nice pump BTW) with full exhaust 1200CC injecs running E100 and i cant get fuel after 1.1bar of boost, added tons of fuel inside map and no way... i really doubt the DW301 is not holding , i already did 400whp with this pump in a STi and E100, so my guess is whats the limits of the stock FPR?? i think it cant handle the flow and is getting me there...



please thanks for anyfeedback!

 

I would check the pump and make sure its good. I recall hearing that some of those pumps had issues.

I had no issues pushing well beyond 500whp on the stock fpr with a double pumper and 2150cc injectors. Something else is most likely the issue.

 

I made over 630whp with ethanol and the OEM regulator. The regulator could have gone bad, or you could have lost the line to the regulator from the intake manifold. The pump could also be at fault.

 

Check to see if your overrunning it/and or if its working. You do have a fp gauge?

 

thanks guys, im gonna change FPR tomorrow and see what happen, will set the 4 bar in the FPR.

dw is brand new, really dont believe its not working well...

 

A fuel pressure gauge would answer your question.
