Hi all this is my first post so here goes.
I've searched this subject on here and could find any results, if it has been covered in the past.
I've been researching just how far the fuel system has to be developed to provide good fuel delivery rates (pressure and flow volume), and at what power levels does this affect.
Threw this research it has become apparent that the main areas are fuel pump delivery flow rates, fuel filter restriction, fuel rail restriction, fuel temperature.
After emailing some of the Evo, as well as the gtr and supra lads, and looking threw there site this modification seams to yeild the best results for money and time spent.
Twin high volume fuel pumps GSS342 walbro pumps in this arrangement can do upto 500hp at 60 psi delivery pressure. Side note here, most factory OEM injectors max out and provide no further increase in delivery volume above 40psi.
High flow 5 to 10 micron fuel filter.
High flow fuel rail.
In addition this system has the safety and reliability factor of having a spare pump should 1 fail.
Has any one done this on a starlet plus info\build thread if so?. Please
Thanks sam
