Re: Fuel rail back pressure

on the road it is awesome however with the vitara centres and the rock hopper transfer it screams through the gears really quick. i have played a little on some boulders and i can feel the difference but have not really had a good wheel yet. it runs sweet, all really clean, smooth through the range ...

Re: Fuel rail back pressure

you are correct MPI is the way to go however i am on a strict budget. no offence but this is my first ZOOK and you guys are mad, which i suppose makes me even more insane. i came from an 80 series running 37 and hilux running 35's to a Zook on 33's having said that the thing is TOO TOO much fun. (i ...

Re: Fuel rail back pressure

hi guys sorry for the no reply i really do appreciate all this time and knowledge being shared. firstly there us buckets of fuel being returned to the tank so volume/flow is not the issue. yes i have a rising rate regulator with a gauge attached which i took to work today and checked for calibration ...

Re: Fuel rail back pressure

sorry by the engine combo i think you mean G16B tbi and the turbo is a single from a nissan GTR twin setup. before i restricted the fuel return i was not able to get it over around 2500 before detonation (lean miss) the timing and plugs helped but the regulator on the fuel return got me to 4500 rpm ...

Re: Fuel rail back pressure

i appreciate that the pump can "only " do 250 hp i am pretty sure i am nowhere near that. But i ask you this! if the pump can supply an rb30 (3000cc) at 7psi at 6000 rpm why can it not supply a 1598cc at 6psi at 4500 rpm? one more thing and i hate to correct you but the correct term is "PINKING" it ...

Re: Fuel rail back pressure

Re: Fuel rail back pressure

It is a definite cough (total loss of power). it only happens if i really stab it, gentle acceleration is fine. have changed the plugs not the timing and what air lines are you referring to as there is only a MAP connected and i figured it needed to be there. what timing should i be running? I ...

Fuel rail back pressure

Fuel rail back pressure how much is too much? i have recently turbo'd my G16B single point injection and to get rid of the lean miss up high i have installed a pressure regulator on the return line to the tank, the reg is running the fuel px at 60 psi. I am only running 6 psi boost and it is still ...
