the more base pressure behind the injector the more it will flow.injector ratings are quoted at 3 bar fuel pressure generally.the problems with increasing fuel pressure to effectly increase injector cc is that you get to the point very quickly that you mess up the spray and hence make no gains. Your better using bigger injectors and sticking to the pressure they work best at :)

600HP IS300 Turbo are running on 440cc. Something must be wrong I guess your fuel pressure is On a 6 cylinder engine you don't need as big injectors as on 4 cylinders. ;) With 440cc injects and the correct fuel system setup the engine should produce more power than the transmission can ever take. ← Different engines have different efficencys but to make a genuine 600 hp on a six cylinder you will need about 700cc injectors running 3 bar base pressure. On the one lexus turbo i mapped,I maxed out the std injectors at .55 bar at 3.5 bar base.Of course this all depends on flow of each setup as opposed to boost pressure.It also depends on how lean each tuner is willing to run the engine.Which in turn depends on what pistons etc are in the engine.

the supply problem is now cured,when the pump and line upgrade was done they didnt remove the relief valve from the tank and hence no fuel supply.Got supply and remapped to 0.55 bar before running out of fuel.To get this i had to up base pressure slightly and the injectors are maxed out,which isnt a good thing so injectors are still needed when gav gets a few quid spare. The car goes really well but by *** fiting an SM4 to this wasnt straight forward Lets see how it goes drag racing on sat now for the Crack,although the times at aghadowie do inclde reaction A.I.Autosport

The main problem with gs's car is a lack of fuel supply to the injectors and seeing as another tuning shop did the fuel line/pump upgrade its really down to them to sort out the lack of supply.Once i have it its more boost time :D

and you would be correct :)

And it finally goes and boosts :D
