    Ooo dear

     

    3rd fuel pump comes on perfectly at 4psi

    filters are all clean and way over rated for there job, I have around 1000L of fuel per hour flowing at top end at 60psi probley actually a little more

     

    injectors are clean and working perfectly, nothing gets hot

     

    :unsure: :unsure:

    surely I can not be maxing 1000cc injectors or maxing the flow rate of half inch fuel line

    :scratch:

    My mistake,thought you were burning pump 98.No need for the spray then.

    Sure you don’t have a crushed pipe or something between the tank and engine?

    only current problem is it has a wicked exhaust leak from cylinder number 8 flange to cylinder head

    And what a right pita that is.

    Hay buddy cheers

     

    its amazing what a set of wheels and some custom made manta stickers can do to it ay

     

    car is just sitting awaiting cooler temperature before I drive it again and I put 100% methanol into the meth injection system and tune that into it

     

    apart from that car runs sweet as

    Cava loved the altenzas, pretty sure he has a set now for his VR

     

    99% sure Iv maxed the injectors out, living in the tropics means it’s spastic hot at the moment so haven’t done anything yet, just driving the Monaro with ac on flat out

     

    thinking  pumpin in 100% methanol through meth injection system to see what it does

    What Meth injection system are you running?

    Thinking of using Meth injection on the missus L67 Calais.

    So i got my Bosch ev14 1000cc injectors flowed to see what they really flow

     

    50psi =840cc

    60psi = 960cc

    65psi = 1020cc

    70psi = 1080cc

    75psi = 1140cc

    80psi = 1164cc

     

    bosch say they flow these and group them into there flow groups weather it be 88lbs or 93lbs so customers get a matching set

     

    myn all had 91lbs in Nikko on them when I brought them and I have a mate with same 1000cc injectors and the part numbers match

     

    they where extremely acurate with each other pretty much bang on the same and having filters in 4 of them and not in other 4 in 1 test made no difference at all

     

    so I’m renaming them to Bosch ev14 almost 1000cc as they would only flow around 780cc at 43.5psi

     

    Up at 56-58 psi the injectors spray looks much much better then it does at 50psi

     

    my plan of attack is My pressure is 48 psi above manifold pressure so max pressure with boost is 63psi

     

    im goin to up it to 55psi above manifold pressure so at 15psi boost I have 70psi in the rail

     

    this up in pressure will make up for the 400rpm where I’m running short on fuel and also turning on the water meth with a 50/50 mix wil also give me more leave way with injector duration

     

    when I up the boost I will keep current tune and injectors as that’s more then enough for street use and more boost with 1600cc will mainly be racing use when I get to that stage

    Interesting to see the different flow rates. Were the injectors tested with gasoline or the test fluid?

    I see your looking at a 50/50 mix now instead of 100% meth.Why the change?Looking for more det control with more boost in the future?

    How’s the power to the road with the new tyres?Feel like you have got another 100 hp lol.

    Believe it was tested with 98

     

    well 100% was just a thought but after more reasherce it just seams dangerous and waiting to back fire putting my manifold hat through the bonnet

     

    50/50 just seams smarter or possibly 75% meth maybe if I’m feeling dearing lol

     

    odley enough it doesn’t feel more powerful lol, it just sticks to the road and is very deceiving now, before applying any power in 2nd or a decent amount in 3rd it would spin the tyres and that gave it a deceiving feeling of been powerfull because its just spinning tyres, now it just grips, I can get 100% throttle in 2nd now by easing power on so clearly it moves a lot quicker but it feels 1000 times safer now so it does and it doesn’t if that makes sence

    Yeh 100 % is a safety concern,although ive tested my mix and it burns’easily at 44/56 w/m which is 50/50 by weight.

    Your qtr mile time should improve out of sight with the new rubber.
