The Engine Build

Yes, the more fuel and air an engine can consume (generally), the more power it can produce.
If you put a blower or turbo on an engine it requires more fuel for all that additional air and you want to maintain the balance you originally had. Again, generally...putting a turbo on an otherwise stock passenger car engine isn't a great idea as MANY things have to support the engines ability to breathe.
So with breathing enhancements such as better cylinder heads, Intakes, camshafts, exhaust changes, etc. the design capacity of the stock injectors is sometimes exceeded and more fuel is required.
So in this case larger capacity injectors are required to maintain that balance.
Thanks Ronnie ,, very informative to help understand more about the processes of computer controlled fuel systems of today .. younshouldmwrite a book lol !
 
I'm getting sick of this. Both DHL and Fedex in NZ had people from somewhere else in the world and english is a second language. really hard to deal with. They have trouble putting a sentence together. I start work at 5am and finish 5-6pm most days and so can never ring anyone in those places. They drop an email at 4.30 and go home.
DHL pissed me round from 18 dec to 3rd jan. Now Fedex are doing exactly the same by people whose names I can't pronounce let alone spell.
So I had to apply for a Individual Client Code through DHL to Customs NZ. Yep no worries, all done and the Striker heads arrived. So I am registered with NZ customs. That was not a problem for 2nd shipment.
So now Fedex are having me do the same, because no one at DHL or Customs NZ has told me what my fucking number is. So these clowns can't ask Customs NZ?? So I start again another day later. This person sat on that important info until 4.05pm just before they go home. I get home at 6pm and start playing this fucking game again.
I can see why Trump wants them out. No more DEI crap. These people are not good at their jobs, why are they here??? All they do is cost us money and productivity. That just set me back another week.
 
Ok Torrie reckons injectors will be fine but should upgrade fuel pump to a 450. What are the standard OEM ones?
Does that mean a Walbro 450 in tank pump? Are they all the same?
Or is there a specific one only for our trucks?

Think of your o.e.m. injectors as a kink right at the end of your garden hose.
You have more than enough upstream flow and pressure, but...



Not much coming out of the garden hose today, as it's 27 below zero here.

A full-throttle highway test run ending at 225+ km./hr. with 69 pound injectors, 2 wideband O2 sensors and a fuel pressure gauge duct-taped to my windshield told me all I needed to know.
I can't think of a better real-world test of the entire fuel delivery system under the most demanding conditions.
Just sayin'...

Yep 600-650whp could be where I will be, so I reckon some changes should be made.
The pump for sure. Maybe sneek up a size of injector and let the better design modern tech injector with multiple holes do the job. With travel and dyno time it is a $1000 day. Probably cheaper in the long run to do it once and be right.
