How do u choose the right nozzle size?
from research that i have done i have heard between 8-12" before tb and then the second one 6" before that one
anywhere between the ic and the tb is the ideal location though and they say the further back u place it away from the tb the better the atomization for an more even distribution between the cylinders
Ok good because the one I have is about a foot away from the throttle body. I just have to get a better system that activates faster. If I do a pull from low rpm to redline Im fine but a pull from 4k or higher and it knocks.
Are you down shifting or rolling in? Does this happen everytime or after a run if you try again does it go away? I would also look at the timing in those given load/rpm cells. Make sure that the transition is not to severe.
Rolling in. Yes I happens every time I roll into it from a higher rpm. I do have a check valve. I do log my pulls just no sure what you mean about the transition being to severe. My timing doesn't increase or decrease more than 3 at a time if that's what you mean.
I do recommend it. For me advancing both intake and exhaust helped for my cams. I found that it brought out some mid range and did not lose any up top. I am going to do some back to back runs once my car gets back from the body shop. I had someone bump me and mess up my paint.

I don't think that you should need that much jetting
. You will have to multiply by your IDC and unless your tuner knows how much that might be it could be hard to figure out right now. I will try to estimate it as well. Post up some math if you get a chance. Sorry I can't remeber how much it was but Jeff can help you out.

1450x1.1=1595
1595/3=532
532 in the 130-140psi pump range is 1.0mm at least from what i got and the reason for the bigger injectors is because of what i have now and the block that im having built. having a 2.4 longrod built and a huge turbo going on my build that should put me over 600whp so thats why the big injectors. what i have now on high boost with the meth should put me over 500whp..... lmk
Here is what I came up with at 70% IDC. I don't think that you will get that high though, depending on the turbo. With the gain set to 1:1 you would need a lot for sure but another thing to remember is that if you can add up to 50% IDC through the gain function. So I think that two 1mm jets will do the job. Scaled up so that the jets just reach 99% at redline they would be flowing about 1050cc at 130psi line pressure give or take a little.
With 4 1450cc injectors = 5800cc at 70% IDC = 4060cc aiming for 25% gives us 1015cc.

Man that is what I am saving up for... A LR 2.4 and a 3586. It seems that the turbo will just keep me under the wtq people have started to say tears up our trannys.
You mentioned something about going larger turbo. In that event, You may need to get jet happy. Which turbo?

i just bought a trans off of evokid03 on here with an evo 9 1st that he had done to handle his car that was nearly 700whp. i got that and a triple plate exedy which i think im going to end up trading for a twin and the turbo im looking at is an agp zeta 3.2 dbb .63ar capable of 700whp with full spool around 4k but the 2.4 motor should help some with that

not sure yet letting jeff figure all that out with what i told him about my build and agp turbos are mostly run by srt 4 guys..only reason i looked at them was because the turbo on my car now is an agp that the previous owner had put on and the new turbo will be a direct swap...its based off the garrett gt35r
