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.

thats always a bummer man...im running hks 272's right now so wasnt sure..when i asked my tuner he said i shouldnt need them yet. also how much did your meth tank cost? its awesome.. my tuner said to go ahead and step up to 1450cc fic bluemax injectors and doing the nozzle calculation for that and 100% denatured alcohol that he wants me to run puts me at 3x1.0mm nozzles!? if this is the case my whole uicp is gonna be fitted with nozzles lol...im actually talking to howerton and they are some nice and smart people so he is helping me with my build and quoting me on a tank and set-up

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.

1450x4=5800
5800x25%=1450
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 asked jeff from howerton and he also said i would need 3x1.0mm jets so guess thats what i will be doing while he helps me build my kit

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

Well I trust Jeff. Are you going to use the multiport bar for spliting off for the three jets? I have never heard of that turbo.

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
