hey guys, i am really stumped on what is going on with my trunkmount kit. Ran 50/50 mix and am running the E1 at 23 psi. ported front and back with 650 cc inj. Custom tuned but could not go over 11.4 or so afr without getting 2-4 counts of knock. should not have to worry about that yet i dont think (at those afrs).
So, pulled the coldside pipe off with inj still installed and ran the pump. sprayed well. Then to eliminate the possibility of a weak boost signal not turning the pump and running it properly, i wired in a switch to manually turn the pump on, ran the car and still got the same results. So i know the kit is spraying when it is supposed to. Next, i upped the methanol from 50/50 to 100%. Thought my afrs would drop significantly but the y didnt. Only dropped .2 to .4 as opposed to the 50/50 mix.
Anyone have any knowledge or experiences they wanna share on this subject? Possibilities of what could be wrong? Need a bigger nozzle, obstructed line, etc? I have tested all aspects before posting as to not start a thread that would be useless or about a problem that could be easily fixed.
Help me guys.

I know we spoke on the phone quite a bit about this. Normally I would believe it was nozzle size, but a m5 is perfect for your application. If you dont find any other problem you may want to try the next size up. Since you know its flowing right, you know the spray pattern is right and you know all seems well....it would imply that you need a larger nozzle.
yeah, i am not saying that your input when we talked on the phone was not credible, i trust your judgement totally david. i am not knocking you or the kit at all. just hoped to get some info from guys running (hopefully, even though i know its a long shot) the same app and close to the same boost range to try to shed some light on my problem. Since you did reply though, do you think its odd that my afr only dropped .2-.5 with 100% meth as oppsed to 50/50 mix?
i am trying to rule out whatever i can and getthe problem fixed so the tuning can commence.
thought afr would drop more than that with 100% meth.
Thanks for all the help coolingmist and anyone else that chimes in.
I dont think anything is odd today. I have seen it all. I was not criticizing you for making a thread. The users know more than any of us. they have this car and use it every day. Getting input from other enthusiasts is very important. I did not mean to imply that I was upset, I just wanted you to know it was me that talked to you.
If all is working correctly (and this is a big if right now) you may need a larger nozzle. I am just a little stumped because the M5 should be fine for 300 HP. Unless you have more than 300 or you dont have a M5.
well david, i totally respect your opinion, but i havent dynoed yet so i cantsay what exact hp i am running. all i can say is that i am running the e1 as hard as is recommended with full bolt ons and hoping to hear form someone who has had the same experience. i went through all the trouble shooting, and like i told you today, i even wired in a switch to positively engage the pump, so i knew when i made a pull (even though i have a led for the pump current and one for the statusmonitor in the dash) that the pump fired up, still didnt get the drop in afr that i should have with 50/50 mix and especially when i ran 100 meth. only dropping .2-.5 afr from 50% meth to 100% meth is not normal. should be more. anyone wanna chime in with real data from their cars?
Just to give my .2 cents. Me and buzz been talkin online. But wanted to state what i think it is.
If afrs seem to not be stable, Or if all of a sudden you start to knock and you have not changed a thing, its 99% chance its a clog. Clogs can cause your system to losse psi, there for losse volume, can change your nozzle pattern, and cause your pump to act, pulse differently ect. a clog most likley is in your nozzle, HOW EVER i have had a check valve clog as well. They are EASY to take apart all you need is some c clip plyers. Theres a small c clip in the front of the valve, Take your plyers and go fishing for it. Theres a spring and plunger, take these out. When i did mine there was a little piece of dirt, that was stuck between the spring and plunger. There for, the plunger would get stuck shut or open or anywhere inbetween. Once clean and fixed, acted normal again. Nozzles also can be takin apart, Most of the time theres dirt around the filter, causing it to be blocked and losse psi. Clean filter take apart the brass jet andthe little ball thingy, and clean well.
IF you have a soild system no knock and good afrs, than one day you knock and afrs are all out of wack. I bet you have some dirt in your system
Buzz than told me that he JB welded his tip to his 90 degree angle, Because of boost leakin? PLEASE dont do this!!! you can not clean your nozzle if you have a clog. And you do not need to JB WELD the nozzle to the tip. If it leaks meth or boost, use Tape thread seal or liquid to seal it, That way you can get it apart

AGAIN a CLOG does not mean BLOCKED. IT will still SPRAY visibly, it looks fine, but the volume of liquid that gets into the intake will change AFRS and knock, it is VERY sensitive. I have a vari controller from a 50% duty to a 60% duty i can notice up to a .5 of afr difference. This is on a M10. So a SMALL clog will change AFRS a little, Big clog, DRASTICALLY, most of the time its VERY small clog, just enough to make your afrs change, or knock a small amount.
wow, just to set the record straight, i was informed by the powers that be that i should do the jb weld when the o ring didnt seal. i didnt wanna do it but it stopped the boost leak
shame shame. I just use teflon tape, and it sealed right up no prob. by the way dave, clutch going in so no more low duty cycles for me keep the meth 70% and higher, So gonna stick with the single nozzle. workin nice.
just fyi, i have no hard feeling towards dave for suggesting it. I am not an idiot, i knew doing that would permanently seal the nozzle to the 90. but at the time, i also knew that teflon didnt seal for some reason and the oring didnt do the trick either. It could have had something to do with the bung i was going into. im sure these methods usually work, but for some reason mine was being a bitch. I was fully aware that i would have to get another nozzle if a problem arose, so here i am, gonna give it another go round with a new nozzle. its not the end of the world. im gonna try teflon tape, liquid teflon, o ring, and anything else i can and then go from there. lol And by the way, flow monitor would be awesome, but little pricey for me right now.
another thing that might help, my pump runs fast for a second and then the line is pressured up, it starts wokring hard and slows down, im sure thats normal because it is pushing fluid out that tiny hole, just throwing it out there. pump pulses (or cycles, however you wanna say it) about once every half second
