well, i just finished my v2 supercharger install tonight at about 2:00. did a little beginning testing and found that the car was stalling every time i popped the clutch. we took a look and realized the charge piping had poped off where i had neglected to tighten it. but anyway, the car is now loud as H*** and im thinkin about getting a different muffler just to quiet her. im gonna do some more testing tomorrow and make sure everything is running correctly and do the finishing touches on part placement etc. i have a question for anyone knowledgeable in boost. how can i tell if the car is running lean and that maybe i installed the fmu incorrectly for some reason (you never know). i have an egt gauge and im assuming that the higher the egt temp the leaner it is. ive got to wire that and the boost gauge up tommorow. i just dont want to permenantly damage something so im going to take it easy with her for a while and keep careful eye on things. any suggestions on this would be great as i am a newbie to this stuff. thanks!

 

good luck man and congrats.

 

Honestly man if your fmu fuel lines aren't hooked up correctly your car wouldn't start(trust me i had this problem). The only thing you should worry about is the vacc line that goes on top of the fmu. Just make sure it has a good vacc source and you should be good to go and let her ripp. What pulley are you running?

 

Nice Job with the install.

I have a mechanical fuel pressure gauge that sits under my hood most of the time, and I duck tape it to my window for testing occasionally just to be sure my pressure is rising. If the pressure is going up, you're good to go. Mechanical pressure gauges are cheap at auto supply stores.

Otherwise, yes if the EGT gauge is rising rapidly before you get to around redline, then you "may" be lean.

 

You can use the EGT guage but things can still mess up. My initial tune was done with an auto meter A/F guage that was not a wide band. Once it was on the dyno my a$$ tune was almost perfect. Just make sure the EGT don't get above 1200deg F until you have a chance to get an accurate A/F reading.
I took my FMU off a few weeks ago but if memory serves the barb going str8 down goes to the tank side of the fuel tank return line , the barb on the side goes to the FPR side of the fuel return line and the nipple on the top tee's off the vaccuum line attached to the FPR. I'll see if I can't get a confirmation on that.

 

aww man you guys are so lucky being boosted. i only rode in a mx-6 turbo once and didn't really get on it cause i couldn't drive stick well enough. but that thing had me againt the seat in 1st gear then i grinded 2nd and said i hope i didn't break nuthing. . i have to have a turbo by next summer after i read up on it and save some money. nice modd by the way i know you love it.

 

Hey Mximus, look in the stickies under thread links, at the bottom there is a link that tells how to tune with EGT.

 

nice sig, 7200rpms at 0mph

 

I'll trade you for an n/a..Just kidding, happy boosting.

 

thanks.i had the car in neutral or park one or the other

 

ok quick question guys. my car is idling really low like...400 rpms and i cant figure out how to raise the idle. they say to adjust the bypass skrew on the iacv..problem is i dont know what the iacv looks like or where the skrew is and the hanes manual i have it not very helpful. ive looked in the stickies too and found something on it but it was kind of vauge as well.
As for an update on the sc, either a belt of pulley is squeaking and driving me nuts so ive gotta figure out where that is comming from and fix it. ive also got to connect the boost gauge so that i can see the boost im running because i have a suspicion that right now the bov is just venting most of my boost pressure. right now im only using the 7psi pulley but ill go on to the 11 or 13 psi one sometime next year. first ive gotta get aquainted and work the bugs out of this setup. thanks for any info you guys give me!

 

the iacv is next to the throttle body. it has a bunch of colored plugs on it.

 

Just because your boosted doesnt mean you cant check the Stickies...

yeah like i just said, i did read the stickies and couldnt find what i was looking for. i also did a search. but thanks for the thread.

 

this is all i see: How to adjust IACV -

Warm the engine up to operating temp.
Turn off the engine.
Disconnect the TPS.
Start the engine and adjust the idle speed using the stop screw on the throttle body to 650 RPM's.
Turn off the engine.
Reconnect the TPS and restart the engine.

If the IACV is working correctly your idle should be correct. If it's a bit low, try adjusting the screw on the IACV bypass to get your idle speed to ~700 in neutral with no load. (no load means no lights or A/C)

this is exactly the thread i found and it seems kinda vauge for me, maybe im not looking at the right thing but, ill take a look and see what i can deduce.

 

The IACV is to the upper right of the throttle body and has like 4 colored plugs in it (mostly grey and purple in color if I remember correctly). There is a black plastic phillips head screw on top which is the IACV bypass. Don't touch the bypass yet if you're going to adjust your idle. Adjust it from the stop screw on the TB first (you will have to loosen the locknut before you'll be able to turn it). If you still can't find it let me know and I'll take pics for you

 

ok thanks, yeah i ended up taking another look and found it and in the dark (for some reason i didnt notice it in the day). i did notice the skrew on the throttle body and played with that for a while but didnt see any change so i gave up on that. anyway, i got the idle working at least, the boost gauge hooked up and the sqeak gone because i had the belt to tight. now comes a somewhat larger problem. I have come to find that half of the vac lines going to my engine are showing absolutely no vaccume at idle which im assuming is a little messed up. i have a mevi and the only vac line i can see that is working is the one going to the mevi which is creating constant vacuum. so i tried hooking that one up and leaving out the mevi for a while but that did nothing but make a constant vacuum. so my current problem is working out which vac lines need to be connected in order to get a proper vac signal while still allowing the mevi to work right. also, hooked up the way that the instructions told me, the car would slowly go to about 12 or 14 psi of vac and stay there under moderate throttle (i was expecting boost psi). so clearly now im a little confused and will have to take a careful look at this situation because my bov is not working with the current no vacuum set up. i know this is basically one long run on but hopefully some of you guys might have some idea of what i can try to look at for solutions. thanks for the help and support.

 

i also forgot to mention, the idle is also fluctuating constantly. the maf is plugged in so im kinda guessing that this is also a vac line problem.

 

I will try to help but your explanation is a bit confusing.

Thre are several places you can tap for a vacuum source for either your MEVI or boost gauge. I am guessing the lines you say have no vacuum are just simply not vacuum lines because if they were not showing any vacuum at idle then your car would not be running. One that will work for sure is the fuel pressure regulator vacuum line and another is right off the manifold next to the IACV. The one off the manifold is different for an I30 but I know it is a good vacuum source on both I30's and Maximas.

When you were testing to see if you got a boost reading were you just reving the car at idle, because that won't put you in boost. Obvously things are different with a turbo and SC set up, but moderate throttle will not take me out of vacuum.

 

ok, that helps to know. the only thing i can think of that im doing wrong is i have misidentified the fpr for something else and installed the vac line for the sc in the wrong place, because at idle, where i believe the fpr is, i am getting no vacuum through the line. ill try the one off the manifold as well (i think i know of that one because it ended up without a connection while i was installing it and ended up connecting it to the 5 way splitter anyway. all i know is that the vac line for the mevi is working well, and seems to be the only one working. i have a few other suspicions as well which i will check in on. i know its got to be something simple. thanks for the help though, i guess i would have to take it out for a run to see any boost pressure. and sorry for being some vauge and confusing....im a newbie at boost still and im kinda takin the crash course all at once. needless to say, its a little confusing for me. thanks again!

 

just an update, i took a look at the directions again and found several things that i messed up, so im gonna sort those out and see how it works then. it should be an easy fix.

 

Yeah, and what is really scary is he did it before his car was even fully warmed up!

 

Congrats on the install!!!
Just out of curiosity... Did you do the install yourself? How long did it take you?
Thanks,
Mike

 

I didn't even notice that. Ouch
