It also appears my yellow spring was on the low end of the scale. My max boost on spring was .46bar ~ 6.8lbs

Joepro · 04-26-2014, 07:46 AM

this is correct, that is tuned on the wastegates only, I cano contact vince and find out what the true baseline is.

jwick · 04-26-2014, 07:50 AM

That's cool. I got a range of what it should make on spring and DJ for my comparison needs.

My Stillen exhaust is more restrictive. Bottom line I'm making more low end torque compared to top end whp.

Trq > hp anyway

How does everyone's scavenge pump sound? How long did you guys idle/drive before the cement mixer noise subsided?

jwick · 04-26-2014, 10:36 AM

It never does. Nice thing is you'll always know its working

09nismo498 · 04-27-2014, 03:45 PM

The quietest it will get is when its pumping oil. Once the bumper goes back on, it is barely noticeable. And about the hot start issue... I haven't had a chance to drive it yet because I haven't got my leaky oil fitting replaced yet, but I had it idling in the garage and when you shut it off and restart it, It starts a little rough. Not that bad though, didn't need to give it throttle or anything. I figured it was the tune like jlo said

its the only way people know something is up with my ride LOL

Boosted Performance · 04-27-2014, 06:30 PM

The pump will make noise when the engine is off since it is not pumping any oil. As the gears brake vacuum you will hear it. When the car is on, and oil is moving through, the pump is rather quiet.

I had tested a pumps function a long time ago and I set it up to move oil from one bucket to another...the pump just hums where there is a full load of oil going through it, but when it is just a trickle, it will make noise. Just not enough oil in the gear housing.

TopgunZ · 04-28-2014, 10:59 AM

Well my build has tested me. I had less problems twin charging my 350z..lol.

Upon first start up I had E85 literally pouring out of my exhaust. After figuring out it was my injector on cylinder 2 that was stuck wide open and I had them cleaned. Then a ticking/tapping noise appeared. The noise can also be heard from under the car rather well like its coming from the intake filter.

I had a buddy come listen to it and we both agreed it sounded like a bent valve. We suspected my ID1000 dumped so much fuel that it hydrolocked that cylinder and tried to compress the fuel, which doesn't compress.

I went and purchased a leak down tester and all cylinders tested under 10% loss. So it isn't a bent valve. It doesn't sound at all like a knock so I'm not concerned about it being a rod. The sound is hard to pinpoint as it comes from the entire plenum.

I first used a paper towel roll to listen around the bay but couldn't figure it out. Then bought a mechanics stethoscope and still cant figure it out.

I am thinking it may be an oiling issue at this point and may be a lifter or all lifters not getting properly lubricated.

Thinking this because I had to drain all 7 quarts of my full synthetic oil since there was fuel in it due to the cylinder filling with it then leaking past the rings into the pan. The second time I filled it "when the noise started" I only put 4 quarts in, in case the injector was still bad I didn't want to ruin another full 7 quarts. But maybe by only putting 4 quarts in, it wasn't able to properly lubricate everything. I now have 7 quarts in but the noise is still there.

Ive also heard that if a damper goes bad it can make this noise.

I think the noise has calmed down a bit but now after listening to everything for so long I don't know what I am hearing anymore. Maybe this sound was always there but with the engine cover off and the hood closed always when running it was just muffled.

Also, my car idles really rough from the base map and this may be a totally different situation since I had a new base map made for my setup vs. the original map everyone else has.

Any suggestions?

m3chhawk · 04-28-2014, 11:03 AM

Knocking noise - Maybe the valve train is beginning to get lubricated again after being 3 qts shy and that is why the noise is going away? Keep in mind these valve trains are rather noisy as is.

Did you get all of the old fuel out before going E85? What is your idle AFR? If you don't have a wideband, just log using UpRev and check the OEM sensor readings.

TopgunZ · 04-28-2014, 11:08 AM

Its not a knocking. Its definitely a ticking/tapping/Loud clicking noise that increases with revs though. Its not my injector solenoids either as I know what those sound like and are just a quiet clicking. It actually sounds like an injector if the sound was magnified by 20x though.

I did get all old fuel out. I think. I sucked it clean with a wet shopvac. I hooked the vac up to the in tank line and tried sucking everything over from the drivers side but not much came out. Maybe that could be an idle issue.

My wideband is connected post turbo in the 3 inch downpipe and reads super lean. Im seeing it bounce from 15.8 up to 18. My OEM pre cat sensors are reading fine though. I am using a tablet and Bluetooth OBDII to read that.

If I give it enough gas it puffs smoke out the tailpipes. Maybe I should dump another 5 gallons of E85 in to ensure Im on the E and not on what that drivers side possibly had in it.

Did you put your stethoscope on the injectors? I know that the after market injectors are loud, and they do tick. When I first installed some 550cc injectors I thought I did something wrong, as the ticking was very noticeable. So I poked around forever trying to figure out where the noise is coming from...and I found the source of the ticking by accident, when the stethoscope made accidental contact wit the fuel rail.

The base map is custom for your ID1000's so the car def. needs to be tuned.

I did and they all make the same sound level clicking noise. The tapping noise is constant and on the same beat as a single injector would be so if it were loud injectors then it would be a very fast rhythm as all would be going off. That's why it sounds cylinder specific.

Also, I didn't notice this when these same injectors were in my 350z.

I did put in an 8lb spring in the BOV instead of the 11 that came with the kit. Now it holds it fully open at idle. My reasoning being that on my 350 the 11 lb was too strong and I had stupid surge at anything besides full boost. But I think I have stronger vacuum on the 370.

Anyone getting the flutter sound at half boost on the original bov spring?

I wouldn't go in to boost on that map till it is tuned.

The slight flutter is normal.

TopgunZ · 04-28-2014, 11:49 AM

Yeah It hasn't even left the jackstands yet. Right now it has no plenum or plugs.

I know the flutter is ok and normal. I just dont like it. Sounds like crap when it does that. Some people like it and try for it. To each their own. I just hope the amount of air coming in isnt creating some weird vortech in the intake pipes and throwing my MAF's off.

Ill probably pick up the spring between this and the 11lb one.
