.:VRsixGLI 12v R32 Turbo Build Thread

[VRsixGLI]

have you considered the surge tank from integrated engineering?? that will fit snug underneath the car for the fuel pump noise it will be one of the best options I think.

you do not want those pumps inside the car, you are going to kill yourself. the flow control valve does exactly that, and it works very well.

If i wound up running the pumps in the spare tire well I would definitely run a serious amount of sound deadening and seal the well off pretty good. That should severely cut down on noise. I have looked at integrated's pump and all I see is everyone saying how great they are but I could not find a single picture of one installed on anything let alone a mk4. I like their setups they look good but I would rather run an aeromotive pump rather than the bosch pumps. I looked around under the car several times and I could not come up with a place that looked suitable for the tank. The best place I figured to put it is where the green vacuum reservoir is located above the exhaust. Even if I put it there it would have to be custom because I do not think integrateds would fit there. The other thing I really do not like about mounting the tank under the car is if it gets ripped out from something on the road.

With this flow control valve I'm assuming there is no way to adjust the pressure without removing the trans? Is there anyone running one of these on a mk4?

Worked on relocating the monsoon amp so I can install the battery in its location. That is done I just need to extend the harness this weekend. Pics will follow this weekend. Also working on cleaning up the fuse box on top of the battery. Forgot the power cables were actually strap fuses so I either need to install inline fuses or relocated the fuse box somewhere else. Picked up a 1/2" tubing bender from grainger today and a set heat shrink kit with all different sizes to finish up some wiring. Next I'm going to set up the two relays that will go in the trunk for the water pump and fuel pump. Should also be ordering the clutch next week too. I'm most likely going to go through with that trunk setup so im probably going to get that done in a week or two as well so I'm going to be ordering some sound deadening. I really like www.secondskinaudio.com for material. Pictures this weekend.

I also would advise that you do not have your fuel pump in your spare tire well. The chance of fuel spitting out inside the car is not a good thing.
There has to be room in front of the rear end under the passenger seat
Your water tank/pump inside your car is ok tho.

[VRsixGLI]

Tank is most likely going in the tire well have not decided if the pump will be in there or not yet. Finished moving the amp. Ordered most of the items i need to delete the factory relay box that sits on top of the battery. Still slowly getting the wiring situated. Relocating the power wires to the new fuse block i purchased. I do not know where a couple of these connectors go though.

Driver side by the headlight



These two connectors come out of the waterfall.

Here is a picture of where I relocated the amp to.

Anyone running the New South Performance power gasket?

The aeromotive pumps are not good compared to the bosch. The bosch pump is a factory porsche part- engineered for reliability. It pushes into high fuel pressure, whereas the aeromotive pumps do not work well into high pressure. The aeromotive stuff or equivalent was all the rage 5-7 years ago, until everybody realized they are meant for low boost domestics- they sound like a blender and get their biggest pumps get their butt kicked by a pair of bosch.

I would absolutely not mount the surge tank in the car. No matter what fuel system you use, it will have a fuel odor if it is in the cabin. It will be loud, and lastly, it most certainly will not be NHRA legal unless you build a fire wall over the assembly.

Holy Crap!!!!! Wow!!!!

[climbingcue]

What is your plan to make the Haldex work with the 12v ECU?

[VRsixGLI]

According to Jeff Atwood its not an issue. I honestly have no clue though.

Thanks. Any insight on those connectors?

Nothing. I have mine with a 034 -10 rail and they pop right in. Pretty sure they would work fine with the regular rail given with the SP manifold.

[VRsixGLI]

Thanks for the help. How bout the injector connectors do they need to be changed?

Yes you have to get new connectors.

[VRsixGLI]

Where did you order the connectors from and are you using the purple hats for the injectors?

[joerg_]

how did you wire your pumps up? Did you make a new relay of a ignition life or just used the original fuel pump power and tap into that?

that pic is [admittedly] borrowed from another setup. R's have a big-a$$ hump in the middle of the spare well.

the fuel odor would be less concerning than the firewall necessary for a NHRA inspection. the fuel system has to be sealed for it to work right, so either it'll leak or it won't.

my build is eerily similar. different ex-mani & 3.2L being primary differences.

i think any injector larger than a 720-ish is gonna be overkill and possibly affect power negatively. your motor will handle more power than 500 whp, it's your head's ability to breathe that will hold you back. cams will allow more power. you should hold off on injectors until you sort cams and decide on a tune. (i purchased my injectors/tune together.)

as for surge-tanks....
the IE one mounts very cleanly where the factory filter ass'y is. my caR rides lower than reason allows, and i'm considering it...primarily b/c of the noise. two 044's will make more noise than an open dump [inside the car]. and you def wanna run one (if not two) 044's. the A1000 is not well-suited to your application. the 044's will handle waaaay more power more smoothly AND more reliably. if you're die-hard about setting your surge tank and pump(s) in the trunk, check out Foffa's setup. it's very clean. you may also consider (as i am) a falsie to hide them in....like the air-riders do to hide pumps or tanks...something you can hide the equipment in, insulate for sound, but also open for access to your bits w/o having all your junk out and open in your trunk.

i have to assume you'll be running twin, open dumps. (if no, WTH are you doing all this work to make power?)

i look forward to this build coming to fruition as mine does. (i have a self-imposed March deadline for driving my R again)

hit me up anytime, and good luck.

(i purchased my injectors/tune together.)

The head is fully built with over sized valves and 263 cams so there isn't really anything to sort. I only planned to run the ID1000's because there have been quite a few people having very good success with them. I agree they may be overkill but I haven't put much research into them. When I talked with Bill Schimmel he suggested to run Bosch 950s so I figured since the ID1000's were tested to supposedly out perform the bosch 950s that they would be a good move. As far as a tune I don't plan on buying an off the shelf tune so I shouldn't have to match injectors to a tune.

Everything would definitely be mounted in the well and concealed under a false floor with sound deadening all around. I would be clean like everything else I wouldn't throw it all in there. I am not set on having it in the trunk it just seemed like the best bet since I really am afraid of ripping the tank out from under the car. I would love to run IE's setup since it would be so easy but I have yet to see a picture one installed. All I continue to read is how great they are but not a single installed picture. If they fit right where the factory filter is I will most likely be purchasing one. I would also most likely run the dual setup.

i have to assume you'll be running twin, open dumps. (if no, WTH are you doing all this work to make power?)

I did some research about this and pretty much concluded there was not much power to be had with running open dumps or recirculated gates other than an extreme increase in noise?

I am 100% with you on the march deadline

If you check out the pictures where I ran the battery cable you can see the other wire I ran for a 12v switched to wire the pumps. Since the battery is in the trunk I will be using the switch wired with a relay for the pumps to pull power right from the battery.
That is not my picture.

I have no hats. Just the injector.

not to mention running open dump will throw off your 02 readings, so not the best idea for tuning your standalone. it also really does sounds like ass...

[charlie hayes]

Would you care to explain how an open dump will mess up o2 readings on standalone? If you tuned for it, I see no problem. Most of the times when you recirculate the dump its after the o2 also.

[obdONE]

usually the dump tube pipes back into the DP just above the o2 sensor. I know on mine, the o2 sensor is 3" below where my dump tube comes back into the DP:



Allowing the dumped gasses and the turbo gasses to flow past the 02 sensor will just give the standalone that much more information to read, and allow you to more accurately fine tune your AFR targets.

obviously people do and have run open dump with success for a long time, so I'm not saying "you can't do that", "it won't work". Just for the best possible results, it's better to recirculate it back into the DP.

if my explanation doesn't do it for you, well then just stick to the fact that it sounds like ass.

Wiring sucks

[GTijoejoe]

haha. touche.

But your "fact" is an opinion.

hahaha

but seriously his opinion has a very logical theoretic background. It must prove that the exhaust gas is not uniform, which shouldn't be hard to comprehend.
One 02 sensor takes the average mixture from all cylinders, we understand that not all cylinders have the same mixutre, especially from something like a VR x-flow head. (ie. its been shown on super high HP vr's one of the back cylinders is always first to go, most likely from fueling).
Than understanding where your WG is actually positioned, on many cast mani VR's its always on the corner, its logical to undertand that the flow gated from that port will have a higher percentage of exhaust gas from the closest cylinders, if its dumped than the average 02 reading is from the larger percentage of the remaining cylinders......

If you have a collector type manifold, gating off the collector should keep you closer to the true overall average among all cylinders.....

IMO

thanks for backing me up, brother

however, Charlie was commenting on me saying that it was a "fact" that open dump sounds like shi_t, not that my explanation of why running open dump would throw off o2 readings.

[TBT-Syncro]

open dump has ZERO effect on 02 readings.

the sensor is measuring ratio, not volume.

What I was going to get at but I didn't want to screw up this thread with a crazy debate or fight. I have never heard of an open dump causing problems with anything except for the opinions whether it sounds bad or good.

[obdONE]

I'm not here to fight either or mess up this thread. I'm very excited to see the end result!

I have heard both arguments and rationals as to why one is better and vice versa. At the end of the day I'm sure the OP will be happy with whatever he chooses because it will be what he chooses.

Back on track!

[GTijoejoe]

A ratio from a percent of that whole = not 100% perfect... come on you know this

[huichox4]

A ratio from a percent of that whole = not 100% perfect... come on you know this

look at the tip of your sensor, that's the only part that picks up exhaust gases, the rest that goes around it it goes not measured, the gases are well mixed by all the turbulence created while collecting in the exhaust manifold and when going through the turbine wheel and no other gas, air, nor anything is being introduced to the system so an open dump reading is just as good as a recirculated one. on a better note your wastegate opens when full boost is reached which for the most part it will remain closed(boost dependent).

open dump is better because it also reduces pressure from the exhaust, when the gases are re introduced they will create even more turbulence which is not ideal once the gases are flowing after the turbine. if you don't like the noise you could muffle it somehow.

[VRsixGLI]

Figured out what the connectors were. The two larger connectors are supposed to go together except the 12v harness has an early style connector and the R32 body harness has a newer style connector. So I had to go the junk yard to day. Found the newer style plug from a 2.0. Had to buy some repair wires from the dealer to repin the connector. Now my buddy has been helping me trace through wiring diagrams from the 12v and R32 to line up the color codes to solder on the new plug. VERY FUN. Wiring is almost complete. Once that is done its smooth sailing.

Transmission has been completely disassembled for new syncros and shift forks.

Moving slowly along.
