TGV's, hardware, and gaskets: 2590 grams

[IMG]http://i162.photobucket.com/albums/t278/RasmusHansen/SubaruParts/IMG_4671.jpg[/IMG]
Intake Manifold: 3404 grams I had to weight the three seperately because it maxed out my scale (>5kg). But altogether the OEM intake/tgv system weighs 5994 grams. Almost 6 kg.

[IMG]http://i162.photobucket.com/albums/t278/RasmusHansen/SubaruParts/IMG_4696.jpg[/IMG]
Reduced mine to 4310 grams. Saved [B]1684 grams[/B]. Those are Grimmspeed phenolic spacers epoxied to the bottom.

Installed it all. It runs, well. Nice pickup in acceleration too.

I didn't know that was a concern for EVAP delete. I didn't monitor for mileage loss. Is that just a rumor? Why would you lose mileage? What's the reasoning?

[quote=68Cadillac;36364581]I didn't know that was a concern for EVAP delete. I didn't monitor for mileage loss. Is that just a rumor? Why would you lose mileage? What's the reasoning?[/quote]

Because evaporated fuel just gets vented to atmosphere instead of being burned.


I've given up weighing every little thing I've taken off my car, because it's hard to do delta-weights (i.e. remove 3lbs of wiring, put in 1lbs of wiring, 2 lbs delta). I'll weigh my car when I'm at a happy plateau.

Current projects include:
Removing carpet and painting floor pan
Another wiring overhaul
Removing fog lights
Removing heater core (pretty much only drive the car in the summer anyway)
Shaving intake manifold
Decomplicating throttle body (that's a trademarked term ;))

The ECU doesn't lessen the amount of fuel fed to the injectors based on what's coming in from the EVAP charcoal canister. The ECU doesn't even know how much is coming in from the EVAP system. Plus it's only cylinder [B]1[/B] that gets any of the EVAP fuel vapors. I hypothesize that the car (e.i. cylinder 1) would run [U]slightly[/U] richer with the EVAP intact. Delete it and the mileage would stay unchanged according to my hypothesis.

I'm just saying that's the theory, not that I subscribe to it.

[quote=Splinter;36364722]Another wiring overhaul[/quote]
I'm going to look in to this. It really did suprise me how much mass was in the sub-harness attached to the intake manifold. I've got wires everywhere that don't connect to anything anymore because of the amount of systems I've removed.

Examples:
Fog Lights
Cruise Control
Daytime Running Lights
EVAP All the way back
TGV on the Main Harness
PCV detection on the Main Harness
Splinter 02-12-2012 11:56 PM

Just be careful. A lot of wires are joined mid-harness and you might think you're cutting out either end of the same wire, and accidentally cut power to something else!

I've stripped a couple dozen pounds of wiring and modules out of my car, although I am running a full standalone so it's easier to get rid of stuff.

Just to piss off a certain person. Rasmus I have to say you are so motivated when you want to get something done. I am amazed at how meticulous you are with the weight.

Thanks Mike.

Well the J.B. Weld failed.

After only 18 miles the car started idling weird. Searching. Boost would only go up to .2 kPa.

Hooked up Learning View and my A/F Trims were running +14.99 in some of the boxes which means I have an air leak somewhere and the car was running lean off boost.

[IMG]http://i162.photobucket.com/albums/t278/RasmusHansen/SubaruParts/IMG_4713.jpg[/IMG]
So hooked up my pressure tester. The white PVC endcap with an air fitting on the end. And ran 1 kPa to the system and started spraying places with soapy water.

[IMG]http://i162.photobucket.com/albums/t278/RasmusHansen/SubaruParts/IMG_4712.jpg[/IMG]
Bingo. Leaks all around the TGV bodies and the intake manifold right where I J.B. Welded them together. On the right side; cylinders 1 and 3.

That sucks mate, so you are going to weld it now?
68Cadillac 02-13-2012 08:55 PM

Yep.

GMAW(MIG) with a spool gun. Going to pick up a bottle of argon, some scrap aluminum, and a new stainless steel brush tomorrow. It's all coming off tonight and the old back on. I'll practice for a day or two on the scrap then V groove out the mating line betweenthe TGV bodies and the Intake and weld them together.

I hosted a car lightening clinic here for all the honda fan boys. All we did was remove the stickers from their cars. Took a while, but over all each car lost an average of 75 lbs(note, when removing stickers you also remove WHP).

has anyone got some [B]door glass [/B]laying around that they can [B]weigh[/B] and post the weights, also the windshield and rear window . it would be nice to get a list of some of the weights that haven't been added to page one added right now it takes some digging.

thenewrick 02-24-2012 03:22 AM

I think an aftermarket exhaust and removing the spare/tools is the best way to drop significant weight. I've got AAA so no biggie if I get a flat. This will save about 50 lbs. After that a lightweight crankpulley, lightweight flywheel, carbon fiber drive shaft, lightweight wheels and tires, lightweight 2 piece rotors and you are safe and good to go!

JDwhiteWRX 03-01-2012 07:26 PM

Spec c doors are on their way, I'm going to remove the manual window winders on the rear doors and make brackets to hold the rear windows closed, this should drop a fair bit of extra weight out of them. They have thinner glass too.
gtasti 03-01-2012 11:22 PM

you got all 4 doors spec C whats the difference from usdm ?
JDwhiteWRX 03-02-2012 12:04 AM

[quote=gtasti;36520305]you got all 4 doors spec C whats the difference from usdm ?[/quote]

Yes all four, I can go over them closely when they show up, they are currently in transit. From what I have been told its thinner glass and manual window winders. Also about 10kg in weight savings (will confirm this) but the nice thing is I can leave my original doors in storage and remove some extra metal from the spec c doors.

Please weigh your glass ,the door as a whole ,but also how that weight is divided up in the door pieces .

Unfortunately I just added a little weight too, these new wheels are only 1kg heavier but with tyres its around 4.5kg per wheel. I'm hoping the extra grip is worth it for the extra weight.

17x9 +42 Mach V Awesome.

the enkei rpf 1s may have been lighter in 17-9 did u check
A-man07 03-06-2012 12:09 PM

Kosei K1-TS even lighter but it's close.
68Cadillac 03-06-2012 01:16 PM

Last I looked the Enkei RPF1 and the Kosei K1-TS were the lightest wheels one could buy at a reasonable price. Which one was lightest depended on the size and offset, that's how close they are. I've seen lighter ones but at $850+ per wheel I rolled my eyes and moved on (think, carbon fiber rim with magnesium hub).

And you know what's sad:

Same. Purchased them for STX legality. Wasn't getting the fast times I wanted so I had them power-coated "[COLOR="Red"]Attention-whore Red[/COLOR]". Times didn't get any faster. YMMV.
JDwhiteWRX 03-06-2012 07:20 PM

5x100 is the problem, it really limits you on the wheel choice. My 17x7.5 BBS are 7.1kg each and my new 17x9 are 8.1kg each so its not too bad, most of the extra weight comes from the big tyres.

I can do that with the spec c doors but I am not stripping down my original doors, they are just coming off and going in storage as is.

What's the weight savings over all on those doors JD? I'm dying to know.
JDwhiteWRX 03-09-2012 06:45 PM

[quote=68Cadillac;36590951]What's the weight savings over all on those doors JD? I'm dying to know.[/quote]

Its going to take some time for me to swap them over, a friend of mine said his saved about 10kg but then he gutted them out (track car) and saved 35kg but he only left the intrusion bar on the drivers door.

I am gutting the rears only and fixing the windows in place so they no longer go up and down. The front doors will most likely be left untouched but they should still be lighter than the originals as I can confirm the glass is thinner and the spec c mirrors look to be lighter too. I'm not sure yet if the manual window winders are saving much weight.

I'm weighing everything as I go.
JDwhiteWRX 03-09-2012 11:55 PM

I'm having fun with this, I already pulled 3.5kg out of one of the back doors and thats without touching the intrusion bars which look like they are going to be tricky to remove.

[quote=Supraru;36247626]Now that's not very nice. I'm all for weight savings but as I stated shaving intake manifolds, clips, and messing with small things that might only add up to 10 lbs is stupid and a waste of time. I'm sorry if you're one of these people but still won't change my view.[/quote]

for what it's worth removing the little stuff under the hood does look cleaner.

[quote=bue car;36596151]Curious why do you use metric? More universal for others I assume?[/quote]

If you're asking me it's because metric is better in every way. I'm born and raised in the USA but imperial weights and distances are just vestigial elements of a by-gone era. NASA uses Metric. My Subaru's in Metric. Ford and GM are moving to metric. The world wide scientific community uses metric.

Try adding 11/32, 3/8, 1 3/16, and 3/4 pounds in your head or entering that in to a speadsheet to total up.

Metric is easier. We need to get with the ****ing program before we crash a space probe into Mars. Even your dealer sells you gange in metric.
