Post Your Weights

[Sgt.Gator]

I'd like to start a thread of final weights. As ya'll post them I'll update the 1st post. I think it will be both interesting and useful to see how different builds turn out weight wise. I'll start with Chad's 818R. The format I'd like to keep:

Name / 818R, S, C / Weight with driver / Weight no driver / Left Front/ Right Front/ Left Rear/ Right Rear. Notes

Chad Plavan / 818R / 2266 w/driver/ Unk / 460; 463; 703; 640 . AWIC + Dry Sump. No passenger seat, Fuel Cell in passenger seat area. Full Aero.

Thanks Tamra!

You're welcome. We should have an updated scale result in the spring sometime. Still can't believe how fat our car turned out considering we put effort into using lightweight parts.

Yep. I'm hoping to see the FF goal of an 1,800 lb car posted soon, and how it was done.

[RetroRacing]

We have our wing an wing supports, I'll fire on the wheels and weigh her tonight. Here is hoping....

[FFRSpec72]

So the center drive 818R weighs in at 1850-1870 w/o driver with almost perfectly distributed cross weights, mine is 1905 but a few more things to put on and take off and get better distribution weights

No hearsay evidence here! Please ask them to login and post a few pics and details on their build.

I understand. The intent of the thread is to be a resource for builders to compare notes on weights. Each listing has to link back to at least a builder here that can be contacted with a PM, or to a build thread.
Eventually I'd like to start a parts weight thread like we have on the Corvette Forum. Over the years it has evolved into a hosted spreadsheet where a modder can look up virtually every OEM and aftermarket part made for the C6. It works because there is a huge Corvette community, here we haven't reached that size yet IMHO to make it work. But I know where I want to go eventually. For now, it's just final build weights with links to the information or builder.

I'm going to try adding a build thread column and see if there's enough room.

Awesome, the first under 1800!
Thanks!

[RetroRacing]

I really think you could build a sprint car (30-50 minute) under 1700 with some effort. Alum cell up front, cut off the sway bar mounts (still have to do) no air jacks, CF body, smaller intercooler than ours, smaller oil cooler than ours, no diff/trans cooler or pump, no foam door intrusion stuff, no drop down flat bottom, gut the head lights, lighter wheels (ours are 22.5lbs each), gut the wire harness, ditch the dash for just an IQ3 or Aim and cut out all of the same metal that we did.

Next time.....

[AZPete]

Gator, I weighed some stuff from my donor that might be useful to start a parts weight thread:

Weight of OE parts (06 WRX) in lbs.

Front 4-pot calipers w/ new pads 12
Front lower control arm, aluminum 8
Front brake disc, new 14
Front axle w/ both CV joints & splines 14.5

[Sgt.Gator]

Under 1700 lbs an NA EJ becomes very interesting and possible. No Turbo or Intercooler weight. With me in the car in race gear that would be around 1925. Hmmmm! NASA ST3 would be 192 Hp.

AZPete, thanks, I'll start on my parts weight list.

[RetroRacing]

Under 1700 lbs an NA EJ becomes very interesting and possible. No Turbo or Intercooler weight. With me in the car in race gear that would be around 1925. Hmmmm! NASA ST3 would be 192 Hp I know! Right!!

We could shave 40lbs in wheels IF we wanted to spend 2k in Kodiak's, another 15lbs in air jacks, another 25lbs in fuel cell and associated dry brake plumbing. Add in the weight of our intercooler and turbo (I estimate 40lbs...,it's not a light thing) and you are there easily.

All aluminum N/A peripheral port 13b is over 300hp at 100lbs! No torque, but sounds great at 9000rpm! Keeping it cool, that's another thing entirely!

OK, I have ALMOST finished my alignment, so I still have to adjust corner weight distribution but with side and floor anti intrusion, fire system, full aero (wing, diffuser, splitter, etc), single seat and 7 gals of fuel, I weigh in at UNDER 1800 lbs, so with me @170 I will be under 2000lbs with fuel and driver and gear

[Hindsight]

Wow, that's great!

[FFRSpec72]

Wow, that's great!

I happy given all the gives and takes I made in the build process, so I can say that I'm under 1800, so maybe I'm a 817 ?

[RetroRacing]

VERY COOL!!!!
With the addition of the wrap, extended splitter and such, we are starting to get concerned with our final weight. Mounting final stuff today, should have a revised weight this weekend.

That's pretty amazing. You are 300 less than a couple of other Rs. Great work!
I've updated the table with your info. Thanks.

[Mitch Wright]

Nice work Tony, it is so great to see you getting so close to burning some laps.
Now I have a new goal to be at least 25lb lighter than you.

[Hindsight]

Not running an A2W intercooler is saving a fair amount of weight. I bet it added 40lbs to my build, if you include all components + water.

[FFRSpec72]

Not running an A2W intercooler is saving a fair amount of weight. I bet it added 40lbs to my build, if you include all components + water.

True no AWIC or Dry Sump here but I do have a about 120lbs of added anti-intrusion protection on each side and beneath the seat, I had the FFR build manual and supplement in the car when being weighed so that must have added 10-15 lbs ! I think there are some areas that I can reduce the weight, once I corner balance the car I will look at things to change/remove. Would be nice to be under 1900 with driver and gear.

So Mitch you need to break the 1900lbs with driver and gear !

[Tamra]

That's pretty amazing. You are 300 less than a couple of other Rs. Great work!
I've updated the table with your info. Thanks.

I'm struggling with the math on how this is possible (no offence meant I just want to know how to do the same!). I guess no windshield = -50lbs, no awic = - 50lbs, but then you're saying +120lbs of anti intrusion panels. Your Kirkey's are slightly lighter than our Sparco seats, maybe 20lbs would be optimistic, so that puts us at a wash for weight.

We were at 2058lbs completed, no driver. We did have a relatively full tank of fuel, you're saying 7 gallons, so that's approx 8 gallons of fuel or 65lbs lighter. I'm having a hard time seeing where the rest of the 200lbs comes from. Maybe FFR put some lead in our chassis ;p

Were the scales recently calibrated?

That or our estimate of the AWIC additional weight is way off.

Scales are calibrated as we live real real close to Longacre and they do that for free. , I don't know the S frame weight vs the R frame weight so would need to find that out, I don't have the door hardware the S has, I don't have passenger seat and belts, I have a aluminum fuel cell and not the steel FFR one, I have an EJ207v7 and 5sp transmission, all the extra brackets and crap removed from engine, no fans, Wing mount and trans protection was about 25lbs, not sure what GT250 wing weighs. I'm using a Ultrasheild rally sport seat that weighs in @ 14.5 lbs, using the FFR rims and Hoosier tires, willwood 4 piston brakes, iWire harmess (which was like 20 lbs), aluminum radiator.

Okay, I can see how that would add up more. Our seats are 20lbs each and we have two, so that's ~25lbs savings there. Your engine and turbo probably weighs a bit less than our 2.5 with Borg Warner turbo (it weighs 25lbs alone). I bet your Wilwood brakes saved quite a bit of weight, but I'm not sure how to quantify it. We actually got our own harness down to within a pound or so of the IWire. Must just be a variety of things that all add up I guess.

We will be weighing ours again soon now that we've done a bit more lightening over the winter.

I bet our engine weights are 50-70lbs different and add in the turbo, that may be close to 75-100lbs difference right there. I will also get more weights as I play around and adjust/replace things, hopefully my weight will not increase

[Mitch Wright]

Not sure I can get there Tony being 190lb's but believe me I am doing all I can to save a few ounces here and there, I have even lost 20lb.

I believe the R chassis is a bit heavier but we don't use the door hardware, the doors are bolted to the side sail and rocker. Like Tony I am running a 15 gallon cell (mine is in the passengers seat area) a JDM header is 15lb lighter than the cast iron OE exhaust, small 10"X3" muffler, all tube rear links, AP brakes and hats (almost -40lb from OE brakes) 3.5lb battery, Iwire harness, rear firewall and fuel cell firewall is 15lb lighter than FFR's, Steering shaft 10+lb lighter than OE, Wilwood pedal box is a lot lighter than OE, 9lb flywheel, mounts, tabs and brackets are aluminum or thin wall 4130, no e-brake mechanism or cables and I am running one 10" fan are a few things I have done.
I am getting the car back together and will have back on the scales in the next week, Had on the scales a few weeks ago with the rear fascia and hood off the car, I believe I will be little lighter than Tony when all back together. Now I am excited to get it back on the scales.

[RetroRacing]

I found your 20 lbs.......

[Sgt.Gator]

Hmmm, now doing all of the above that Mitch, Tony, and Retro have done, then swap in a NA 2.5i. No Turbo, No Intercooler. 17" wheels with 245 tires (Enkei PF01 + BFG GFR1 = 40 lbs vs Rota 18 x 9.5 + Toyo RA1 275/35/18 = 49 lbs) and we're getting down to a really light and fast little car that will be cheap to operate. Maybe under 1,700 lbs with no driver.
This is getting better all the time!

[Mitch Wright]

Well share where that free loading 20lb is??? :-)

[Wayne Presley]

I just finished one, Wilwood brakes, Enkei wheels, VCP AWIC, Kirkey seats.

If I were to do it again (Which I have no desire to :) ) I would go 2.5L NA for sure. It would be so much simpler, & lighter.

[FFRSpec72]

So I did my corner weights yesterday and seems the car is at a 45% front and 55% rear weight distribution with me in the car.

[Mitch Wright]

T.hat is close to where lie am less a few body panels.

[Mitch Wright]

Finally set the car on the scales, got the alignment done still a little work to do with me in the car but not in bad shape. Was really shooting for sub 1800lb. Got close but not quite, winter project. Wet with 5 gallons of fuel, I am pleased. 1816lb, 2005lb with me sitting in the car with gear.

True Wayne, that does make me smile. Tony still is at least 25lb lighter, I will go on a hunting mission this winter but i am pleased.

Thanks Hindsight.

I will re-weigh soon as I have added a few items but also I have removed some items, I don't expect much change. Really nice job coming in that low. I see you have similar x-balance, I'm not real happy with weight distribution with the rear being so heavy, I'm sure I will have to use brake bias to reduce front.

[Sgt.Gator]

It's great to see two cars right at or under 1,800 lbs. Good work to both of you!

[Mitch Wright]

I have tweaked the front caster and camber on the right front and reset the toe. Once done I am going back on the scales with 1/2 tank and full tank of fuel to see where I am and then work on getting the rear corners closer.
As a go-kart playing around on the skid pad I was able to play around with brake bias, I did 2 1/2 turn to the rear (Had the bar centered) to get all lock close on all 4 wheels. That was on rock hard tires that were the same size, I am sure it will take some tuning with better rubber and bigger rubber on the rear.

[RetroRacing]

Great job!!! I must admit that I'm a little disappointed with our weight, but with air jacks and a 30 gallon cell, I shouldn't be. Oh well, more power.........

[Hindsight]

2095lbs. 818S, Enkei RPF1 wheels, AWIC, remote oil cooler, momo racing seats, full interior with no carpet, ABS, 100% full tank of gas, bigger roll bar, custom 3" exhaust, 5 speed. Those are all the things/mods that may contribute to weight. 65 or 70 of those pounds are fuel. So pretty close to 2,000.
Without me in it:
LF 443 RF 429

[Wayne Presley]

Did they correct your cross weights after weighing?

[Hindsight]

No, I didnt want them to yet. I am switching springs and raising the height from the 4" I am at now to the full 4.5" so I am not scraping as bad. Once all that is done, I will go back to have the cross weight dialed in.

I'll have to weigh it again when the car comes back to Maryland. The only data I have is on the old turbo with low fuel, no wing, no driver, no safety gear and it was

Huge difference! It was on Rota Grids with bald 235 street tires, no splitter, no diffuser, no door mirrors. The little things add up.

Geez, why is my car so chubby?!? We have the same wheels (though I do have 18s in the back), and I have the same full tank of gas and street windshield. You say "STI AWIC" - do you mean STI A2AIC? But even if you have an air to air, the A2W I have is only 50lbs, which doesn't explain the difference in weight of over 200lbs.

[phil1734]

Me too. I have about 500 shake-down miles on it now but it's going into storage for winter within the next few days. Hopefully Santa brings me a new clutch and some sticky tires and it'll be off to Gingerman in the spring.

It's the same track that FFR did the initial press days at with the 818R. I've never seen a time posted but I'm sure someone somewhere has one. If not I have plenty of other benchmarks to go off of from there.

Weighed our 818S today.

http://thefactoryfiveforum.com/attachment.php?attachmentid=62151&d=1482393068 62152

Things that affected the weight compared to a stock 818S
Front 14 gallon tank was full.
Front internal bumper (approx. 50 Lbs)
Rear internal bumper (approx. 50 Lbs)
Kirkey race seats (no seat brackets)
AWIC System
Dry Sump System
Stock front heavy cast iron Calipers on all four corners.
Stock front heavy rotor on all four corners.
50% larger roll bar.
10lb agm battery near transmission
No Carbon installed yet.

By the numbers
FL 428 20.6%
FR 443 21.3%
RL 612 29.4%
RR 598 28.7%
Total 2081

Front 871 41.9%

Not bad for a car that we using a caliper to measure the length of the springs to set the balance.

Thanks Bob. I updated the table to include both your Go Kart mode and nearly final weights are listed so builders can judge where they are at during the build process.
Merry Christmas Everyone!

Looks like Tony may Win the 2016 Lightest 818 award!

Now if Phil's car were an R instead of an S Tony would have some dieting to do.....

Any more contenders coming in to unseat Tony for 2016?

[phil1734]

What's the prize?

I have a cordless Dewalt and a box of drill bits if you make it worth my time. ;)

[Hindsight]

So my car weighs abt the same as Bob's, but I have no dry sump or add on bumpers. Starting to wonder if the scales I was weighed on were wrong lol. I don't get why my car is so pudgy!

[Hindsight]

AAIC** Oops! So, I don't have a splitter or wing yet ($), I don't have front fender liners, and in this measurement I didn't have my windshield wiper. Did that help in the difference?

I don't think any of that really weighs much. I have none of that installed on mine yet either.

[Sgt.Gator]

Bump. We must have some more 818s +r ready for spring track time!

[Innkeepr]

No completed "C"s yet ? guessing 2200 based in completed "S" models shown.

Yes, I was at 1851, with dry sump, wrap, dash, etc. so not sure if I am still in the lead or if I have fallen off

[FFRSpec72]

So I was working on my challenge car over the weekend, making sure it is ready for the season and was doing the alignment and cross balance and looks like the challenge car is about 500 lbs more than the 818R, so I'm about 100lb over the minimum of 2400 for the challenge car

And an S too!
I'll edit your listing, post up your new corner weights if you get a chance too.

If you have a standard battery you can lose 20lbs with a LI-Ion battery. I've learned a great deal about them the last few months.... if you decide to go that route be very careful. I'm a dealer for EarthX batteries now. They are primarily in the aircraft market but are making a push for the automotive racing market.

[phil1734]

Didn't realize the batteries had gotten that light. I'll definitely have to give it more consideration now seeing as my donor battery is at least ten years old anyway. Do you still need a special trickle charger for the li-ion?

Seats should be in within a few weeks so I'll do a full update then.

[Wayne Presley]

, yes lithium batteries do require a special charger

In danger of threadjacking my own thread, but:
It depends!
From EarthX on their batteries:
In the event you have to charge the battery, use a Lithium (LiFePO4) battery charger or a lead-acid battery charger that does not charge above 14.6V, will automatically turns off when the battery is fully charged (based on volts) and does not have a de-sulfate mode. Do not use any charger with voltage that pulses above 15V! This will damage the battery. If in doubt, consult the manual that comes with your charger.

For chargers with a maintenance mode, the maintenance mode voltage should be 13.3V – 13.9V. For example, the Battery Tender JR has a maintenance mode voltage of 13.3V which is compatible, whereas the original Battery Tender or Battery Tender Plus has a maintenance mode voltage of 13.2V which is too low for a lithium battery. Please read the manual that comes with your charger.

There's more at this link including a list of chargers that will , and those that will not, work:
http://earthxbatteries.com/our-batteries/battery-charging

The Tenergy LiFePO4 Battery Pack Charger is on the list and is also recommended by InduraPower who I met at the PRI show.

2.5NA, Gen2 nose, Post #95 for full specs


Full specs: 2003 TS Wagon donor. 13lb flywheel. Everything from kit installed except carpet and parking brake boot. Mostly vinyl wrapped interior. Wiper kit. iWire harness. Rocker extensions and big fiberglass hooptie wing/third brake light mount. FFR wheels. Kirkey intermediate road race seats. Momo Quark steering wheel. Not a single fan on it, including the radiator. Just some crafty ducting. Still have a lead-acid boat anchor up front to start the thing. No radio or anything that could be accidentally construed as a "luxury."

Because of the variations in full tanks that are used, I topped off and subtracted 78lbs (12 gallons) worth of fuel according to my weight distribution. Not an industry standard, but it allows better comparison to other builds and everybody is reporting with a random fuel load anyway. So technically curb weight is 1,871, but that doesn't sound as nice.

P.S. Anyone over 2400lbs (coupes) on a stock WRX engine have a worse hp/lb ratio than my car. :D

[Sgt.Gator]

Thanks Phil. I edited the table with your new info. Great to see an NA Build coming in nice and light!
Although Tony is still the leader because his weight includes 7 gals of fuel.

[phil1734]

For sure.

I might get him if I switch to Li-ion and finish trimming the body. I swear FFR mixes depleted uranium dust into their fiberglass resin.

If you go Li-ion: I'm a EarthX dealer and can get you one at a good price. PM me. They have features you won't find in the cheap ones, their major market is aircraft where failure is not an option!

[Rob T]

Gator: Came out nicely with the Halo Mod. Is it what you expected?

[Sgt.Gator]

Initially I figured this would be about the weight. Then when the halo was done and we weighed it in Go Kart mode I thought the final weight would be 90 lbs lighter. I didn't factor in enough weight for coolant, fuel, oil, the duct work, and the DS pump - tank.

Interestingly it only added 15 lbs mre than when Brando had it with a dry sump. I attribute that to my swapping the PC680 battery for a EarthX Lithium Ion, and removing the passenger seat.
If anyone wants more info on EarthX batteries i'll be happy to help ou, I'm an authorized dealer. The one in my 8818R weighs 5lbs and has way more crank power than a PC 680 style battery. I'll post a vendor page in the Electrical section.
