weighed the FD tonight.
 
i have a 93 base model. leather interior and no sunroof. A/C, power steering, and i had about 1/8th tank of gasoline.

i have intake and full exhaust (with hiflow cat) and all i've removed is the jack and spare tire.

it was 2660lbs

bursty 06-08-07 12:53 AM

Wow! Thats a lot lower then I guessed. Gives me hope to meet my goal of under 2600.

trickshot 06-08-07 01:40 AM

That's lower than I would have expected too. Put your spare and jack on the bathroom scale, then add that to the 2660 and I bet you still come up below the published weight. So what's missing, I have to ask?

The base models are the lightest Fd's.

zack4173 06-08-07 08:46 AM

what have you taken out as far as weight savings im sure you took out the spare and jack but what else?

7dust 06-08-07 08:48 AM

No fat chicks in the FD

NoDrySkin 06-08-07 09:34 AM

The scale is retarded.

FierceAlien 06-08-07 09:41 AM

Keep note he took out the heavy stock exhaust. That will add some #'s to that also.

ptrhahn 06-08-07 09:44 AM

The spare and the jack are worth maybe 20-25 lbs.

The exhaust, sepending on relacement parts, might have saved you 30-40 lbs.

So, you'd be looking at a low 2700 lb. number for a stock car with very little gas in it. Scale is probably within 50-75 lbs of accurate. Weren't the bases 2750?

Fritz Flynn 06-08-07 09:46 AM

Stock weight of an r1 is 2780

His car without the extra cooler and strut bar less 15

Full exhaust less 50

Spare and jack parts less 20

17 gallons of fuel x 5lbs 85

So basically there's nothing wrong with the scale.

These cars are just light which is why we love em :icon_tup:

I always track base or r1 cars and with a roll bar, big brakes, big wheels, big sways, big IC, single turbo, full exhaust, coilovers, rear area stripped bare, no radio, PS or AC they usually weigh between 2600 and 2650. Pull the carpet, passenger seat, the airbag sensors, misc front interior bits and unused electrical stuff etc.... you could easily loose another 50 to 100 :)

All weights are best guesses I'm just trying to point out his scales are fine.

According to the Mazda sales brochure for the U.S. models, the curb weight for a base model with a manual trans. is 2,789 lbs. The R1 with a second oil cooler and the front strut tower brace weighed a little more.

Mazda lists "curb weight." That includes all fluids in the car. How much gas is in it, I don't know, but half a tank is probably a good guess.

The 94 and 95 manual trans cars are listed with a curb weight of 2,826 lbs.

JConn2299 06-08-07 11:36 AM

Autoweek did an extensive test of an R1 and put the weight at 2,815 lbs. Most other magazine sources of the time listed the weight of the '93 R model at 2,800 pounds.

Gasoline weighs 6.25 pounds/gal at 72 F.

Fellas,
Like I said I was just guessing about the specifics and only wanted to point out that his weight was correct and the scales were right :)

However it's always nice to now what a gallon of gas weighs at a certain temp ;)

NoFear99 06-08-07 02:16 PM

I put mine on a truck scale and I got 1280KG , that means about 2816 pounds ..

1/4 of gas in the tank and my car is a Touring 1994.

trickshot 06-08-07 03:04 PM

If the base model weighs 2789 and all he took out was the jack and the spare I still say it doesn't add up. The jack and the spare tire don't weigh 120 pounds.

Spectator 06-08-07 03:50 PM

Ha! I have an FC which weighed in at 2422lbs

...with 212rwhp.

:D

ptrhahn 06-08-07 04:32 PM

He has also replaced all three exhaust system components, which accounts for alot.... and didn't have much gas in it.

And now that you're armed with this valuable information, what are you going to do with it?

turbodrx7 06-08-07 04:37 PM

Mine wieghed 2660 and i have removed power steering and a/c, aswell as have a single turbo, which saves a little weight. Still have the spare tire and jack in the car and had a full tank of gas.

does anyone in here besides fritz know what curb weight actually means? FULL OF LIQUIDS. ie, coolant, oil, 20 gallons of fuel (yea FD's have 20 gallon tanks)

so lets add this up. lets say i had 5 gallons of gasoline.
20gal - 15gal = 15x6.25 = 93

2789 - 93 = 2696
- ~30lbs for the spare and jack = 2666
that's pretty damn close to 2660.

the 30lb spare and jack and 93 lbs of gasoline makes it pretty close.
this also is not taking into account the full exhaust system.

twomucboost4u 06-08-07 04:43 PM

I weighed mine a little while back and it was 2660, Touring model, im hoping to get mine down to around the 2550 mark. I could easily see how a base could get down to 2660.

DBZ33 06-08-07 04:52 PM

I remember back when I had my FD in 99. I had a 94 PEP model with a PFS exhaust it was at 2760lb 1/4 tank of gas.

HKNY 06-08-07 04:57 PM

well figure losing the stock precat drops about 50 lbs alone.I wouldnt nescessarily say the scale was wrong.Find a scrap metal place their scales are usually on the money.
