A friend and I went to our first National Tour Solo II event. Both running in SM2 so we had to get the cars weighed after our runs. Here are the results:

93 R1. Mods: DP, CB, Med IC, CF intake, Eibach springs, GAB R shocks, ACT clutch, J-spec rear seat, stock CD player, factory cruise added, stock wheels with 245/45/16 Kuhmo V700s, water temp and boost guage.

Gas tank was probably only 1-2 gal from full, I filled it up right before my runs.

2796lbs

My friend's 94 Touring/R1. Mods: DP, CB, PFS IC and intake, Eibach springs, GAB R shocks, Mazdatrix clutch, stock wheels with 245/45/16 Kuhmo V700s, Mazdacomp radiator, water temp and boost guage, wideband O2 sensor installed. This car also has a FULL R1 conversion, oil coolers, strut brace, spoilers and seats.

Gas tank was 2 gallons down compared to my 93 R1.

2900lbs

Gas weighs 8lbs/gal so it weighed EXACTLY 120lbs more than my R1.

There was also another FD there, a 94 R2, so I asked him to get his car weighed. His mods were, Tri-Point from bar, boost guage, straight pipe cat-back, GAB R shocks, stock wheels with V700 Kuhmos, no jack or tools, spare installed. This car only had 28K miles on it, original owner.

Gas tank was pretty much exactly the same as mine, 1-2 gal from completely full.

2813lbs

There was another FD in our class, I didn't get his weight. I'll try and PM him and post it up. He had 335/35/17 Hoosiers on the rear, 275s on the front. Man that looked BADASS.

 

When my 94 Touring was corner balanced acouple of years ago, I got:

2724 lbs with approx. 1/2 tank gas, DP, CB, M2 CAI, underdrive pulley, Efini y-pipe, 17lb steel flywheel, Bonez street/comp clutch, Hawker PC680, GC Advance Design coil overs, GAB frt. strut tower bar, stock wheels with Toyo T1S 245/45, boost gauge on RE steering column mount, factory rear spoiler, everything else as it came from the factory. With approx. 10 more gal. fuel at 8lb/gal., that'd be about 2804lbs.

 

I forgot something...

The first two cars are running 51R batteries, about 10lbs lighter than stock.

Trout2, thanks for the datapoint. Another mistake, gas weighs 6lbs/gal, water weighs 8lbs/gal. Sorry guys!

 

My totally stock 93 base model (long time ago ) with 3/8 tank of gas weighed 2780 lbs.

The touring with the R1 "conversion" probably weighed more do to the sunroof. Your R1 and the R2 obviously don't have the sunroof, so they are lighter.

 

Your not saying the sunroof assembly weighs 120lbs are you?

I can see 40 - 50lbs with glass sunroof maybe, but not 120lbs. The little electric motor is not that big at all. There's got to sumthing else adding weight.

 

my 93 touring tipped the scales at 2900 even...full tank...

 

Added weight: rear wiper motor, sunroof, Bose, leather seats, fog lights, ? more sound insulation?

 

i have a full veilside body kit... but taken off alot of the crap... still stock emissions equipment and ac... weighed in two months ago at 2750 (no gas... without me in the car)

 

I weighed my 94 R2 with 3/4 tank of gas with 225/50 RE730 Potenzas all around. Had DP and Cat back, 2 gauges, Profec-B, Tein HA Coilovers. Had everything in the car including spare and what not. Weighed in at 2855lbs w/o me.

Now I have 18's and a small stereo system (1-10'', amp and all) but I have alse got rid of the air pump, gutted my main cat and have a lightened flywheel since then. Don't know the weight but I'am guessing a tad more.

 

Not to mention the cruise control =), as well as the water tank in the rear for the rear wiper.

 

my base weighs right around 2800lbs (according to englishtown dragways scale ) with no ac, full exhaust T78,fmic,ss braided fuel line, extra bracing on diff and trans and ppf, 17" rims that are heavier than stock and much wider

 

Mine weighs 2860 lbs with a full tank of gas. My mods are in my sig.

 

I don't think theres any additional sound insulation in any of the models.... if there is, i'd like to know where... i've owned both an R1 and tourer... everything seemed the same.

 

2712 with 1/4 tank. Weighed at sacramento raceway. That was without the spare tire.

 

Wierd, my car hit the scales at 2615 but I prob only had around 4 gallons of fuel at the most in the car. Its a 1995 PEP and at the time had intake, full exhaust, PFC and thats all, everything else was stock.

My 93 R1 with LT1 and T56 weighs 2780 with a six point cage and 3/4 tank of gas. That was at a truck stop and I think that big scale only measures in increments of ten.

 

We were definetly surprised at the 120lb weight difference. Since I made a mistake with the weight of gas the actual difference was 116lbs.

Figure the 94 Touring was about as heavy as an FD can get.

It has dual oil coolers, R1 strut brace, R1 seats in addition to the stock Touring stuff AND the pass side airbag not on the 93 R1. Read again and you'll see the R1 has cruise, and yes it is an R1, I added it.

So 40-50lb extra for the sunroof is probably reasonable. 5-10lb for the airbag. Add in rear wiper, rear wiper tank and washer, larger radiator (holds more water).

I also thought it was interesting that the 93 R1 and 94 R2 were pretty close. One was modded the other was almost stock.

 

I believe water is 6lbs a gallon and gasoline is 7lbs. At least that is what the literature with Longacre scales says.

My 93 weighed 2754lbs.

 

I was actually surprised how much mine weighed at the last Divisional.

'93 R1: M2 Al CAI, Trust SMIC, Greddy pipes & elbow, Pettit duct, Fluidyne radiator, Bonez DP, Pettit Resonated MP, PowerFC + Commander, old HKS catback, 9.5# RB Flywheel, ACT S/S clutch with HD pressure plate, stockers with 245/45 V700's, Koni Yellows, Tri-Point Adjustable Front Sway Bar, Autometer boost gauge .... almost full tank of gas.

2812 lbs .... that's with the spare and mini-jack still in the back, and a regular ol' Sears Die Hard battery. My car needs to go on a diet.

BTW, the other FD was probably Spank.

 

Water is definetly heavier than gas. Test for yourself.

Yeah the other FD was Spank. He kicked my *** on Sat (I was 4th out of 6), wanted me to be his tire warmer driver on Sun. I declined... I beat him barely on Sun (I was 2nd out of 6) with my 245/45/16s. Not talking trash just happy to beat a couple of guys.

 

1 gallon of gas weighs 6lbs and one gallon of water weighs 8lbs.

and 1 gallon of air weighs 0 lbs.

 

wow thats light...no wonder u have some great times to your name.

Do you have leather and a sunroof?

 

Actually, 1 Gallon of air weighs about 0.01 lb.

1 US Gallon = 3.785 Liters
1 Liter = 1,000 cubic centimeters
1 US Gallon = 3,785 cubic centimeters

1 cubic centimeter of air = 1.239 milligrams @ 20C, 1 atmosphere
3,785 cubic centimeters of air = 4,689.615 milligrams
453,600 milligrams = 1 lb.

Therefore, 1 US Gallon of air = 0.01 lb.
