RACE CARS how much do you guys WEIGH?
Done some searching and it seems like 2000# and under is pretty hard but a few guys are listing 1800s and one said somethin like 1780 just wonderin if that is possible without hacking the body!
|
I highly doubt it. My 83GSL with a 13bt in it was 2600 with it guted behind the seats and me in the car. I'm230 so the car was 2360. I'd like to hear from some1 else who has actually weighed their car. And I have a Momo Corse seat so that's lighter too...
|
I would really like to know how much the racecars weigh as well. I am really curious as to how low weight they can get down to.
|
If it was an SA I can see the weight at 2000 maybe.
|
cheak out the race car tech section, they may beable to help you more

There is some Norweigen chap who has their car down to like 1600lbs (or something), with an insain roll cage in it. I found it on google once. It is a FB to die for. The roll cage has to be really heavy, it is very elaborate. The car has fiberglass hood and front fenders formed as 1 if I rember corectly. It has lexan windows everwhere. I have no doubt that you could get any Rx-7 down to 2000lbs with out replacing any boddy panels.
You just have to really gut the sucker. |

I weighed mine at about 2390lb with a full interior, you cna find what i have done to the car here:
https://www.rx7club.com/showthread.p...ghlight=weight as you will be able to tell everything interior was left on, I have a 12a NA as oppose to a 13 B with all the turbo stuff which can quickly add up a hundred or so. So 2000# i can see that no problem |
ive got a gutted se, i'll drive it up to the recyclers in the next couple of days and get the weight.
i have been curious myself. |
Mine weighed in at 2450 with a big stereo and full carpet and stock interior. and about 1/2 tank of gas. Now my engine is out and my turbo is coming this week so then ill weigh it after i get the turboed engine back in

My 1979 GTU road racer currently weighs 2080 pounds; I have had it down lighter in the past. It has a very heavy, very rigid cage in it, and it has a G-Force GF-5R transmission that weighs 50 pounds more than the Mazda transmission. Naturally aspirated engines are much lighter than turbo engines; I have a peripheral port engine.
The first few hundred pounds are cheap and easy to remove from a first gen, then it starts getting very labor intensive and very expensive. At the stage I am at now, it is now costing about $50 a pound to replace a part with a lighter one. I have 'glass front fenders, nose, hood, rear fenders, and lexan windows. Ever time I do a lightening/modifying project, I have carefully saved each scrap of material removed and weighed it, and compared it with the replacement race part. |

Is that from Road Atlanta? |
Nice car!

2750 on a 1985 GSL-SE
with Full Interior, Spare, Jack, 6 point steel cage, 1/2 tank of gas, Ford 8.8 rear End - without me in it. |
2wankel how much would you say the cage has added? and i would assume that you have no interior or dash etc.
|
Funny all these responses, and only 3 people that have actually weighed their cars...

My ITA car weights 2325 lbs with a 200 pound driver, minimum allowed weight is 2280 wet. My EP car used (may it RIP) to weight 2150 with same driver, minimum allowed weight is 2050 with stock transmission. The car I'm currently building will have all the lightening tricks available and I hope it comes in at 2100 with me at 175. Going drycell battery and will try no alternator as well.
Take a look at this link for a discussion of 1st gen weight, and some hints. http://prodracing.com/prodcar/viewtopic.php?t=7076 |

When in doubt, listen to the (particially obscured) sign that reads 'ad Atalanta'. |

The 84-85 GSL-SE is the heaviest of the RX-7's, while any GS is probably the lightest without the sunroof. The GS curbed at about 2360lb while the GSL-SE was close to 2500, in stock form. Any modification will affect the weight in some way. Directfreak's car is a GSL-SE with full interior, full roll cage, heavy ford 8.8 rear end, and all the parts for the turbo, which in themselves are heavy. 2700lb for a car like that is pretty good IMO. 2200lb seems to be the easy number to get to. Just strip anything heavy you can off the car. Its getting past that that is the hard part.

My 79 SA weighs 2500 with me (175) in it. I took out the spare tire and tools, and thats about it. It has a 5speed and 13B
|
Cpa7man looks like your the lightest so far the only car under 2000 lbs what are the lightening tricks you are doing to get 1900 lbs ?
