So, who's weighed their car? Where?How heavy FR/RR? - 01/10/15 06:27 AM

With all the threads about T-bars/springs/shocks I've been curious about this. It seems to me to be a shot in the dark unless you have good data on what the car weighs. The published shipping weights are at best an approximation. In my case Ma Mopar never built one like mine. It's getting close to d-day for my beast and once that happens I'd like to get the car weighed, even just @ the local dump, though preferably somewhere with a 4 corner scale.
So, what are YOUR #s?

Re: So, who's weighed their car? Where?How heavy FR/RR? - 01/10/15 06:48 AM

Mine is approx. 3,480 lbs. wet/full fuel cell.
Stripped down with full cage and cast iron aluminum head 340.
No idea front to rear bias. I will weigh it again once I get the engine swapped

Is that a lot for an E body? I'm assuming adding the cage added more weight than stripping the interior did.

Funny thing is that it weighs less than many modern RWD cars

Mine weighed 3240 with no backseat,steel hood,steel wheels and a 400/451 auto. I would be pleased if it still weighed that but I doubt it is any lighter after cage and Gen III swap.

Here are my weights. '70 Challenger, aluminum headed B stroker, 5 speed, AC, frame connectors & torque boxes, battery in trunk, full original style interior. Weight includes me, small tool box, full spare and jack:

Front 2,120 54%
Rear 1,849 46%
Total 3,960

I weighed at a local sand and gravel vendor accurate +/- 20 lbs. Lightening plans include 1) loose the "big Chrysler" alternator 2) Aluminum MC. Probably worth 25 lbs on the nose.

Here's one for all those out there that like to say the 6-cyl was a better balanced package than even the 340 cars...

70 Challenger. 225, 3-speed stick, 7 1/4", drums, 14's, NO options at all. 100% bone stock survivor weighed on some really cool 4-wheel stock car scales:

3000lbs (+/- 10-15lbs)
59% front
41% rear

Left/right was pretty close.

Thought for SURE this thing would be a nicely balanced car... for an E-body anyways... but nope. I've heard most 340 (HP) E-bodies were better than 60/40%... I guess this thing just has NOTHING out back... or maybe that 7 1/4" weighs about 50lbs. That slant six sure aint no lightweight... There is nothing heavy up front on this car either... tiny rad, no sway bar, tiny drums, 2-speed wipers, power-nuthin', just nuthin'.

Gonna be a helluva fight getting this thing to a nice 50/50 with a V8 and all that goes with it...

That's close to the setup of my car before the last teardown, but there have been so many changes that it's irrelevant to the way it is now. Do you know somewhere local that I can get my car scaled?

It isn't a total shot in the dark, and obviously the more you know about your particular set up, the better you can dial it in. However, as demonstrated by a lot of the feedback in this thread, an approximate range of 55-60% front bias is a reasonable starting point for most combinations to at least get you in the parking lot of the ball park...

Four corner scales are the best way to know exactly where you are at, but even a front/rear check at the local rock yard/dump/drywall supplier/truck scale/track scale is a fair starting point.

Re: So, who's weighed their car? Where?How heavy FR/RR? - 01/11/15 03:52 PM

I'll post what I've got. It's no secret as its been posted on my website (now considered old fashined plain html) for years. For tech geeks its on my Handling Theory & Data page

Weighed at Englishtown (w/ 150 lbs. of tools) subtracting the tools.
1967 Barracuda Notchback, 340
3240 lbs.
Weighed in 2003 at 3201 lbs. 58 % on the front.
(For setting alignment I load the front seat with weights. Above weight was no driver.)
In terms of weight, the car is basically stock, plain jane with manual steering. Exceptions being aluminum intake & water pump and the wheels.
editWeight in 2003 was with 14" cast slot rims and street tires, 1/2 tank of fuel, spare.

In 2005, with new springs & t-bars, circle racing rims, Hoosier "Street TD" tires 245/50-15, full tank, no spare, was about 30 lbs less. After adjusting t-bars, the weight balance ended up 57.5% front with driver seated weighted, and 3310 lbs total.
Weighting the driver seat did not effect the fr/rr balance much, but did effect the side to side. So this was important to do before adjusting the t-bars and reattaching the sway bar links.

Stock Barracuda Wt & Wt Distribution from Published Data.
1966 Barracuda S 3280 lbs. 56 % ft. (w/ driver) Road & Track
1966 Barracuda S 2820 curb, 3100 test 57 % ft. (w/ driver) Car & Driver
1967 NB 6 a/c 3280 curb, 3580 test, 58.9 % Car Life
1967 FB 273 p/b 3310 curb, 3720 test, 54.9 % Car Life
1969 FB 340 p/b p/s 3470 curb, 3650 test, 55.1 % (w/ driver) Car Life (car tested w/ K-H alum. rims)
1969 FB 440 3405 curb, 3740 test, 57.2 % (w/ driver) Car Life

1970 340 p/s p/b 3630 curb, 4020 test, 56 % (w/ driver) Car Life
1970 AAR 3585 curb 56.1 % Car Life
1972 340 p/s p/b 3520 curb 56.8 % Car & Driver

Magazine articles cited all reprinted in Brooklands Books Plymouth Barracuda 1964-1974

Basically, of the Barracudas and Chllengers, a fastback second gen or first gen Barracuda is probably the best starting point in terms of front to rear balance. The first generation is the lightest starting point, and amongst the second generation notchbacks start lighter than the fastbacks.

For racing and autocross, its generally hard to get down to the minimum class weights especially if you're also working toward 50/50 balance. This is based on numbers I've seen from A and E body race cars.

318/904, al wheels, al radiator, really heavy 3" exhaust dumped at the axle, full interior, 11-3/4" front brakes/rear drums. ~1/4tank of fuel

We'll see how much weight I add with the Hemi/T56 Magnum swap.

Re: So, who's weighed their car? Where?How heavy FR/RR? - 01/12/15 02:22 AM

Using the highway weigh station scales:

'71 Challenger conv, all-iron small block auto, 8 3/4, without driver and 1/2 tank fuel:

3500

53% front

47% rear

That's the heaviest one I have, all my other E-bodies are 3450 and under on the same scale.

Point of interest, I rented a fully loaded 2014 Wrangler Unlimited and on the same scales that thing was 51% frt and 49% rear.

The steering response and handling in that thing was exceptional for what it is.

Here are the corner weights from the '09 2dr Wrangler I had. With an increased track and high roll centers, it handled pretty darn well. Their weight distribution is what helps make them so potent off road and in adverse conditions...they'll walk around any similar equipped pickup in a situation.

Very impressed overall with it. I bet maybe you've heard already, but that Pentastar six was also very impressive for fuel mileage. The current auto transmission not so much; the 8 speed will be the way to go when it becomes available.

Right you are going with your original post of some 3,400 pounds for your current car,,,,makes it some 1,000 pounds lighter than the new Hellcat....which is spec'd at 4,400 pounds.


Figuring hp to weight and all that, what's that 1,000 pounds cost,,,likely some 150 horsepower???? 700 plus hp sounds not so impressive now!

I honestly think that it doesn't need it. Current Vipers make 640hp which is only about 10% less than the 707hp of a Hellcat engine. Most people with average driving skill like myself, can hardly utilize 250-300 hp at a road course. Anything over 500hp, I would want aerodynamic downforce and 50/50 front/rear. To me, the Viper ACR is an impressive balanced package while the Hellcat isn't.

YES!!! I've been saying this for years. I've beat a LOT ov fast cars in my 225HP GT Mustang. With a 320HP Cobra engine and basic bolt-ons i'd be an utter menace.

BUT... we are talking superubercars here, and as with the silly Hellcats and 350Shelby's, reason is out the window. The ACR Viper sounds like a sound package... but it still SOUNDS like (to quote someone else here) a UPS truck. Hell... whether a Hellcat plant or 'just' the SRT8 6.4L... please just make it a V8.

How about that ACR with an ALL aluminum 7L 426 (gen 3) Hemi and 640HP... Yummy.

I have had the opportunity to watch the Vipers on the track, all Generation at once and all with great drivers. The refinement of the 08-10's is HUGE, and I can only imagine the better tweaks and balance on the Gen 5's.

Yep. Need to get that heavy 24F Interstate off the front. Thinking a Odyssey battery under the passenger seat.

And need to get Willwood or Dr Diff brake kit with aluminum hubs. Thinking those two things could get 100 lbs off the front.

BTW those wireless scales were pretty cool!

That's a lot of interesting data Steve
Interesting that with the common pre->post configuration, i.e. w/o driver w spare, you lost nearly the same amount of weight fr/rr -84/-71. Looking @ it a little differently total weight loss 155 lbs, 54% fr 46% rr.
