Watching 1320 videos the other day and saw the 7 second, street car, redeye heavily modified. What caught my attention the most is he had full interior, lots of billet stuff, turbos, roll cage, rear seat delete, lighter seats, etc etc. The car was 4900lbs has a carbon roof and doors, now weighing 4200lbs.

My thing is, that's still a heavy car, personally I don't think what hes done is enough to take it from 4900 to 4225 I could be wrong but what are some crazy/smart/practical ways you guys have heard/done/seen to drop weight?

Would like to keep stock motor, stock interior couple carbon fiber parts and see 4000lbs (+/- few). It's probably a far shot but who knows.

Side note this guy said in the years to come hes going to get the car down to 3200lbs, crazy!

One of the quickest ways to shave a lot of weight is to upgrade to CF wheels. They're over $2,000 a piece, but if money is no object and weight savings is the goal, that's an excellent first step. As for getting the car to 3,200lb, I don't think that's even possible unless he makes a promod chassis with a repro fiberglass body shell or something. At that point, it's not a Hellcat anymore.

Keep in mind that 3,200lb is excessively light. My C8 weighs around 3,600lb and is made of plastic, fiberglass, CF, and aluminum.

Yep, what Xylander said. Cutting rotational weight makes a huge difference, especially because rolling weight essentially "weighs more" than static weight. You'll have to search it to get the exact numbers, but if I recall correctly, cutting 1 pound of rotational weight is equivalent to 2x or 2.5X static weight--in other words, cut 10 pounds from your wheels and it's like cutting 20-25 pounds of static weight. Lighter wheels, tires, rotors, driveshaft, axles etc. can make a big difference...albeit, we're talking about a heavy and powerful car so cutting said weight may not make as big of a difference if you did the same on say, a Civic Hatchback (because the percentage of weight cut is much less on such a heavy car like ours) but cutting rotational weight is cutting rotational weight and it's something I've tried to do on all my cars. That's my humble two cents. Good post!

4900????????? I'd question that right away.
2018 Dodge Challenger SRT Hellcat Widebody Specifications

WHEELBASE	116.2 in
WEIGHT	4,490-4,498 lb
0-60 MPH	3.4 sec
TOP SPEED	195 mph

Why 400# more than most specs? Get a scale and pull things out. Seats and different hood would be easy.

It's a very heavy car. IMO, if you are going to gut it and try to get the weight low, a custom build with a HC motor in a lighter car would be better.

I’d imagine with a proper cage for a car that runs 7s and all the beefed up components it could easily add a couple hundred pounds…and I wonder if that weight is with driver too. Not sure, haven't seen the car in question.

In terms of energy of a wheel rolling at a given speed vs a non-rotating mass moving at the same speed, it is 2x if all the mass of the wheel is at the edge (think a bicycle wheel), and 1x if all the mass is at the center, and anywhere in between for a realistic wheel, depending on the mass distribution. The difference between CF, Mg and Al wheels is not going to be very noticeable in terms of acceleration; your suspension will work better with lighter wheels though.

So if you are after acceleration, going for CF or Mg wheels is not a cost-effective solution (at least up to the point where you remove everything heavy that you can remove for free).

There we go, there's a proper reply!

All you fat fux should lose 20, 50, 75 pounds or more first, then worry about the car.

Build a A body mopar

 

[Doublewide]

You can save close to 300lbs by doing the following: (some of these weights are just approximates as I have not personally weighed all these items)
Drag pack: +/-50
Aluminum driveshaft: +/-8
Lithium battery: 25-40
Trunk carpet: 12
Subs: 12
Air pump: 5
Rotors: 25
Back seat: 50
Front passenger seat: 65
Sway bar delete: 20
Floor mats: 5

On a narrow body car, this would get you to about 4100 assuming no sun roof. You could do bumper supports, carbon fiber doors, hood, trunk lid if you really want sub 4k weight

No, it weighed 4200 lbs and that was his requirement for the race.

 

[Unholy707]

Def didn’t weigh 4900, probably said 4500 which is right

James is a personnel friend of mine. His Redeye has been going through weight reduction over the past couple of months.

Those that are involved with his Redeye know a lot about weight reduction. They have been around before the Hellcats and we back then were racing to the 8's.
It was not easy and Weight reduction was needed to get into the 8's. The Hellcat Platform has been awesome for 8's
Going for 7's and 6's is quite different.

Deciding an ET helps with information for weight reduction.

Mediterranean diet has advantages over keto in randomized study

There has long been debate about which low-carbohydrate diets — specifically, Mediterranean vs. ketogenic — offer the greatest health benefits to patients with prediabetes and type 2 diabetes, but a randomized study may offer an answer. Researchers from Stanford University found that both diets...

Yep, but only if you eat processed meats, have to moderate it. Also, it usually only elevates it initially and then after a few months it drops down

It’s expensive. Grass fed, lots of nuts. All healthy things are expensive
