So how much difference do you think weight makes?

[Hizzle]

I'd like to drop some more weight but not mess with any structural integrity. I have pulled the smog, equipment, went manual steering rack, no A/C, no backseat, and i pulled the insulation out from behind the interior trim panels. It was a bit musty and the sound doesn't bother me. The car also doesn't get driven that much. What have you guys done to shave some weight by either removing other items or replacing some with lighter pieces but not messing with the structural integrity of the vehicle? How much difference do you think shaving weight makes as far as performance? I know a lot of it comes down to weight distribution.

I've always heard that 100lbs is equal to .10 of a second at the track.

 

[68keyblr]

From what I've heard, each 100 lbs = 15 HP.

Aluminum heads will free up a pretty good chunk of weight, as will an aftermarket K-member. Taking weight off of the nose will help overall handling.

You want a HP to weight ratio of 10:1 or lower...the lower, the better in terms of performance.

Good luck

gonna wait on the heads until i build my 347. I don't want to mess with the '86 block and heads/cam due to the compression. It sounds like I need valve reliefs to really run anything. It has E7 heads on it now. The guy put them on not too long before I bought it. The car only has 87,000 miles on it so it should still have some life left in it until I can build the other one.

K-member is coming but waiting until I can afford the coilovers and 5 lug conversion to do at the same time. And since I'll have the axle apart, of course gears.

Theres guys over on the corral who are running 12's with a stock motor and gears.. How? They did crazy ass weight reduction..

 

[88mouse]

pull the bumpers and bumper supports.That at least 50lbs off the car front and back

A good friend of mine went 12.77 @ 105 on a stock motored notch. 3.73s, suspension, MAF, pulleys, exhaust and tires. His wasn't gutted, but did come in right under or around 3000 lbs with him driving it.

Most say 100 lbs is a 10th, and that is a decent round about. It changes with how fast your going and where the 100 lbs comes off.

There's a hatch belonging to one of the MM+FF guys that runs 11.90s and only dynos at 300hp at the wheels. The key is being able to drop enough weight that you can safely add weight back in where you want it to aid in weight transfer. That plus slicks plus driving it with no mercy equals amazing time slips.

A HP to weight ratio of 10:1?

350hp 35lb car?

I think you meant Weight to hp ratio!

Turbo Gixercart?

 

[68keyblr]

yeah, you know what I mean

 

[Mustang5L5]

If you fill your tires with helium, it will lift the car slightly shaving off a hundred pounds or so.

I'm kidding

You're dangerously close to the debate about what weighs less....a compressed tank of air or a compressed tank of helium.

I'm stripping everything but the front seats, even the dash. I should weigh the huge pile of junk that came out of the car!

Some added weight in the name of strength and power isn't a bad thing


Just subtract it from somewhere else.

Troof.. just cant find any place to subtract from! I only weigh about 150lbs... so Im ahead of MOST of the guys at the track already
