Yes, however I wasn't being at all critical or judgemental. Shed loads is simply the Australian SI unit for lotsAre you asking about the underside of my Spider in the photo on the previous page? If so, the "shed loads of RHS" actually weighs quite a bit less than the standard chassis brace you can get from IAP. I used to have one of those on the car. Both the brace and the materials in the photo were actually weighed.
I didn't take your question that way so, no worries. I just wanted to let you know that even though it may look like a lot of added metal in the photo, it's actually not that much.Yes, however I wasn't being at all critical or judgemental. Shed loads is simply the Australian SI unit for lots
I'm interested in how and where you have braced and cross braced as i'm considering how i might improve the our duetto. It's in pieces at the moment and the RHS you have under the axle, between the rear trailing arms intererests me. The box section below the rear 'seat' needs rebuilding on my car and as such i was considering how it might be repaired better ie. RHS between the innersills, tied to top of trailing arm mounts. getting over the axle is an issue - you appear to have gone under.
Any other photos, drawings or thoughts would be appreciated.
A stock Spider hood weights 26.4 pounds.If the '87 bumpers mount the same as '84, the rear is just 4 bolts each side for the back, with two big screw-head looking guides holding the rear bumpers sides in place. Not too hard to remove if you remember to slide backward out of those guides. I'm interested to see the hood and trunk you're talking about. Please weigh the before and after components so we have solid numbers to go by. I'd love to lose more weight on mine too.
So do you have a list of everything you took off? I’m curious to get my spider weighed soon and have a similar target weight.Update: She's now at 1980 lbs! Happy to have hit my target, but again - Not sure I can go much lighter than this.
@nealric Unfortunately I don't have a list of everything I took off. We rescued the car off a junkyard so it was very rusty, a lot of the rusty metal I've chopped off was not replaced. It's also easy for you to get caught on the weighing of individual take-off parts, then taking the car to a truck scale only to be surprised of how heavy it is.So do you have a list of everything you took off?

Thanks, that’s helpful. I’m certainly not trying to hit an arbitrary number for its own sake, but sub 2,000 does have a nice ring to it. Agree that an extra 100+hp more than makes up for an extra 100lbs.@nealric Unfortunately I don't have a list of everything I took off.

I do know what the car had or lacked between weight-ins, and from experience your list may get you to dip under 2100 lbs. and maybe even to the low 2000 lbs, but no way it will put you in the 1900s (and that is not a bad thing, more on that in a sec.)
You will notice that our mod list is very similar (great minds think alike!) But the key here is that I went with the lightest, biggest carburetors I could find and removed weight from the stock manifold, you are adding to the EFI setup a snail, intercooler, a bunch of piping, oil capacity, a more complex roll bar, etc...
Starting point was a 1986 graduate, so no A/C, audio, or power steering. At 2060 lbs:
At 1980 lbs:
- No roof of any kind
- Wolf Metal dimpled middle sills
- DIY dimpled inner sills
- Cobra Clubman racing seat on DIY sliders
- DIY drilled & dimpled trailing arms
- Duracell Ultra AGM (24 lbs)
- Mille Miglia mags
- Sound deadening removed
- Alfaholics little spring kit in the front (spring pan delete, $$$, will not do it again)
- Deleted rear swaybar
- Front and rear bumper delete (an easy 100 lbs. right there)
- Trunk floor cut off, replaced by a flat piece of very thin steel (don't tell my wife what happened to the file cabinet)
- Fuel tank plate deleted
- 2.5 gal. fuel cell
- Wilwood brake booster delete kit (from a BMW 2002, chasebays makes this part.)
- No wipers
- No wiper fluid reservoir
- Small coolant reservoir, plastic
- YZF R1 carburetors on a custom intake manifold
- Deleted fuel ECU, all associated wiring
- Deleted fuel return circuit
- Swapped fuel pump for a motorcycle interrupter pump (no return circuit or FPR needed.)
- GTAm side pipe
- Naturally-occurring weight-reduction by copious amounts of iron oxide
Now like @Milanoguy said, I don't think this is bad news: I'm running N/A and have MAYBE 140-150whp, it was a rusty POS and much of the metal removed itself from the car so sometimes it does get a bit weebly-wobbly going over bumps (when the alfaholics suspension doesn't want to send the car to the stratosphere. Stuff is STIFF.).
- Wiper motor delete, wiper mechanism delete
- Removed all useless bracketry from the engine bay and cowl area
- Deleted VVT mechanism (new cams IN!)
- Swapped cam cover for an earlier GTV unit
- Spare tire, jack delete
- Removed sun visors
- Cleaned up more of the wiring
- Other stuff I am probably forgetting, will add to the post later
With the power you will be putting down, I would focus on a healthy 2100 lbs. and not get upset if I end up at 2200 lbs, but managed to sneak in a chassis brace and a chunkier roll bar there. These cars are old, safety and stiffness is good!
Forget about the hydraulic hand brake, make sure your fuel cell has more than 2.5 gallons, and reconsider the side pipe if you like your neighborhood or racing events where they actually check for decibels. Although you will be turbo, so maybe it will help quiet down things and add in some interesting noises. Wapooosh!
BTW- I am following your build thread. Keep up the good work!
Price was really steep, and it's really not built for street cars. It's a very harsh ride.Curious why you didn’t like the Alfaholics pan delete. Problem with the kit itself or just overpriced?
I want that. Did you make female molds for it, or did you use the stock hood as a positive mold?
