Looks very stout. Ya probably can cut out alot of that front plate, with some type of pattery or whatever that will lighten it up some and still not lose any of the rigidity of the brackets.

Granted I am on an alum block but have a full 10 pt in my car and I'm 280, and with the nitrous system (not the weight you have there but it's still 40 lbs of stuff) I'm at 3330, and still have the stock k member, 60 lbs of exhaust that I can drop off the day I get home from pinks allout @ etown, and there's still probably 25 lbs of wire and nonsense that I know I can lose. Door bars are still in, stock hood still on my car.

I think, that even with me @ 280 I think I can get the car to about 3100 to 3050 with me in it, so if I can get myself to 230 then it should be 3050 to 3000 with me in it.

I dunno if all that supercharger stuff and your block are another 600 lbs, somehow I don't think that stuff can weigh that much can it?

I think my car is 3150-3200 right now, aluminum block, I need to weigh it.

Car looks great it's gonna fly.

I run a CSR trans shield.

Same here on the CSR shield.

We just recently swapped my converter and it is a bitch to deal with, but I'd much rather have that, then be an invilid after a tranny drum decides to exit stage left.

Man, how do you guys get so light? The procharger set-up is about 100lbs I would guess. When I was at 3700 I already had the D1 set-up with an intercooler, so I'm not gaining much more from this new f2 set-up other than the brackets. That's +50lbs, then the lsx is +100lbs. So I'm up to 3850. Things I've removed since then include, k-member, a-arms, door bars, carpet, front seats replaced with one kirkey, power steering, water pump and switched from a 4l60E to a th400. Maybe I'll be a little lighter than I thought, I forgot about some of that stuff. I don't see me getting under 3500 race weight though, there is nothing else to remove except extra metal by hacking. I can cut some of the bracket out but I'm scared to go through all this and then weaken it too much. I need an engineer to draw out a pattern for me where I can cut out all the extra metal without sacraficing strength. I bet I can get it down to about half the weight, I just don't want to screw it up and have to do it all over again.

The lsx block is 140 lbs mor then an alum block is, the regular 6 litre block is 96 lbs heavier.

If you bore the lsx to a 4.185 bore, you take 5 lbs of material out per cylinder

THe factory carpet with the backing is 35 lbs, the ozite I put in is 5 lbs.

That rubber mat I told you to rip off is 40 lbs of nothing. Stuff like that adds up quick!

Oh, my facotry leather power seats were 50 lbs each, the kirkey with the cover is 11. I don't have any brackets to add either because I put the seat right on the floor. Front bumper support was 32

I gotta get that plastic mat out, 40lbs is a lot. Stupid dash is in the way though

Doesn't that mat keep the heat out though? I don't want to be burning up in there. This car will still be street driven

I'd worry about the weight later, you never know how heavy it will really be until you get it on the scales.

I've had mine out for 2 years, makes things a little louder, but with a setup like I have, or what you're doing the noise is just part of it I think. I don't find the car getting any warmer at all after removing it.

rufretic

iTrader: (37)

That's what I'm thinking too, I just want to get this thing up and running and sort the details out later lol.

rufretic

iTrader: (37)

Cool, then it can go.

I suppose where you route your exhaust will influence the heat being transferred from removing the mat.

I've got standard headers on the car, nothing out of the ordinary. I'm sure with his blower setup it will be the same, that being said there shouldn't be any problems.

My 93 will weigh 3200lbs with AC, two leather seats, complete interior (except rear seats), PS, power everything, 10 point cage, iron LT1 block, and turbo setup. There's so much weight you can take out of these cars and still have them look completely stock on the inside.

Here's my thread where I've documented everything I've removed up to this point:
https://ls1tech.com/forums/lt1-lt4-modifications/859437-my-new-1993-z28-project.html

You can also check the weight reduction sticky in the drag race tech section:
https://ls1tech.com/forums/drag-racing-tech/846228-weight-reduction-list-fully-updated.html

When I took that out of my car it 10.03125 lbs. The weight reduction sticky says it is only 13 lbs. You must have had a super thick version? I agree all the small things do add up really quickly. I've taken 297.29095 lbs so far and still have a lot more things left.

That rubber mat behind the dash is only around 10lbs, I just threw mine away the other day.

No way you should be 3850 with all that stuff out.

I have a 25.5 cage, PS, brakes, all interior panels, console, 2 seats, air shifter, fire system, stock hood, not one piece of sheetmetal or brackets cut out, stock length 9 inch, heavy bolt in sway bar, parachute, steel driveshaft, TH400 with an ultra bell, 95% of the stock wiring etc.

The car without me in it as it sits is 3171lbs, from what I have read the LSx is 120lbs heavier, but I bet the 25.5 cage I have is 100+lbs heavier then a 6pt. Drag brakes are good weight savings and fine for limited street use. When its done put in on a scale, only way to know for sure..

I dunno, I had the mat out and it was alot heavier then that.

I took it all out this winter along with drag brakes, a spool and all uneeded wiring, and a motor plate and I added the burkhart bumper support, 60 lbs of exhaust and the front 1/2 of a 10 pt cage and now the car is 3330 with me in it, last year it was 3500.

I know the braked, master cyl and redoing the lines saved weight but not that much. Spool was alot lighter but not that much. Plus I added probably 80 lbs bewteen the exhaust and the rest of the cage, which means I took a total of 250 lbs out of the car, so that weight came from somewhere, and it wasn't off me.

Maybe yours was made to protect the driver in a nuclear war and was lead lined

Not worth arguing about but no way the underdash insulation from my car was anywhere near 40lbs. Its not hard to prove though, all you need is the part and a scale

JL ws-6

iTrader: (50)

Eeh, doesn't matter. I know it's heavy and useless.

I've really wondered where the weight came out, I weigh'ed the car at a different scale/different track, with more gas in teh tank, 3338 so it did lose the 250 lbs, I know it's right from last year too.

Oh well, let's see more pictures of the F2 mounting situation

Everything adds up, people look at my car and they cant believe its as light as it is.

Scales dont lie though, 3300 isnt a bad weight weight to be at. Thats where I was last year before the 25.5. I'd like to get there again but I cant without getting rid of the PS/brakes, cutting some metal out and maybe a powerglide. .1 in the 1/4 isnt going to kill me anyhow, I already did what I wanted to do with it ET-wise with this combination.

Point is dont worry about what it weighs until its done and running
