Adding Lightness - gut the fish

[edward993]

Wait a minute! 3000lbs as a goal?? A Stock 993NB coupe purportedly weighs in at 3080. With a gutted interior (don't put in any carpet IMO) and fg seats, you should easily be under 3K.

Well, as light as I can make it without resorting going insane. I'll have AC after all. If the glue and stuck on foam wasn't so gross, I'd definitely go no carpet like a real race car. But for now, I'll cover it up with lightweight RS carpets.

It's just a fun project and I can't want to get it on the track and see how it works.

The glue on foam is nothing that a good adhesive remover can't take off - without hurting the paint. 3M makes a good one, for example.

We DE / TT guys always say "I'll never race", but remember that you may want to go club racing one day. It would be nice if you could go back to stock to run stock class. If you have the room and patience to keep the bits you take off, do so. Otherwise, I am sure we'll be happy to buy your toy for 20 cents on the dollar, so you can buy club racing machine.

I think your decision to leave the a/c in is very good. I only pulled mine because it was dead and I don't do a/c work myself. After getting toasted at Thunderhill in July for a whole couple days, it is NOT much fun to drive home in a hot car through the central valley.

Come see it anytime Matt. Maybe in another year or so they'll let me take passengers.

FYI, no passengers with PCA-GGR, unless you are doing a "family lap" or you graduate to be an instructor. Other clubs like NCRC will let you take passengers though. I recommend to go with GGR for the best instruction.

The lightwt. carpet - per se - is not going to save that much wt.

What you need to do is to remove many pounds of soundproofing gunk. That means the volume reoved will be large. Don't waste time on the thin tendrils of glue you find - unless it's a cosmetic thing - bu tyou can just spread carpet over that.

Bill, Those must be weights for a 993. I went out ot the garage to check my weights and got these:


Rear seat backs at 13 lbs vs 10
Rear seat belts 3 vs 4
Rear bumper pads 14 vs 2
Windshield washer bottle empty 2.5 and 19 full of water vs 12
Cat with shield 15
Muffler 30
Sunvisors 2 (tired of hitting them with my head)
Steering wheel 6
Spare 33.5
Jack 5
Air pump 6.5 versus 40 lbs total for spare, jack and air pump
Also,
Stock air flow meter with filter 8

There is another weight lost list I saw posted but cannot find it now. I'll check areound later.

[Bill Verburg]

yes, those are all 993 weights, as was the subject in this thread

[jtratza]

Thought Don's car rear seat area looked better than mine.

[911mot]

The ratio for weight loss to equivalent HP gain dependds on the weight o the car that is a heavier car like the 993 benefits slightly more than a lighter car like an SC or Carrera

surely as the car gets lighter removing weight has an even bigger difference - because you are removing a bigger percentage of the total weight for every lb you remove. But then again maths wasn't my strong subject either..

[jtratza]

You're absolutely right...and on both accounts. Lighter the car the bigger the gain as far as power to weight. I need another beer before I can complete my calculations. Maybe two beers to check my math.

[Joeaksa]

Good thread, would like to see what kind of weights you come with in the end.

I edited out the posts in this thread containing personal attacks. I hope too much worthwhile content wasn't also chopped, but this thread was getting a lot of complaints.

[jtratza]

Thanks Jack. And to think I thought this was a thread on weight loss and not chip gain. Some day maybe I'll figure out why some people invest so much of their personality in a side line that should be taken as enjoying life. But then I'll be 60 this year and still cannot figure out what growing up is all about.

[Tyson Schmidt]

Hmmmm, I missed the drama.

When did chips enter the discussion?

[Pete000]

Looks like my car did a few months ago. Isnt that yellow glue a bit@& to get off. I could not find any solvant that would cut that stuff. Ended up using gasoline in a well ventalated area. Got most of it out.

I agree lighten the heck out of everything, but Keep the AC !

I have spoken to guys who ripped it out and then driving home from the track in 110 degree heat is no fun sanwiched in a Recaro racing seat sweating for a few hours in traffic.

Me too - I'm very curious to see the final weight results on my Stage I, Stage II Progression.

And keeping the AC - I was strongly considering a fairly raw 74 MFI and Tyson brought clarity and direction back into my thinking based upon my original project goals. I'm very fortunate to have that caliber of advice.

Ultimately, any project is a series of compromises. Even for pure trailed track cars, budgets mean there are always compromises to be made. I'm balancing my goal to build a fun, safe platform to build seat time with budget and what I consider "livability needs". My choices will be different than others -- but I'll be having fun and learning through the process.

To be continued...

what's wrong with a chip that gains 50.454 HP on pump gas
