What kind of weight do you drop from a hood and fenders... I wouldn't think it's a ton.

WRONG sir! ;-)

But seriously it's significant. The hood is pretty dang heavy compared to a fiberglass or aluminum hood. I would guess a solid 10-15lbs difference in the hood alone.

First edit:

for an early car, "longhood"
stock steel hood, early type 35.0 lbs.
fiberglass hood, reinforced 14.0 lbs.

I found a post saying an aluminum short hood is less than 10lbs. I emailed AASE to see what their short hood weighs.

Geronimo, I'm gonna overlook that ugly comment, just once.

Looks like the Getty street hood is around 10lbs, not sure what the stock hood is but that's light.

0-60 with 220hp at 2200 lbs= 4.7s (light SC, 3.2SS motor)
Drop another 200 lbs and it gets to 4.3s...

So, once you have reached 220hp, you can gain 0.2s for each 100lbs lost on the 0-60 acceleration.
Lose 50 lbs yourself and that is 0.1s gained on acceleration.
Wow! That site shows my 550 hp, 2725 lb (with me, 2540 w/o) 930 does 0-60 in 2.773 seconds.

Only true if you could do it without shifting gears!

Maybe compromise and run 28" tires for the 0-60 attempt?

Yeah, I drove a 77 turbo recently and I'm a little worried my SC will feel anemic by comparison. (Hasn't run since way before I got it.)

The problem is this equation only works if your motor is producing the maximum horsepower from the start. Top fuel cars and Teslas may be able to do that. Oh, I forgot about launch control...

I am very aware that for the math to work out, you need to make max power at launch.

But if you wanted to sprint 0-60 without a shift, starting in 2nd would be the easiest way to do so. (taller tires would be second easiest only because it requires a tire-change)

However, muscle cars with manual gearboxes have been launching (as well as doing the best brake-stands) in second gear for a long time. **I'm not in the camp that would stress my 911 driveline like that.**

This 1978 Targa is at 2000lb.

I would say it's on the limit of being streetable. The fiberglass doors are the "worst" part - but also saves about 70lb. But is the most fun I've ever had in an open Porsche. Incredible how 600lb isch changes the characteristics of the car completely. A 260hp ITB/EFI engine also helps a bit

Thats better power to weight than a 991 Carrera by the way

Nux... very cool car and cool color. I haven't been a huge targa fan in the past but you may have just changed my mind!

There's a build thread. Also on my instagram if you like: @nux777

Car is sold now and I miss it already. But I'm going to build another one as I can leave nothing alone and can't sit still haha.

The Targa is somewhat sensitive to hot rod'ing and backdating imo. Not everything works as good as on a coupe. This turned out pretty good I think. And you get the convertible feeling and the sound! And as I said before: a 900kg (2000lb) car is incredibly fun!

Pretty easy: 3.2SS (98mm bore), DC20cams (like 993ss), EFI, ITB, headers, Dynomax 17231 muffler (not the one on the pics).

Lovely engine, pulls great to 7000 and sounds THE bussines.

Aluminum or composite? Do you recall the vendor? Did they seem flimsy? Do you think they could actually do their job or they may just fold up?
