I'd be surprised if any of the aftermarket packages lose weight.

 

A lot of it can actually result from the exhaust section design.

If anything, even if weight is gained, I think the community could utilize knowing about it. Weight reduction is a nickel-and-dime accumulation game no matter how you look at it anyway.

 

You will lose in the exhaust and quite a bit if you go titanium, but you will gain that back with bigger intercooler, bigger, turbos, etc. I would be the net would be +/- 5lbs.

then wouldn't you logically lose a significant amount of weight with the Alpha 6, P600, etc. packages?

 

Cost cheaper to make more power than dropping weight

 

sorry, man, not the point...

as much as i'd love to have 900bhp, i hate throwing around 4000lbs of weight incl fluids and passenger... i'd be okay with something like 3600-3700 lbs dry curb weight...

 

My car is about 200-225 lighter than stock,but that includes exhaust and carbon

 

Larger intercoolers, yes - because the materials would grow along with the size (because the core has material).

Larger piping/turbos, etc... - no. Or else we'd see aftermarket exhausts that weigh a LOT more than stock, because of the bigger dimensions (removing the resonators as a point of weight loss). Fact is - sometimes the material weighs less - and the added size is filled with air/nothing. For example a stock steel center pipe of 76mm might weigh more than an aftermarket SS 90mm pipe (depending on thickness).

I figure the same goes for the turbo's, downpipes, etc...

Most of the weight loss we see comes from exhaust components, seats, wheels/tires, and maybe a little from CF panel replacement (relatively - but that starts bringing up the price a little)

 

My car was 3649 on fumes last year @ an SCCA National (so I know the digital scales were accurate). Since then, there's been ~50-55lbs taken out, so it should be sitting @ ~3595 w/ the same fuel load (without the 40# rollbar), and my 18" CCW setup. I'll get the car weighed again next month on same scales to verify. No CF parts on my car, so far. Back seats & all trunk carpeting still in car as well.
Methinks it could be brought down to ~3550 w/ CF hood & trunk, and removing trunk carpeting etc.

It's still heavy compared to my competition, but the car is definitely more lithe than when it was stock weight.

 

As I always tell my wife, going on a diet would save me as much weight as $100k in carbon fiber.

 

build thread - http://www.nagtroc.org/forums/index.php?/topic/57707-r35-gtr-time-attack-build/

want a lighter gtr- strip it and cover with dry carbon fiber This view really shows how close and how different it is to previous nissan chassis. very refined. lots of heavy weight material. alot can be done to the chassis to reduce weigth and make stronger - take for example kazunori Yamauchi's s2000 by opera performance

The budget for doing something like dry carbon body and chassis development would be very very high. Nissan as an oem wouldnt do this. im hoping R36 has a carbon and steel tube chassis much like the lambo aventodor... especially if they decide to go full electric by 2020.

Here is the ZR1 chassis - http://0.tqn.com/d/cars/1/0/2/Q/1/ag_09zr1_alumframe.jpg

huge difference.
