the intercooler, piping, water pump, etc...

- CF front fenders: The stock fenders probably weigh 3-4 lbs. each so not much room for any major improvements there. The SEIBON dry carbon might save a lb. or two, but I can almost guarantee that their regular carbon ones are at best, the same weight. They are 10mm wider though, which is awesome.

- CF racing mirrors: Haven't seen any 370Z specific ones yet, but as reference swapping the OEM 350Z mirrors to tiny, non-motorized Craftsquare mirrors saved 1 lb. each side.

- Supercharger system: Expect anywhere from 60-100 lbs. probably in added parts/fluids.

Haha Josh that Gen3 for free sale came too late for me, I would have jumped all over that but went with the Berk group buy, oh well. C'est la vie.

Im sure it will

but any approximation of the weight added? caz it will be abit harder to balance it with the rear..

so if the supercharger weighs 100 lbs, and about 9 lbs is equal to 1 hp, you only need 11.1 hp more to offset the weight increase?

For accelleration, yes. There's no doubt your car will accelerate faster with an SC. Cornering and braking will always be affected negatively by weight though.

Need some clarification from the first page, are stock cats 21lbs each or total?

Total

There is a product that could be considered for weight reduction...It has not been specifically made for the 370z, but Stillen made one for the 350z. It's an aluminum radiator...These radiators are lighter and more efficient than the OEM. It's currently on the Stillen site, so check it out and tell me what u guys think...

I don't think they are lighter than OEM. The OEM 350Z radiator is super thin with plastic end tanks. Incredibly light. Crap, but incredibly light crap. There's also the added amount of coolant which weighs a lb. or two probably.

RCZ · 02-10-2010, 06:01 PM

I was wondering why no one here talks about radiators too much. It was a nice mod in the Subaru community.

travisjb · 02-10-2010, 06:32 PM

Actually, if you're going to remove the a/c (race car or extreme TT car), an aftermarket radiator makes sense... OEM, the radiator and a/c condensor are basically fused together... ie no way to remove the condensor even if you pull the rest of the a/c system... so it is dead weight

Brazilbro · 02-10-2010, 07:02 PM

I was thinking if you remove the a/c and stick in a radiator that is half the length but thicker you could stick a single turbo up front.

370zForever · 02-10-2010, 07:42 PM

Thanks Mike and the rest of you guys,

I thought it would lighten it up a bit cause' that's the main reason I thought of buying it. Better cooling, less weight, better quality and I thought it would be the best, but I since it does not save weight, I'll stick with my oil cooler...

370zForever · 03-20-2010, 06:06 PM

I was wondering if anybody had any more ideas to reduce unsprung weight in the wheel area. I've got my 18" volk ce28n, rays engineering wheel nuts (save about 750g altogether....yeah big savings), and will be getting my AP Racing big brake kit. The wheels and brake kit help the most, but is there anything else that I could do.
