Might want to add a lightweight flywheel into the mix:

Overall weight reduction isn't the reason for going to a light flywheel, but at 20 lbs. savings, it's not a bad side effect...

Is this the lightest flywheel out in the market?

How much weight will the antivirus software save me?

10 to 15 megabytes.

OT, but I wouldn't think you'd want to go any lighter.

I know this is going way back, but when you had the PC680 in the stock location, did you use a custom bracket or anything to hold it in place, or could you use what was there from the stock battery?

You can't use the stock battery mounting ties unfortunately. I used an old mount that I had from my old time attack 350Z. I have been trying to find something similar to sell, but can't find anything like that. I have no idea where the one I used came from or who made it lol. If I start getting a lot of people asking for it then I suppose I can find a CNC shop in town that can make custom ones.

Nice thread - not sure how I missed it before.

Re: hp/lb wasn't the old school formula for every 100lbs you lost you gained the equivalent of 10ish HP? Time to hit the tread mill boys ;) I gained 5hp in two years of going to the gym in every car I drive - sweet! Maybe I should try driving by remote control for another 17.5 HP gain...

For the fluids (washer fluid) wouldn't the easiest measurement be to empty out the tank then measure what you fill it back up with to figure the volume out. Dunno what the specific gravity of washer fluid is but its probably pretty close to water so we'll say 1kg per liter....

Anyone use Lithium Maganese technology for batteries? Might be time to whip up an ultralight battery pack - what kind of capacity would be a decent target to shoot for? Cranking amps isn't going to be an issue here.... Peak voltage is going to be 16.8V and nominal is 14.8V - does anyone know if this needs to be regulated down or is there a regulator already in place after the battery?

Any weight specs on the Stillen exhaust or intake components?

I didn't weight the stillen exhaust but can tell you the muffler was HEAVY... I had another shop build a muffler for my z as well - eventual sold it - but it was about half the weight of the stillen muffler i'd guess... stillen was clearly focused on HPs, not LBs

FYI and thanks to Dean at Stillen (man their support is AWESOME - can't say the same for other companies I've been dealing with lately).....

Cat back exhaust - 90 lbs + 40lbs from stock - ouch
High Flow Cat - 15 lbs -6 lbs from stock
G3 Intake - under 10 lbs

UPDATE: Sorry there was a little miscommunication and I listed the shipping weight here instead of the actual.... thanks Josh for the real world data although if I drive around with the shipping crate I'm still right ;P

Stock Exhaust

Muffler Section - 26.8lbs (highly inefficient)
Y-Pipe - 11.6lbs
Resonated Y-Pipe - 15.6lbs
Total: 54.0lbs

STILLEN Exhaust

Muffler Section - 39.6lbs (proven huge hp gains)
Y-Pipe - 11.3lbs
Resonated Y-Pipe - 14.4lbs
Total: 65.3lbs

Difference: +11.3lbs and 18whp

suppose at least the weight distribution from stillen exhaust goes to the right places... low and back

I can't see how the CBE weighs 40 lbs. more. :ughdance:

I just PMed Josh@Stillen to confirm.

I'm sorry for the confusion, I'll confer with Dean if that's where you got the exhaust numbers. Here's the correct info:

Stock Exhaust

Muffler Section - 26.8lbs (highly inefficient)
Y-Pipe - 11.6lbs
Resonated Y-Pipe - 15.6lbs
Total: 54.0lbs

STILLEN Exhaust

Muffler Section - 39.6lbs (proven huge hp gains)
Y-Pipe - 11.3lbs
Resonated Y-Pipe - 14.4lbs
Total: 65.3lbs

Difference: +11.3lbs and 18whp

Also note that the weight is at the lowest point of the car, over the rear wheels, which will increase traction.

Quick work Josh, thanks!
