at idle, its kinda same noise as stock just a little louder. maybe some buzzing (i guess thats the word?) in 1st & 2nd from idle to 1500 but not that big of deal IMO. Stock is a dual-mass flywheel that dampens all these noises but stock is also about 30lb.

The cost is about the same cost as a clutch job. It's a perfect mod to do if your clutch is toast, you save on labor.

My car has never been on a dyno, so I have no idea how much power each of the mods make. But I definitely think the flywheel registers more of a difference on the butt dyno than the HFC's.

I didn't do any runs with just the cats alone.

yeah we're definitely lucky to have such a sticky track!

A light weight flywheel had to be one of the best mods I ever did on my G20 and I'm sure it will b on the Z when I do it, but I only got 6400 miles so its probably going to be a while.

I'm gonna be in the 12s before you

I'll let you take my Accord down the track if you let me drive the Z

what are your times on the Accord?

brian0128 · 03-06-2011, 01:02 PM

Congrats on the 12 second timeslip.

b1adesofcha0s · 03-06-2011, 02:50 PM

Congrats on the time!

If I'm correct, flywheel is only for manual transmissions? Is there something that would provide similar performance enhancements for a 7AT? I know 4.08 gears is DB option, but I DD my Z and spend most of my time on the highway, so I don't think I want to go that route.

Jordo! · 03-06-2011, 03:23 PM

Wow -- open dif too! Congrats!

Has anyone found any real advantage to having the LSD?

Higher stall torque converter.

Having a tune so that the shift speed/firmness is tweaked (it's tunable with uprev).

Ohhhh... I thought he said base model, so I assumed, no sport pack

So are all the faster times from folks with a LSD then, OEM or otherwise?

Probably doesn't matter for drag racing. The limited slip comes into play much more when you're powering out of corners and the rear tires are unequally weighted.

I ran my 12.9 on an open diff. Havent went back with the 4.08s and vlsd
