Any drop in MPG with lighter flywheels on the 1.5T?

Adding a lightweight flywheel in and of itself wonā€™t effect gas mileage. HOWEVERā€¦ if youā€™re interested in installing a lightweight flywheelā€¦. Then I believe itā€™s safe to assume you plan on using it for its intended benefitā€¦ faster revving.
So, having said thatā€¦ that is no adverse effect on fuel mileage. Itā€™s thepossible associated hauling ass and revving that will waste more gasā€¦ lol. Enjoy

Interesting feed: I own a 19 Si im fbo. I have a w1 and a CM fly wheel. Some say i don't need to upgrade the oem clutch others say I should if i want higher revs. I returned the fx 350 back to CM because i didn't see how much wheel horse power if any the set up would give me. I noted exedy does though. Whats Brand is recommended for street race set up. That will complement my fly wheel and W1 turbo. This is my daily but i like to pass slow drivers under 60mph an occasional street race?

You're FBO and W1 turbo and you're not slipping? How's your driving style?

Are you tuned? I'd think you are with the W1.

Not yet. My turbo hasn't been installed yet. I have an opportunity to purchase a fx400 at a great price, just want to cross my T's & dot my I's before committing.

Oh ok. I'm just still trying to wrap my head around pple who are FBO and driving it aggressively with zero issues vs others who are stock slip it almost right away. It's very weird. I remember watching Cameron Hill and all the WOT pulls and racing he did and he had zero slip. I got the rv6 retrofit clutch waiting to be installed. I just don't trust the stock clutch with it's bi polarness. That's why I've stopped all power mods and will not go above Map 2 on my Phearable 1.5 tune until the clutch is swapped out.

Exedy themselves have stated that Honda didn't spec a strong enough clutch, so it seems the OEM one is right on the edge. Makes sense then that some people have issues and some don't. Probably depends somewhat on how it was originally broken in and driving style.

I hear this. Iā€™m on Map 3 with a modded Ktuner OTS dual tune, and I rarely go full throttle, or past 50% throttle at RPMs below 3K. Need the clutch to last Until I can swap it out. I also have an RV6 + Exedy Stage 1 ready to throw in. I long for the days when I can give it any throttle I want, at any RPM, and not have to worry about slippage.

ā˜šŸ¼ Iā€™ll just add that too light of a flywheel will throw a CEL. RV6 did their homework, and only lightened it enough for better responsiveness while ensuring no code.
