Rev happy.

[Mikes_Slow5oh]

So I just did a twin disk clutch and a lighter flywheel and holy shit does the fly wheel make a huge difference on how quickly the car revs. It’s running a 2.9L Whipple supercharger with fuel rails, fuel lines, and injectors. It’s going back into be tuned and have an eGauge tuner installed. Right now the car is set at 8k redline and I wanted to know how safe that is. It only has 19k miles and I plan on doing upgraded oil gears this winter but what else is needed to make sure that the engine is safe hitting the 8k mark. I was thinking about dropping the rev limiter to 7500 to be on the safe side but wanted to see what everyone thinks.

I've always wondered why more people don't do lighter flywheels but apparently it can make daily driving more of a chore.

Let us know if you'd do it again after some more time.

I did a single mass flywheel and stage 2 clutch on a G35 years ago...sounded like a cement truck in neutral...had to engage the clutch to keep from being embarrassed. Are the S550s duel-mass flywheels?

2018+ are

2018+ are

So for those that replaced flywheel/clutch in an 18+...any issues with noise on lightweight flywheels?

I would ABSOLUTELY do it again. It drives way better and feels way more alive, I just want to make sure that 8k RPMs isn’t going to throw something through the block. Lol

Kinda like the car lost 500 lbs, right?

It’s amazing how much difference it made. It even changed the way the car sounds. I knew it would make a big difference but it’s way more than I expected.

8K on the stock valve springs... I dunno about how long that's going to hold up.

 

[Mustang_Lou]

Yeah without the stock dual mass flywheel, I'd play it safe too. Add the fact that you're supercharged and it supports that decision even more.

Okay so what else would you do to make sure it’s safe at 8k? I’m having it retuned and I’m dropping the rev limiter to 7500. Is that safe RPM.

7500 should be good, just a gut feeling at this point. If you want to go above that, obviously a good set of OPG's and crank sprocket, Triangle Speed Shop are probably the best out there right now. I would upgrade to a set of PAC springs if you want to turn it above 7500. It doesn't have a lot of miles on it, but the engine IS 9+ years old.

Good information brother. I appreciate it

Lesson I've learned the hard way with modding is don't be greedy and always want more and more.

Unless you're racing that extra 500 rpm is just not usable IMO.

I just want to make sure the car is safe to have fun in. I’m not doing much other that e85 performance wise. Now it’s about making the car capable of handling the power it has now. It’s a summer toy that will only have 5-6k miles a year put on it and I’ll spend more money on looks than anything.
