Im curious, has anyone else noticed how long it takes for revs to go down? is there a way to change that through ecu tuning, and would it be beneficial?

thanks,

I have noticed this too, If you ever hear a Carrera GT rev it rev's up and down very fast and man it sounds amazing, I wouldn't mind if my car did that

As for ways to make our car do that I would think lightweight internals, flywheel, crank pulley, and larger exhaust valves, maybe. I would think a cooper would have a better chance of doing this than a MCS, we dont have that big parasite know as a SC.

 

I don't know why you would want the car to rev down faster, and it takes as long as it does from motetum ECU tunnign won't effect it.

 

well, I would want it just cause it sounds cool

BUT, I was also curious if it might help at all on the track just so it would be worth doing.

 

There is no ECU program to make your revs drop fast or sound like a Carrera GT or F1 car. It is due to their engines having a really short stroke. You could maybe custom design an aftermarket cam with really round lobes, but in short answer, no it's not possible.

 

I can only see it hurting at the track (at least with my MCS) as it spinns down fast enough that on the upshift the revs are already matched, and on downshifts I'm blipping it up.

A light weight crank pulley would probably let it come down quicker as well as rev quicker, but its not something I feel the need to mess with. The crank pulley will help the revs climb quicker, and should be less rotational mass keeping the engine spinning as quickly. BUt it will not drop them in the manner a Carrera GT will, if you notice it at all.

 

well that answers that

thanks

 

im not sure... but would the car not slow down faster as well when letting off the throttle at a high rpm? BUT in this case possibly also wearing things down quicker

 

I'm getting lost in the question, spinning this up and slowing them down quicker will increase wear yes esp. since you;d be doing them more. But it also helps to have faith in your oil. From the GT door jamb...

 

oh dear, I used castrol...

:p

 

i worried about paying $50,000+ for a car and having bubbles in a little sticker talking about oil.....makes you wonder well at least me

 

1 thats off a of a 150k+ car, and 2 Mobil just downgraded their oil after an incident with Castrol. Yet another reason to buy the Ferrari instead.

 

Mmm, it would be nice having the REVs bounce up and down, a lighter flywheel will help that

 

Uhmm wrong and wrong sorry

Thats 250K and they dont make them anymore

Porsche recommends 0 - 40w and that is synthetic.

 

Even still I'll take the F430 over that

And if they aren't making them anymore then they're used cars so I can negotiate

Besides the poeple who buy those don't care about a measley $100k when it comes to the cost of the cars.

 

imagine putting 100k into a car like that

 

You need to go read the P-car forums

There are pics of ppl using Carrera GTs as "daily drivers"

Threads on "Is a F430 a good daily driver?"

I'm serious.

The bottom line is that to the very rich, a F430 is just another car ... it breaks down, you take the Lambo. Some ppl have incredible collections of cars and I'm not talking about Jay Leno ... just ppl you might never think.

BTW, for the OP, it dont matter how fast the RPM come down ... only how fast they go up

 

Ok is there a point? F430 is daily, GT is a daily, lambo is daily, around here I can even say the same for the DB9, Continental, M4, M5, M6, 7 series, Elise.

This is now A off topic and B you've got me lost as to it meaning .

 

??? I didnt bring up Carreras, I thought you did

 

The OP mentioned the sound I just posted a pic of the door Jamb

Just need some noise makers....

 

While we're on this subject, if anyone has either a Ferrari Dino or Daytona that is just collecting dust in their garage, I'd like to have it- I promise to ride often and let it run fast whenever it wants. I'm not picky about the color- any is fine. Looking forward to your donation. I like Ferraris... They're kind of fast. Oh, and they look kind of good, too. -Jeffy.

 

Well, it helps a lot with AutoX. Having it rev up a little faster means that there is less weight from the engine components/flywheel. You'll be losing a little acceleration because the momentum of those parts helps a lot in getting up to speed. The only real reason to even care, (besides sound) is rev matching. It helps with AutoX because quicker rev matching = quicker shifts into the corners. I have a 350z and I rev match at just about every stop. I have a pig of a flywheel, though. I'm going to be trading it for a Mini. I'm here to learn. Love the site!

 

I completely understand that, if you read the rest of that, I think the stock setup is already prefectly balanced for the time it takes to shift I'm very easily matched, now if I changed up to a short throw shifter and adjust the clutch pedal throw to be less I could see the need, just don't feel its nessacry on a near stock MCS.

 

a 350z is exactly what I had in mind when posting this I drove my cousins and it felt perfect.
