For those who share an admiration for the 512M, here's a video I recently found. http://www2.csc.ne.jp/~ferrari/512trone1.mpg Notice how the driver must press the throttle while shifting to keep revs from dropping too quickly before clutch is re-engaged, the 512M's revised lighter rotating components make for quick rev ups and downs! For comparaison purposes, here's a similar video with a 512TR, notice how revs drop much slower on shifts. Enjoy! http://www2.csc.ne.jp/~ferrari/512trkida.mpg If you have a 512M video, please let me know! Regards, Bruckner
Bruckner, Thanks for the links. Those were great. Tubi or no Tubi? What does everybody think? Robb Williamson Centennial, Colorado www.williamsonimages.com
I have one, I have to find it. Oh and as for the F512M, as you can see in my profile, well its the one I want.
I saw these links last year when I ordered my Tubi. There used to be another link that was associated with these that showed the cars on a Dyno before and after the Tubi's were installed. I can't remember which country this was in but it may have been Japan. By the way, my Tubi didn't turn out nearly as loud as these are.
If you shift fast enough, the revs will be perfect when you upshift a gear in a fcar. You really have to shift FAST though or they will drop below their best point. The F512M *seems* to drop so fast that you actually have to blip to keep them up!
Cobrakid, I do match revs with as much precision as possible, on the vast majority of cars you don't need to blip the throttle on shifts because the rev drops are engineered to provide enough time for a clean shift, in which case by the time you're done shifting and re-engage the clutch, engine and transaxle speed are the same, thus matching revs. The rate of acceleration and deceleration of revs is engineered through rotating mass, mainly the flywheel, pressure plate and crankshaft. With lighter rotating components, as in the F512M, less energy is stored in these parts, allowing much faster acceleration of revs out of gear, and less rotating mass will also allow an equally faster deceleration of revs. For this reason, on the 512M by the time you're done shifting the engine may be down to idle speed, a throttle blip is mandatory, unless you can shift fast enough. Lighter rotating mass also means more power on acceleration, less energy being needed to spin up the flywheel/crankshaft. I provided the two movies for comparaison purposes, listen to the regular TR engine sound as revs drop during shift, it's slow, almost a full second to go from 7000 to 4500RPM in first gear, no need for a throttle blip. The 512M also sounds faster, with a quicker run up. Regards, Bruckner
I'm very interested in seeing those videos... Do you still have them? I have 2 512M sounds and one 512M video on my computer, but I can't host them or find the links...
I'd be very interested in getting any 512M related stuff, perhaps someone can host these vids/sound files? Another 512M video is available on www.scuderiasystems.com however download requires a password. Regards, Bruckner
Yep, thats the video I've got I must have quite a load of 512M vids made by myself too, but I gotta search for them on my HD...
I didn't save the videos, I just played them. It seems like they are a Tubi distributor in Japan or something along those lines.
I think I know which you mean then, but thats only 'after' videos, where were the 'before' ones then? On the same page?
http://www2.csc.ne.jp/~ferrari/shuuonkai.htm Try this link from that same Web site. There are some mpgs here. Just scroll down a bit and you will see them. The site is in Japanese but you can probably make out what's what.
Rico, if you do find 512M vids, would you mind putting them up on your website? I'm sure many enthusiasts would appreciate this! Thanks! Regards, Bruckner
Do you think this could be him "double clutching" on the upshift, and not just him blipping the throttle?
"Do you think this could be him "double clutching" on the upshift, and not just him blipping the throttle?" Whether or not he's double clutching, he's definitely blipping the throttle! Now the question you're asking is why he's blipping, he's either not shifting fast enough to hook up in the right rev band (revs dropping too fast due to low rotational mass) or perhaps double clutching although I can't see why you would want to double clutch in a modern automobile, the F512 is surely capable of taking straight shifts.

My Dad has a 360 Modena and I have a 348. My experience with driving these two Ferraris is that the RPMs drop INSTANTANEOUSLY upon engagement of the clutch--especially on the 360. However, I am able to shift quickly enough in either Ferrari to get a perfectly smooth transition from a lower to a higher gear. Of all the cars I've driven--Porsches, Acuras NSX, BMWs, and countless others with manual transmissions--there is always a little jerking no matter how well I would shift. Maybe it was because the RPMs couldn't fall quickly enough for my shifting. However, the Ferrari (and I suppose the Lamoborghini) transmission is, in my view, the only manual transmission on a production car that allows for a perfectly smooth upshift with no jerking whatsoever if done properly. They require speedy shifting. So, I say: why does this guy with the F512M need to blip the throttle up when shifting to the higher gear? Is he not quick enough with the shifter? I don't understand the point of blipping while upshifting.
No, no matter how quick you are with the shifter, the rpms fall faster. Thus even if you are lightning fast, the rpms are still too low for a smooth shift into the next gear. Thus the clutch will make up the difference and a slight jerk will result. blipping puts the rpms where they need to be. God I love that car.
I tell ya, I don't believe it! I mean... --I just don't believe it. I think a lightning fast shift should do the trick... I guess I'd have to take a ride in one or drive one. Is this F512M transmission THAT much different than the 360 transmission? The Italians never surprise me, but why would they put a transmission on the F512M that is not very usable? Any F512M owners want to testify?
