Rev Limter? Do we even have one?

[MPDano]

After listening to my new love for this Ferrari 355 and exhaust system. I have never heard a 928 hit it's Rev Limiter. Do we even have one besides the engine blowing up?

[Danglerb]

Yup, some have a thing I think in the distributor, others the brain, easy to find with the Euro S motor. One I think retards the spark a bunch, and other maybe turns off injectors, but can be diddled with sharktuner.

[MPDano]

The thing is, I never heard a Shark "hit" the Rev Limiter. Mike, you should do this with your Euro!

I actually toyed with the idea of getting a 355. (the price has come down A LOT). Then I talked to a guy that owned one.. it needs a $10k timing belt change at very short intervals (I want to say 12k miles bit I don't remember). oh, it's only $3k in parts if you want to pull the motor and do it youself. I drove away happy with my 928 again

[MPDano]

You have to pull the motor to do a TB?

[Pete R]

yup, mid engine.

oh yeah it is a lot harder than pulling a 928 engine. The engine, transmission, and rear suspension are all one piece that has to come out in one big and very heavy lump.... so you have a lot of weight, a lot of complexity, no space, a lot less documentation on how to do it than a 928, far more expensive parts, no non factory sources for many of the parts...around here the going rate for the engine R&R is $10k....PLUS parts. A friend bought a 1999 355 a couple of years ago, it had 7000 miles on it...first trip to the repair shop for a "post PPI" (bad concept but the car was so new and so cheap he took the chance) netted him the timing belt replacement, and all its associated costs.....and gave me the opportunity to look at the process in detail. My first opinion, before seeing what had to be done, was it can't be that difficult....WRONG! What a process...

Parts for Ferrari are extremely expensive! Clutch pressure plate and disk, $750, starter $1,900 new. Guy down the street from me has a 430, real nice but he has all work done for him. I was looking at a 308 until I priced out parts. With Ferrari you step into another level.

The 16v 928's have a rev limiter in the stock ignition rotor. It is spring loaded and breaks contact at high RPM. If you've replaced your stock rotor with an aftermarket piece, you no longer have a rev limiter.

[MPDano]

Here's a thread with someone replacing the TB with engine "in" car. Also, states that there was plenty of room in that area. It says to drop the tanks. Although no pics were taken.

Hi,to change belts in situ,remove fuel tank.Remove 2 engine mounting bolts and 2 gearbox mounting bolts.Engine can then be moved back 30-40mm.Then raise engine at front with hydraulic jack,this then allows you to loosen crankshaft sprocket.Access to the belts and tensioners etc is very restricted and I would not recommend this procedure for a belt(s) change.However it definately can be done!

Found some pics of tank remove and TB View

Is there a video of a 16v 928 hitting the Rev Limiter? Does it sound the same? Just curious.

[Pete R]

damn, I should have bought one, that looks like something I could do. It's nice to see that they get cranky on the Ferrari forum too

[tmpusfugit]

Looks a lot easier than dropping the engine/transmission/rear suspension....

[MPDano]

They do say it's a byotch to drop the tank, but then again, it's Ferarri guys talking, not 928 guys

Not sure about the later Euros, but the early Euros had the rev limiter in the rotor. If a US rotor has been installed, there will be no rev shut off. All US 928's have the rev limiter built into the ignition module to shut off the spark at about 6300 rpm.

...but what does it sound like? Does it just shut the ignition down and the car dies? Or does it sound like the Ferrari above and do intermittent cuts and just doesn't go above 6300 rpms?

[DPW928]

On the euro the ignition will cut off until the rpm decreases enough for the spring to close. I can't remember hitting the limiter on my US 928, but on my 931, the ignition shuts off until you lift the accelerator. Think it's tied into the WOT switch.

[R.Pires]

Hi,

I've reached the red zone once or twice and it's an intermittent cut until you lift the accelerator.
That cut is made by the distributor rotor. I've replaced mine a few months ago with an original one and this rotor it's a little different from a "normal" one.
