@Roloster, or whatever your name is, I built my motor, it is to rally spec. Lots of good bits and carefull assembly. I've been building A series motors since 1966.

It gives peak power between 7000 and 7200. When I did track work it was with an 8200 rpmredline, but in the interests of the 40 year old Mk1 CooperS EN40B nitrided crank inside, I now limit it to 7500 electronically. Doesn't mean I rev it that far on the road, it's just insurance if I miss a gear. 
It has done nearly 15000 miles since rebuild, and it ain't broke yet.

ps. put your filter magnet on the OUTSIDE of the spin-on filter, it is less messy than inside and works fine.

That is what I have in my mini. I'm running a msd ignition box with my 123. The box I have has a plug to accept and use a rev limiter but I have picked one up. 

Not trying to be a smart a--, but for autocross I use my ears and' kind of' the seat of my pants as a rev limiter. I've never been able to look at my tach, and therefore don't even have one in my autocrosser. I'm sure a RL would be valuable for other applications.

You guys go ahead and blow your engines, you are rich guys.

Simply watching the tach is easier than guessing what to set a rev limiter at and even then it could still blow if your using the wrong oil like a lot of you guys seem to.  Like DRMINI how do you know 7500 is where you should stop?  The answer is none of us do.

Life is a hard teacher Catmaster,,,I hope you have some safe races without damage.

SXYMAN I never heard of putting wingnuts on the motor mounts, makes it hard to get a wrench on to tighten fully but that's what good old channel locks are for eh...????  Is that a Lotus thing maybe

Yeah, it drops random cylinders.  Usually I am busy turning or braking and  dont notice the limiter.  I get a little popping anyway at low rpm.

Don, at 5400 you must hit the limit once in awhile. What does it sound like. The soft touch drops random cyls. does not cause a back fire or other issues just a high speed miss. Steve (CTR)

PS we use 8800 on vintage cars and 9200 on autocross cars. 

I use Pertronix rev limiter and pertronix Ignitor II on my 1300 Inno Export that I autocross. It's set at 5400 to be safe.

I have used MSD soft touch on several race cars. They do use pug in pills. I have 4000 though 10000 by 100. I recently picked up a Pretronics limiter but have yet to use it. One knob for cyl select and one for RPM. Steve (CTR)

I now run a Powerspark electronic module in a 45D dizzy with the mech advance locked, in conjunction with an Accuspark stealth black box.
The Accuspark allows the advance curve and dwell to be programmed, it also includes a rev limiter. I set it at 7500 for street use.

Yes.

A number of cars did.

Not to go off topic, I was interested in buying a Lotus Esprit years ago. Lot's of phone calls, being put off, finally got the green light to come look at the car. Car looked good, asked about a test drive, only then I'm told it doesn't run. Centrifugal limiting rotor had failed, I offered to replace with a standard rotor (about 10% cost), owner said no. Lucky for me I walked away.

One of the best decisions I've ever made.

Fiats, lambo's (old), Ferrari's , some British and French cars had them. I don't remember ever seeing them on minis,sprites, etc.

On MSD units they have plug in limiters, I think they come with 3 or 4 of different RPM ranges, with others available.

Wish these were available years ago, I would not have had to help a friend swap so many engines in his W30 Olds 442.

Should have put wing nuts on the motor mounts. 

The Jensen Healey's had one and they ran a 25d dizzy i believe. I can't remember if you could adjust it or not as it was set high (for stock Mini use) around 7k from memory.

The Ignitor 3 has a limiter, here's a vid showing how to set it:

How about this one made by Pertronix?

I'm thinking about using this one with my Advanced Distributor recurved 59D.  I believe they're available from MM.  I've also seen them at JEGs and Summit Racing.

@ SXSMAN Your a Porsche man. Didn't early 911's have the rev limiter simply built into the rotor?

I've also seen MSD units used, although not sure of what dizzy they were running.

I have multiple 1-2-3 units in use and may try a pertronix unit on a distributor machine and get back to you. Send me a note at skinnersunion at Yahoo dot com and I will let you know what I learn.

Yes, I'm interested as well.  I believe the racers use external Mallory ignition boxes with that feature but I could be wrong.

What kind of experiences has anyone had with rev limiters?  Can anyone recommend one that is compatible with a 1-2-3 dizzy? For some reason I thought there would be one built into the 1-2-3. I reread the manual to learn how to set it, and nada! So, I would guess I need an electronic limiter that works off the distributor, although one that worked off the coil would be nice too, as I wouldn't have to mess with that $$ dizzy. Thanks!
