and those pesky toyota Supras, 2yrs back did a 246mph run.

i bet even Toyota didnt know how good the Aerodynamics were at over 200.

 

hey howard a question, i don't think they make the fc3000 anymore what other ignition box works the same as the fc3000?

 

MSD HVC boxes have about the same specs.

 

Msd hvc what is the difference between this box and the msd 6al?

 

The new MSD Digital 6A offers 135 mj and 530 volts. I'm building my ignition around two of the new MSD 6A boxes (part# 6201) and the HVC 8253 coils which offer 44,000 Volts and 450 mA.

Should be in the same ballpark as the Jacobs setup Howard mentions above. The 8253 coils are *huge* though and I'm having trouble figuring out where to fit them on my road race FC to keep the plug wires short.

I like my M&W CDI >_>. One box, 4 coils, all of which are pretty small. 115 mj @ 480 Volts at the coil, up to 10,500 RPM. They have a drag race version also that does 250 mj @ 500 Volts but can only run for 30 minutes if I remember right before it shuts down from heat.

M&W can also build dual mode 250/115 mj boxes. Use with a MAP or TPS switch. Get the high power output when you need it, lower power when you don't.

 

I'm assuming that still would't work for road racing right?

you using the Pro 14R?

 

That you would want to ask M&W. The ones we have sold have been for street/strip cars, the obvious market. I've done quite a bit of sanctioned road racing, and a sprint race here in the states usually lasts around 30 minutes. So, I could see there being enough "rest" duty each lap to get the dual mode box to run long enough to complete a 30-45 minute sprint race without issue. That is a guess though. Now, if you're doing an endurance series (with races running 1hr+), that may be a different story. Again, that's conjecture and M&W would be the people you'd want to speak with.

All that said, there are inductive ignitions now putting down 100+ mj. We've used the Mercury coils with good results to 25+ psi on gasoline. IMO, the day is here where the complexity and expense of CDI is only needed with a lot of methanol and/or 30+ psi of boost. Inductive is cheaper, usually easier to wire, and there are no problems with the noise generated by the CDI. Haltech has a new 15 amp ignitor coming out that we're going to pair with some Bosch coils to test. On paper it looks like it should have an output in the 115 mj range without a CDI box.

 

IIRC, electromotive rates their single tower coils at 150mj. Whether thats accurate I don't know - I've never tested them. But even if its 20-30mj over rated, thats still very powerful without the extra boxes and wiring of a CDI.

 

Dynatek cdi boxes 189mj per coil

 

I like the dynatek, but just ended up wanting something that worked right of the bat with the rotary.

 

Yes.

Those are the Mercury IGN coils. AEM is now rebadging them and claim 118 mJ. Suffice it to say, they're hot. You'll need a high current driver to run them though.

 

They also sell then as a complete coil/igniter, 20 amp rated.

 

So whats happens with the turbos dyno charts?

 

Yep. That's the Mercury IGN-1A. Great coil!

 

After the one year anniversary last month the thread switched to Ignition tech.

 

So Howard any news?

We are waiting in anticipation

Howard is doing well, I talked to him recently. Just working on a rewiring his car. He Finally got fed up with all the little electrical gremlins plagueing his progress and decided to have it re done.

I was thinking about it the other day though,.. I think this thread is perfect because it shows everyone who hasn't taken on a project of this caliber.. what can and sometimes does happen. The unexpected will occur and you will run into problems. I think this thread is the perfect example of a big project.

 

Totally agree!! AS a perfect case in point, I'm still working through my latest Hey-why-don't-I-just-upgrade-my-EFI-and-ignition-system great idea... from FIVE years ago!

 

Even with the wait, I think others should appreciate someone else for even trying to take on this test. When this is all said and done, it is only going to help the community aid in a decision on what turbo will work best for their application.

for those complaining about time that it has taken, are most really out any money? Maybe if someone donated a turbo for the test could have some objections. Really though I think most people should appreciate someone trying to provide good info for others at the expense of their own time and money to help inform the Rotary community.

There has been some interesting info on Ignition systems as well.

Looking forward to the results for myself to help aid in choosing a turbo for my current project.

 

Kinda curious as to whatever happened with this undertaking. I happened across this thread while searching for something totally different but it caught my interest. Mostly just because HCs posts are always very informative and he is an inspiration to me since I'm also from wis. In my backwater town if you mention a rotary to some one their eyes just glaze over and you get a blank stair. So its nice to see some people in this state have the know how.
