Hey all, just wondering if anyone has any REAL proof that the HKS Twinpower does anything at all. My guess is that it is just a capacitor.

I dont have any solid evidence to point too but I remember reading that with no mods or only slight modifications the HKS Twin Power made no or a very slight difference but on a heavily modified motor significant HP was gained between before and after testing and the top end a lot of the break up was cleaned up.

All that the twinpower does is interupt the signal and cause the coil to fire longer. Its hooked up in the signal line isnt it? What else can it do? You can adjust this same stuff on the wolf 3d 4.0.

According to HKS the Twin power is also a CDI. I would like to hear the voice of those with this. I'm thinking about going to this unit on my FC.

there is a big thread on this in the 3rd gen forum with a dyno chart from sleepr1...

why not ask him?

Well, i think it does work and works well. From one weekend to the next, with no other changes, I knocked .4 off my time at 75/80.

I was not payig a lot of attention to the weather from one week to the next, but I was pretty impressed at the time and emailed somebody about it.

ErineT said it made no difference to his car but it damn sure made a difference to mine, so it is possible that the twincoil helps to cover over an underlying problem - like maybe I had a weak coil?

Based on my experience though, I say get it. And install is 15 minutes if you have the harness too. Beats hell out of a whole new Crane or MSD ignition system as far as simplicity goes.

There Expensive. A friend of mine got one and i wanted to see what was inside before he installed it, to justify the cost and to see if it's made from quality parts, BUT HKS filled the case with black silicone.

I'm sure they had there reasons for it.

One to keep people from me opening it up and seeing exactly what they did.

And Two to prevent it from failure, from vibrations.

MSD's are also potted heavily (it's actually a potting compound, silicone can corrode electricals. At least I *hope* HKS is using potting compound and not silicone!)

Most consumer electronics are potted, actually. Even if it's just a thin layer sprayed on, the electronics generally are "sealed".

Back to the HKS... the MSD is also a capacitive discharge system.

Does the HKS fire multiple sparks? The downside of CDI is that the spark is much shorter in duration than a normal Kettering-type ignition spark. MSD gets around that by having multiple sparks.

If the HKS is more expensive than the equivalent MSD, go for the MSD...

I have one on my 3rd gen..

When I first put it on.. it made a nice noticeable difference.. my idle was smoother and the car in general ran much smoother..

One of the local guy was having issues with his MSD.. so, I asked him to try my HKS.. took it off in minutes and installed to his car in minutes (5 or so).. He also noticed a difference.. Idle and the pull.. especially higher RPM.. He ended up ordering one..

Another guy, here in town had idle and break up issue.. I let him borrow my HKS.. He tried it.. he ended up buying one.. So, I guess its worth 400+..
I've heard about it from talking with people at the Rotary Revolution last year.. Thing that I liked about it is the harness that plugs right in.. like i said, it took 5 minutes to install.

Thank you herblenny, a little first hand feed back really helps.

Thats cause he bought a defective used msd off Ebay.

You'd get the same (actually prob better) results with a new MSD for $120. The only thing about the MSD is you have to splice it to the wire instead of plug it.....but hey I can live with that to get the stronger spark and save about $400.

mazda found 8ps on there racing peri port motor with CDI over HEI

Hmm.. Defective.. but I remember it took many people trying to figure out if it was defective or not..

Finally the conclusion came about because after installing HKS Twinpower. I still stand behind HKS vs. MSD.. but like anything else, its all personal preference..

How is the AEM better?

SPOautos

Well, yea but thats just like any part that has issues. It didnt really take a lot of people to figure out if his box was defective, it took a lot of people to figure out what was wrong with the car in general. Some people suspected ignition and some suspected other things. Then you have to figure out what part of the ignition, was it coils, plugs, wires, then make sure the MSD is hooked up right. Then when all thats ok you just change out the box and see if that helps which it did.

It would be the same way no matter what amp was on it. You still trouble shoot an ignition problem the same.

My point was just that Leo's problem didnt stem from a problem with MSD amps in general. His problem was he bought one off Ebay that someone scammed him with by selling him one that didnt work.

The MSD6a is a very proven unit, they have sold millions and millions of them.

Because thats the one he bought!
The HKS works, period, do the other ones work?
Sure get what ever fits your budget. If you want a bunch of bulky MSD or Crane units under the hood there is nothing wrong with that!

SPOautos

You dont have to get a bunch....just one is pleanty

I made over 550rwhp on C16 and ran 10.32 on stock 2nd gen coils

Why the hell would you bother?

exactly

until someone like jimlab buys them all and evaluates, we can all BS about why "ours" is better
