Ignition coil upgrades

I have a Vortech not a vortex.

with a active solution rather than a passive solution. You could have gotten beter response with a slighter longer intake thanks to the insert of the vane.

My money is on electric superchargers. Easy to install and gives you the boost you want.

Just me.

Hi Guys, the one I have bought is called the Velocity Tuner!! Is this the same or very similar to yours DISCO.... They are stating that it will deliver 31% better fuel and 16% more HP, even 16% would be very definable. Should be here in a week or so, will post results then.

Craig, those things are about worthless, and a waste of money. The only way you can get any improvement from them is if you're in lab conditions feeding the engine pure oxygen at optimal temperature. They have no effect in the real world. Disco is right, you'd get more of a performance increase from buying beer and attempting to dance.

Cheers for that mate, im going to grab one of the electric superchargers from e-Bay, see if thats a better option

Ignore all the ones with the squirrel cage fans.

Ignore most of the supercharger kits on eBay. They are crap. They are not made to push all that air into your intake. I would also upgrade all the ducting to take 10 to 15 psi additional pressure so nothing leaks or blows out.

What bothers me is nobody bothers to make a circuit to slow the blower down during idle and then spin up when you get the gas. I guess they don't mind running around with something that sounds like a dental drill or leave blower at high speed.

As for those geniuses that think the prop gets in the way when it is stopped, that is what happens when you put those stationary vanes in the intake. Mainly, nothing.

Below is a Thomas Knight electric super install on a import. See it on the third post on Google. Goes about $1300. Has layaway and Paypal and great reviews from a few groups.

On the Stacker ignition add-on,if anyone has done it on a Rover, lets hear from you. Inquiring minds (and sheep) want to know.

Well you learn something new every day....I didn't know that you could get electric superchargers, anyhow here's my opinion. The first thing I noticed was that you need to lug around extra batteries to make it work, particularily Odyssey, which I think are crap. I have 5 dead ones sitting in my garage which someday I have time I'll try to resurrect. The next thing I noticed was that the boost rating is only 5 psi on the standard model, suitable for up to 3L engines. If you try to run this unit on a 4L 0r 4.6L engine your boost level will drop to around 3.75 psi, which is still okay but dissapointing, and, you cannot decrease the pulley size to try and compensate as this will burn out the supercharger. If you go for the upmarket unit, you need to have done major engine modifications such as forged pistons etc, plus lug around more batteries. Now if you study the picture carefully, you will notice there is no air flow meter. This because the system is controlled by a ECU such as Haltech or Motec. These also control the RPM's.

Now considering the cost of the unit, installation, extra batteries (and finding a place to put them), plus cost of ECU and programming, I'd be inclined to stay with the conventional Roots or centrifugal supercharger where you have the power available on demand all the time.

From what I understand the units only come into play when you flick the switch on, ie you control manualy the on/off of these units. WOT = Wide open throtle, this is when best to use them and turn it off after you slow or start to slow down....

I wrote an email to see what luck and effort the gent has had with his version of an electric supercharger on larger displacement engines. He has used this in domestic and import platforms and I , for one, would be interested what he has done for a similar stock 4.0L.

Yes, the electric supercharger is intended for WOT, but I see it more of something you only need when you need the additional horsepower. Who needs nitro or 20 more hp when you are in city traffic or for that matter, parking?

Conventional superchargers are on all the time and are thus not needed most of the time. Turbochargers are very much more involved since you are tapping into exhaust and doing intercoolers and have to deal with issues such as turbo lag and turbo timers to let that turbo spin down properly.

The electric supercharger is intended much as NOS or the MadMax A/C clutch on the Roots supercharger; when you need it or want it.

I also see it as something I would have to pull out when I do the annual state inspection. It looks like An inspection no-no. I also think it would fit perfectly in the space of the factory airbox. I could also get another airbox and hide it in there.

BTW, that supercharger in the photo was a pull from an aircraft engine.

You might want to take a look again at that photo.

That is a stock distributor, not a third party ECU install.

Look at the wire harness coming out of the distributor. No additional wiring for the third-party ignition. No addon post for the CD ignition. No rebuilt cap. That is that import OEM ignition with the stupid coil built into the distributor.

That is just what it is, a stock engine without even fancy ignition wires, with that e-supercharger just dropped in there.

Wow. Or as they say, in the Lower East Side , OY!

It's not quite that simple. Have you considered that in the event you don't run a micro-fueller to supply the extra fuel needed when you engage the blower, your going to have to run a high as possible octane fuel all the time, and if your motor starts pinking in the higher rev range, even run a richer fuel setting, requiring more frequent plug changes.

Just paid for my setup so as soon as I have it here and installed ill post the findings in the new year. Main reason for me needing/wanting one is for when im towing, most of the time im flat out up kinda steep hills that tend to go on for about 5-10kms and the old 3.5 engine tends to struggle a bit. The weight inc the trailer will be arround the 3 ton mark!!!!

I wrote an quick email and got a response, which I am sharing here:

I wonder how your product would work under my circumstances. I am
looking for a modest boost for street purposes. Any information you
might have and pricing would be invaluable.

Adam Vazquez

I AM WELL VERSED IN THE 215 BUICK/ROVER, AND HAVE BUILT SEVERAL HIGH HP VERSIONS--BOTH 3.5, 3.9, AND 4.4 LITER WITH THE 300 ALUMINUM HEADS AND CRANK IN IT. OUR 2006 MODEL (ESC-550) WILL BE PERFECT.

HERE IS SOME INFO:


OUR 2006 MODEL ESCH WILL BE AVAILABLE IN 60-90 DAYS. IT WILL GIVE 5 PSI BOOST ON ENGINES UP TO 6.0 LITERS, OR UP TO 15 PSI ON SMALLER ENGINES. THE UNIT WILL BE $1995 FOR THE SUPERCHARGER AND CONTROLLER. IT WILL FEATURE A HIGH EFFICIENCY MOTOR CAPABLE OF UP TO 25HP AND A DIGITAL CONTROLLER ALLOWING THE THROTTLE POSITION SENSOR TO ACTIVATE IT, AND EITHER KNOB ADJUSTMENTS OR LAPTOP PROGRAMMED CONTROLS FOR THE RPM, IT COMES ON, ETC. THERE WILL BE AN ADDITIONAL $500 IN BATTERIES, CABLES, ETC REQUIRED. THIS DESIGN IS ULTRA-HIGH-TECH, AND WILL REVOLUTIONIZE THE PERFORMANCE WORLD BECAUSE THE MOTOR IS 90% EFFICIENT MEANING THERE IS VIRTUALLY NO HEAT LOSS (STANDARD MOTORS ARE 50%-65% EFFICIENT). WE ARE MAINLY DEVELOPING IT FOR RV OWNERS AS WELL AS PICKUP TRUCK OWNERS FOR TOWING. THE COPPER-CORE MOTORS HAVE AN OPTIONAL FAN-COOLING SYSTEM FOR EXTENDED USE (LIKE AN RV PULLING A GRADE ON A MOUNTAIN FOR 10 MINUTES, ETC). INSTALLATION WILL BE QUITE SIMPLE. I AM PLACING YOU INTO A FOLDER FOR NOTIFICATION ONCE IT IS READY.

Very interesting Adam, it explains how the thing is controlled. Will you be getting one?

I couldn't find any mention of it during a search. Is it a device you stick into the air intake?
