Isn't this mainly for AT cars, not really beneficial to MT's?

 

Since the Sun kit is just an ignition grounding system, you're saying that's all the HKW Twin Power ignition amplifier does too? Same setup, wiring, grounding points, etc...?

 

From what I understand, the Sun hyper force system is a passive system that absorbes ignition backlash from the coils. The HKS twin power DLI actually amplifies the spark to 1.5-2.0 times stronger than stock. It supposively allows you to runs wider plug gaps on FI setups, improves lower RPM throttle response, torque, and gas mileage, and improves the top end where the stock ignition may not provide enough spark. It's definately not cheap, but if you're running FI, I would think it might be a good investment to help avoid ignition misses at higher rpms.

Someone on the my350 forums contacted Sam @ Stillen, and quote: "From experience he said that I'm totally going to love the DLI twinpower with the stage4 and going to wonder why I haven't don't it before. About the biggest simple bolt-on increase they've seen with the s4. Better response, smoother and more clean power which surprised them because they thought the stock ignition was plenty strong. The DLI extends the duration of the spark as well as magnifies it."

Here's some brief info on it.
The Twin Power ignition amplifier incorporates both the CDI and transistor method ignition to provide optimum spark duration and maximum voltage output, resulting in crisper throttle response and a smoother engine powerband. The CDI method, capacity discharge ignition, provides maximum voltage by transferring all stored energy in the capacitor to the ignition coil so that the ignition current can buildup quickly, thus making the Twin Power very effective in the higher revs where a normal spark would tend to diminish. This strong rapid spark prevents the high rpm ignition miss that reduces peak power. The transistorized method generates high voltage by using transistors to cut off current to the coil, thus allowing for a long energy discharge. This longer spark duration allows the Twin Power to improve lower RPM throttle response and torque. The combination of the CDI and the transistor method incorporates two distinct systems into one high performance unit, hence the designation of Twin Power. The Twin Power produces a spark output that is typically 1.5-2.5 stronger than of the stock ignition system and consumes about 35% less power input than other ignition amplifiers. Each compact and attractive Twin power unit is constructed of durable anodized aluminum and sealed to prevent corrosion from moisture. General wiring harnesses are included in each unit to aid in installation and mounting. Vehicle Specific wiring harnesses are also available for certain models to further aid in installations that require intricate integration.(CARB E.O. # D-186-22)

Dimensions: All Twin Power Units, except for DLI II, are 91mm (L) x 80mm (W) x 34.5mm (H) and weighs Approximately 430g (~15.2oz)

 

You're confusing ground wire kits with ignition amplifiers. Amplifiers do a nice job over the entire rpm range, especially high, regardless if it's manual or auto.

 

No it's good for both.

 

The most I have seen on the two comes from the Evo guys. They have seen very good results with the Sun but do agree the HKS is a little better. For the kind of boost I run the Sun will show the same gains as the HKS.

As for using it with the Stillen SC, I can't say. I know that I had some detonation problems with my stage 4 due to all the heat out here in AZ but a water/meth fixed most of that.

 

I had it on mine too....Stillen (Sam) strongly recommended this product

 

so far so good,i,ve noticed a gas mileage increase and throttle responce is much better.i was only getting about 260 miles from a tank cause i live so close to where i work that the car really never gets warm enough.now im getting a little over 290 per tank and remember this is no highway driving either.i want to see what will happen with a lot of highway driving.

 

Damn, that's still less than 15 mpg. Did you regap the plugs?

 

yea new plugs gapped wider,but i live 8 minutes from where i work so thats the problem.i have to get some highway driving in to see what kinda mileage ill see.the mid a section on my350z and the national g club has a good skyline drive coming up on april 15th so thats when ill find out.

 

I just bought a HKS DLI, 470 shipped. to me. its a nice looking unit. I know the one i got comes with a direct plug harness. I have FI. and i hope it makes a little diference. I might throw it on this weekend if i get a chance. I use a MSD 7AL-3 in my race car and i know that works well... but this i belive isnt a "multiple discharge style spark output" correct me if i may be wrong....
Id like to see more input on this from others... after all HKS stuff is pricey but its also quality....IMO. u get what you pay for. im expecting happyness with i put it on.. if not it'll look neat at least haha.

 

Any more updates?

 

I'd like some updates too. Interested in picking one of these up.

 

I just bought the twinpower dli i wanted to know if there is a certain way the wireharness plugs in for example what plug goes to cyl 1 or 2 etc

 

I installed Plasma Direct coils. I didn't really notice any changes in performance or mileage - but I did a bunch of other stuff at the same time so it's hard to say.

Can you re-gap Iridium plugs??? I tried once and had to replace the plug - they're pretty delicate - be careful.
