Hks Twin Power Cdi System - Anyone Have One ?

[itbmils]

All

I have an R32 GTR - with the basic mods - pulling ~300awkw @ 18psi running R34 n1s

I'm having some problems with ignition break down (old coil packs) - so I plan to upgrade to Splitfire coils ASAP

I just wanted to know if anyone has used the new HKS Twin Power (CDI+Transistor) system

available from nengun

does this look like a work while upgrade

you wont need it unless your going over ~370rwkw as a rough stab.

the stock gear handles it fine, if your changing to new coil packs that will be enough

Just bumping an old thread

Is there any real benefit from having a bigger spark on an engine? I thought it would mean a better burn of the petrol, and the ability to run a larger plug gap?

Surely there must be some benefits?

Is anyone running one, and have they noticed any differences?

edit - found an old post from SK

we use the standard coils up to 650 bhp (400 rwkw), no problems, with plug gaps at 0.8 mm. For over 700 bhp we use the Motec CDI unit with Mercury Outboard coils as they are designed to be used with CDI.

BTW, CDI is not an amplifier of the spark, it provides a multiple firing of the coil for each ignition, not one, single, long spark as is standard (non CDI). Consequently you need a coil that is specifically designed to be fired in multiples, very rapidly.

So CDI with standard coils is pretty much a waste of money and if you are under 650 bhp I wouldn't worry about changing from the standard setup anyway, provided it is in good condition of course.

Hope that helps

Are you saying the hks cdi system is a waste of money with splitfires on r32gtst SK?
