Ignition for 400whp
Hay guys,
About to have the car retuned to about 400whp when I install the new fuel system and am wondering what I need to do to the ignition to support this power level?
Car:
FD street port 13B
single turbo,
PFC
All supporting mods

Some have done it with the stock ignition. I have the HKS Twin Power. Many also use Crane or MSD boxes. Any good ignition amp will do and only needed for the leading plugs for 400hp.

I am NOT saying that the twin power doesn't work, but I am a little confused. If it has been proven that all it does is strike twice at lower RPMs, and increase dwell at higher, wouldn't a standalone that allows someone to set dwell times do just as well for the higher rpm (where ignition is a problem)?

the only reason Tweakgames is that anything over 450hp and that twinpower really isnt efficent. when steve kan came here to FL and alot of the people who had there twin power started blowing like skies. and it wasent pretty.
So
300-430 (safely) HKS twin power
430-490 (safely) Jacobs FC2000
500-600 (safely) MSD 6al
600+ & your going to need upgraded coils, distributors, wires, and another msd 6al box
but you choose, its your money afterall
I was here when steve kan tunned and 20% actually got there cars tunned without blowing something!

its a mixed bag on the twin power. for some reason an MSD 6AL box on the leading didn't work well for me (stock FC coils) and the twin power worked very well for a low 400whp setup. I've met a guy with a 600whp Supra running a twin power on stock coils. But I've also heard of the twin powers overheating (could also depend on engine bay placement) and oozing black gooey stuff.

The Jacobs has been known to burn out stock FD primary coils. That is why some of us use the FC leading coil on or FDs even if not running a Jacobs.

HKS now states that the TWINPOWER is made to work with resistor plugs. Previously they did not say that and many of us ran non-resistor plugs.
Luckily, I always mount my equipment in the coolest posible places. Must be my prior 7 years electronics experience in the USAF saving my butt more than once.
Any way this is the first time I heard of Steve burning up TWINPOWERS.

I'm making 512 and have a stock ignition with a twin power. Never had a problem in the two years i've been at this power level, or the 3 years before that where i was just a bit over 400. I have friends making over 500 as well with just a twinpower without any trouble.

I remember I had them set up incorrectly in my megasquirt and it woulden't rev over like 5500 rpm.

I think I'll be looking into the MSD 6al. There about $300 cheaper then the HKS Twinpower over here.
I can also get my hands on a new MSD 6al2 for a good price. Can the duel stage rev limiters be used in rotarys? (excuse my ignorance)
