hks twin power,

or the

xs power pack

I realize the twin power produces spark to both leading and trailing, but wasent it shown that running without trailing plugs didnt make a difference as far as power?

It looks to me like they all do the same thing, but the ones that cost 200$ more have numbers to back up their talk unlike the 60$ one which just says "offers a 50% increase in power"

has anyone actually tried the Nology powercore? not much turned up when i searched.

 

The HKS is plug and play, does both leading and trailing and won't burn out your coils. I don't put much faith in anything from Nology. Isn't the XS just a rebranded B&M?
There's also the AEM which was supposed to be the best but had a lot of problems.

 

I recently had this conversation with my mechanic (scott at mazsport) and he reccomended the "Jacob’s rotary FC1000 " (rx7.com), as it actually boosts the spark power, as the HKS just does a "waste spark" type thing, and make the plugs fire rapidly a few times afterwards, not actually increasing power.

 

I heard that ignition almplification is important when you are boosting over like 15 lbs. of boost.... if you are running stock levels I heard that you don't even need one. My 2 cents...

 

the stock ignition works great up to approx 400 rwhp. if you are making less than 400 spend your money on something else.

Unless you have pre-tuned ECU that runs too rich. Then you need an amp also. HKS TP was reported to help immensly on M2Stage3 ECUs that run very rich up top.

 

HKS twin, the only way to go from what i hear.
