signofinfinity.....9800 rpms?

sk8world, the HK$ twinpower acts as a double strike system on all three coils, it doesnt actually amp anything. Chris Ott over at rx7.com verified this with an oscilloscope. Running two wouldnt be of benefit from what I know.

Thanks Rich. Kinda what I thought but was wondering if it added any extra voltage. Sounds like it does not. I am going to keep the HKS unit. I ran it to 26psi this weekend and seemed fine.

hey Rich,

yep :D did the eccentric gear conversion..... high tensile toothed gears.... clearance e shaft and balanced rotating assembly.... it should be good up to 11000.... but i get the squeezy feeling... so i doubt i will rev 10000...

PS, i have seen it done on a stock motor.. 11500...

plus, the to4r is puny at 8800 and above... so its still pointless with my turbo....

gt42R with T6 is ideal..... but $$$$$$$$$$$$$$$$$$$$$$$$$$$hehe... later :D

Best

I've seen several HKS units go out due to heat. Although also susceptible, the Jacobs units seem to be a little more reliable.

I'm in the process of researching ignition break up solutions. I dynoed a month or so ago and couldn't build hp above 5500 rpm no matter how I tweaked the maps... Then I realized it's probably the ignition breaking up. Original coils, 10mm Magnacors and 9s all around on 14.5psi, the good news is it was at 389rwhp but the curve went down from 6-6800 (lifted cause there was no point). I have an aggressive KDR port and running a T-78.

This is a break-up problem right?

Is the problem the coils? If so, the HKS TP won't do anything, so do I have to replace coils as well? Thanks for the help.

I run both, i have twin power on the 93 and have no problems at all. I run two jacobs on my methonal motor and have no problems at all either. I would say you have problems of a diffrent nature.

"problems of a different nature." ??? Was that directed at me? Meaning it's not ignition??? I forgot to mention AFR was solid around 11.5 tapering to 11.0, but got wavy around the 5500 mark...

cant imagine it is the stock coils as Myself and others have run this setup with the HKS unit and made 500+on the dyno. However I am trying to figure some issues I started having above 22.5 psi with ignition. May have been my AFR were to rich (low 10s) and back to back pulls. Causing my plugs to fail?? I may just go the MSD route..

Im definitly no expert but timing and fuel are going to determine how well the ignition works. I just wanted to give you an opinion from some one who runs both, hks on 10.8 93 with stock coils, and pro 10 series ign. with ultra coils on methanol engine. If everything is ok they both work well, not a case of this ignnition wont work in this aplication. But when the tune was not right it all run like shit.

This past weekend I switched out my old school Jacobs amp and fc leading coil in favor of an almost new FD coil, new HKS twin power w/rotary harness, and a new oem ignition wiring harness. I also installed all new b10egv plugs.

I didn't get a chance to drive the car much, but I must say I'm impressed. throttle response seems improved, with more midrange power. Boost seems to build more quickly, and I get zero traction after 6k rpms in second gear. Of course, it's gotten colder here lately, which is affecting both the boost and traction issues. The car is definitely much smoother at lower rpms, I'm very happy with the unit thus far :icon_tup:

Im going to bring this one back from the dead. My 3rd gen is idling really rough, but when I pull the fuse to the Jocobs ignition it smooths the idle out does that meen my jacobs is going out?

I ran the twin power with my half bridge and pt76 on 26 psi and had no break up. Once installed the key thing is to make sure you have the unit properly grounded. We had some issue with the unit and found that grounding was so very important to it.

My FD had the TII coils for leading and the stock trailings installed when I bought it. When I got my Twin Power I didnt think about the harness being cut, so my new HKS harness was kinda useless.

Heres my question:

I now technically have 4 coils instead of the stock 3.

Do I just not connect the leading coils (TII) and connect just the two stock trailing coils...

or should I find another stock leading coil to run it with the full harness on the stock setup?

Would the stock coils be adequate with my HKS TP for a 70mm inducer BB turbo with a streetported motor, run by a microtech X4?

the HKS twin power will fire a 10.0 blend at 21psi on alcohol (E85) and 550rwhp.

Used to run the Jacobs unit but it has a rep for failing. And mine did actually fail. After I switched to the Twin Power I saw a 30-50 mile increase for a half tank of gas.

Hi and what about the AEM TWIN FIRE http://www.aempower.com/ViewCategory.aspx?CategoryID=78
