I recently installed a twin power on my car and I honestly cannot believe the difference it has made. The throttle response is MUCH crisper... and those little stumbles I use to get on occasion with 4th gear pulls are gone. This little thing REALLY smooths out the pull at higher RPMs. If you are experiencing missing at higher boost (18-19 psi on pump gas) and higher RPMs ... you should seriously consider the Twin Power.

I am VERY happy with this purchase... thanks to Billy Cha for being so easy to deal with for his used Twin Power.

Yes, I can agree with you, which is why I can't understand why people think that HKS is over rated and overpriced. If you have reduced your sparkplug gap previously, you may now want to open it up a little more.

hey Jim,

How hard was it to install and which one did u get?

Thanks,
Sid
WOTM.com has the install in their TECH section. Very simple, 7 wires need spliced into existing ignitor harness, and one needs grounded.

I had my plugs at .035 and would get a bit of break-up towards the upper RPMs at 18-19 psi. After the install.. it pulled clean and smooth all the way to redline... still at .035 and 18-19 psi.

Had I known how much of a diff it would make I would have done this a LONG time ago... but they don't show up in the forsale section often... and I didn't want to buy a new one. But I still think it's worth the $500 after trying it out myself.

Sid,

I went with the HKS Twin Power the install was very easy as Monster said. Go to wotm.com and follow their directions.. can't go wrong! The only hard part is making it look pretty and concealing the unit. It took me about 2 hours.. but I was being very anal about everything. You wouldn't even know it was installed unless I showed you where to look.

E-mail me if you have any other questions.

Jim

Congrats,

I tried to buy it from him, but I guess my cheap ass low-balled him too much. :p

BTW, how old are your coilpacks Jim?

Hahaha... I missed out on Walsers Twin Power a few months back because I low-balled him by $50! I really wanted one so I figured that $350 is still quite a bit better than $500.

My coil packs are fairly new... Jarrett said he replaced them when the new motor went it. I don't think it's just my car that has had these issues with high boost.... it seems that there are several people who have e-mailed me who said they had the exact same problem... some with 1997 cars with under 40k miles!!

Oh well... jump on the next one Ryan... you won't be disappointed. Don't be such a cheap-ass! hahaha

Damn I want one now... Unfortunately those little white pieces of plastic on my coil-pack clips broke.. so now I think Ishould replace those first... I doubt I have a 100% perfect contact with the wires now..so I hope that doesnt cause missing at all... no problems SO FAR...

Jim,

Wow, you are still running a 0.035" gap? How high have you boosted with the single turbo? I took SP's advice and gapped my NGK's at 0.028" because I got horrendous misfires above 21 lbs but idle is very rough at the moment. I will also get a Twin Power and think I'm going to try a bigger gap after that.

Besides the rougher idle (which might disappear when the Twin Power is installed), are there any other drawbacks to running a small gap?

I can't help it, its just in my nature. I guess he thought that $300 shipped was too low. :p

Yeah... I am all about low-balling too... most of the times it works! :)

I have new coil packs installed and have been running .044 on stock compatible AC Delco pugs and haven’t had any problems running 18-21 psi. I was at Vegas 2001 and was running great at the track and dyno 380rwhp on 91 pumped gas.

Flavio,

I use to run .032 I decided to try .035 since Steve Jarvis said he hasn't had any issues with that large a gap. So I did.. and I didn't really notice much difference over the .032.

A smaller gap should make a bit less power... in theory. :)

Are you running 21 psi on pump gas? If so it's probably your fuel more than it is the gap.

But yes the Twin Power smoothed the idle as well. Give it a try if you want. It made a big diff in my car. :)

Jim,

Normally I won't go over 21lbs on pump gas in everyday driving. If I do plan to go over that I usually throw in one or two bottles of octane booster. Race gas is very hard to find and very expensive. What gap would you recommend if I don't want misfires at 29-30lbs on high octane gas?

Don't know... I've never boosted that high. But that should change in the not too distant future! ;)

From what I hear .032 is good... but that's all hear-say... you know how that goes. I'd call Larry at SP for better advice.

Can you post of pic of the install Jim?
Ced,

I will... but I don't have my digital camera with me. I'll try to get some for you in the next few days.

Any of you guys ever try the B&M power plus. I think it is a little cheaper that the HKS unit.

I've tried both; the B&M doesn't address the problem properly. The Twin Power approaches the problem differently, and noticeably more effective. I have a B&M for sale, real cheap if anyone is interested! :D
