As I mentioned in webcarconnection's Iridium thread, I have recently installed the HKS Ignition and Iridium Spark plugs from Denso (thanks to superchargersonline.com for the plugs and Intense Motorsport for the Ignition). The install was done by Dynocomp in Scottsdale, AZ. If any of you guys in AZ are thinking about getting some real professional work done on your cars, look no further than Dynocomp. They had really made the job look like it was done by NMC; they retaped all of the wiring so that it melds right in with the car and the ignition is mounted in an area where you can't even see it.

The entire install had taken about 2.5 hours, and it was worth the entire wait. I'll be planning on doing more work with them in the future.

Alright, now that the plugs are out of the way, let me get to the review. In a word, smooth. That's how I describe the car after the plugs and ignition were installed. You can definitely feel more power from the car as it goes through the first 3000 rpms of the car, and feel the power throughout the entire band. That's the beauty of having an ignition installed on your car: with some mods you only get top end power while with other mods you get bottom end power, but with an ignition you can an increase in power throughout the entire powerband. While the grounding kit gave a little crispness and response, the ignition fully distributes the electrical current so that every aspect of the car is more responsive by making the current stronger. I highly recommend the Twin Power ignition to anyone who is looking for a true mod that will provide immediate results that you can be satisfied with.

After I had the ignition installed, I also put my car on the dyno. Once again I didn't have a baseline dyno like at the previous dyno from Technodyne, but a stock dyno from another Z was used as a baseline. Now before you purists who scream and shout that I shouldn't use another person's dyno because the car's are different, shush. If you have a problem with this, then you can contact Richard Garcia, owner of Dynocomp and voice your concerns with him. Once again, I trust his assessment because he's been working in the auto industry for years, and recently quit the semiconductor industry to start his own business. With that said here is my graph. As you can see I gained over 20 hp/ 20 ft.lb. torque over stock. I don't have a dyno to show the gains after I installed the ignition, but overall I am happy with the gains of my car.

 

sounds good, as long as your happy with it, how much was the HKS Ignition and Iridium Spark plugs from Denso

 

The Ignition was $500 and the plugs were like $80 for six.

 

20HP gain for spark plugs and ignition?
Im gonna need a baseline from the same car to buy into this one.
Not to discredit this mod, its just i want a verified gain of 20HP.
It would be nice for an instant 20HP gain tho!

BTW--how much?

 

One question. Was the car used for baseline also have the injen CAI, Cat back, and the Borla header? From the graph, it looks like you have the CAI, Cat back and header. So if the baseline's car did not have all these mod, the spark plugs and ignition do not give much HP gain.

 

If you re-read the dyno, it tells you that he's got Borla headers, no cats, injen exhaust, and a grounding kit along with his ignition mods. I would think that the ignition mod gave him no more than 3hp but did help smooth out the powerband.

 

can you post a pic of where you mounted the ignition?

thanks,
victor

 

They mounted it where the stock airbox goes.

Hey cbsuper, you interested in a VQ35 Dyno Shootout at DynoComp? I've been trying to set one up, but cant find a free Saturday. I think Nov. 8th might be good for me. The 8th is a Saturday Drags at Firebird also, so maybe we could get a group to do both. What do you think???

Considering that stock cars run from 210-250 base, how the hell is that dyno worth anything?

Yeh, i know you told us to stfu but seriously. Whats the point of the dyno again?

 

I believe this to be a fair comparison. I agree that the dynos are from different cars, which will vary some in performance. But all other variables are constant. These dynos were done on the same dynamometer, both done by Richard Garcia, I'm sure. Since he setup both cars, I'm sure they were both setup the same as far as ramp rate and other variables. Finally, the dyno corrects for atmospheric conditions (temp, pressure, ...). How much variability do you think there is among 350Z's measured on the same dyno, which has been setup exactly the same every time. I guarantee you it's not 40hp.

 

Well, dynos can be very misleading and we have proof of that with several posters who have used the Mustang Dyno. As Richard had explained to me, and no doubt some of you may already know, dynos test in several different ways and readouts can be different based upon the dyno used.

That said, don't pay attention to what I'm putting down. Several good things can be seen from the graph. For starters, I think this finally puts to rest that the ECU does not negate mods. As someone mentioned before, I don't think the ignition is giving that much hp, but it is something that is spread across the entire band.

350Z 2+2, any day is fine for me. I'm currently out of the job market so any day that works for you will work for me. Except for Wednesday now that the new season of Smallville and Angel is underway. And you're correct, they mounted the ignition near the airbox.

Okay, I can't post the pics because the byte size is too large, but if you want to see them I'll be happy to e-mail them to you.

 

Even if their was a 5 or 10 HP difference its not the best way to show gains for a mod.
Also was your car modded exaclty like the car you used for the baseline?

 

Actually it's cbsuper's car not mine. Also, I never claimed that what he posted was ideal, nor did he. His original post had a couple of disclaimers stating such. I just merely added that it's not as bad as it sounds. Most other variables have been accounted for.

As far as the mods go, the baseline one was bone stock. So, the results cb showed were for all of his mods, not just the ignition/plugs.

 

"350Z 2+2 ??? "




I was thinking about getting my car dynoed over at dynocomp befor I did some things to my car do you know their prices are for a couple of pulls?

 

I think he just upped his rates. I believe that they are now $85 per half hour for 2wd. Since setup time is minimal, you could get 3-4 pulls for that rate. There is an extra charge if you want A/F ratio, EGT, intake temp or other things monitored.

It seems like these are still competitive with other dyno shops around and I think once you see his shop and talk with Richard, Ken or Joe, you'll be going back for all of your performance needs.

It looks like I'm going to set up a VQ35 Dyno Day on Nov 8th. You might want to wait for that. I think if you dyno then it'll be $65 instead of $85. We might head off to Firebird Raceway to do some 1/4 mile passes after that. I'll make a post in a week or so with more details.

 

Jesus!!! $85 for 3 runs... you have to move to PR its just $35 for 3 runs!

 

"350Z 2+2 ???"

Let me know when you are going to set up the dyno day! I will be there for sure!! Firebird sounds fun too! Please let me know when you guys are doing all this I would love to meet up with some other z/g guys!

 

Just the labor rate for a half hour is more than $35. How are you getting that kind of deal???

I figure that half of that $85 is labor and the other half is going toward paying off a $100,000 dynamometer. Sounds fair to me.

 

All begin a few years ago when a friend of mine bought the first Dynojet in the Island and he start charging people $35 and all the other shops have NO choice to charge the same... in other words luck I guess!
