My question is this:

If I put these mods on my 06:

1. Motordyne 5/16" plenum spacer
2. Motordyne MREV2
3. Drop-in K&N filter

Do you think my engine will put out as much (or more?) power than a stock 08? The reason I ask is because I find myself wishing I had bought an 07/08 instead of my 06 because of the engine. I figure if I put a few bucks into power mods so that I am at least as powerful as an 07/08, I will feel better about my 06. I don't really want to do anything to the exhaust because I don't want to change the sound of the Z that much. Will this give me the power I want or will I need more? Thanks in advance.

 

Well, assuming you have the MT, the difference is about 10 horses more or less. If HP is your only measure, then those mods would get you there.

Bearing in mind, of course, there wasn't much difference to start with - probably not enough to worry about.

 

Do you mean that the 06 vs. 08 is only a 10hp difference? Or do you mean that those mods would give me about 10hp? I thought that there was a much more significant difference in power between the 06 & 08 because the way horsepower and tourque are measured was recently changed???

 

that's correct, if the 06 revups were measured under the new SAE guidelines they should come in somewhere around 285 HP, based on other models that were rated under both (acura 3.2L 270 > 258 for example). So the difference is actually more like 20 HP at the crank, the dyno results seem to substantiate this.

 

So under the new guidelines, an 06 would be at about 285 HP - what about tourque? Thanks.

 

I dont know, keep in mind 285 was just a guess based on what happened with some other engines, some actually dropped more and some were even rated higher.

i wouldn't worry about it too much, you are better off comparing some actual dyno results that have been posted here. My guess to your question however is no, the HR would probably still be faster.

 

Does everyone else agree with this; that the HR would still be faster?

I guess what I want to know is the minimum modifications (and which mods) I would have to do to my engine to get to about the same output as the HR. Thanks.

 

unless you plan on adding cams, then even with a few bolt ons you will not be faster than an hr. its a proven fact that bolt ons on the vq engines don't make that big of a difference

 

I may be of some assistance here...

Here is a Dyno comparison of my wife's 06 6MT with mods vs. my stock 07 6MT:

In this dyno, wife had:
Motordyne MREV2 lower collector
Motordyne 5/16ths spacer
Motordyne throttle body coolant bypass
All else stock:



Here is her car with Mdyne stuff, then plus bassani exhaust, then plus unichip and Dyno tune:



Here's my HR with Bassani exhaust, Stillen HFC, and injen Dual Coal air intakes. No tune yet: (notice the torque and HP curves are not lined up on this one - different scales on left and right)

 

^^speaks for itself

 

i have all of those plus the hks exhaust and turboxs test pipes....i dyno'd on the heart breaker at 248....my buddy with an 07 with just the hks dyno'd at 26x...

 

To hiz-n-herz:

I was just down at the shop (Z-Car Garage) and met you both yesterday...also watched Forbes run the dyno on your car. Very nice, and I have to say that is the best sounding Z I have heard yet. Sweet car!

WOW! This thread did not turn out the way I hoped it would Looks like I would need to get a laundry list of bolt-ons before I'd be in the HR range. When I bought my car I didn't plan on doing a lot of modifications, but the more I drive it, the more powerful I want it to be. I'm starting to think a supercharger might be nice

 

Vortech is what I am setting up for on my '06, just trying to do it the smart way and not throw stuff at it.

 

Thanks Derek! nice meeting you.

Rob's a genius. They installed the Bassani and it sounded great, but when I had them add the Stilllen HFC, it made crazy power but also some real nasty rasp. I was embarrassed to drive it down the street! Sounded like a badly tuned Civic! Rob said he could get rid of the rasp and few iterations of modifications later, the result is what you heard. I dunno how he did it, but I am very satisfied with the results. Took it out for some joy-rding tonight - very impressed with the sound and power! I broke the a$$ end of the car loose shifting from the top of 2nd into third. Traction control jumped in and flashed the SLIP light - heh no kidding. Unbelievable...

Yeah, Big Z, the SC is the way to go for DE power. I'd like to see the dynos for the SC'd rev-up DE to see how I measure up to that - prolly not al all. Do the math for all the bolt-ons and look at your power - then do the math for a SC and look at the power.

I agree that the 06 needs a little something - it's just not as fast as it looks like it should be. I had a Daytona Blue 06 for a year or so, but traded for the 07 after seeing the improvements in acceleration times for it. It's been a great base to build on.

I tried to talk Herz into a SC for her 06, but she has no interest in making that kind of power.

There's no CARB exempt FI out for the HR engine. Too bad we live in Cali.

Lovin the Z33!

 

Here is a overlay of my 03 and a HR engine same day same dyno..

I had every bolt on but cams.. Was able to make more TQ then the HR engine. The HR had exhaust, race pipes and intakes.

My car ran a 13.005 and the HR was able to hit a 12.9 down the 1/4

Dude unless you are actually racing in a track you are not gonna notice or even need that much hp to justify spending the dough. How about other mods in suspension or better tires/brakes... That would make more of a difference on the track.

If anythings its more psychological or perhaps you have not resolved your oedipal complex j/k.

 

I forget, but was your '03 tuned for the boltons? I'm guessing it probably was?...

 

Yeah, it was tuned with a UTEC..
