HP, 0 - 60, 1/4 Times (Results) - 2007 Infiniti M45 Sport

[Tony407]

In all honesty, what did you find so unbearable about the stock M45. Don't you thinkwith all of Nissans resources they crunched the numbers on air flow when producinga HIGH performance model. Even with the after market Exhaust, your numbers are imperceptible to the driving experience. I would suggest stop turning wrenches and drive this incredible automobile

Unbearable? Not at all. I've modded every car I've owned over the last several years. I enjoy it.

Imperceptible? I took a tenth of a second off my 0-60 times and 2 tenths off my 1/4 mile time. That's excellent results.

you can measure 0.1 sec but you cannot sense it when you drive.This is only in the eye of the beholder not in the seat of your pants.

to each their own. i think its really interesting the way he is modding his car. i mean, most car enthusiasts love modding cars and do it the right way, as tony has proven. yes the m45 has a great powerplant, but needless to say, for some, its just not enough.

Maybe I misunderstood you. I never meant to imply that I could feel physically feel the difference of a single mod like exhaust, intake, etc. I can't feel the difference with my butt, but I know that at the 1/4 finish line with a .2 sec improvement, I'd be about two car lengths ahead of stock M45. That's certainly perceptible enough, agreed?

tony you got me on the DRAG RACING. For all of you "drag racing" your belovedM45 listen up.

[m45Matt]

I did the same thing and noticed a power drop but an engine loudness increase. I was always under the impression that the engine got louder because there was more air running in it.

I'd recommend the following mod instead for your air intake. All it costs is time. I've done this mod on countless cars over the past 20 years - everything from a 4th gen f-body to a BMW 740 and I've always been happy with the results.

All cars have to meet very stringent noise emissions levels these days. The automakers try very hard to quiet down the intakes so that they can meet these low levels. But the auto enthusiast loves to hear that intake "roar"...so what to do ? Spend $300 on a shiny pipe with a conical K&N which may or may not filter air as well as a paper filter (And may coat your MAF with oil) ? Or...

Take a power drill with a 3/8" bit and drill 30-50 holes in the "dirty" side of the airbox. This lets more air in, and the great sound out. I'll be swiss-cheesing the M35's box as soon as I can find some time.



I checked out the factory setup last night. It's very well designed and you're not likely to better it easily. The airbox is very large and there are two paths for air to get into the box, each pulling air from right behind the grille and over the radiator.

Let's see what some holes will do....

On the Maxima, there is a "GAB" mod (short for Ghetto Air Box). The Maxima factory intake has a section on the top that is removed to replace the filter, in some cases a coathanger has been used to wedge the filter in thus allowing that section to stay open ( http://www.nicoclub.com/articles.php?id=157750 ) while some have simply cut it out and added additional 3" holes on the bottom side as well. In dyno testing, these mods have resulted in the best results out of all the aftermarket intakes.

[NewfoundlandDude]

audtatious,

Do you have any more info on the GAB?The attached article was awesome, but I'd like to see a write-up on the tests, ar really anything else on it if you know where to find it.

Thanks.

[shaitan]

Hi everyone,I don't really know much about all those performance figures you got there .Correct me if I'm wrong, I think you could have gotten better results with your CAI if the car was actually moving and colder air was getting in your intake. BTW, how does the outside temperature affect the performance? If you will find any grammar or spelling mistakes then excuse me, english is not my first language.

P.S. I was thinking of getting the same intake for my M but now Tony just f***ed it up for me lol

Try the Maxima forum for additional information as I have personally never tried it.

CAI is supposed to allow the engine to pull colder outside air instead of the warm air under the hood. There is really no "ram-air" hp increases as you will never have the vehicle going faster than the engine itself is pulling the air into the intake.

Cooler outside temps do = better performance regardless of stock or modified.

Not sure what you've read, but the tests I did were all road tests (when the car was moving.) Every 10 degrees F difference in temperature, there is about a 1% loss or gain in HP (see one of my previous posts in this thread.)

Regardless of the losses I experienced, I love the way my intake sounds. Plus, there may be a benefit in decreased intake air temperature in hot weather, especially in stop and go driving. I definitely have noticed a difference and the car seems more responsive after sitting at a red light, in rush hour, etc. than before the intake was installed. Not very scientific, but those are my observations. This is why I've chosen to keep it on my car even though I experienced a overall loss under controlled conditions.

Check the date on my post there, I think it was my first day months ago.I guess that I did a search for GAB or something.Other than that, I have no idea why I'd post in the M35/M45 Section??

Who knows

As long as you are here it don't matter

Oh, my bad, thought you said it was dyno (it' when the car doesn't move, right?). Where I'm from, it's really hot most of the time and it doesn't usually rain but when it rains the water goes up to the stomach of the car. And, I'm scared that the water can get into the engine. So, what do you think should I get one for myself or no

Correct, a dyno is when the car is usually strapped down and HP and torque is measured by the tires rotating a large roller against resistance.

The filter definitely goes down pretty far towards the ground. There is a plastic shroud that seems to keep all "normal" rain away from the filter. It should be noted that you wouldn't have a problem unless the intake is actually submerged in water and it sucks it up like a vacuum cleaner. If the rain you get is that bad, even if it's rare, I wouldn't take that chance. On the other hand, there is a cover you can put over the filter that keeps water out. I can't remember the brand name, anyone? If it were me though, I wouldn't take the VERY expensive chance of ruining an engine with water that high.

Most OEM CAI intakes are placed in a high pressure area and the VH series had built in resonators to improve flat spots in the torque curve. Hundreds of hours of experimentation and comuter modeling. Few aftermarket manufacturers can afford this because ultimately the sell even far fewer units.

What do you mean by "high pressure area?"

Tony

[buckeyechiro]

I am curious as to what a VH series is as well as what "High pressure area is"?I am looking at installing the Injen CAI real soon. Then I will be just like TONY, with the E114 Cat back exhaust and CAI. I'm with him, it's the sound and fun of modifying that makes all this worth the investment! I'd love to line em' up! This car is awesome, no bones about it! For those of you who are happy with the stock m45, with all respect, we're happy for ya....

Patrick Cooper

[Spoolin4days]

V stands for VH45 (the M45s engine code). I believe the high pressure area is located around the radiator. This is where air goes that does not pass through the radiator, rather around it. It has a sort or "ram" effect into the intake ducts.

First of All...Most Awesome Thread Right Here!

I also dynoed my car on a superflow and got 225whp + or - 1 whp. it is also a greedy dyno! Dynojets give me 30-50+ superflo readings. I am all stock other than drilled and slotted rotors + a K&N filter. The filter gave me 1 or 2 whp. Not sure if they weight more or less than OEM, but our number are consistent! That is the good part!

I think your CIA should work better in theory though the problem is probably that the cool air is not directed-forced into the air filter like the OEM box. I am readying my car for a custom airbox mod and I will keep you updated. After that is is exhaust then aluminum pulleys.

Updates to follow. And more news from you Tony?Thanks, Kyle

Afraid not. I sold the M last month. The guy I sold her to loved the intake and exhaust though.

That sucks man! You have a newer one?

[CocDiezel]

Funny , I bought this M from Tony and I LOVE it! Tony is a great guy : )

Crazy, but I stumbled onto this post. Tony really took good care of this ride and the exhaust and intake sound sweet! Probably the best sounding car I have ever owned.

I love the engine in this thing, but Im always looking for more power/speed. Is there any other bolt on mods that can be done for more horsepower gains?

[M4T5]

There are a few things on the horizon, but nothing much since Toni did that testing. UpRev should be able to tune the M's by now. I guess I'm not understanding why the intake kit is on your car since Toni's test results concluded a loss in power with the addition of the intake kit.Didn't you get the same thoughts out of the beginning of this thread's info listed from Toni?Did I read something wrong?

[CocDiezel]

I just love the way it sounds with both. The slight degrade isnt too big of a deal to me.

But I did see his conclusion had smidge better perfromance with the stock intake.

What is UpRev?

UpRev is the ECU tuning company that tunes nissan only ECU's. They have my ROM file from my stock computer and they are trying to crack it so they can make it tunable. Funny that I read this now as I just got off the phone with Richard from UpRev and he said they are still working on it. He said the problem was - and it wasn't really a problem - that these cars, engines, ecu's are manufactured in Japan so the engine programming is nothing like they've ever seen from here in the states. He said it wasn't a problem, but more or less they are testing it so that there are no problems when it comes out here.
