Mazda 3 GT With Fujita CAI

Ok, got my intake installed today... and also decided to get my car on a dyno!
I don't have my digital camera right now, but as soon as i get it back I will show the dyno results but for now i'll just tell u the results.

first run (no cai)
Max HP = 123.46
Max Torque = 130.76

Second run (with Fujita Cold Air Intake)
Max HP = 134.38!
Max Torque = 139.75!

Final Results 10.92 HP Gain!! and 8.99 Torque Gain!!

Sorry about the double post, didn't know which forum to put it into.

I took a video of my car on the dyno (with my camera phone so it's pretty crappy, but u can still here the intake especially in 4th gear)

A 10 hp gain is really good. I'm considering getting a CAI but I don't know what to get yet. I was considering going the cheap way and buy a e-bay intake and slap on a AEM filter or something.

10 hp gain to the wheels is AMAZING !!!! and just from a CAI !?!?!? I would like to see the dyno graph to see the powerband

As soon as I get my camera back, I will take a pic of the graph and post it...
I tried using my cell phone for the pic, but it's useless.

That's the best i can do for now

those are pretty solid #s and the power band doesn't look really any different than the stock...so i guess that's pretty good

Good for you. That's quite good for just an CAI, and at the wheel too.

Good numbers!! How much was it and how many runs they give you for that price?

$100 for 5 runs

wow thats stock.............almost 17hp off

That is quite impressive, especially for a bolt on. I wonder if the MS intake returns similar numbers. 100$ for 5 runs? I might just do that one day when the car's all done.

Actually more. He's got a GT 2.3 which is supposedly 156hp, so at the wheels 123 is quite the difference. Loses, gotta love em.

Zubby are you running with an AT or MT?

MT, i was pissed off with the stock run 123 hp... I thought it would be a little more than that!

Dammmmmmmmmm

It just kinda flowed Zubby!

The loses are quite intense, I'm surprised to. The automatic probably puts down about 5-8lb/ft less because of the slushbox losses.

Every mild tuner goal (one I've set for myself), is to attain the wheel horsepower that was advertised at the crank. So I eventually want 156whp. This can be attained by intakes, exhaust, headers and pulleys. From there on your really tuning.

wow, those are impressive increases!

Yea I was happy with the intake and it's performance, but I still thought a stock GT 5 Speed would pull off at least 130 HP.
The guys that were setting up the dyno were making guesses, and I heard one guy say 108.

dynos are not always the best for a true measurement of HP...every dyno is calibrated to read differently and a lot of other factors come into play also such as air flow/temperature/pressure level.

dynos are primarily used as a measuring device of how much power gained after a modification...so you can see the amount of increase, but the actual figure maybe off.

thats hard to believe, i can't feel anything with mine. but the dyno doesn't lie i suppose.

I doubt you'd feel 10hp. None of us are that in touch.

wow, wonder if other intakes have the same effect or not

The difference between a GX/GS and a GT is 10 hp. And I can feel each and every one.

agreed :bana

Well. There is more to that than just 10hp. There is 16 crank horsepower which is more like 10 - 15 wheel horsepower. Plus the torque is less. There is the ambient feel of being in a less sporty model. The 2.3 is a much stronger engine than just its numbers suggest.

I guess you could feel the difference in horsepower though. The question is, on your 2.3L did you feel your intake make a differance?

Ok, I did maybe a little in the mid rpm range but not really. Mostly I noticed the wonderful sound.

EDIT: Fixed some of the above numbers, I was obviously on drugs that day :S

huh?

the crank is more than WHP.. :complain

i'm sure he got it backwards....

Were you not just reading the thread guys? Our car has 156hp (At the crank).

The dyno results on the previous page show 123 wheel horsepower. I'm not backwards. Its drivetrain losses.

Although your car may put out tons of torque in first gear, its not a measure of its true power. But on that note, I don't know the details of how a dyno calculates the exact power at the wheels.

man i am so confused with what you're typing..

the 10HP gain is at the wheels!

thebiz and sean80 are talking about the [advertised] ~10HP difference (crank) between the gx/gs and gt models..

if we compare the stock numbers to what zubby got we get
156HP/150TQ (crank/advertised) vs. 123HP/131TQ (wheels) which translates into 21% and 13% losses respectively

if we use the same losses (gross generalization), 148HP/135TQ (crank) would be 117HP/117TQ (wheels) for the 2.0L engines..

and if you want to translate his WHP gains to what the advertised ones would be then.. 134HP/140TQ (wheels) would be 170HP/161TQ (advertised)

man i just can't believe that we lost so much from crank...also, i thought the M3 2.3L put out 163 not 156...or did the HP rating changed over the years?

I really want to put my car on dyno as i want to see how the 5 speed auto with my mods will do.

I remember lawrence did a dyno on his 4 speed auto stock to the bone 3 put out 129whp IIRC.

That's seems kinda high for a stock automatic 3. Makes me think even more that my stock manual 3 shoulda put out more than 123whp.

Yea, Maj, thats exactly what I was saying, I didn't know that the GS/GX had 148, I thought it has less. Also, I did mix up my numbers before.

But like I was saying, its not just the 5hp differnace you notice in the 2.0L because its such a minute amount.

thanks for the clarification majic!

all i can say is when i test drove the 2.0 and then the 2.3.....i made sure it was a 2.3 that i got. It just felt much stronger than the 2.0.

and on a side note: i test drove a cobalt ss right before going to mazda, and I swear the 2.3 mazda is a faster car

3rd one down you'll see xenon with 127WHP stock to the bone.

Mine's a 06 and it's rated at 160Hp, the 07's are 156Hp. I think it's something to do with the SAE, but really it's the same engine.

I think Xenon's dyno is more accurate since he lost about 20% of the rated Hp which is around the amount autos are suppose to lose. So I think a manual should be around 136Hp.

I would split on a dyno day if it was in the mississauga area...

I want to wait until i put the Motul 300V oil in there.

This is just another case to prove that hatch's are better than sedan's :)

^^ Especially white. =P

I'm not a hater. But there is no F'N way a CAI gave you 10HP.

So I guess in winter your car pulls 200hp???

Sabs its right on the dyno sheet!
