installed single runner intake manifold on my mp5!

[TheMAN]

Any plans for any actual dynos or are we going to have to rely on your butt dyno?

Do you have any pre-manifold dynos by chance?

yeah, never trust the butt dyno
you feel torque, NOT power

I have a hard time believing this s*** works better, otherwise, why did mazda designed and built an expensive intake manifold for the protege when they could save big bucks by just putting this cheaper one one?

It's just one of those mysteries of the universe that we will never figure out.

Gas mileage? Oh wait, that kind of sucks too... Well I understand the improvement for the turbo Proteges but not necessarily for the N/A guys. I remember when I removed my VTCS back when I was still N/A and I thought I felt a big difference. Now however I can't even tell differences with upgraded turbos, lighter flywheels, etc. I'm guessing it was just a placebo at the time. Now I'm not saying the 626 isn't giving any gains but I'd say give it some time. The Protege ECU is notorious for learning around mods after time...

Probably for the aftermarket sector. Car companies do that s*** all the time. ie: our factory exhaust manifold.

Huh? Are you saying that Mazda purposely designed a crappy intake manifold just to give the aftermarket something to improve upon?

Who said that it was exspensive to make. and hell they put in cheap rods why not an IM to....?

This is an explanation by LordWorm(NA Mod)about the IM.

BASICALLY the VICS is a half assed attempt at a duel runner intake manifold...and more or less provides variable intake runner geometry meaning it can be tuned for both bottom end and top end...it doesn't do this whole thing very well, but it does work to a degree

a single runner manifold is "tuned" to a specific rev range, i've posted the formula's for working this out else where.....and the 626 manifold appears to be tuned for upper mid range/top end, sacrificing bottom end in the process.

So a sacrifice of power from 1k to 2k rpms isnt all that bad. In "spirited" driving you'll never see anything lower than 3k rpms anyway. But I would like to actually see what and where the gains are for this, in the NA application

 

[jamesk]

well everyone is forgetting this, this intake manifold is a free flowing intake manifold, no restritictions at all. if my protege was stock then i slapped in the intake manifold, the gains would be minimal and i would loose power in the low end. you need the supporting mods to do this upgrade or its useless.

so mazda can not put this manifold into our cars from factory because our cars stock would run like s*** with it, the cars stock do not make enough power for this to be affective.plain and simple

i just installed a thermal spacer for a intake manifold on my friends civic si. i was curious to see his intake manifold design, and it is very similar to the 626 manifold. they both have the chamber at the bottom then goes into single runners with no restrictions. the civic si is able to use this manifold cause of the high hosepower, thats why people say turbo cars are better with the 626 manifold.

this intake manifold is a guarenteed fact that it would give us a gain since there are no restrictions. the stock manifold is way to restrictive and causes too much turbulance anyway, so the risk i took was, if our cars would benifit from some sort of a design because of our lack of power? i feel, with the supporting mods, YES, our cars will benifit.

after i get my afc ratio's tune, that should give me a high gain since there is so much room for improvement. maybe later on the ill throw in the j-spec intake cam since the duration is bigger, and that would work very well with the manifold.

plus mazda wanted to keep emission status as well.


if anybody wants to buy one and has any questions in throwing this manifold into their cars, lmk.

Well the thing is they do have these on the FSDE stock. The mazda 626 that the FSDE 2.0 is in.
Its the same motor. and the same years I believe to. but for some reason they only put it in the 626 equipped with the 2.0

Of course. Why do you think the after market industry exsists. Car companies make a product that is satisfactory as far as the economy goes. The after market companies make products to imorve on performance and looks. Ya know what I'm sayin.

I'll agree with you to a certain point however I don't think Mazda ever intended to have things like aftermarket intake manifolds available. Sure, Mazda has been offering "Mazdaspeed" products for some time now such as springs, struts, coilovers, swaybars, etc. but only IIRC only recently have they jumped into aftermarket engine performance parts like air intakes, etc. Mazda tuners like AutoEXE take care of the rest but even then it's still mostly parts like exhaust manifolds and sparkplug wires.

I agree, however there will always be people out there who will experiment. There are guys on forums who design parts like manifolds. The get a ginniepig and a dyno and see how their product works.

People like that will always be around. I'm not gonna complain about it. It just means that I don't have to do it.

Whereas yes, there are always going to be companies and individuals making aftermarket parts for cars I highly doubt Mazda specifically designed certain parts to be "upgraded". With the Protege, I honestly doubt they even expected it, at least not until the MSP (or MPSs in Japan). Had they expected it I'm pretty sure they would have put more effort in the engine like everyone here is saying they should have.

You are right. They did it to get the most out of their car and get fuel economy at the same time, leaving a wide open path for the aftermarket community. The reason I said that is because you always see cars that you can improve upon. If car companies were smart they would offer cars with differant performance options...ie: suspension, intake, turbo charging, ect.

The last time that happened was the 60's when you had a choice of motor when ordering a car... ie: the Chrysler Hemi or and company big block vs. small block. It would be nice to have choice right. Although there are companies like Subaru who offer the Impreza and othe versions of it such as the popular WRX and the more powerful and better handeling STI. Imagine how happy we, as Protege owners would be if we could have ordered the FS-ZE in our cars instead of the FS-DE. 40 more horses and more torque. The car is already fun to drive, just imagine. Then imagine turbo charging the FS-ZE instead of the DE. SO SWEET IT WOULD BE. It would be nice to have that option, right?

Some companies still do that. I mean, Mazda still usually offers a wide range of suspension upgrades for their vehicles but look at Chrysler (Dodge) and Mopar. I mean they at least had 3 stages of upgrades for the Neon SRT4! I agree, it really would be nice if most companies did this.

 

[dwpeek]

Could you imagine spending less mone for more HP with the ZE instead if the DE... AH it would be sooooo freakin nice. Oh well, we can dream.

exactly.... the 2000-2002 626 had the EXACT same motor as the protege except for the intake manifold
so what power did it get? 125hp @ 5500rpm, and 127lbs/ft of torque at 3000rpm

way to go, the engine now makes less power and less torque and the powerband has shifted to a lower rpm!
mazda did this because it was cheaper to produce for the more expensive 626, and there's more low end torque to move the heavier car around as well as providing better low end response that the typical mid-size car buyer wants... they kept the more expensive VICS system for the protege as it is the sporty car

 

[MakeMeGoFast]

Why all the hostility, what because he's trying something. What because he is going against what people "think" wont work, no one has proven this either way to my knowledge. With his mods this should actually be beneficial.

And do you think that the ECU could be different on the 626 since its not a "sporty model". Did you ignore my other post with the quote from LordWorm.

 

[TheMAN]

I think its obvious the ECU is different

 

[magnumP5]

Either way, the gain is there for the turbo cars so that's all I care about!

 

[djarkitek]

I've only been argueing this for about 1 year now...but noone listens...ask anyone who has seen my car pull if they think the 626 mani from Protege Garage works, CAUSE IT DOES.
