intake manifold

[ProtegeGuy]

i was searching thru protegegarage.com and saw the intake manifold on there. it says for a mazspeed but doesnt say for an N/A. will it work for an N/A? is it worth 200 $'s?

 

[Tom03es]

It will work, but Ken from Protegegarage does not recommend it for NA engines.

Just remove your VTCS and port and polish the manifold.

Will not work you will loose low end torque.

Will not work you will loose low end torque.

how does that equate to "will not work"?

You'll gain power overall.

 

[ogsp5]

Let me change that statment. Yes it will fit but with a N/A set up your bottom end torque will be lost. When my car was n/a that was the joy of driving my P5. This unit is best from what I read for F/I application.

but you'll still gain power overall.

Not everyone subscribes to the "low end torque" importance....it depends on application. For a fun get around, yeah its useful - but for race applications, a loss of a handful of horsepower down low to gain a whole bunch through the midrange and top end is a worthwhile compromise.

Lordworm is right. Most of your races are won with HP in the upper ranges.

Most people race from "rolls" anyways so low end HP and TQ are prety much useless. Just look at Pro Stock in NHRA. They win most of there races by pulling up top. Now I know NHRA and our cars are two completly different but the fact remains it's better to make power up high

Worm: How hard was it to retro-fit the intake on your car?

 

[jamesk]

do you think i should buy one since i got a fidanza flywheel and udp? maybe i wouldnt loose that much low end

 

[Turbo 331]

You WILL lose low-end because the loss of velocity but you move your power curve up high

 

[LordWorm]

honestly, who CARES about low end? bottom end power represents the power available to you when cruising. If you want some get up and go, back it down a gear and floor it.

I havn't retrofitted an intake on my car yet

i'm designing (very complex engineering ...) a custom tubular manifold at the moment...

Shouldn't be hard, just bolt it on

pipe work for the intake tract will be the more difficult job i think.

 

[jamesk]

dont you throw a check engine light though? i thought you had to have the vtcs and vics pluged so the car thinks its working?

NA civics get big bored out intake manifold for their cars and it does work for them. but thats a different story, their cars have vtech that rev much higher, so the car doesnt have low end anyway.

do you think were gonna need bigger injectors for this manifold? my car runs a ratio of 10.0:1 right now. its really rich, but if i get this manifold it will probably be normal, so thats what im hopping.

i might buy this manifold just to try it out. if it sucks ill just sell it. but i just dont want a check engine light because of vics and vtcs. i have the mp3 ecu so vtcs doesnt matter, but if vics is not plugged in, do you get a check engine light?

 

[Dermen]

Keep the VICS solenoid plugged in and you won't throw a cell.

 

[jamesk]

o true. alright ill let everyone know if i order the intake manifold. so no one else has this manifold for NA?

what do you think lordworm? is this a good risk to take?

 

[Turbo 331]

Someone said that you will only gain 5 peak HP on a NA car. I caqn promise you if you look at a dyno graph of a Protege that this manifold you will see more HP elsewhere in the curve.

"PEAK" Doesn't mean much to me. You will gain more than 5 HP under the curve so don't think by just bolting this on you will only get 5HP. You just might get a "Total" of 10whp

 

[jamesk]

what do you mean? do you mean im only gonna gain 5 peak hp, or 5 hp gain throughout the whole rpm range?

was your comment postive or negative towards buying the intake manifold?

 

[niky]

Positive, I guess. What he means is that 5 peak hp isn't indicative of midrange gains you could get.

With the limits of our heads and cams, gains at peak aren't going to be very dramatic for breathing mods, but if they're good mods, they'll net you a lot more gains in the midrange.

 

[Turbo 331]

I didn't mean anything negative at all. If you go back and re read what I said I said that people on here are saying it will give you only 5hp tops. I'm saying you will get more than that under the curve.

Look at it like this. It will keep pulling like it has enough power to go all the way to top speed limit in your car. Me personally I would much rather have that and give up hp and tq down low to have more up top

Thats it...
upper midrange to top end power for the win.

Torque is for pulling caravans.

Couldn't have said it better myself and if you were to throw in some good cams like "Twiggy" or maybe even the Integral cams it will pull really hard to redline
