Attn: Phenolic Intake Manifold Thermal Insulators

[mp3rican007]

Hey I love the internet just to start off you can find anything and everything. Well guys and girls, I found another performance modification for our 2.0 FS Engines that not only gives us power, gives us better engine reliability, gives us better 1/4 mile times, the best part it only costs 100 bucks. Found this guys site called OUTLAW ENGINEERING, now this guy has a pretty impressive site being his own go there and read you will see what I mean. He did every test to get his results.

He said this will allow you to run turbo, nos, supercharger with increased reliability, now somebody RATE ME and give me some stars

 

[PaulMP3]

u gonna buy these. how do u install them?

 

[derrick1623]

no more stars

dude, the rating system is no more.

The whole idea behind the phenolic spacers is that they seperate the intake manifold from the heads of the engine, thereby keeping heat transfer from teh heads to the manifold down. this allows the air entering the manifold to stay cooler longer. They don't really add any power, they just keep you from losing it to heat longer. I've had a set of the original ones on my MX-6 for a couple years now and can definitely say they work adn work well. After install a fellow car club member who has a Probe and I went to the drag strip for a few test runs. After 4 runs that were pretty much back to back we could still put a hand on my intake manifold whereas his was too hot to touch even for a second. Also I was having better runs than him and usually he would beat me.
Sean also makes throttle body spacers, but I don't know if they are up on his site yet. If you have a coolant line running in to the throttle body it really helps keep the heatr out of the intake manifold.
These are a definite buy for any car in my book.

im ordering these today.. hopefully ill have them by sat so i can use them in the auto X im going to.....
i can tell that on our cars we have a lot of heat soak... so im going to do this to keep the reliability and be more efficient.. and maybe ill gain a little bit of power.... its a good deal for $100.. i may go get dynoed after i get the spacers and cams in... so i will have spacers, intake and exh cam, aem intake, and modified exhaust....

maybe i can get into the high 15's or low 16's

I mentioned this site about 6 months ago and nobody responded so I thought it was crap. But I am open to a second opinion.

Very interesting. I also like the way the theory was explained in detail and results were posted to support it. (Hopefully it's not bogus)
Let me know how easy the install is maz_18. BTW, you sun STS? I don't think I can do that in stock, but maybe I'll go STS next year. They need a good shooping from a little 4-door Mazda to cool them down. (Damned subarus)

 

[mazdamp3_18]

yeah im gonna end up running sts.... hopefully i can push the limits of this car.. sometimes its scary at the limits... lol... but as soon as i get my mazdaspeed coilovers im gonna start kicking some major @$$.... i wanna try and get 1 g or more out of this car on the skid- pad...

im gonna probably need larger swaybars though... i saw in scc a integra had 27 mm rear sway bars....

I thought that if you bypass the engine coolant it would maintain the throttle body cooler longer. The Engine coolant going into the throttle body will eventually heat up the throttle body therefore heating up the air coming through.

I thought buying these and buypassing the engine coolant from going into the throttle body was the way to go....

 

[cjstringer]

Have you autocrossed yet? Not sure what the deal where you live is, but this car is moppin up the competition around here. She handles like a dream and I'm all stock. I'm not gonna play with the sway bars, just tire pressures. I can pretty much get the car to do whatever I want it to now by playing with the tires.
Make sure you get that right before playing with the other stuff, or you'll be forever trying to fix too many things at once.
This piece does have my interest though. I wonder how visible it is sitting under our engine cover?

 

[mazdamp3_18]

this will be the first autocross for the MP3, but ive autocrossed twice before in my 2001 Golf TDI... i had a blast, i havent raced the mp3 yet since Michigan SUCKS b/c we have snow 5 months out of the year....lol..... what pressures have you found optimal for yours??? im thinking of running 42 front and 38 rear... what do you think you have more experience than i do.....

 

[cjstringer]

I put weather conditions, track conditions, tire pressures, and whatever else in my autocross result link in my sig. Pretty much ~41 front and ~35 read seems to work the best. Might want to start with ~36 rear though. The 1 pound difference in the rear is HUGE for how the back handles. (Understeer vs oversteer) It's better to start out pushing and adjust in 1/2 pound increments in the back (down) to get to more of an over steer state.
Just my observations.

 

[chdesign]

Just think what Auto-x class i'm in I roll up there entering in Steet Mod class lol

 

[SilverProtege5]

I have the TB spacer and the phenolics on my Probe GT and i think they did help, If nothing else it will help you MPG buy keeping temps down.

 

[deepcover6]

Hey mazdamp3_18 did you install the phenolic intake manifold yet?

Just wanted to know how easy it was to install, and did you personally notice a temp difference once installed. It's getting hot here in DC, need to keep engine intake manifold temp down. I know over a period of time this heat does effect or will start melting away the Injen elbow attached to the intake manifold due to the heat. This contraption would be really handy, if it works as mentioned.

 

[SilverProtege5]

There is a noticeable temp difference but in the Mazda V-6 there is a coolant line running through the TB so it kindof defeats the purpose, the I-4 on the other hand doesn't have that coolant line i don't think.

 

[deepcover6]

So you have it installed in your P5 SilverProtege5?? I want to know how long it takes really, and if it is easy to do in ones garage without chance of messing things up. Thanks.

 

[SilverProtege5]

I haven't done it on the P5 yet, but the V-6 is 10 times worse to work on, you can do it with basic hand tools, as long as you can remember where all the hoses go.

 

[chdesign]

Our FS motor does have coolant lines going to the throttle body by pass them and you will cool the air down some I'm going to order the spacers soon as I know they help I had them on a Triumph spitfire adn it did wonders for it. But I'm also doing alot more than just that to my motor lol.
