mattlau89 Posted March 5, 2008 Report Share Posted March 5, 2008 sorry if its kinda blurry my scanner broke on me. but yea check out my slow car i got the scuff plates if u guys want to see them Quote Link to comment Share on other sites More sharing options...
street3890 Posted March 5, 2008 Report Share Posted March 5, 2008 How much power? And is it an S? Quote Link to comment Share on other sites More sharing options...

Renboy Posted March 5, 2008 Report Share Posted March 5, 2008 There's something seriously wrong with that heart-break dyno you went to. There's no way you have a 40% drop in driveline power. That dyno undershot your engine by about 40hp. And to prove it, I'd like to see anyone with 97whp pull a 3500lbs car across a 1/4mile in a little over 15 sec.

///BHRpowered Posted March 5, 2008 Report Share Posted March 5, 2008 meh, I still don't really like the look o the scuff plates, look alittle better with gray interior though. Quote Link to comment Share on other sites More sharing options...

mattlau89 Posted March 5, 2008 Author Report Share Posted March 5, 2008 in a dyno u have to add around 2 seconds to the quarter mile because there is no wind resistance and other variables. Quote Link to comment Share on other sites More sharing options...
enginph Posted March 5, 2008 Report Share Posted March 5, 2008 in a dyno u have to add around 2 seconds to the quarter mile because there is no wind resistance and other variables. You really believe you have 95hp on the wheels? Quote Link to comment Share on other sites More sharing options...

enginph Posted March 6, 2008 Report Share Posted March 6, 2008 WTF is wrong with 2.5L dyno results? This is from the pissbucket: Same dyno same day, 2000 S 142K Fouled Cats (ALL) Leaky valve cover gaskets Leaky oil sensor O ring 19's All stock 176 whp max 191 lb-ft torque max 2002 2.5 76K Jet ECU Reflash Cold Air Intake 19's 122 whp max 125 lb-ft torque max Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 6, 2008 Report Share Posted March 6, 2008 This is from .org: key word: pissbucket btw...that isnt ur trap sheet. unless u have 4 cylinders. Quote Link to comment Share on other sites More sharing options...

mattlau89 Posted March 7, 2008 Author Report Share Posted March 7, 2008 we dynoed a corolla s right before my car so we left the info as it was. my cai made me lose hp because i dont have the exhaust. too much back pressure. Quote Link to comment Share on other sites More sharing options...
Frankzao Posted March 8, 2008 Report Share Posted March 8, 2008 Back pressure? What does that translate to? What happens when it gets too great? Stalling? or Hesitation? Quote Link to comment Share on other sites More sharing options...
MazdaMomma Posted March 8, 2008 Report Share Posted March 8, 2008 I think that too much back pressure causes hesitation. I could be wrong tho. Quote Link to comment Share on other sites More sharing options...
enginph Posted March 8, 2008 Report Share Posted March 8, 2008 I still couldnt get the point of a custom CAI. Original equipment gets cold air and it is intake so it is a cold air intake Whats the point of changing the routing. Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted March 8, 2008 Report Share Posted March 8, 2008 Less pressure loss and lower temperature both translate to more power and better gas mileage. Temperature is just the temp of the intake air, but pressure is determined by the length of the pipe and the amount of restriction. By having a shorter intake with little restriction that takes in colder air you will improve power and efficiency. The same is true for the exhaust. Backpressure results from a more restrictive pipe. An exhaust with less backpressure increases power.. and noise. My intake takes care of pressure and temperature. Quote Link to comment Share on other sites More sharing options...
MazdaMomma Posted March 9, 2008 Report Share Posted March 9, 2008 how so? Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted March 9, 2008 Report Share Posted March 9, 2008 how so? I posted a topic about it a few days ago with pictures, but the filter is right in the engine bay so the piping is only about 5 or 6 inches long including the MAF, so there is minimal pressure loss, and there are ducts that are located under the car that send air directly to the filter whenever the car is in motion. The air gets sucked in when accelerating and cools the filter when coasting. I have tested it in many different conditions so far, the filter and pipe are ice cold even after driving for a while. I have driven in the rain a few times and not a drop of water has made it up to the filter. Quote Link to comment Share on other sites More sharing options...

But intake air is slow and loss is proportional to flow speed. Someone with MAP data before/after CAI? (hard request) Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted March 9, 2008 Report Share Posted March 9, 2008 the CAI won't cause you to lose HP, you just might not gain any at high rpms. the dyno looks very wrong, I think they gave you the chinks sheet. Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted March 9, 2008 Report Share Posted March 9, 2008 http://www.mazdaworld.net/forums/index.php?showtopic=2602 The temperature of the filter and intake piping itself is always very close to ambient temperature becuase it is being cooled by the air that does not enter the piping, and the air (when the car is moving) is at ambient temperature, so there is an improvement in temperature. The short piping allows a very small drop in pressure compared to the stock box. I wish I had some real data to post. I can say that I notice an improvement in throttle response, gas mileage, and acceleration feels stronger, but keep in mind I cleaned the MAF at the same time and a few days before that I replaced the vacuum lines, so that could account for some of the difference.

Hard to say it gets enough air there. I mean on a 90F day with stop and go traffic this will be a real HAI. It will be cold on highway, no doubt..

Matt64341 Posted March 9, 2008 Report Share Posted March 9, 2008 If you go for a drive and its 30 F out and feel the stock intake box, its not going to be very cold because it will be heatsoaked by the engine. When I feel mine after the same drive it is as cold as the outside air, so even on a hot day, it will be warm as warm as the outside air, but still cooler air than the stock intake would be able to take in.
