GET EM SLUGGER posted:I've heard two different stories about intakes. One story is that they make a huge difference in power. The other is that they don't do poo poo but make the car sound better. So is it really worth spending $185 on a new intake? My car came with a K&N filter from the previous owner, if that means anything. The stock air box is one of the great crimes against automotive humanity. If you take a good look at it you'll notice that the inlet bottlenecks down to something like a 1.5" diameter opening. It's just asinine. Hagetaka posted:That seems like kind of a weak excuse, would they really have to do that much drat re-working to move a fuel pump? Is location that much more critical on DI engines or something? It's a mechanical pump driven off the cam, sorta like a diesel. Makes sense considering the challenges of fuel injection into a pressurized combustion chamber. It has to supply really pressure along with the volume. Anyway, has anyone replaced the stock recirc valve? I hear they tend to leak boost. I'm not terribly concerned about the sound, but I hate to think that valuable power is just being wasted. If anyone has gotten sick of their motor mount, sell it to me.

Are there any throttle response upgrades for the normal non-Speed Mazda3? I really hate the delay programmed into the electronic throttle when I clutch in.

Yeah, I went out and took a good look and the intake is pretty horrendous. I guess an SRI is gonna be my next mod.

I didn't figure it was worth a drat, but I thought I'd throw it out there. I understand the difference a good intake can make, and I know Mazda makes theirs horribly restrictive. I had just heard the two different sides and wondered if any of you had any experience with intakes on these cars. I've pretty much decided that I'll get one next.

So is there anything at all I can do to make my Mazda 5 faster? Because you know I have to get the kids to soccer practice faster. It's got an MZR engine, anyone have a comprehensive list of the differences between it and the DISI turbo motors? Other than the DISI and turbo, obviously?

I really like my Cobb intake. I can't say that I felt any added power with my rear end, but you can just tell you're doing a good thing when you see the diabolical contraption you pull out to make room.trouser chili posted:So is there anything at all I can do to make my Mazda 5 faster?

Well, I ordered my Accessport from Grip Garage yesterday. Thanks again for the heads up on that Frosty-. I got it in just before the price went back up. Now if it would only get here tomorrow like he said. I want it before I leave town for new years! BTW, Kevin at Grip Garage was a super friendly, helpful guy. I had problems paying with my debit card, and he was very patient with me. So seriously, thanks for the heads up. Someone else might not have been as friendly.

Tripped across this on mazdas247.com. Some of you suffering from a fuel-cut at high RPMs on cold mornings may benefit. I know I've been seeing it on occasional on-ramp WOT trips. I may try it. If I do, I'll post pictures and a writeup.

As alluded to in that post, Cobb has maps with the cold weather fix included for those with an AP.

^^What he said. cp-e has nuked the fuel cut algorithm entirely and Cobb has shoved the triggers way back in their OTS maps.

OK, so Cobb says to go one step colder on the spark plugs. I'm going to have to order the Densos. If I shorten the gap on the stock plugs and run the Stage 1 map for a bit, is it going to blow my engine up? I can't get the Densos anywhere locally, and I'd like to try out the AP this week.

joey deere posted:If the stock intake piping is quite restrictive it can make a reasonable difference. The difference between a K&N and a regular paper filter is practically nothing though. BITOG did a pressure drop test and found a 0.14% air flow improvement with a K&N over the worst paper filter. BITOG may know about oil, but I value real world testing over lab stuff. I know I, as well as a few thousand other people, picked up 2mph and 2 tenths in the quarter as well as gaining 2mpg with a K&N in my Mustang GT.

FlyingPotato posted:How is the Accessport to use? Is it similar to a full blown laptop EMS system, or is it more like an OBD2 scanner that requires you to push the same button 50 times to do anything? The AP is an on-the-fly map changer with some added bits of flair and style. It can read codes easily enough, give you a ton of engine statistics, and change maps, but no actual tuning can be done with it. It only just flashes maps. The COBB proTuner software is the only way to tune a COBB acessPort map, and proTuners are hard to find because COBB only allows one or two licenses per major market for no good reason. If you're going to get tuned and don't need to switch maps often, go opensource.

I ordered some Delco Iridium plugs in the correct heat range from the local O'Reilly. They're half the price of the densos, so if they suck I won't feel lovely about throwing them away. Well, LESS lovely.

GoblinBomb posted:I see a lot of people saying that K&N filters are terrible, but what do those people consider the best filter? It's academic, because whether or not you're a dedicated modder you MUST yard out that abomination and replace it with a cone-filtered SRI or CAI. To leave the stock airbox in place is a big mistake IMO, since the stock setup is a huge performance and mileage killer. I gained 3 MPG doing my backyard DIY SRI.

Has no one considered the cp-e StandBack? Just curious as to why those with the accessports chose Cobb over the cp-e Standback. Its an eternal debate over at various Mazda boards on the web so I am wondering what the general idea is on these forums. (I own a Mazda3)

I'm curious about the details of how you made the SRI, if you don't mind sharing. Air straighteners are not required on an SRI - because once the air gets sucked in through the filter and by the time it travels the very short distance to the MAF sensor - there is no need for controlling the air flow. Most important thing is the MAF housing - that needs to be a precise diameter - thats what the MAF sensor was set up for - changing the size of that, changes the tables and throws off the maps in the ecu (like with the Mazdaspeed CAI that was recalled). The other important thing is the air straightener - but only in the case of a CAI. (I know cobb has an air straightener on their SRI, and cp-e ended up putting one in there as well just because cobb had one. But even if cobb had it - that doesn't mean its necessary)

The mazda3forums, has a mazdaspeed section - which is, in my opinion a little better balanced, but the other forum might be abit more informative. Either way - I look at both, as both have their ups and down and occasionally a fair share of drama.

Frosty- posted:The StandBack seems to be used mostly by guys building dyno queens who want big horsepower and don't mind exploding engines. The AP is a far better solution for a more casual application with the availability of free OTS maps. Also the AP is cheaper, ultimately, than the SB and the FC flash and the PnP majigger and whatever else is necessary. Hah yes I do - as of not that long ago. Currently working on getting the Standback on the regular Mazda3 cars (I have one on mine) The arguments about the Cobb vs. cp-e - indeed are lead by immature, ignorant and biased people. The application for these products is the same - but more importantly, its defined by how far you want to go and how much you want to make. For true plug and play and simplicity (with the latest maps) - one goes with Cobb (like yourself). For all out tunability and control - cp-e. There are alot of people tripping over details - and forgetting about the bigger picture - the product itself and wether or not they need it.

It seems like if you wanted a stand alone system that lets you manage every single detail and has an awesome support network you would just go with something proven like the F.A.S.T. XFI, Big Stuff 3, Motec, etc...

The AP says 35mpg at 60 and ~30 at 65-70 but I don't buy it. I haven't gone through a whole tank of normal driving since I uploaded the new map, but stock I struggled to hit 25 freeway.

Thanks Kynetx for digging up that thread. I remember reading it back when you posted it, but I just didn't put two and two together. It looks interesting, but I think I may go ahead and plop down the money for the Cobb SRI. I don't have an extra airbox to hack up, and I don't really have all the tools I'd need. Didn't you say you're running the Stage 1 SF map with that?
