CPE performance upgrades

Shadow - any dates on release of that corksport tbe?

And i agree with you, owning both a Evo and a cx-7, they are 2 different worlds apart. I enjoy both for what they are; the cx-7 as a great daily driver and transort suv, while the evo a visceral rally bred sports sedan.

Corksport supposedly made the prototypes back in May. No clue as to when they will release production parts. I emailed them back in May and they didn't give any dates. Personally, I would have preferred a catless midpipe over a catless downpipe (or a 2 piece midpipe/cat with a HFC or test pipe option). First, it will be a 10 times easier to install. And secondly, it will not trigger any CELs. However, Corksport says they will be incorporating a mechanical CEL fix in the O2 bung of the downpipe. Too bad, Mazda did not manufacture the midpipe with a separate 2nd cat like on the MS6. Then we could just install a test pipe without any fuss. But nooooo, they incorporated the 2nd cat and midpipe as one big piece.

Corksport will be releasing a catless downpipe and an axleback muffler system (retains the stock midpipe/2nd cat combo). A 3900 lb SUV will likely never be able to run with 3200 lb Evos and STis. The MZR motor just doesn't make more power than a 4G63 or EJ25 respectively.

Having both they are no where close to each other....but you knew that already.(flash)

What's up with people having both an evo and a cx-7?? I should start a new fad and own an sti and cx-7!

 

[shadow1]

An STi and a CX7 would be an excellent combo in the driveway!

Speed 6 and CX-7... keep it in the Mazda Family.

CX-7 and turbocharged RX-8 is even more fun (breakn)
They mach pretty nicely

What turbo are you running in the RX? Greddy kit?

 

[MadMax1]

Ill add CX-7 little modded, and a 00 Subi Imp Rs with 06 usdm wrx engine swap

A little ot here, but the evo is hard to beat price / performance wise. There is such a plethora of aftermarket as well as community support that most things are very very cheap. Not to mention its rock solid relaible engine foundation in the 4g63 and the ease of mod installation and tuneabilty (i installed my aftermarket turbo and tuned it using free open software). Where it fails miserably is in the creature comforts such as antiquated interior design, radio, and NVH levels. That's why the cx-7 to me was a natural compliment.

 

[Rick's CX-7]

Well thanks a lot for your input guys, this is exactly what I'm looking for. We need to know if you guys would consider a turbo swap, and it looks like that's a little more headache than you guys are willing to endure, which is fine. Now that we know this we can concentrate on optimizing the stock turbo setup.

We still have to dyno tune BadakVT's (Mike) car, so we still may gain a good amount of power over the stock tune. Mike said that the car feels stronger with just the boost control enabled at 16psi, but we still need to tweak the timing and air/fuel. So we're going to try to get him on a dyno soon.

Jordan,

Put me in this group too! Turbo swap might be too much....optimizing the stock set-up will be much more appealing to most of us here.

Don't know if you know much about oil analysis, but it seems your assumption that the CX-7 might be "pig-rich" like the MS3 and MS6, is true. Those two oil reports are from my CX-7 and it's not looking good. Massive amounts of fuel being dumped "directly" into the chambers is not a good thing. Thankfully, wear doesn't look to bad. I can e-mail you the two full reports if you think it'll help!

No wonder we get such crappy MPG.

 

[jestermsp]

what is the status with this ems anywho. corksport will be releasing the exhaust soon and id love to pair em up! still lookin for dynos!

Hey Rick, this is is actually a common issue for the MS3/MS6 as well. We have our guesses as to why Mazda tuned these cars so rich, but luckily the rich mixture is only present during wide open throttle. The Standback can lean the mixture out at WOT, which would also limit the fuel that makes its way into your the oil. At cruise however, the CX7 runs at a perfect stoich mixture of 14.7:1. When we get Mike's CX7 on the dyno we'll be able to see exactly how rich it is at WOT. But if it's anything like it's Mazda cousins, it'll be as rich as 10:1 towards redline (crazy)



And I apologize for the lack of updates lately. We've been tremendously busy here at the shop, and we're waiting for some down time before we tackle the rest of the CX7 Standback project.

We'd like to get Mike back in the shop sometime soon so that we can dyno tune his CX7 and see what kind of power we can eek out of that platform. So this CX7 project is still on our radar, but we're waiting for a little down time. I'm going to be in contact with Mike and see if we can figure out a time when everybody is available to we can start tinkering again. I'll share our timetable with everyone once I get a hold of Mike.

I'll probably be one of the few considering a turbo upgrade in the future. I don't think I'd mind raising the boost threshold a few hundred rpm to gain a lot more in the upper end. Until that time though, I'd love to make the current setup perform as well as it can.

Excellent! I think we're going to be releasing some bolt-ons for you guys in the near future, so you'll definitely have some product choices to help maximize the performance potential of the current platform. I think we'll have some more significant updates in the next couple weeks.
