Suddenly there is a bunch of COBB in my Daily Driver
 

So I bought this 2013 Speed3 as the daily driver, thought it would be fun and get me out of traffic on occasion. It looked Stock, but after some looking it was pretty easy to see that it had been modded and returned to stock. It was fun the day I bought it, I did have some boost control issues, fixed by changing out the hoses on the controller.

Interestingly, for the daily driver, I seem to have gotten a bunch of COBB stuff and even some CorkSport.

I am really Liking it and I have a three port boost controller on the way.

Looks like you've been bit by the mod bug. Watch out bank account

No doubt. I spent around $2k within 30 days of picking up my speed. I need to get one of those hood scoops.

What do you need a 3port for?

Need? There is no need involved, it is a want. I want one because I can use it in interrupt mode and have a more stable and exact boost, Less spiking and with some work on the tune, especially in the waste gate port area better consistency.

Ay least that is what I have read.

The hood scoop is from CorkSport.
2010-2013 Mazdaspeed 3 Hood Scoop

It was out of stock when I wanted to order, so I got the "Factory second"
2010-2013 Mazdaspeed 3 Hood Scoop for Painting

This one has small "cosmetic blemishes" but it was in stock. I used lots of clear UV protectant spray paint sanding between coats and it doesn't look bad, if you look close you can see the "cosmetic blemishes" but it doesn't bother me. If it ever does I will just pop it off and use a little filler and paint it gloss black. But right now it is fine.

Yes, but I think as long as it is the daily driver the only performance mod, after the three port boost controller will be the cat back exhaust. That will wait a while as the current one is looking a little rough, so when it fails or I have cash to spend (maybe a Christmas present from Santo to Me) I will get it. I think that is more about sound and looks though.
I think I will not exceed the "Stage 2" if you look at the COBB performance staging.

I will however keep hot rodding the little Miata :yup:

The CS scoop in on my list. I intend to have it painted VRM, but may put it on au natural to see if I want to keep it that way. I already ordered new washers for the scoop and have a ETS TMIC that I plan on installing with new plugs on Monday.

Suddenly there is a bunch of COBB in my Daily Driver
 

A Cobb cold air box? Don't see that around very often. Did you have to add another layer of clear coat?

I didn't do anything to the Airbox, it sounds good. There was no need to paint it.

I did use several coats of clear on the hood scoop.

Well somehow I got some more CorkSport in The daily Driver.
Got the three port installed, got the basic tune put in and will check it out more tomorrow.

It's pretty tight trying to get the boost controller in there without taking some additional stuff off to get some room to work.

Cool, I meant the hood scoop.

Like I said above I bought the "factory Second" suitable for painting, it was in stock and a little cheaper. When it arrived it looked pretty good but you could see some very minor issues. I decided to try a little sandpaper and UV protective clear coats. While it isn't perfect it turned out pretty good, especially after using some polishing compound, cleaning and waxing.
If I decide later to paint it I won't feel bad, that I paid for the other one. :01:

I really Like the CorkSport 3 Port Boost Controller
Using it in Interrupted Mode seems to have made a big difference.
I am still dialing it in, but real close, didn't take all that much work, a few WOT runs after reducing wastegate duty cycle by 40%. Working the WGD up a little at a time till I get to the Boost targets. I am currently within 1 PSI of boost targets now, just little more dialing in for a few cells.
However, there seems to be much less fluctuation in boost pressure. Currently max boost is set at 18.5, Max I am getting is 19 so I need to dial the WGD back a little in the 3600-4100 RPM area.
So Like I said, I like it a lot.

Something looks wonky in that log. First of all, your VVT doesn't seem right. Normally it is high (30's) and drops to 0 as boost and rpms rise. Also, what's up with your AFRs? In the first gear they look ok most of the rpm range, still very rich (too rich?), but then they pop into oscillations at the end and thru the second gear rpm....

I've not seen that before, but would start with a MAF cal to get the stable AFRs more in line (I assume you would be targeting something like 11.4, not 10 or lower), then see if the oscillations go away. If not, look around for a lose connection or post up a new log to see if folks can help

VVT, is that the Intake Valve Adv. (°)? I have seen this about 28* at low RPM, not sure why it is not showing in this particular log.


I know the AFRs are low, this is the COBB Stage 2 93 octane map, the only mod was the waste gate duty. I have been working on that as I go. It is better now.

Thanks, I will likely do the MAF Cal, once I get some time with the car. I didn't think I would have to do it using their map, and their intake but it looks like that might be needed.

I was really considering the CorkSport hood scoop when I had an ETS TMIC, but then I setup a custom FMIC setup. I think I'd feel stupid going with the hood scoop given no TMIC to cool off. It seems like it would just be an aesthetic add-on at that point.

However, I've considered making a fiberglass-molded plate attached to the underside of the hood to let the hood scoop suck heat off the top of the motor, and force it back towards the exhaust manifold. That... with baffles to make it so rain water doesn't spray all over the valve cover and IC piping.

I seen some with FMIC setups just block off the inlet on the hood scoop, but wondering if anyone has made if more functional for at least heat removal.

"I think I'd feel stupid going with the hood scoop given no TMIC to cool off. It seems like it would just be an aesthetic add-on at that point."

Dude, if thats a pic of your speed I can't imagine you'd have any issues with aesthetic add on's.... not that there's anything wrong with that

@Scaytale; I was going to say, you can do the EGR delete to get a little more room around the turbo intake and EBCS....

Plus, the benefit of cleaner valves :-)

I might do that later, I probably need to clean the intake vales soon as the milage is getting to 50,000 and the idle is not as smooth.

158k here and never cleaned my valves. Car runs fine.

Do you have the EGR delete? or use water/meth/fuel injection in the intake manifold?

I understand that adding a fuel or water to the intake, so that it washes over the valves should keep them clean. I'm not interested in doing that to my daily driver. I may use that idea with water or seafoam and see if the idle improves.

Probably let it go unless it gets worse.

Nope. Making 375whp last logs I checked. 20psi on a gtx3076r/ewg stock catback too.

Thanks that is helpful.
I do have a rough idle but I am going to do the MAF recal before I get to worried about it. It isn't real bad but I notice it.
I will be happy around 300 and I am planing on staying with the stock turbo, at least until it fails. It really is the daily driver.
I am also trying to run 20 PSI but no more than that on this turbo. My exhaust is stock from the catted downpipe back, plan to leave it that way. I did get a 3 bar MAP since I am trying to run 20 PSI.
Again thanks for the info.

I'm guessing there's a Cobb AP amongst all this somewhere?

You shouldnt need to the 3 bar MAP to run 20psi.
