Questions about MS3 Turbo Performance

Ive noticed that when I request bad ass power from my MS3, sometimes my turbo kicks in a bit harder than others. I dont think that there is a problem with my engine or ECU, but rather, it might be a function of what RPMs Im driving at when I start to accelerate, how fast Im already going, what gear Im in etc. Sometimes when the turbo kicks in Im like holy **** and sometimes Im just like thats pretty good. I havent experienced any engine hesitation or weirdness, so I really think that it might be the way that Im driving the car. I usually do the power tests rolling @ about 30 40km/h in 3rd gear starting at approx 2800rpm as that seems to be the money gear for raw acceleration, and Ive tried different styles of acceleration like 100% throttle right away or 80% throttle up to about 3300rpm then 100% throttle. I know that maximum power is at the 5000-5500rpm mark, but it seems like maximum acceleration is in 3rd gear.

Really, Im just wondering what is the best way to get the most out of the turbo on the MS3 and are there any driving techniques that will maximize the engine performance. Also, I havent tried doing hard accelerations with the DSC off. Will doing this increase power output or have adverse effects on my engine/drive train? Another thing is that Im probably getting used to having 260bhp in a car, and the power doesnt seem as awesome any more. But I swear that I can tell a difference from one hard acceleration to the next.

FYI, this MS3 is completely stock.

Any feedback or suggestions would be greatly welcomed!

Thats what I thought 2 (then I drove my girls scion TC which is faster then the ford focus I was driving b 4) yes the MS3 is F-ing fast.
I think what's happening is your learning how to control/drive a faster car, making it seem that the car is not as fast or losing HP.
Trust me...drive a slower car for an hour, then drive your car again and you'll be like damn this thing is fast.
Sometime's I feel like I can control even more HP. But one thing at a time
 
From what I have heard is that 1st and 2nd gear are limited to 5 psi. This is to control the torque steer. I am not sure of this fact but have heard it from a friend of a friend who used to date a friend whose dad had a friend that works at Mazda.
 
1st gets 10 psi....2nd gets 13. the rest get about 15-16 with some spikes to about 20. the car is ecu controlled. it will do what it wants when it wants.
you will most likely never get the same results twice ! it has a mind of its own.
 
Plush, I noticed the same and some times do different "tests". All I can tell you is that full throttle is not a good idea until around 4k rpms. I almost always get better results by doing 50 -75% throttle to get the full benefit of the torque. All this is thanks to Mazda's tq steer controls.

Oh, and get a cai fast, that would bring back the "holy ****" factor. (yes)

i thought it was 8 psi and 11psi then 15 and 16...thats what i got
 
if your in the cars powerband its going to pull stronger then if your coming up in the rpm from outside the powerband. there is also alot of contributing factors like if your cars temperature/timing/humidity etc
 
You know it really matters if the IC is heatsoaked or not, too. I've found that to be a problem after idling for a bit, or in stop/go traffic. When I spot a clearing, and gun it...I get something quite a bit weaker then I am used to.
 
It's been hot and humid as hell here lately (Indiana) and today it's only about 73*, we've been touching 100* last two months, and sticky as a movie theater floor. I was just running home and back from work, and my baby is really digging on cooler temps and low humidity. Aside from that, I don't have the a/c on either; it was a very noticeable difference! I can't wait to get my CAI, TMIC, Turboback, and Port/polish. Thing is going to be a cranky little a-hole of whp!
 
redspeed is on to something I think. Third has always *felt* faster coming out of a hard shift from 2nd - and of course that might just be the kick from the clutch engagement, but we also know that the MS3 electronic throttle control means, "flooring it" doesn't mean the throttle actually opens all the way, the Turbo Czar under the hood has to deemed you worthy of full boost at that particular moment, so your performance impressions may vary. IMO and IME, the irregularity in power is... thrilling but sooner or later just dangerous and makes me wish i just got a v6 something instead.

3rd is definitely limited too. I don't think it will go over 15 or so. It may just the throttle plate as opposed to boost limited. I can tell you, though, it's absolutely killer with the Xede and I imagine with the CPE as well.

5 psi? Maybe you're thinking about the MSP.

CAI, TBE, Motor Mount, Standback, Meth/Water Injection, and youll have 400+ crank Hp and about 355 WHP. its been done...its been proven. same price, well worth it.

Yeah, just one thing at a time, I'm waiting to see what Cobb will bring to the table, and what the gen 2 standback looks like.

C-PE's new standback is coming out in a few months. they actually release their products. the new version allows you to not only control everything you'd want to in the car, but also the throttle plate which everyone has been dying to change since it just decides to shut down at key points.... aaaand its pretty f-in affordable especially in correlation to doing what it does.
 
per CP-E's unofficial press release provided here on the MS3 forums, the throttle plate will be controllable on the new model. As a nice bonus to those who already have the older CP-E standback, they will offer a module that allows it to control the thottle, AND/OR be able to upgrade to the newer version at a reduced cost.

That is pretty amazing, to me.
