yup like 6x6 fukin crazy dude and uh no I never got the chance for the CDFP upgrade/ no idea what my AFR's were but im guessing they were lean as hell. That damn car. its not even the car its that crappy motor. fuck!

This sounds extremely fabricated and basically sounds like you are just making things up. You make it sound like mazda had other power mods, did they offer anything besides intake? I am curious. I know they had suspension mods and the like, but as far as power intake was all and it didn't last long. Is there a link that shows that it will be back in two weeks? They pulled it because they realized your motor could blow in this car from even just an intake. Clearly they ran the a/f rations and realized they made a mistake and were opening up themselves to huge liability.

I called Street Unit the day before Christmas and that is what they told me. 2nd or third week in January. Add to that my Local Mazda shop said they had to, I repeat, HAD TO, honor your warranty if you used Mazdaspeed parts. They also said they would warranty my car for everything if all I have is an intake. Call up Bob King Mazda in Winston Salem and ask their service manager and he will tell you the same thing.


I got the Dodge info from the Top SRT4 tuner in the country who unfortunately isn't here with us anymore, Mark Riley, Daryll Cox's tuner. I was working under him when the SRT4 came out, Randy will back this fact up. We even had his memorial at Daryll Cox's shop. He used to laugh at the staged Mopar kits, until Dodge gave him some input on them. Maybe he was misinformed in the beginning but I seriously doubt it. Ford currently has the same policies for its line of motorsport aftermarket parts for the GT500 so it is not uncommon practice.

Last I checked every MSCAI dyno did report about a 15 to 25 hp gain. If you take my 242 and add in the least 15 at the wheels you are very close to 260 at the wheels with no other changes. You had to up the boost to get the same results from an SRT4 with a CAI to see similar numbers. If you need more than 260 at the wheels for what you are doing then Mazda warranties are not what you need to be worried about. Most other cars don't pick up that kind of power from an intake alone.

maybe i have a boost leak because im only hitting 15 at most and i have a cai/dp/rp, seems like everyone i talk to there boost went up?

Also no offense dude but thats a lot of mods for no fp, shit even i need a fp

[ev0nstispanka]

i guess but it really isnt to me. idk dude pretty much full exhaust to me and intake. Its sad to me that a motor cant support so little. I think that even with the pump i woulda blown it. i didnt have any type of tune either. so complicated to me just doesnt make any sense. idk about the warranty issue but i think it'll turn out fine being that they told me about 2 months ago when i had it there for maintenence that the mods are fine. I did sign to that statement as well. so yes it was documented. o well they can still fuck me over one way or another. lol. I might end up getting rid of the speed3. Not sure yet. Still owe 20k.

[ev0nstispanka]

and yes maintence to the vehicle was up to date.

[4thStroke]

Its not that the engine cant handle the power, its that people are modding and not taking the precautions to prevent this sort of issue.

Loosh hasnt blown yet. I dont think anyone who has been AP dynotuned has blown yet, we're making more power than the fully bolted cars and doing fine. PDXImport has ran many track days and has put his car through a beating and hasnt had a problem.

We all know the stock pump isnt up to par, you even stated that car would hesistate when loaded down, thats a good indication that there is an issue.

Sorry bro, but you had it coming. Im glad its getting taken care of, though.

so your winstom salem dealer honors it, you are lucky, it isn't mazda policy to honor it. and you didn't tell me anything about stage kits lowering your warranty in decending order, again, made up. stage 1 srt4's are faster than mazdaspeed 3 with ms cai. and i will believe mazda re-releasing the intake when i see it. i don't know why mazda would tell streetunit they are re-releasing the intake. and it will still void your warranty per mazda, which the mopar kits did not do, per dodge. hell, i think mopar even sella a warrantied supercharger for the hemis now.

and the thing with srt4's thats cool, you can turn up the boost and your engine doesn't explode. intakes did nothing on srt4's, but an srt4 with a wga and more boost, which costs lest than the intake, would be faster than an ms3 with intake. and they would both be out of warranty, per the manufacturer.

false dude i beat down on stg2 srt4's with just MSCAI. so i beg to differ. but it was pretty close. even though some ppl tell me there are stg1's that can beat stg2's.

another thing is yea i did know it was just a matter of time until the motor blew due to the fuel issue.

[itzl0l]

....i think its the pumps. Some folks are making near 300whp with the stock pump and a fair amount of boltons. Some aren't...like me...all i have is intake and TBE....my fp drops to below 1000.....my pump is in the mail. If ur getting a slight hesitaion/jerk/stutter under wot ur pump was not keeping up at all.

[08_ms3_gt]

this thread has been an eye opener for me - i didn't realize the ms3 engine was this 'fragile'.

to quick ?'s:
1) with an intake (HKS) and BPV (Forge), i'm not really in need of a fuel pump, right?
2) earlier this week i did a shift from 6-4 and hammered it. the engine 'hesitated' but i figured the ECU was confused about me going from cruising to WOT; the hesitation time was about as long as when the DSC steps in, but the car pulled long and hard afterwards. is the 'hesitation' you talk about similar to this or while accelerating at WOT?

OP, i'm sorry for your loss. i hope your stuff gets fixed up under warranty and as quick as possible.

it sure sounds like you need a pump but idk how with only those mods

[08_ms3_gt]

so the hesitation immediately following my shift IS what people refer to? i just figured that, given the drive-by-wire throttle, there was a slight delay before the ECU figured out what i wanted.

i haven't logged/monitored my fuel pressure, but, as you noted, i didn't think i had enough work done for it to be relevant.

any other input as to what i should do? and if i am at any significant risk given the minimal mods? the only thing i've done that wasn't ideal is that i got on it a little bit immediately after resetting the ecu. that said, i didn't beat on the car at that time.

Log your pressure, it's the way to find out.

if when it stuttered was right after you reset the ecu that is most likely why, what do you mean by a slight delay? its not a delay but feels like you floor it and let off and floor again but the whole time your really wot

[4thStroke]

PDXImportRacer was stage 2+FMIC and BPV and tuned with the stock fuel pump and he would get high load hesitation. Once he upgraded his fuel pump, the hesitation issues completely went away and the car would pull like it should have. The logs showed fuel pressure constantly decreasing as the engine was loaded, and IIRC, it dropped like a rock. I think a lot of people dont understand how important the upgraded fuel pumps are. A proper tune is also very important.

QFT. Honestly, anyone modding should invest in a data logging device (dashhawk, Aeroforce, Dashdaq, etc). Best $ spent on my car to date. I understand much more about the inner workings now that I can watch what's happening! IMHO, of course...

Yep I'm making it all up then. Not going to argue with you. I guess you know more than Mark Riley (all the tunes in the stages are of his design) about mopar kits and you know more about Mazdaspeed products than Streetunit does too. I will take your word for it.

EDIT: Oh and technically they are all illegal in California from stage 1 on, so its a moot point for left coasters. It don't just downgrade your warranty, it down grades your whole vehicle to being non street legal. I don't beleive many dealerships in California warranty vehicles that are deemed illegal for road use.

i'm definitely NOT stage 2, i'm barely stage 1, which makes me wonder why i'd be getting the same issues that stage 2 cars are getting.

i'll start by getting a DH, it's clear that i should have one.

bf360, this was not recently after an ECU reset. i had reset the ECU probably 3-4 tanks before it happened. i understand what you mean by floor it+let off+floor again; here's what happened:

1) shift out of 6th
2) gas it to match the revs
3) shift into 4th
4) floor it
***hesitation, as in there was no initial 'flooring' that occurred***
5) engine kicked in

yea did it feel like traction control kicked in when you shifted to fourth?

yes.

[mr_mazda329]

Wow...After reading this thread, I'm going to log my FP on my Dashhawk. Tho I should have no worries with the FP and knock retard. I only have a Forge BPV, Cobb SRI, and CS CBE.

[ev0nstispanka]

yea dude i thought the same..i mean i dont even know another car that can take this little mods and need fuel upgrades right away..its absurd. i mean damn come on you would think a 25,000.00 vehicle would be able to but then again its f'in mazda's fault for building the best motor IF KEPT STOCK and the worse motor IF MODDED.

I might be way off here and if I am please correct me, but it doesn't seem that anyone one has a proven formula for this car yet. I have to admit that things seem to be taking off as we speak, but up till recently with a few finding from ptp and others no one really seemed to have had this car figured out.

I agree with you 100%. A proven forged engine would be running around with 30 psi pumping through it via GT30R or bigger turbo. Trust me when people start to turn up the boost with there Mazda motors your going to start seeing those go boom as well. Its only a matter of time.

sad but true.
