New dyno numbers 309whp 361ftlbs.!!!!!!

[driver311]

Thats right. This graph mods are test pipe, then added bc set at 17psi. and spectra short ram. Still has cat on it so afr's show about 1 full point lean. Im totally stoked on these numbers. Boost spiked about 21psi on the dyno and held at 17psi strong. Car flat out rips.

modded stock box no fitler vs. spectra short ram. I also did one with the filter and it was 308whp. 365ftlbs. stock box run was started a little earlier in the run and thats why the boost comes on sooner. though peak power and torque were up. spectra held the topend better and was alot leaner. im thinking its the bigger maf housing. Im running the spectra until I go with the cobb sri. I think cai are overrated. ive never seen more power on the dyno or et on the track from a cai. Just my opinion. Once the car is rolling sri is not an issue. Its just simple logic.

very nice, sick torque

[oskinosmee]

Damn Thats nice

[MS3-oholic]

Your afr is showing somewhere around 13:1 . Be careful. Also, why would the cats show you running leaner, wouldn't it be the other way around?

[driver311]

No the cats burn off unburnt gas. So is actually in the high 11s. Besides I put the modded stock box back on and the car dynoed 311whp and was back in the low 11s for afr. So I left it. I just havent posted that graph yet.

[Turbo 331]

Any vids???

[Turbo 331]

Also, How is your trans holding up to that power? Is your car a highway killer or strip? I ask because i would think with the power u have you would rip the trans apart if u raced stop and go all the time. I can see where you could get away with it on the highway

So you actually did slightly better with a modded stock airbox?

[driver311]

The peak numbers were better along with the low to mid power. Held better from 5k to 6k though. 5-10whp or so with the intake.

[laloosh]

i told you people using a simple mbc does wonders....great numbers

[BluMicaR]

i told you people using a simple mbc does wonders....great numbers

Is it safe to run an MBC though? I mean 5 years from now, shooting for owning it forever, 100k-plus miles safe? I want to keep my car around and together without any major mechanical failures that are due, at least in part, to me.

[laloosh]

yes it is...the car is not running lean, its not knocking, its not doing anything out of the ordinary except running alot faster lol. i find it kinda funny how people with bolt on and ems cant even get these kind of numbers lol

[clos561]

some havent dynoed...

[tru-boost]

hhhmmm i'm skeptical. it seems very high. my car at 18psi dynoed
269hp/332tq. on a very agressive AMS dyno. i just dont think 17 psi with a test pipe and air box mod can make this much power.

LALOOSH...... please go dyno your car !! if these kind of numbers are realistic, i dont need to spent a ton of money on an EMS ! i need to see more than 1 dyno to make me believe. i would much rather spend $100 compared to the standback price if i can get the same results !

[ispypsi]

he did say it spiked, so that could be the reason those numbers shoot up so high in the beginning. still great numbers, but i would want to see how they level out without the spike.

[pHeeL tHiZ ViBe]

direct injected motors are designed to run safely with extremely lean AFR's. just a BTW, i'm not saying its good to (hah)

[Vindikacione]

Where do you buy a Spectre short Ram intake?

It does make you wonder, doesn't it. I know that BEGI said that a major source of the power increase with the XEDE was just running a consistent boost, I think they said they were running 15 psi. Timing, etc., really didn't come into play that much. CP-E touts the benefits of a more consistent boost also., It seems too simple, but you never know.

That is exactly correct. Boost spikes hard then holds solid at 17-18psi. I love it that way. So everytime you hit the next gear it gets an instant torque spike then pulls through the rest of the gear with whp. Like I stated before the car made more power and torque wiht the stock box and afr's were alot safer. Ill post the graph asap.

dude im me at xclaloosh04 i wanna pick your brain a little

[LENNY127]

all I can say is run er hard and let us know what breaks first. you guys are more adventurous than I am , I want to make it faster but not at the cost of reliability....only time will tell I guess....good job though keep knocking off those tenths.

[Captain KRM P5]

not THIS lean they're not. he doesn't even hit 12:1 air fuel ratios until just shy of 6000rpms it looks like. there are people with built engines that won't run them that lean.

good numbers, but be careful. i'd say that AFR is way too lean to be safe in the long run.

[driver311]

other graph is up.

Car is in the low 11s for afr. This sniffer is just way off especially with a cat in the mix. I already stated that.

[Captain KRM P5]

you have a wideband after the turbo to tell you its at 11:1? or how are you reading that exactly? sorry if i missed it. in my experience cats do not throw the AFRs off to that extreme, a half a point at the most.

[driver311]

lm1 closer to the cat. reads in the high 11s with the spectra intake, and high 10s with stock box.

so i figure low 11s with intake and way to rich still with stock box. lol

[Captain KRM P5]

before or after the cat? if thats before the cat those are pretty damn good AFRs.

[driver311]

no its just after the first cat. second cat is gone, test pipe and o2 bung replaced that

[driver311]

once I get some kind of engine management and a downpipe I will tune it to 11.8ish on pump and 12.5ish on race gas. Very soon. Also plan on a upgraded tmic. I think I like the extra spool time that the tmic offers over he fmic.

Cats don't burn off unburnt gas. They provide an environment for a chemical reaction (http://en.wikipedia.org/wiki/Chemical_reaction) wherein toxic combustion by-products are converted to less-toxic substances. (Thank you Wikipedia! :) )

[fourthmeal]

FYI it is found that a cat, due to the heat retained within, can burn off unburnt hydrocarbons, which would change the AFR measured by a wideband.

well i think being direct injected gives us a little extra safety
Wiki Gasoline Direct Injection (includes Mazda DISI) (http://en.wikipedia.org/wiki/Gasoline_direct_injection) i really don't know much about it though, has anyone actually blown a mazdaspeed6 or 3 motor from running to lean yet? i think there have only been overboost issues ?

yes and no. being direct injected isn't a get out of jail free card to run a great deal leaner. overboost is simply one condition out of many that can lead to a leaner air fuel ratio. too much air + not enough fuel.

keep in mind there is more to being safe than a good air/fuel ratio. EGTs have a lot to do with it to. the higher the exhaust gas temps, the higher your combustion temps are. the higher the combustion temps are, the closer you get to things like detonation, ring gap clearance issues, melting pistons, etc etc.

if it were only a matter of having good AFRs, it would be easy as pie to get alot of power out of alot of different vehicles.

[pHeeL tHiZ ViBe]

true, true..

hey everyone thats ken ^ he knows the shit ;) lol

[Haltech]

If i was you, i would get a meth injection kit. You will bring those AFRs numbers down and cool the motor at the same time. Not to mention, put down more power.

[driver311]

thats some good advice and thats exactly what i have planned. More to definately come. LOl

me...and it happened on the 2nd WOT run

[pHeeL tHiZ ViBe]

lean from overboost though right?

[controlo]

lean from overboost though right?

yeah, what exactly would cause his car to run lean? boosting 18psi? i have an injen cai and a PG test pipe, i wonder if my A/F's are safe...

MBC sounds like fun.

haha.

[Focused]

Maybe I'm thinking of somebody else, but wasn't the bigger turbo bolted on when the motor blew?

[Haltech]

If youre talking about the MS6 that blew, yeah, he had an ATP on there as well and never tuned it.(nervous)

[tru-boost]

meth is a pain in the ass on a street car. been there done that, not on this car for me. you have 2 options with meth. run it all the time and have to constantly monitor the level, cuz if it runs out on you while you are running high boost and extra timing... you gonna have a problem ! or.....
have a seperate tune to use when you want to use the meth. that to me is the smarter option. the issue is having to to deal with swapping between 2 different tunes, depending on how you feel like driving. its a great mod, with great "bang for the buck" its just a pain in the ding ding to deal with.

I dont really agree with this statement. First off, you can get a stage 2 setup that runs off the voltage on your MAF. The only time its going to spray is how you set it. Generally, a 3V+ is when you want it 50%.. by 4.5V+ you are 100%. Youre not in constant boost anyhow, its mainly short spurts unless youre in a race and even that wont put a huge dent into the amount of fluid youre using. Common sense tells me if youre running high boost, youre going to be in tune with your stuff, including the meth tank level. For $20, you can add a level indicator to warn you of low fluid. With these piggy backs, you can switch tunes on the fly, so having a seperate meth tune is simple if youre that paranoid. Theres really no reason you cant get at least 2 gas tank full (450-600 Miles ) before having to refill the meth tank. Ive been running meth in my vehicles for well over 15 years without any complications or inconveniences.

[driver311]

i plan on it none the less. I see no reason why with tmic, downpipe, and meth kit at 20psi I will be pushing 350whp all day long.

[clos561]

boom boom all day too

[poof100]

How about some fuel system upgrades?? Do we know the limits of the stock fuel pump? What about injectors?? Then you get the limit on the Rods, which aren't forged.

[clos561]

protege garage topped the speed6 at 394 tq on stock fuel system, they running vta so they can get as much fuel as possible from the stock system, so thats probably the max since they cant seem to get more power at the moment, not enough fuel

[pHeeL tHiZ ViBe]

hmm...why do you think they are discussing meth injection??? haha

well keep in mind a few things. we're not currently running vent to atmosphere on the car. we did so to test if indeed the car was incapable of adding more fuel. the car did richen up after we went VTA even at that power level so there is some evidence to state that if the fuel system is properly tuned there is room above what is considered 'maximum'. like you said, these numbers were on a mazdaspeed6. had they been on a mazdaspeed3 i'd think you'd see alot more power due to less powertrain parasitic loss. we haven't made any attempts to garner more power out of the car because the clutch is currently fried in it, replacing it is a 9 hour job and we've been backed up otherwise. the 394 lb ft of torque was done on a street tune no less, so once we put it on a dyno things could be interesting.

[clos561]

i cant wait for the 400tq breaking point... sick ass all wheel drive launches...keep up the good work btw

[lukey]

how much torque is the stock clutch actually rated for?

[pHeeL tHiZ ViBe]

like 2hp (silly)

it blows, mine slips so bad if i try to launch above 3k..of course i put some wear on it. but it never really 'hooked up' very well, even when i first got the car.

[mazdaspeed32007]

the stock clutch, if im mistaken correct me, but i believe its good for around 450 hp. dont shoot me if im wrong. i heard it somewhere...just remembering....maybe. lol.

[Captain KRM P5]

i think the factory clutch will melt by the time you hit 450hp honestly
