0-60 time

[Greenbread]

what is the mazda 3 0-60 time stock and what is it after wutever upgardes you have put on it (cai, catback and such)

[KpaBap]

Mazda3S

0-60 mph : 7.5 sec.(manual), 8.0 sec.(auto)

Next time, please bother yourself to run a google search.

[Greenbread]

well i wanted to no your actual results and after your upgrades

[mobomelter]

i don't have one of those cool computer thingies or a stop watch. if i did i'd tell you what a stock time is on the actual road. (posted times are probably from a dyno)

[mp5jeff]

if it's 7.5 stock then with a intake and catback id say 7.3...lol

[fam]

I added my backpack and some school books and my big butt, im estimating my 0-60 is around 14 seconds with a 20 second quarter mile.

ha ha wtf.

i know what youre thinking, whys my mazda nowhere near that fast, and l will spill the beans, ever since that episode of knight rider where Kitt ran on orange juice, i have figured out how to get SOOO much more rwhp. :-)

Knight Rider Rules! Bow To David Hasselhoff!

I've seen Car&Driver claim 7.4 0-60, other mags say 8.0, but that must be for the automatic (piss)

[RED SP23]

My SP23 car runs 100 Octane BP and has a K&N Air Filter. The car is noticeably quicker and more responsive than standard. Most testers in OZ claim that 0-100kph (62mph) is around 8.3 seconds.....mine IS definitely quicker than that and is also more responsive than my other car (wife's) 6Speed manual Honda Accord Euro [..your Acura TSX](again K&N filter an 100 Octane) Especially quicker down low where torque and gearing count. The Honda is definitely quicker at higher speeds when the iVTEC is working. RED SP23

[mobomelter]

isn't 100 octane racing fuel? why are you running that through a stock engine?

[SP23goesroar]

is knight rider on anymore?

[mobomelter]

is knight rider on anymore?
no but the first season is on dvd.

[M3 5MT]

Most reviews will also tell you the 3 sprints to 60 quicker than the TSX. And you should be careful running 100 octane through your engine, it's possible that something bad could come from that, so I've heard.

[RED SP23]

Sorry..98 octane BP Fuel not 100 octane..I was thinking of my Shell A Racing Fuel I used on my Torana XU1 (32 years ago). BP have 98 octane as Premium unleaded fuel. No problems at all but it sure works. RED SP23

[RED SP23]

In OZ the best time posted in car magazines os to 0-100kph (62mph) for the SP23 in 8.3 seconds and the same magazines give a manual Honda Accord Euro (TSX) as 7.8 seconds, half a second is quite a distance at 100 clicks. I own both and both are quicker than standard using the 98 octane and the K&N filter. RED SP23

[mobomelter]

ok just checking about the 100 octane. thought that was a little wierd.

[RED SP23]

Ah... I love the smell of Shell A Racing Fuel in the morning. What a wonderful smell! RED SP23

[M3 5MT]

Wow BP has 98 octane? I remember when my town use to have a BP, but I havent seen them up north in years.

They use a different method to calculate octane down there. If you compared the two actual fuels (Oz premium using the RON method vs. NA premium using (R+M)/2 method), they would be approximately the same.

If you compared the two actual fuels (Oz premium using the RON method vs. NA premium using (R+M)/2 method), they would be approximately the same.that's what i was going to say. plus any unleaded fuel shouldn't hurt your car, and leaded only kills your catalytic converter, neither will do anything real bad to your engine

Thanks for the info. RED SP23

Octane makes sense if your car is tuned to use it.

Octane alone is not going to ruin anything.

If your car flows more air than stock, has a aftermarket exhaust etc, a little more octane will help you avoid an overly lean condition.

[majic]

our cars run rich as it is.. so there's no point of going more than 87octane.. CAI can actually help u with MPGs as long as you don't WOT it all the time :p

[goldwing2000]

Actually, that's not true. My girlfriend ran 89 octane in her car that was designed for 87 and after about a year, the spark plugs were completely burned out.

[Screamin'3]

For the most part I believe octain relates to the ignition temp of the fuel. ie. the higher the octain number the higher the ignition temp. In engines that have high compression or high engine temps require the higher octain to prevent detonation.
If you use a higher octain than your car was designed for there won't be much harm, probably not much good either. And your car may be harder to start on very cold mornings.

[M3 5MT]

I've been told that a higher octane rating means the fuel burns more effciently, meaning it ignites quicker, which means the engine should run smoothly especially when pushed. I've never heard of it having bad affects unless it was close to a rating of 100. I'm only basing this on what others have told me.

[goldwing2000]

The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. Has nothing to do with efficiency. Here, read this:

This one's even better:

Here's one from the Federal Trade Commission:

[Greenbread]

wait so if u got an intake and after market exhaust still only use 87?

[goldwing2000]

Yes. Neither of those things affect your compression ratio. The only "add-on" that you'd need a higher octane for is forced induction.

[M3 5MT]

The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. Has nothing to do with efficiency.

"So we want to match the correct octane rating of the gasoline to the engine design to ensure complete burning of the gasoline by the engine for maximum fuel economy and clean emissions."

I was wrong in saying that a higher octane rating is more efficient. It is infact the opposite. Using a higher octane rating when it isnt necessary will cost the user more money. That's not very efficient.

Using higher octane means>Better Gas mileage!!!! I have drove from california to washington state a few times. Going from fresno to redding i got about 28-29mpg on unleaded fuel(87octane). Then from there i filled up with premium unleaded (91Octane), and notice a big difference in gas mileage i got 454miles on a tank filled up at 12.4**gallons= to about 36Mpg. Now that's a big difference, "using higher octane doesn't necessarly just mean better performance, it also mean's better fuel timing/spark!!!!

That's what I had claimed in my previous post. The link goldwing2000 posted said the opposite. At this point I dont know who to believe.
