Extra HP, what have you done?

Looking to get a little more zoom zoom. I'm curious to know what folks have done to squeeze more horsepower out of their 5. Thanks for any input.

It really sounds great, but no real gain in power, maybe 5 to 7 WHP... lol

If you want some real zoom zoom then drop it about 1.5 inch and put some nice rubbers on ;)
 
I'm new to the 5 but intake and exhaust are always the bang for the buck. Anything more costs alot and gives little. An air filter in any configuration is your first and best bet. A cat-back system is next and then after that.........you void your warranty for an extra 3 hp lol.
 
Smaller diameter tires. Same as lower final drive gear ratio but a lot easier and cheaper. Lower gears are often overlooked now-a-days as apposed to intake, exhaust, engine mods (all good). A lower final drive ratio will get you through the 1/4 mile faster than stock gearing. Unfortunately with todays front wheel drive systems it is not as easy or cheap as swapping the crown and pinion in a good ol rear drive pumkin.

but it doesn't give you any more horsepower. yes, it lowers your gear ratios, at the expense of an inaccurate speedo, and making 1st gear almost useless. as it is, mine zips to 7K REAL quick in 1st gear, and 2nd pretty easily. why would I want to make that worse AND lose some hwy cruising ability?

my advice would be, as stated, an intake (not worth too much) and a cat back. after that, perhaps a header.

remember, these cars are boxy six passenger people movers, they aren't race cars.

Yea man, these are boxy six pass. wagons that aren't race cars. How come some people make them look like race cars? Back in the day if buddy had a Chevelle with a six in it and he jacked it up, put on mags and a spoiler we would laugh at him like Homer and Bart. Now if he also slapped in a 409, that would be cool. Maybe I am old school, but if your ride "looks" faster than stock, it better be. Now don't get me wrong everything looks better with some nice rims etc., I'm talking about some vehicles I see around with everything in the catalogue hanging off it and nothing is done to the motor?? Anyway I digress. When new tires are needed on your 5, you could opt for smaller diameter ones which would give you faster acceleration and the likeness or feeling of more power. Not just in a "drag race" but cruising through a mountain pass or where ever, you would have a more responsive ride. You will loose some fuel milage and your speedo will be out a bit. Personally I don't care if my speedo is out a tad. Who the H... goes the speed limit? Adding a proper CAI and exhaust ain't cheap and would only get you a few extra ponies. If I had the money kickin around I certainly would add the CAI and exhaust but I can't justify spending almost a grand for a few horses. Now a turbo.. (picture Tim Taylor "OhOhOooohhh") With the lack of raw power in the 5 everything helps, but as you stated it is just a people mover, one has to weigh the pros and cons of their chosen power adders.
 
The 5 comes with 50 or 55 series tires. Lower profile (smaller diameter) tires would not likely fit on the stock rims, so it would not be a cheap fix to lower the final drive ratio.
 
The fs-de is slow. Upgrade your suspension/tires or add boost. Other than that, buy a better performance platform. :)

Intake/header/exhaust will give you ~5whp. Only *noticeable* gain is possibly throttle response, and a bit more pull up top. The best mod bang for the buck wise is to re-flash your ecu with that of an MP3. Should give you ~7 whp or so. Someone on these forums does it for $150, IIRC.

Ultimately, unless you go F/I, you will end up disappointed with the money you put into N/A mods. Unless you do some serious modifications.

O, and try the forum's SEARCH function!

A "proper" reflash will cost you about $500.00 and up. You will also have to run 91 or higher octane fuel. This gets pricey for what the vehicle is. You could reflash to run on 87 octane but the gains are not nearly the same. As you said, just get a better performance platform rather than spending tons of doe on a 5.
 
No, those types of reflashes are not offered and are not beneficial on the fs-de. These aren't VW's or BMWs, lol. getting 60+hp from a chip. (rofl2)

The MP3 is just a higher trim level protege. It had a different ecu fuel/air map with a much better and smoother power band. It's not the type of reflash like you're thinking. It's still a Mazda ecu program. A member of these forums happened to obtain the fuel map and software to reflash to those specs. But yes, if you use 87 octane fuel, the motor will knock and it will retard your timing losing any gains you got from The reflash. You must use 91 or higher.

$150 for 10 hp (~7 whp) is a pretty good gain. Beats the hell out of $400+ for ~3whp with an exhaust.

Read more, preach less.
(attention)

the fs-de has no talk in this thread...this forum is for the mazda5...not the protege5

you throw this out there.....reading fail on your own part lol.

haha, looked like p5 to me.... ty for letting me know that. I really need to work on my reading skills. Well, haven't failed this hard in a long time. I guess thats what I get for procrastinating at work for half of my day today at work.
 
Always nice when the MSP/P5 crowd slums with us lowly 5 supporters.

I feel naked without a turbo, dammit!

STICKERS!!!
