Highest HP 5?

[twintrbo]

Who out there has the most engine modded 5? Just kicking around about having more power and I want to know if anyone has dynoed their mods and knows what is possible? I want to do some mods for mine but I will not void my warranty or sacrifice much OEM noise levels or driveability. Kicking around on the 3 forum it seems the most gains would be from:

New Intake/Filter
Hypertech chip
Cat back Exhaust
Throttle Body Coolant Bypass

Not sure if these are possible with our cars, but:
Timing advance
Ignition upgrade
Larger Throttle body

Other considerations:
A header would be good but I dont know how loud it would be.
Balance shaft removal but I like a smooth running engine.
Underdrive pulleys but the A/C needs all the help it can get.

From my years in the tuner world, experience tells me that with an NA engine once you get past intake and exhaust upgrades you are spending lots of money for minimal gains so I would not go too deeply into the engine mods. Thanks for anyones input in this!

Your experience in the tuner world gave you all the knowledge/answers you need.

Is that confirming my suspicions or sarcasm? I will always admit I dont know everything there is to know. I will always keep an open mind with an unfamiliar platform because different mods can have huge gains.

FWIW it looks like 200 HP will be a bit a of a stretch but maybe another 20 at the wheels would be possible without going crazy.

Depending on your passenger carrying requirements, you could pull the 3rd row seats and it would be like adding 10 hp. Dump the spare (add a can of tire seal) and add another 5 hp.

Thats very optimistic estimating. I cant imagine the third row weighs too much, maybe 60 lbs total and the spare about 15-20. So even at an inflated 100 lbs, the most it would take off the 1/4 mile is about .1 seconds. So thats about 3-4 hp according to the drag racing calculators. (estimating using a 3500 lb weight and a 78 mph ET)

I never stripped my cars at the drag strip, I wanted to know what it ran on the street, every day. On the other hand it would turn the 5 into a useful version of the BMW X6

I would really like to know how removing weight from your car adds horsepower... Increases your power to weight ratio sure but increase horsepower come on now.

he meant it is LIKE adding that much HP. the only time losing weight will give you HP is when you lighten up things on the engine itself, and that is technically freeing up HP lost with weight. aka light weight pully, light weight crank pully, light weight wheels, etc. there's not too much you can light weight on your engine but those little things DO help

Sorry that does sound wacky lol Its not actually adding HP, I reversed the equation to figure out how much more HP the weight reduction would be equivalent to. The same car weighing 100 lbs less needs about 4 HP less to do the 1/4 mile in the same time. Does that make more sense?(ricer)

 

[jimp]

I was confirming your suspicions, not being sarcastic at all. People over in the Mazda 3 forum spend $$ doing the exhaust/downpipe, header, yada yada yada, all the way up to a turbo to get more HP, but at big $$ IMO. And then the car doesn't run right half the time, etc. Just buy a MS3 and be done with it IMO. I couldn't tell you if 200 hp is possible or not, I wouldn't spend the $$ myself just because you'd still have a 2.3L mini van. Now put the MS3 engine in there, would haul some @@s.

No I'm NOT trying to sound like a dick, or asswipe, but...
you expect us to help you OVER THE INTERNET, treat us like crap and expect us to help you out?

a) Sounds like you need to stay over in the Mazda 3 fourms.
b) you won't "void my warranty or sacrifice much OEM noise levels or driveability"

Okay Mr. Zoom Zoom tell us HOW YOU'D do those and not spend a ton of money or KEEP STOCK SOUNDS, etc. ha ha ha.

New Intake/Filter
Hypertech chip
Cat back Exhaust
Throttle Body Coolant Bypass

Not sure if these are possible with our cars, but:

Buahahahaha! You're willing to waste $$ on a fat a$$ bi*&h of a car like the Mazda 5/Premacy ?? LOL! Yes, go back to Mazda 3 land and sell your 5.

A header would be good but I dont know how loud it would be.

WTF? Now you do want to void war. and sound etc. ???

Balance shaft removal but I like a smooth running engine.
Underdrive pulleys but the A/C needs all the help it can get.

I give up, go buy a Mazda 3.


Good luck!

Peace!(rei)

Well...actually Sarge, you kinda do.(confused)

After reviewing all the posts Twinturbo made in this thread, I read no crap or really any request for help. More like politeness and a request for info on what others have done to hop up their 5's.

The lists of mods were more what others in the tuner community have done to their cars (including the 3), rather than a list Twinturbo was considering for himself. (IMHO)

Judging from the responses to this thread, we are much into appearance and little into performance with our 5's.
Twinturbo, check the threads posted by Venom and those who responded to him for 5's with engine mods.

If funds were unlimited, I would strap on a belt driven supercharger with an FMU and a bigger fuel pump. (cabpatch)

 

[twintrbo]

I did? who did I treat like crap?

Anyway, thanks to everyone else who gave opinions and advice on this matter. Kbrian, thanks for defending me, I thought I was being nice, good to know I'm not the only one.

I only want a little more power, if I want to go fast I have 2 other vehicles to do that in. One has twin turbos(hence the name from other forums), the other is a bike. I know enough about tuning but again I wanted the opinion of others who have done these mods in reality. I surfed the 3 forum because its the same engine, I hope I dont need to explain the relevance of that.

The speed5 is of course the best way to go, but its a loooooooong way to go! A simple turbo kit would be the perfect solution if it were in the budget and the car out of warranty. That being said, I will keep this stuff in mind when I do get around to modding for performance.

 

[thaxman]

As has been said, freeing up weight is probably going to get the best gains, as the CAI/SRI may boost your over 5K rpm hp, but you lose just as much power in the day-to-day rpm range. Unless, of course, you pretty much keep the engine near redline in your daily drive.

And no, twintrbo, I didn't sense any bad attitude from you. If you do find any speed secrets, tho, be sure to share.

 

[twintrbo]

I sure will! One thing I learned about modding though, set your goals and make a plan, then stick to it! Once you get off track, its going to get ugly! I have a few friends who went wacky with their cars. One had over 100K into a mustang, the other probably close to that in a 3000 GT VR-4. Both cars came out amazing but I would rather have a showroom stock viper instead of either.

I will have to take the 5 to the strip and see what stock does before I do anything to it. If the opportunity comes to Dyno, I will do that too.

Garranteed to disapoint. The few times I have spun the tires on my 5 (07' GT wiht a manual), the wheel hop combined with the hammering suspension scares the s*** out of me.

BTW I have been drag racing my Mustang since 1988 on the track. At least I have an outlet for my need for speed.

I am not expecting much, 17.x or something like that, its just for a baseline not for fun lol. I've been racing at Englishtown since 93 myself. Any mods to the 'stang? My first blast in a fast car was an 88 LX notch with some bolt on's. Man was that different than dads 2-tone green, 79 Dodge St. Regis!

 

[Mazda5wannabe]

Front wheel drive, low HP and fairly heavy body (car's, not your's!) will be very disappointing, to say the least. I would expect 18+.

A friend of mine and I used to bracket race a 1969 Olds Vista Cruiser station wagon. This wasn't your everyday grocery getting wagon, though. 454 crate pumped up to 510 ci pushing over 600 HP, tubbed to fit the slicks under the body, 5.13 gear set and passenger car springs fitted to the rear. It's all about weight transfer and launch. We used to be pretty consistent in the mid 11s.

The weight transfer is why the 5 hops so badly. The second you drop the hammer, all the weight goes to the rear of the car and the tires are left scrambling to grab pavement. Let's face it, front wheel drive cars make terrible sports cars!

 

[twintrbo]

You know, the deeper I get into our community, the more I wonder what the common thread of owners are. Seems that utility without excess bulk is the common attraction for these vehicles. Seems most of us are into performance and this thing handles well but is pretty awful on the straights, I know power was my big strike on buying the 5 but I figured if the Lancia we rented in Italy with 60 hp was enough, the 5 should be able to get it done with 153!

Cool wagon BTW, bracket racing is about consistency though, not being the fastest. However, I hate that guy with the POS who runs consistent 17's and wins, its so boring!

you have to judge each vehicle on its own merits. the 5 takes off out of the hole pretty good due to its low 1st gear, so that's fun around town. it can cruise at higher speeds (75-85) easily, and passing is fun because the engine is in its power band at that speed.
it's only 'awful' on the straights if you are considering 0-60 only.
highway cloverleafs are a whole lot of fun in the 5 and you can surprise most anyone w/ it; powerful SUVs that come up close on your bumper when its straight are immediately DROPPED when it gets curvy.
and the utility is great too, because when you've got a home, you WILL be making home depot runs.
