How To Restore Lost Power...No BS

Ok..now we all have had problems with starting torque and horse power when our cars get old right...Read my story!!!!!


I bought a 97 ga gt 3100 18 mnths ago.. I noticed that it did 0-60 in 10seconds ...1/4 mile in 16.5 @81mph. Not too bad.. But for some reason i could not squeel the tires. I tries replacing the coils, air flow, intake manifolds, exhaust manifolds, upgraded to 2.5" exhaust. no cat, no mufflers, etc. I had it dynoed at 125fpt and 150hp...and 0-60 in 10sec and 1/4mile in 16.2 at 82mph. Then like 1 months ago just for the heck of it i got a new mass air flow sensor..one of those good quality ones..it costed about 300 bucks. I put it on and damn....!!!!!!!
0-60 in 8 secs, 1/4 mile in 15.2. 175fpt and 185hp. I can now pull the ebrake and sit there and do smoke shows. I have learnt that the mass air flow sensors wear out and become less effective over time. they don't give a signal to the computer but just start to work less efficiently and give poor throttle response. it went up 50fpt and 35 hp just for a damn sensor.

THIS IS NO LIE....IF YOU WANT PROOF I LIVE IN WINNIPEG, MB I CAN LEND YOU MY NEW MAF SENSOR AND TRY IT OUT YOURSELF. IT IS WORTH MILLIONS TO ME NOW. I NOW LOVE MY CAR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!

No way a MAF got you that kinda of power.

The cam I installed into the Trans Am didn't make that much power.

Another reason I call BS, 50 HP is not NEAR enough HP to knock off a full second in the quarter mile.

Your a dumbass.
The problem was that my old sensor was causing my air/fuel ratio to be so messed up that my engine didn't work properly. I have seen a 99 grand am with a turbo putting out 232hp pull a 1/4mile in 13.8sec. Don't waste my time with your 50hp can't take off a whole second nonesense!!! LOL

Not much track time junior??

Rough estimates, but they are pretty close.
10HP = 0.1 second off
100 pounds lost = 0.1 seconds off.

Call me a dumbass all you want. I know what power it takes to run the 1/4. 50HP isn't enough to knock off 1 FULL second. Try again.

look idiot. honda civic stock 90hp 1/4 mile time 16.8sec. add a supercharger etc bring up to 140hp you could be running the 1/4 mile in low 15's high 14's. Only if you are dealing with like 500hp to begin with will you only see 1/10sec for 10hp gain but not in lower numbers. you must be just some kid or something. the 350z does the 1/4 mile in 14.0secwith 275hp the 04 grand am does it in 15.9sec with 175hp...that's 100hp for 1.9sec or 55 hp for 1 sec. and the 350z weighs more too. Burnt

Oh ya...I want everyone to see your dumb theory!!! LOL

Burnt

Nope.

You are comparing a Nissan and a Grand Am. And you call me the idiot. Two TOTALLY different cars. Traction, weight, weight transfer, driver, etc.... all play a role on times. Generally speaking, 50 HP will net you 0.5 off your 1/4 times, unless you also add suspension, or stickier tires.

And I am no kid. I am 25, and have been racing my Trans Am for a couple years now. I own a 2001 Grand Am GT as my daily driver.

These power gains you claim to have, since you gave us numbers, you should also have timeslips and dynographs. You wanna 'burn' me, prove me wrong. Until you do, you are making yourself look stupid.
Good night.

your crazy... do you believe a grand am with 233 hp can run the 1/4mile in 13.8seconds!!!!

13.8sec 1/4 mile 233hp...
stock it has 175hp 1/4 mile 15.9sec
that's 2.1 seconds for 53hp!!
And 25 is a kid. I am 47. Unless you were alive for the birth of the gto you are a kid.

Reply to that buddy!

Stock rated at the FLYWHEEL on the Grand Am is 175. Not to the wheels. Those numbers you gave are DYNO PROVEN.

In other words, your numbers are very skewed.

Plus, I am sure there are other variables into play as well. I am sure stickier tires were probably used, different gears, suspension changed. Plus, with the addition of the turbo, the powerband completely changed. I never said it wasn't possible, just as a rule of thumb 10HP = 0.1 seconds.

Oh, that is ONE UGLY ASS Grand Am as well.


Now, lets get this back on track. Prove to me that you gained this much horse, and ran those times. Either post, or stop spilling BS.



Oh, and by the way. Are you sure this exact Grand Am ran 15.9??? Or are you mag racing??

Anyways, I am out. Seeing as how I am a kid and all, it is past my bedtime.

I like you source for this information, modracer.com. Do you believe everything you read on the internet? Internet racers are all talk; show me some dyno sheets and time slips. That would prove your claim to be true. According to you my Subaru Outback is a 14 second car

And 25 is a kid. I am 47. Unless you were alive for the birth of the gto you are a kid.
I was born in 1972, I'm not a kid, but I do remember the birth of the K-car

185hp out of a grand am with headers, 2.5" exhaust, new coil packs, jet chip, pp intake manifolds, performance plugs and wires. running a 15.2sec 1/4mile. you guys need some serious help if you think that's impossible. I don't get it I just was just excited about this and wanted to tell eveeyone but you say it's BS. What do you think a grand am with those mods should run in the 1/4 mile. huh?? you tell me that!!

oh ya it was 15.2sec @ 89mph... That sensor is the most vital sesor on the car(within reason) it's almost like running your car with 5 spark plugs and then with all 6. If something that important isn't working properly it will mess everything up...you know what i got an idea. unplug yours and run the 1/4 mile then post your time. LOL

You can run a car with a bad sensor without too much affect; yes it will turn on a dash light however nobody is going to gain seconds off 1/4 mile times by putting in a new sensor. An automotive sensor is just that a sensor. It will tell you about a problem with the engine, but if a sensor itself fails; this only will give the driver a false reading about the condition of the engine.

Your the one making the claim about 1/4 mile times, I choose not to drag race my station wagon. Its a good car for racing down to the supermarket, nothing more nothing less.

Actually the mass air flow sensor determines how much air is going into the engine and how much gas to give the engine accordingly. It DOES make a huge difference. Just try it. there is like a hundred places that sell them. they claim on newer vehicles you get from 11-33 hp which is over what i would agree with. but with older vehicles it can make a huge difference. Just Try it

Or don't I really don't care at this point. I just thought I would give some FREE adviced but assholes out there just wanna fight. so fuck off

Humor me.......

Send me a link to this MAF. The one you got, or a pic might even work. At this point, you aren't backing up your claim to the power you gained. Because I think that you can't.

I don't wanna fight, I am not that way. But I do call BS when I see it.

Not wanting to get into the middle of a flame war,

But I can see it.... I've dropped a second off of my strip car just by jetting the carb correctly... On these cars the computer relies on the MAF to tell it how much air is getting in... so it can adjust the fuel mixture and timing(that's how computer chips make a difference). If the original MAF was screwed up & not working properly.. then a new one could make a big difference. More than just upgrading a properly functioning MAF.

Now.... I agree that the dyno numbers are fishy & would also like to see a before & after dyno sheet. Does anybody know what a stock 3.1GA will run in the 1/4??? I have a feeling his "before" times are slower than stock.

But I can't discount the time drop just because of it. A rare occurrance that will probably only work situations where there is a seroiusly F'd up MAF, but possible.

Just for example... say a stock GA runs 15.0 in the 1/4... MAF goes bad causing it to run a 16.0.... once you replace the MAF, you'll be running back to the stock number again. One second is almost inpossible to tell by "feeling" so he probably never felt the car get slower, then ran it with the bad MAF... assumes that's the correct stock time... and boom.. here we are.


Just my :2cents:

ok just so everyone know i have time slips from wen i raced out the track with my 2001 3.4 grand am with a flowmaster exhaust and K and N intake and i ran a 15.4 so if that helps anyone base anything on this whole argument lemme no and on more thing winnipegman the older stlye grand ams r shit there not fast AT ALL so i dont were ur gettin ur times from and i alsot agree wit mr luos u cant knock off a whole second like ur sayin it aint gonna happen
