its like a day and night difference,, better pick up and overall feels a lot faster. i know the mat prevents the pedal from going all the way down but i didnt think it made that big of a difference..

Very True. I raced one time at the track with it in and got a 14.6@93 so i opened the hood and had a friend check when i floored it to see if the TB blades fully opened and I had an 1/8 to go so next time around I took out mat and got a 14.2@98

 

Actually its a weight factor. Shedding those extra grams really takes a load off the engine.

 

Does it really feel faster, or does it simply sound a whole lot meaner? The mat could be interfering with your pedal travel preventing you from reaching WOT like Mkos* said. Or, since the mat serves as a sound deadening device your car's engine and exhaust noise is a little bit higher without the mat and it could be that you are interpreting the higher noise level as more power. It's natural for people to associate more noise with more power. Check your pedal travel first.

it sounds the same, it actually feels like its quicker,, maybe GMTech is right about the weight factor. i think i'll write a tech article "Floor Mat Modification"

Even though I have no real tech input I just wanted to add: rofl..lol, that is the funniest thing I've read on this board by far.
So it isn't the fact that we have slow cars, it's the floor mats fault. lol
I'm going to have to send this for my friends to read.

haahaha

 

I just figure that it is a cheap rev limiter.

 

My car feels faster when I fold down the back seats and fasten the seatbelt on the front passenger side.

 

Is that how the ricers came to be? (ex:fartubes on Civics, soundsystems worth more than the vehicle, Mazda rotary engines.....KILL, KILL!! DIE!! DAMN BUZZBOMBERS!!) Just a thought.

Filling the front tires with helium will lighten the front end and move the center of gravity toward the back to give you better traction.

im glad everyone is getting a kick out of this but i was serious.. the car is faster with the mat out,, it has better acceleration,, probably because the gas pedal can now be pushed down further and easier.

 

i feel as though this has boosted performance enough for me to add it to my signature, right after my flux capasitor

this guy told me about the mod

 

Ron,

It must have slipped your mind........

Remember, when you installed the Nitrous activation switch, you put it under the gas pedal. That floormat has been hanging it up.

So, remove floormat, gain 150 HP.

Simple.

Eh, FWIW, I've done the 7/8 throttle bit a few times, and it does not bolster one's sense of ego.......

It's downright humbling. So, now the "wide open throttle" check is done before every re-start where carb/interior/associated modifications were performed.


BOR

 

Hey, i have thought a similar thing actually. my pedal comes all the way down to the floor, and still seems able to go further, regardless of a floor mat or not. so i can see where he is coming from.

perhaps i should go to college and learn "acceleration petal mechanics" and see whats up with it. hehe

 

I was being serious, just in humorous terms.

The gas pedal thing is a definite possibility, almost every racer has been tripped up at least once by throttles that don't open all the way. It's worth a good close look. Other than that, though, it's probably all in your head (your butt?)

------------------

It is really funny but it a very good idea. Check to make sure your pedal is tight, if it is loose then you probably aren't going to get the max out of the engine. It is a very good tip and something everybody should check.

Actually, he's right. If I move my floormats down, it goes faster becasue UI am able to pust the pedal down all the way.

 

Well I dont know about you guys, but my floor mats gauranteed a 10 HP gain. Maybe I was tricked into some kind of gimmick. O well. LOL

yeah well **** on you all cuz my floor mats say "Z-28" on them. that makes it faster. if they didn't say z-28 it would make my car slower. besides chicks dig Z-28 floor mats don't they? oh and the ****** sittin on his 2nd gen TA, i love it! maybe someone else should try to get him on this tech board so he can reveal the rest of his speed secrets such as Auto Zone shift ***** and plastic pedal covers, Wal-Mart tires, garage sale hubcaps, and ACE hardware air filters.

If your floormats say Z-28 and it makes your car faster you should try the "Trans Am" floor mats. They will give you 20 more H.P. over your 10 H.P. Z-28 floormats. Oh and the Chics, they'll also love Trans Am floormats better because they are sleeker,and more aerodynamic. The other day this Awesome Blonde walked up to me when I got into my car and said "Can I see your...(pause)" I though "WOW" and then she said "floormats". See what I mean. hehe, LOL!

Remove the floormats huh?? LOL!! Maybe that'll go well with the 15HP I gained from ripping out my headliner and the 20HP I gained from adding a little plate to my TPI that says "TransAm" on it!! LMAO!!

I like the helium in the tires thing too....tho' I think cement in the tires would give you better traction on the track! ROFLMAO!!

weighs less without the floor mats. gotta be it.

 

Well, when I bought my car the floor mats had already been removed. 4.1 gears were in the back...and I still don't know what other mods it has LOL

Seriously though, I can floor it, and then I can toe the sucker (Sounds kinda kinkey?!) If I actually point my toes into the center of the pedal, I can get an extra 1/8"-1/4" of travel, and oh yeah, it revs much higher, and keeps the wheels spinning in first longer. So there may be some truth to the floor mat removal. Someone should write GM about it (LOL, ROFL) and see if they can't get them to put out a service bulletin about floormats robbing HP...

Perhaps you were stoned at the time?

 

BTW, has anybody tried Fourthgen mats in their Thirdgen? Any mods necessary to make them work? A guy told me even if they don't fit perfect, it's a definite SOTP gain.

Another option I'm considering are big block mats, but I'm not sure they'll work with my intake.

 

well bigblock mats will work only if they say SS on them, otherwise, you will have to run a different farfenater valve. a friend of mine has bigblock SS floormats but his carburator belt was slipping so it negated any gain he might have recieved. also have any of you guys tried rotating your spare tire? if you rotate it exactly 23.5 degrees it is supposed to help you hook up at the track. expect a drop of .000001 seconds in your 60ft time. also for all you IROC guys out there, remove your plastic hood louvers. it lets the engine breathe better by sucking air through the little screw holes in the hood, you have to cut relif holes in the hood insulation though, i heard it is good for about the same gain as adding K&N filters. also (my dad taught me this one) if you need that extra tenth in the 1/4 to beat that pesky mustang in the other lane, try farting real hard. farting displaces air beind you and by pushing it out real hard the force of the gas leaving will help propel your body forward, making you lighter, which reduces you total vehicle weight, which results in faster times. try it, it works, really.

on a more serious note i bought fitted floormats for my IROC from classic industries and it have a relief cutout for the gas pedal so the pedal has room to go to the floor.

Raging, farting in the car is against the rules in most naturally aspirated classes. However farting is allowed in power-adder classes, but you must have a fire extinguishing system on board - can you imagine what would happen if there was a spark? lol...

But seriously, wouldnt it be easier to just shorten either the throttle cable, or the throttle arm on the carb? This way you would not have to move the accelerator as far.

Wait a Friggin' <font size=1>A</font>ss minute guys!!!!!

Any fool should know that our cars are computer controlled, and removing the mats may cause the computer to throw a code!!

Why the HELL do you think GM added all those sensors? for.... <font size=2>s</font>hits and giggles? No, It's for stupid <font size=2>a</font>ss mods like this!!

If you pull your floor mats out of your car, the MAT sensor is definately gonna throw a code sooner or later...and then whatya gonna do when your car leaves you stranded in the middle of nowhere?

And you know what else? Dont go thinking you can just bypass the MAT sensor...because it's not that easy. Unless you have a friend named Matt...Now that might work.

Sheeeesh...I tell ya.

STEVES ZZ5: I hear the same thing about it throwin' a code if you replace the floor mats but I have a perfect solution for getting past that pesky "floor mat" sensor!! (My friend MATT told me about it) You disconnect the "seat pressure" sensor that tells the computer the weight of the driver so it can compensate... then you can disconnect the "floor mat" sensor, install new floor mat, hook back up the "floor mat" sensor, and then hook back up the "seat pressure" sensor!! But you gotta make sure you disconnect that "seat pressure" sensor first or it'll throw everything outta whack and then the only way to fix it is to relocate the ECM to the rear of the car and hook it up to that sparfenator signifier!!
