I was just curious, that if occationally (maybe a street race) i totally "gun it" or pin the gas peddle. Is it like harmfull to the transmission. Is that hurting my engine. Everytime I kinda floor it off a light i back off, because i feel im hurting my max. Is this bad. I have an auto 95 Max.
Thanx

 

Yes and yes.

 

Yep its bad.

As medicsonic about being floored @ 140 for over 10 mins straight.

 

Put the pedal to the metal and let the car do it's thing. It's fun!

 

 

but don't forget that it's also bad not to drive a fast and furiously once in a while. driving like a 'little old lady' actually builds up carbon deposits around the plugs and invariably on the valves etc... so it's actually good to get the revs up and burn them off once in a while. so it's a balance i guess...

 

How is this bad? besides burning a lot of fuel and tires.

 

That is a very good point. I usually drive (90%) locally and i do sometimes take the highway for a longer trip to open up the car and blow any carbon out.

 

This is pure conjecture. There is no reason that driving slow would increase deposits in the engine. Just think about it. As long as the plugs get up tto their proper operating temp (which they do in mere seconds) they clean themselves. And as far as carbon on the valves, I dont know how driving slower would increase that.

Please explain.

 

what happened?

 

It may be bad for your car, but it sure feels good!

 

If they clean themselves, then we would never have to change them, right? But they do get dirty, and heating the plugs over their normal temperature during quick bursts prolongs built up deposits.

 

maybe this is just me, but it seems like if you floor it, its not as fast as if you almost all the way floor it at first then go to the floor..

 

True.

 

Whenever I try to floor it, it goes nowhere. Takes a second to kick in. Automatic's are SLOW.

 

We dont have to change plugs because they get dirty. (Or we shouldnt be) We change them because they wear out. Each time the plug fires a tiny bit of each electrode gets vaporized. Over time, this wears the electrodes down and widens the gap. Platinum plugs last longer because they dont burn away as quickly.

I took the 90000 mile old non-platinum plugs out of my fiance's Nissan truck and they werent dirty at all. But, they were severely eroded.


Tell me again how dirving slow causes carbon to build up on the valves...

 

I forget what they call it, but a driving school I went to explained what you had said. According to them, if you floor it, the mixture becomes overly rich because the engine is shooting the fuel faster than sucking air, and it takes a few seconds for the air to totally catch up. I agree with you that it doesn't seem as fast when you floor it compared to part throttle at first. Maybe what they said is true (the school is National Academy of Professional Drivers-Tactical Police Driving).

 

An engine revolves around the constraints of basic physics. Engines operate best and most efficietly at normal temperatures. Temporary higher heat and higher flow of liquids burns or pressures away deposits. Think of an oven that needs to be cleaned or a sink faucet that is clogged.

Gas contains all kinds of junk, some cleansers at the higher end stations and some 'fillers' at lower end stations. however, in this not perfect world, the gas does not burn cleanly and thus, leaves deposits in your injectors and consequntly, those loose depos**** end up near and around your plugs/valves. Pinning the gas peddle once in a while will free up and lossen those deposits in your injectors (like turing you sink faucet on high) and the extra heat in the combustion chamber will burn and expell those contaminents through the exhaust. Driving slow ALL the time using regularor inferior gas these days CAN clog your injectors, and get unburned deposits shot into your comb. chamber.

Plus, it's fun.
