This is why H rated tires suck!

WTF is drag limited?!

F=ma Force = mass * acceleration.

Alright.. so what is the force in the car... 3 major things...

1) The rolling resistance of the tire against the ground. Due to the deformation of the tire, the way air flows over it, and the adhesion to the ground from various factors the tire requires a certain amount of force to be rolled along the ground. Some tires are more efficient than others because of structure... and some more efficient than others due to tread pattern and silica compound.

2) Mechanical loss. All those bearings and rotating parts experience friction and viscous loss etc that results in an overall force that needs to be overcome... some of you call it driveline loss or drivetrain loss or transmission loss... but that isn't completely accurate as you get other losses from wheel bearings, seal mating friction etc.. and that will change with speed/rpm's.

3) air drag/turbulence force. The faster the car goes the more rapidly it has to push air out of the way. This also generates a greater and greater pressure differential between the front and rear of the car... this in turn determines along with the mechanical shape of the car how much "drag loss" due to air you have... the faster you go the more you have... the more turbulent the air flow is the more you have as well...

So add those 3 up and you get an amount of force acting on preventing the car from going faster... now the motor can only put out so much force (torque when divided by the length of the wheel diamter is the amount of static force being applied at the ground to move the car... ) So anyway.. when the forces acting on the car match or exceed the force the motor is generating at the wheels the car stop accelerating. Your drag numbers of reached you engine output numbers and you can now no longer accelerate... and if you shift up in gears, your torque multiplier drops and then torque at the wheels drops... and suddenly the drag forces are higher than the wheel forces and the car starts slowing down...

So now if his car aerodynamically is poorer (windows down just the wrong amount etc) and his tires are extra crappy and the tread is of a poor design the you'll have even more losses for rolling resistance... pair that with everything else and suddenly you have a P5 that can only do 98 mph when another P5 may pull off 110 or 120.

Drag limited speed... any time your car can't go faster because of forces rather than an electronic limiter or simply running out of gearing and revs.

Sweeet wright up TurF!!!

i am aware and can confim everything you have stated... what i was unawre is that if would or could have that much effect.... im still slightly skeptical that that is the root cause especialy since the kind of forces your desribing affect every p5 equaly stock or close to it... and hes way of the bar... way off... but your theroy cleans up the picturer alot... did anyone notice this video may jsut be a dig a t MP's trying to pok fun.. or is this kid really that "hung up " on his tires?

didnt see him saying anything after the post....

 

[jbiird317]

ha jeez all this explanation just to tell the kid to put his windows up? my 2000ES when it was stock would hit 115 and do the same thing as his, so if ur only getting to mid 90s there probly is something else going on there than just too much drag

had my protege cruising at 105 for a short burst last week and had no trouble getting there........

lol lmao

 

[shane02pro5]

How does the car idle, accellerate, pinging from bad gas? Any Cels? Clogged cat or nasty dirty air filter? Check the simple things first.

How can we get to the bottom of Page 2 before someone mentions that this guy is nothing more than a troll? "I am a newbie with lots to offer... " Give me a friggin' break. No human being is that stupid.

DON'T FEED THE TROLLS!

EDIT: (to be uptight and politically correct...)

Please reproduce this featured high speed action movie without your super cool choice of Pop music. This way, some of us people here can listen to your engine or exhaust to see if we can tell what is stopping your vehicle from achieving 100mph. (Which is approx 160km/h. I'm saying this to not offend other Canadian folks by myself by using american only units of speed.)

(braindead)

But in all seriousness it might be a part you added that you think is doing good, (ex: exhaust if it's cheap) which is actually preventing you from going that fast. It has absolutely nothing to do with the tires.

I saw your original post and this is the funniest thing I have ever seen.

You should post the original and title it how not to be PC and this one is how to be PC like a before and after.

As a Vendor I don't find it funny at all and it has nothing to do with being PC or uptight... the fact is that BS is what leads half the the threads we have into flame wars and useless crap information. Additionally, if the guy seriously didn't know what is/was going on and is a new member you have now managed on his 4th post ever to make him shy away from this forum because it is filled with people acting like asshats as far as he knows. That hurts me and the other vendors on here because that is one more potential sale not here because you think it is funny. It isn't intelligent, it isn't helpful, and there are far better ways to state things. If people thought their statements through once in a while we wouldn't have all the BS fights and we'd have more useful information and more friendly discussions in general. Off the cuff rants and backhanded remarks do nothing for the community and show an overall lack of intelligence and maturity.

EDIT: For those who want to rip other members for no reason /EDIT Type something worthwhile... or go play with your carbon fiber sticker hoodpins for a while to get your latest bit of "NOS" filled enjoyment.

 

[evilmonkeyMSP]

(rofl) (lol2)

So type something worthwhile... or go play with your carbon fiber sticker hoodpins .

 

[jeremyfl]

So your statement to me is a logical and well thought out huh???

As an Authorized Vendor I would have expected more from you.

You are talking about loosing potential customers due to people being asshats (as you put it) and there you are being exactly what you said is wrong with the forums. Yeah real intelligent.

And you never know maybe I was going to buy those carbon fiber sticker hoodpins from you, but you will never know.....LOL

Here is another thing if the post was that upsetting then a mod or an admin should have told him something not and Authorized Vendor.....

 

[evilmonkeyMSP]

just because a mod doesnt step in doesnt mean you should be ignorant...

not directed towards you jeremy

 

[Protege52003]

with or without the kayak on top?

not that time......have gotten probably close to 90 with them on top......they are not going anywhere when properly strapped down......

In what way did I fail in any expectation that you should have of an authorized vendor? My point was from the start and very clear that you were condoning the kind of mentality and activity on this forum that causes so many problem. How in any way was his statement about the music in the video productive, positive, or useful? So you want to encourage people to at any time make any kind of obscene statement they so choose because they differ in opinion on someone's taste? In this case in music? My statement was very clear from the beginning that my asking him to edit his statement had nothing to do with being PC or being Uptight but rather showing some respect and patience for a newer member. Using slurs to describe someone's video post is nothing but degrading to that member and any point or question that they had. While my word choice of "asshat" may be somewhat stronger than the other option of "jerk" it was intended solely to provide some emphasis to the fact that the behavior you were condoning was more than the average internet jerk routine.

How was I in any way being a jerk? I never once directed my statements directly toward either of you... my statement if you read it closely (and think about it.. because it was well though out) stated that it would be easy for him to construe that the forum was filled with jerks/asses/whatever you choose because his single post was met with nothing more than a series of flames about his choice in soundtrack and his possible lack of knowledge on a point of technicality in tire construction. So if you post up an image asking a tech question that may seem obvious to the rest of us, but not to you and you use a pink box to indicate what you want I should refer to your post with slander about the pink box rather than constructively pursue your question?

And my last statement regarding the CF hoodpins was purely for levity (which orphman got) because CF and NOS are the typical run of the mill jokes used in the car communities to say that something shouldn't be taken too seriously. I did not direct it toward you personally or anyone else... and wouldn't intend to do so.

The mentality that mods are the only ones who can regulate or indicate bad form on the forums is similar to a mentality that because you know your buddy is out ripping off rims or smashing windows on the cars it isn't your responsibility to say anything and you'll just have to wait until the cops step in instead.

My statements were intended toward a mature and constructive point, condoning statements like was made earlier does no one any good. If you do not take those statements at that level of maturity and understanding then I guess you could take them to be less than what they were.

I care more about my reputation as someone there to help and to answer questions regardless of how "stupid" they may appear to someone than whether or not I will cater whim and fancy to someone looking to be a jerk. If I lose a sale because I'm willing to stand up for a mentality and a thought process that helps better the forums and encourages new members to ask questions regardless of how simple the answer may be then so be it as I'd rather conduct my business honorably than by degrading anyone whether they may buy form me or not.

If you can't see and understand that in my comments than so be it. I don't make money (have yet to put a dime in my pocket), and I started the company purely because I was tired of crappy vendors who wouldn't answer questions, didn't follow up on orders, and who marked up products unnecessarily. I will stay true to those reasons for this business and I will continue to defend the right of anyone to ask questions regardless of how silly or incorrect or how valid or technical they might be and their right to be able to ask them without fear of being ridiculed by the immature and ignorant.

 

[TurfBurn]

not that time......have gotten probably close to 90 with them on top......they are not going anywhere when properly strapped down......

i was actually half curious how fast you could go with them on top before you topped out... for example if you can do 122 before you top out with them on... and then can do 110 only with them... than that is exact proof and theory of what I was explaining earlier

 

[gt3_dk]

I saw your original post and this is the funniest thing I have ever seen.

Haha whatever I forgot what I wrote... I swear too much...

So type something worthwhile... or go play with your carbon fiber sticker hoodpins .

LMAO!!! That exists??? That's gotta be the top rice toy of the year. I think I'll also put one on my school locker because I think it's gonna make it close harder and people won't be able to steal my books... (jerkit) And I'll also wrap a V-Teck sticker around it to reinforce my high end power because V-Teck is faster and better so the sticker is gonna make my new lock better, and cooler to look at.... (blah)

Whas this? All I get is that the dude on the dude is saying somthing like:

"(u) don't f$%k free? I'm sorry...)"

I dunno why that came up in my head, neither am I a lip reading expert.. but umm yeah thats what I saw..
