What is the fastest 1/8 mile, 1/4 mile 68, 69,70 Charger in here?

[Harper]

Inflating the front tires beyond their max is dangerous and the dumebst thing ive ever heard of. I would never reccomend that. All it would potentially do is change the reaction time by a few ten thousandths

maybe so but there are a lot of ppl who believe in doing this...it helps
if your bracket racing i can see where it would not matter, Kentucky Bowling Green, Miss Gulf Port, hattisburg, Georgia Reynolds
never had an issue, never was told to lower my pressure...

[70sixpkrt]

yea but that all depends on a lot of factors, temp out, tire pressure, what RPM he's leaving at etc. i figured 12.7 at worst. i guess 12.4 may would be possible. But that would be in an ideal situation

for instance what FRONT tire pressure were you running 70sixpkrt? inflate those suckers up to 60 or more and see what happens...same as pushing a wheel barrow with a flat tire vs full inflated.

32 psi on all 4 BFG. I'm no racer but just wanted a car that would run mid 12's. It's a 4 speed car and leaving the line at idle.

[Harper]

70sixpkrt

that is an absolute clean car. If that run was on regular BFG's that was excellent.

Inflating the front tires beyond their max is dangerous and the dumebst thing ive ever heard of.

I guess you have never heard of the following:

People that have sex with prostitutes without wearing a rubber.
People that use heroin and share needles.
People that ride motorcycles at 100 mph between cars in traffic while doing so without a helmet.
People that piss into the wind.
Letting thousands of Syrian immigrants into the country.
Government paying thugs to stay out of gangs.
Naked snow skiing.
The polar bear club.
Running with the bulls in Spain.
Messing with Sasquach.

Not following... if i run 93 octane, and dump c12 in the tank, it will make no difference, despite popular myths. And on top of that, it smells different, so if its a tagged and insured street class, you will get caught as soon as you start the car. So the fuels in question must not be typical race fuels, thus why i am inquiring.

Joe is correct.  Not to hijack the thread, but a fuel's octane rating can be thought of as "how SLOW it burns"  In other words, if you don't have the squeeze that needs 108 octane, you'll slow down using it.

Exactly.   Octane doesn't add power.    A really hot engine that requires high octane should have a lot of power, but not from the octane.

  yes, ive heard of all of those things. I would just like to see some proof that putting 60 pounds of air in a 35 pound max pressure tire is a good thing, by actual scientific fact, not "because thats what the guys i ran with do"

[Aussiemadonmopars]

Here a video on the Aussie Charger.

Cool story worth a watch

https://youtu.be/-n7rtkX7nl4

I saw it a few times on the streets of Perth here. If the cops ever saw it they would of thrown the book at him I'm sure. Like he says in the video - we have to take our cars to the US in order not to not be noticed and enjoy the freedom. We live in a police state here where they clamp down massively on Hoons or Hoonish behavior. If it looks like it's doing 100 mph standing still at a traffic light then guaranteed you'll get pulled over.

[440]

Same situation here in SA which is known as the nanny state, luckily we are moving to Victoria soon. My Charger was road registered in NSW but I couldn't register it here. Some of the hoon laws are also BS in my opinion, as well as having to get things like disk brake conversions engineered to be legal and ...... don't get me started, lol.

you can run 25 psi in your tires if you like, drag a boat anchor or whatever. I will use every advantage i come across. thats just like Nitrous is NOT for everyone. Some ppl like NA, some turbos and some superchargers. If we all did the same thing this old world would be quite boring.

Overinflating your tires has nothing to do with building a nitrous or turbo motor. I still ask to see the evidence where overinflating them made your car faster? At most it will have a marginal effect on your reaction time because raising or lowering the pressure a few psi changes the rollout rate of the tire. Now this is only true of a drag style or old school bias tire. Your bfg radial ta will have no difference because its a radial. So please educate me on how you are correct.

like i said you can do what you want to do. It made my car faster and I will do it again. period

it has Nothing to do with reaction time nor roll out...its the entire length of the track that makes the difference.
so run lower pressure in your rear tires to, see what that does. other than traction it does matter how wide your tire patch is correct? i mean why run a 15 wide tire on the rear if you can get away with a 10 or 10.5 inch wide tire and get the traction you want? it slows you down, that is a fact. There is a happy medium on rear tire inflation vs over inflation as well as the front. If you don't believe it that's your prerogative.

Now this is only true of a drag style or old school bias tire. Your bfg radial ta will have no difference because its a radial. So please educate me on how you are correct.

i ran radial front tires on my,s street car, my early bracket car as well as on my purpose built race car (skinnys on my race car).
as a NOTE i didn't just show up on street night and make a all out blind wild pass and not be able to repeat it,
I documented which lane i ran it, whether it spun or hooked, which rear tire pressure, what the outside temp was, barometric pressure was, humidity, my engine temp, my reaction times, my mph, my 60 ft, the time, and even what RPM i left at and where i shifted at, I can promise you I did test, i documented it and it worked for me. If you choose to believe something else or do something different, thats ok. No harm no foul. I not just talking out my ass like you seem to insinuate. 
this is NOT my first rodeo, maybe you believe your answer to be correct, well so do I. lets let it go at that.

Thanks, your words speak volumes for why noone should ever follow that advice.

Not to hijack the thread, but a fuel's octane rating can be thought of as "how SLOW it burns"  In other words, if you don't have the squeeze that needs 108 octane, you'll slow down using it.

All gasolines, pump or race fuel have very similar burn rates. 

Higher octane is higher resistance to auto ignition and detonation, not slower burning. Still there is some variance and some of the fastest burning fuels are race fuel (would be a problem on nearly 20k rpm F1 cars).

That being said, agreed that you can realize a power loss in a mild combination that does not require race fuel as some race fuel has a lower energy value (btu/lb) than pump gas.

whatever the point of the thread was to see how fast ppl who time their cars have run not to have a pissing match...

so how fast you ever been at the track (in your own car) coondog? just curious...

[funknut]

Over-inflating fronts is old news.  Everybody knows all the really fast guys run a 1/2 fill on the front tires.  Increases sidewall strength and keeps the front end down.

156 mph in the 1/4.

:2thumbs:Nice.

[c00nhunterjoe]

It runs ok.

[Harper]

  what ET?

[c00nhunterjoe]

Nhra supergas. Runs a 9.90 every time.

[INTMD8]

Nhra supergas. Runs a 9.90 every time.

I would find frustration in holding back a mid 8 second car to run 9.90. 

[c00nhunterjoe]

Its an artform to do it consistantly. Car should run low 8s all out. During that 9.90 pass, about 3 seconds of it is at idle going down the track. Some guys in the class are in the 180mph range.....

I'm sure the consistency would be tough, I would just want to let it eat

Or at least move it to an 8.90 index, sounds like everyone has enough power 

[c00nhunterjoe]

Supercomp is 8.90 index. Most of them are dragsters. 180+ in those guys.
