Thank you mPoRtSsUcK! That's more of what I was expecting to hear.

considering that my times are actual track times its not bench racing as much as statistical analysis.

Psychocabbage, what would you say my 0-60 times are with your calculator? 12.57 @111mph 1.86 60' 3800 lbs approximately.

psychocabbage

the calculators are there for you to try..

I weigh my car after every run.. each of my timeslips will have the time of day, date, who I raced against, and the weight of the car.

Here's how you calcualate 0-60. Find a cop with a stopwatch, tell him to time you from when you take off till his radar gun reads 60MPH, and then you can do the same thing for 70,80,90,100, 110,120, 130

Seriously, I think the car magazines use a radar gun to calculate 0-60 times.

psychocabbage

car magazines use whats termed a "5th wheel".

It attaches to the rear of the car and will calculate this info.

They have recently started using more expensive accelerometers to record more data but what many people dont often account for is weather, elevation, driver and state of the car.. New cars rarely have the same performance once they are broken in.. LS1's in particular must be broken in to truely see their full potential.. way too often the car is modded before it is even broken in..

Using that calculator my old 95Z's 8.48 @ 85 MPH 1/8 time adds up to a 4.23 0-60 time. Not too shabby!

psychocabbage

kewl.. now for sake of arguement.. would you say that your car felt faster going to 60 than it did going to 80 or even 100?

My LT1 was great to the 1/8th mile.. then dropped off as LS1s would then start to walk on me..

My LS1 is linear and seamlessly pulls but it sill gets to 60 faster than it does 60-100.. or even 60-85..

MikeyG

Well, considering it only pulled 105.5 in the 1/4 after 85 in the 1/8, I'd say the top end was terrible! Pretty much any other 4.2 0-60 car out there would hand me my *** if it was 0-120!

My current 98 Z M6 only pulls 82.XX in the 1/8 but 106+ in the 1/4.

Gotta love the LS1!

Another factor to remeber when reading magazine numbers is that the cars they get have been ragged out by other journalists, also hurting acceleration times. These are cars that might have been ragged on with 300 miles on the clock, definetly not good for the engine.

psychocabbage

Ill finish off by stating that not only must the car accellerate about 8mph per sec but somewhere I have to shift right after 60!..

falchulk

There is no way that a stock fbody can do 0 to 60 that fast. Since you are fond of calculators, have you plugged in your gearing/horse power to one to see what that type projects? I will tell you right now, if anyone but fbody guys read this they would crack up laughing. If this were possible, don't you think there woul be more guys saying they can do this? A car with that type of performance for the price would not have gone out of production!

psychocabbage

not of gone out of production? hmm.. lemme see.. 427 Shelby Cobra comes to mind.. it didnt sell.. it went out of production..

so lets get this perfectly straight because somewhere you find it hard to believe..

you are stating that since magazines everywhere state that the stock fbods are only capable of 5 sec 0-60 times then I too must be in there.. so saying that and knowing my track times in the 1/8th mile we are going to feel fully comfortable with an fbod accellerating from 60mph-85.25mph in 3.6 sec with a shift in there..? (thats 8.6 @ 85.25mph) So that means that we can also state that the car somehow gains 7.01 miles per second average after 60...

So what sounds more believeable to you? 4.4 0-60 would leave me 4.2 seconds to get a shift in and accelerate 6.01 miles per second which sounds much more reasonable than 7 or even 8... with a shift mind you!

Now for more stats.. heheh this is too fun.. now keep in mind I am old and bored so I love over explaining this stuff to people..


A 1/4 mile calculator based off weight and hp

Aother based off weight and flywheel hp

this calculates flywheel and rear wheel hp.. pretty accurate if you ask me

Now if you happen to know of a calculator that makes you feel all warm and fuzzy post it up..

Till then know that my car is still bone stock save for the following:
*Oil has been changed like 4 times.. maybe 5.. 38k+ miles now..
*Front disc brake rotors changed yesterday 4/26/04 and new pads as well..
*Air filter replaced with AC Delco replacement air filter at 38K+ miles 04/02/04 for my birthday
*Gas .. added weekly!
*Tires.. changed the stock GSCs after driving 28K miles on them for Yokohama AVS ES100's.. Street tire with similar ratings..

Now do you really think I dont know what I am talking about?

Geesh...

Shelby Cobra was a race car. The only reason they made street cars was to meet the race rules that said there must be a production variant.
