Horsepower and weight are just parts of the formula. Torque and gearing are what really determine 0 to 60. I am nt saying that mags got the best time. They could be off by as half a second or so. Its widely accepted that a stock ls1 in amags do 5.3 to 5.5 seconds to 60. That means you are besting them by a whole second. At least if you were claiming slicks and not stock tires (I know, you upgraded at 28k)you might have some creadibility. Like I said, if that were posible, we would still buying them today. For gos sake, pro race drivers can only get a 3.9 out of a viper!! If I jumped on some other boards and linked to here, this would be the laughing stock of the internet.

you keep saying that.. but I do go to the track when time permits.. I have all my stats in order and what you are wanting to believe is that our cars are capable of accelerating 25mph in less than 4 seconds with a shift thrown in there.. as I stated before, if you would like to think my car just can whip up 7+miles per second increase in speed then fine.. but maybe you ought to consider the outside forces as well.. wind resistance??! Does it stay a constant or does it increase with speed?
Think about it..

as for people laughing.. I dont care what simple minds wish to laugh about.. Ill meet them at the track and run there..

I will also add that although I had a 2.1 short time there was no spin whatsoever.. None.. and I dropped the clutch at 2700... the following run I dropped at 3000 and the clutch overheated.. I ended up going from first to second (where it didnt catch and the rpms stayed at 6K) then to third. I still ran a 13.9 @ 99 on that run while missing an entire gear (second)..

My next run at the track will have me dropping at 3200 to see if I can bag my 12.9's stock.

Ill do this to alone to address the reason why the Fbod is no longer available..

when was the last time you saw a commercail for a camaro?
The trans am had 1 commercial where the car takes off from a light and blows up the light and whatnot...

but from 1995-2002 there were no commercials for camaros..

I can recall commercials for mustangs for almost every year..

Now I wonder why they out sold us.. all the fbods combined couldnt match up to the sales of the mustangs.. thats why there are no more..

Even to 60 you still have t shift from 1 st to second. You start to notice pattens with cars. 5 sec to 60 cars usually run 13's in the 1/4. High 4 second cars usually run high 12's. Low 4 second cars run low 12's to high 11's. Now with slicks, I have no doubt you could do high 4 seconds to 60, you might even convince me of a 4.4. On stock tires I just cannot make my head trust it. Stock vettes with the ls1 with less weight usually run 4.7 or 4.8 to 60 with good drivers, better tires, stiffer chasis and all the other goodies. Low 4's are the z06 vette territiory.

But you have no trouble believing that you car car can pick up an average of 14+mph per second in it's sprint to 60mph? And now after 60mph, it's picking up at less than half that rate?

You're even saying it yourself, bascially: acceleration slows down as speeds increase (that goes for pretty much any car, with the exception of some supercars)...so how can your 60-85mph be almost identical to your 85-110mph?

Lets play with the math then to show our work ok?
This is the 0-60 section:
I say that its in the 4.2-4.6 second range.. but others wish to belive it has to and can never be anthing less than 5 seconds (with some people thinking that it has to be 5.1-5.3 on average)..
60 / 4.4 = 13.636 mile per hour increase

60 / 5.2 = 11.538 mile per hour increase


This is the 60-85 section:
If 4.4 then:
8.601 - 4.4 = 4.2
This is the time it takes to get to 85 mph from 60 with 1 shift..
25.25 / 4.2=6.011 miles per second increase

If 5.2 then:
8.601 - 5.2 = 3.401
This would be the "accepted" norm for a car to get to 85mph from 60 with 1 shift
25.25 / 3.401 = 7.424 miles per second increase

This is the 1/8th to 1/4 mile section:
13.174(1/4 mile time)-8.601(1/8 mile time)=4.573 seconds
108mph(1/4 mile speed)-85.25mph(1/8 mile speed)=22.75mph
22.75/4.573=4.974 miles per second gained on average..
5 mps increase is very believeable compared to 8..


Lets not forget the gearing here as well..
M6 rear gear being a 3.42
1st Gear Ratio 2.66:1
2nd Gear Ratio 1.78:1
3rd Gear Ratio 1.30:1
4th Gear Ratio 1.00:1

So with the size of the first gear and the size of the gears from 2-4 doesnt it seem believeable..

Ohh well..

I feel like I'm in physics class doing a pointless problem like calculating the mass of a ball point pen on jupiter. Who gives a rat's a@@.

I think 0-60 times are completey irrelevant because there is no way the average person can measure them, unlike 1/4 mile times. This thread is so lame

96SFLZ

Ok, you can believe whatever you want...which is fine with me, I just don't agree with you (nothing more, nothing less). Fact is though, you don't know what your 0-60 is...but then, neither do I.

96ta(nick)

hmm calculator shows my 0-60 as a 3.8 with a 2.1 60'

falchulk

96ta, better get out there and start kicking some viper and Fort GT a$$!!

96ta(nick)

better be at the track because on the street all i do is spin..

birdmanz28

that guy is such full of sh*t .. theres no way.. and I think we all know it .. except for him.. that your not runnin that quick in a stock ls1... If your engine was that strong which its not.. you wouldn't be able to hook up that good to pull that kind of 0-60 and 1/4..
A 12.8 - 12.9 isn't possible in a stock ls1 z28 and I would love to see this 13.1 you speak of.

Slappy3243

Actually, he is a well respected member on this board. You sound like a fool in judging him while you have only been here a month. Although that 0-60 seems a bit low, I don't think it is impossible.

falchulk

12.8 or 12.9 is easily possible stock. I have seen it done....with slicks. What makes me personally doubt it is that he claims it was completely stock including the tires.

StormSigma

I agree. I highly doubt his numbers as well.

After all, we can sit here and crunch numbers all day, but they won't mean jack in the real world.

I mean, hell, I have a friend who's a mathematics major, shooting for his master's degree that can show you, ON PAPER(several sheets of it) how he can get 1 + 1 to equal 3.

And we all know that 1 + 1 does not equal three, just like we know that bone-stock f-bodies aren't running a low four second 0/60 on street tires.


But hey man, thanks for the math lesson!
