Second time at the track - Let me know what you think

[Seb Cyclefer]

I still have a bad 60' but it looks like that I gained some power after installing a new timing chain, new ignition module, cables, iridium ngk plugs and replacing a bad coil.

To compare, let start with my first time at the track last year: 2004-09-25 in the afternoon. Beautiful sunny day 27 celcius degree (84F) and humidity: 65%
Car odometer: 188000 km

R/T 0.306
60' 2.438
330' 6.801
660' 10.412 @ 68.371
990' 13.480
1/4 16.026 @ 88.972


Second time at the track: 2005-10-28 in the night. No wind, temp: 10 celcius degree (50F) and humidity: 74%
Car odometer: 225000 km

Here's two of my best time. The first is my best E/T of the night and the other, my best speed trap of the night.

BEST E/T
R/T 0.034
60' 2.455
1/8 10.160
1/4 15.535 @ 95.992

BEST MPH:
R/T 0.124
60' 2.556
1/8 10.222
1/4 15.582 @ 96.538

I know that I must improve my 60' but with a speed trap of 96.538 mph and a good 60', what time could I expect to have ? I the high 14 sec ?

Is 96.538 mph good for a N/A 3.8L ? I was happy of that increase of 7.556 mph a year later and after replacing a lot of things that gave me a car with constant performances.

Thx

On a lightly modded 3.8, "good" is an understatement. I'd call it crazy.

[articacid]

that is a crazy trap for what you have done.

if you can cut a 2.0 60', you should def be in/near 14's.

[Shirl]

Looks like 14.7's or so if you get the 60' down to 2.0. Figure for every tenth faster the 60' is, the ET will be .2 faster. You have a killer MPH. There are cars that have run in the 13's with that MPH (including mine in the past). I say throw some DR's or slicks on that car and race it like it should be raced. What DA are you running at?

[vanbibber]

96 should be good for mid 14s for sure. maybe even better.

Euh... what do you mean by DA ? :rolleyes:

[98Camaro3.8]

DA means Density Altitude. It was altitude that it actually "feels" like to the engine. Hotter temperatures result in less dense air, which means it feels like a higher altitude than it actually is. Same goes with barometric pressure and dew point.

Anything over 15°C (at sea level only) raises the density altitude at a rate of 500 ft per 1°C.

You can use a calculator if you know the weather values from when you raced. http://wahiduddin.net/calc/calc_da_em.htm

A 96mh trap is kinda rediculous. I trapped 94 running a 14.8 and alot of people told me my trap was high. That should tell you a bit about yours.

98Camaro3.8:
I try the calculator and the result is a DA of -274 with these values:

Elevation: 30
Air Temperature: 10
Altimeter Setting: 1010
Drew Point: 6

That means the engine was actually making more power than it would have at a standard day at sea level. The difference is only marginal over sea level, but there'll be a bigger difference over an 84° day.
