Here's something I thought you guys would find interesting. I know there's an interest in making our 1.4T perform. Here's a recent episode of Car Science called "Stripped for Speed". They test the theory of 100 lbs = 1/8 second off your 1/4 mile ET.

The test car is a stock 1992 Nissan Centra with 110 hp. Curb weight is 2116 lbs. Their first pass was an ET of 16.65 @ 84.1 MPH. Guess how much weight removal it takes to make this thing do a 15.38 1/4 mile pass @ 91 MPH. :th_coolio:

Thats pretty interesting.

that is pretty interesting, but they should have left the intake and exhaust systems intact, ran it, THEN striped those two sets of parts off and ran it again. That would have painted a much clearer picture.

but great find, really enjoyed watching it... especially those precious 12oz's being added to the pile.

I enjoy some of the stuff they air. I agree. Whose knows how much power it picked up from removing those restrictive parts. Maybe they could've just thrown them in the car to see if any difference was made.

LOL, yeah, I'm glad that extra 12 oz came off of a nice looking pro-driver.

This was done a LONG time ago by some magazine. I probably still have the magazine somewhere. I need to find that magazine because I think their results were far better.

...ah, no roll (in the hay) bar to protect her assets...oops.

More than weight affected this, because its not a linear relationship between weight and speed.

• stock weight:

84.1mph = 225.3*(110hp/2116#)^(1/3)
16.65sec = 6.214*(2116#/110hp)^(1/3)

1400.3 = 84.1*16.65

• stripped by 508# weight:

91.2mph = 223.0*(110hp/1608#)^(1/3)
15.38sec = 6.290*(1608#/110hp)^(1/3)

1402.7 = 91.2*15.38

...the "numbers" look.s pretty 'consistent' to me.

My exact thoughts. I'd hate to see that go to waste. She definitely has some balls. Nice ones too.

What I meant last night is the relationship between weight and speed is not a strait line, at least on this car. In addition there were other factors that played in. Pumping loss and Coefficient of Drag both played a factor in reducing speed.

If it was straight relationship, the third run should have been closer to 16.04 seconds based on the weight/time relationship of the first 2 runs, but it was much shorter. Which obviously means the more weight loss, the more time per pound is shaved off in conjunction with reducing the square footage of the front of the car.
