^i believe that coupe did remove everything, and he has a bypassed exhaust (basically an open header)

My exhaust is stock other than the two mufflers, kept the stock piping to keep the sound close to stock as possible with a little grunt when I go WOT. The Y-pipe I have really opened up the top end of this car thats for sure. I am trapping 1.5 MPH more than my last visit without any other mods.

So the coupe took off almost his entire exhaust system?

That just proves that the 6 speeds are the way to go. The coupe is 100 pounds lighter as well.

I didn't even lower the tire pressure, kept the front at 32 Psi and upped the rear to 38 Psi.

I had my spare in the car with about 1/4 tank of fuel.

I am going to hit the tracks this coming weekend, but this time with my buddies really sticky tires (Dot approved tires or street legal).

The will be on 16 inch steelies, but just want to see how low I can drop the 60 foot times. My goal is to get a 2.0 and this time with some good power shifting.

i went on nico and found the thread that he posted about his time.

looks like it was about 60 degrees outside, and he completely unbolted his exhaust after the cat and pulled a 13.91 @ 99mph. I think it was Sacramento race track. Not sure the elevation there.

this is the exhaust as it is now, so he doesnt have to unbolt it anymore.

Imagine if you took off your exhaust like that, you will be well over 100 MPH trap speed wise.

The CVT isn't as fast as the 6 speed. Only advantage they have is it's easier to launch.

When I did my 14.4, there was a 3rd gen 3.5 4AT that had the basic bolt ons, and was running 14.4-14.6 most of the day. when he disconnected his exhaust and the temps dropped at the track, he was at a 14.1

Check this out, guys that have dynoed and run at the track with a valid time. The text is copied from another forum. Curious to see as i don't know your weights to populate the calculators. Obviously won't account for the y-pipe though..





So I did a quick search for a power to weight ratio calculator after a debate with a guy on another forum and came across this site. I used one of their calculators to find my HP using my best 1/4 mile time and it came out to exactly what I dynoed at at FT a few weeks ago. Below is a list of a few of the formulas they use. http://www.ajdesigner.com/phphorsepo...horsepower.php

EDIT FOR LINK
http://www.ajdesigner.com/phphorsepo...horsepower.php


Estimate of engine horsepower after a quarter mile run using the trap speed method.

Determine the increase in engine horsepower when an after market modification, race or performance part has been installed with trap speed.

Calculate engine horsepower after a quarter mile run using the ET method.

Compute estimated increase in engine horsepower when an after market, racing upgrade or performance part has been installed with ET.

Dyno correction factor. Factor corrects horsepower for normally aspirated internal combustion engine to a standard humidity, pressure and temperature after dynamometer measurement.

Calculate a vehicles power to weight ratio. Acceleration is related to the ratio.

According to that formula I am making

Agreed,

Could not even got WOT in 1st gear and when I shifted really quickly into 2nd, had to go 80-90% throttle still!

Damn these tires to hell.

Did you add your weight in the equation? You might be able to get a rough estimate of the 298.144 - your previous dyno of the Y-pipe gains...
