Performing Different at Night Time

[Annu Kumar]

Ok guys is just My truck or does everyone experience this. In the day when there is sun out My truck is always feels flat and sluggish in terms of acceleration. When I go get groceries late at night about 10Pm The truck feels So smooth In Acceleration and goes like a rocket. Must be the cooler air or something right?:dontknow: Thats why see some guys going to the strip at night time for better Et's Maybe:dontknow: :dontknow:

Same here...

Because it's denser air. Right before and right after a rain storm is when all cars perform better.

well then,my truck should run great all the time.It's always getting ready to rain or just rained this time of year in florida.Air is so thick you can cut it with a knife!!:rock:

Install a water/meth mod...you will love the results...no real hp gains will be detected by a dyno but your seat of the pants will know the difference.

The water/meth injection creates that heavy air situation and drops the temperature of the air entering the intake considerably...it is a requirement with the Roe TMTS, but I had it long before the sc...and there was no doubt that in the heat of the day, WOT acceleration was tangibly improved.

Hot weather, higher DA (PA corrected for Temp and Humidity) = less power. At night the temp is lower and usually your DA will be lower also. This means you will have more power. That is why we ask people if their Dyno numbers are SAE corrected. As that will change the numbers.

This thread got me thinking about cooler air, lower temps etc..When I was at Boomers, he was putting ice into a canister on the drivers side of his truck. I think it was to help cool the motor between runs at the track..If there was a similar setup where you could run your fuel through a canister to cool it before it goes to the injectors, wouldnt that help?..just thinkin out loud..lol

Actually, Chuck Berry had it wrong; unless he had cooling systems issues with his car because on a moist day, the air is less dense. A reduction in air density reduces the amount of oxygen available for combustion and therefore reduces the engine horsepower and torque.

But yeah, these engines don't like heat. That was one thing I really noticed prior to installing the Stage 2 flash on my QC. I could get ONE good pass, then I could fry an egg on the intake manifold. After that the knock sensor held back so much timing it was REALLY sluggish on second and subsequent passes. The flash cured the late timing problems and made the engine's performance way more consistent.

That would help and you can order them through Jegs, Summit or any of those race parts suppliers. You fill them full of ice and replace once its all melted and you can use them for other fluids I imagine

I thought this was going to be a thread about Viagra.

I was thinking of a reusable deal with dry ice in it..That might work better..course when the truck sits between runs, the dry ice might freeze the gas..dunno really...And after the gas left the can, I imagine it would heat back up pretty quickly, so maybe this is a dumb idea after all..:dontknow:

Dry ice would be too cold, just use regular ice. When dry ice begins to heat up, the gas it produces is carbon dioxide so you would want a way for the gas to escape the container.
