I know this question is weird, but when it's cold outside, my car feels slower! I'm currently running e85. I have been noticing this for awhile. I had my car on 13 psi the other day with cool weather and it felt good. The next mourning, I turned the boost up to 15 psi, and it was ice cold outside and I felt a decrease in power. It did not pin me to my seat at all. Do you guys know anything that would cause a car to lose power in colder weather? Could I be spinning tires and not even know it? I'm making 500 whp at 15psi.Does the colder weather effect e85in anyway?

 

my car feels fast as balls in the cold lol

 

ice cold weather + 500whp= wheelspin but in all seriousness you'd be able to tell if they were

 

My car is weird, it feels faster in warmer temps.

 

It's actually hard to tell if my wheels are spinning at higher speeds. I can tell in lower gears, but it's almost impossible at higher gears. I might have my tuner strap it back on the dyno and check. My car was tuned during the summer time at 100 degree temps.

Have your tune checked out I got my car tuned on a 100+ degree day I made 434whp I came back when it was 70 degree it made 454whp added 1 psi 465whp

When had 434 I didnt spin my tires at all, now that its colder with 465whp i spin all the time 1st,2nd, sometimes 3rd

 

You are probably just getting used to the car. I wouldn't speculate anything without putting it on a dyno for some real proof. The butt dyno can be very flawed.

 

Agreed. Boost is like any other hard drug, you build a tolerance rather quickly.

 

Not running too lean or anything with the cooler air right? If you go too lean will definitely feel like the car is bogging down almost.
