Yes I know cooler air going thru the intake is good but I had a huge boost in performance this morning. Was about 60 out when I went to work. I hit the gas like usual making a left turn from a dead stop and ended up drifting the turn ( yes it was awesome ) when I did not intend to do so. I ran 89 octane thru the jeep last week was about 1/2 tank of gas then went back to 87 octane this week. Any ideas why I would experience a gain this noticeable when I have never had one before in this wheather?

 

Way too many variables to form any positive conclusions.......the butt dyno is very unreliable. Ours runs better after a wash and wax.

 

Just weird its never ever run as good as it did this morning. Biggest thing that got me is I didnt go past 1/4 throttle which is less then usual on this particular turn.

 

was it raining? maybe someone spill some water on the turn and it was frozen. maybe someone spill oil on the road.

 

Tranny probably slipped

 

I'm not the only one?!

 

Mine rides smoother after a nice wash and has more throttle response when it's 70 degrees or above.

 

Stickers make mine run like a rapped ape.

 

Nice dry spot where it happened

 

You know what they say, It always runs great before its ready to **** the bed.....



haha...j/k

 

Mine runs like a beast if I fart into the intake before startup.

 

Rapped ape? Is that an ape that break-dances to rap music?

 

60 is warm! The average annual temperature where I live is 50.5 farenheit (I just looked it up) and it goes as low as -22 and as high as 95.

I notice the same thing as you but notice it in reverse... when it gets "hot" out, it feels like I'm down on power. I think it just comes down to oxygen density at different temperatures. Similarly, you notice varying power depending on elevation. A quick google turns this up: "horsepower increases by about one percent for every 10 degree drop in intake air temperature".

 

Yup, that's why mods like cold air intakes (snorkels that draw cold air from outside of the engine bay) and the IAT relocation work.

 

Hmm guess Ill have to look into that cuz I need more power outta the jeep its always sluggish.
