well yes boosted cars should benefit also but not as much as a n/a car will. but i dont see how a boosted car will gain more, can you explain your logic behind it. Because i am pretty sure i am right here.
both n/a and fi cars will gain power due to the drop in iat's. But the na car will be able to fill its cylinders with the cooler more dense air where as the fi's cars cylinders are allready being filled with a certain amount of air because of the turbo or supercharger so the volume will stay the same. Assuming that the owner is still running the same boost pressure, the bov or bypass valve or wastegate will keep the boost the same reguardless of the air temp.

To be honest I cant really explain my logic....I am just going off of what I have seen....03/04 Cobras are known for getting hot. I am just saying I have seen Cobras dyno numbers drop 20rwhp on the dyno after 1-2 pulls my Mach never dropped more that 5-7rwhp on the dyno.

colder air = denser, more oxygen per volume.
assuming boost stays the same, a turbo car will be packing in more extra oxygen than an n/a car. throw in lower iats and egts which would allow it to pack in even more oxygen while keeping the same volume of air, and youll see why a turbod car benefits more from cooler temps than a n/a car.
my ta loves colder weather, but my fiances wrx loves it more. its a much more noticeable difference in her car when the temps drop.

you said it will be packing more oxy? you cant just say that with out giving a reason as to why. a n/a car will benefit from lower iat's also so you can rule out that arguement. and egt's are a problem area created by boosted cars not a help (n/a cars dont have problems with egt's usually) so you can rule that out also.

Thank you for verifying. I'm sure you are right that a n/a car will benefit more than a FI car, that is why I stated it. Colder air will keep that turbo cool and more consistant but it's not like it's getting more PSI. Also this isn't a grudge match, he's an aquaintance of mine. As for me weighing 300 pounds more than the neon as stated above, I doubt it. The FRC's are proven to weigh anywhere from 3000-31xx pounds. I've seen a Neon weigh in 3000. We are definatly going to race soon, unfortunatly it's been raining a lot here. I'll get two races out of him, a 20 roll from me, and a speed of his choice. It should be a good match I think. I'll make sure to get it on video for you all to watch.

From my experience, FI cars (I have two right now, including a skittle) really pick up in cold weather. It's very noticeable. As for the skittle, it loves the cold air. Boost is referenced to atmospheric conditions so you get more than just the extra air from it being denser. The computer adds timing which makes the boost come on sooner and harder. Also, if the car has a boost controller, the driver can turn it up higher in colder weather, fuel permitting. Traction is always an issue, but from a roll it's usually ok. From a dig, things would be interesting...
The vette is gonna lose if the neon guy can drive. That thing should be trapping 120+ mph or so against a vette that does what, 11X?

Your car isnt on a fixed amount of psi like a turbo car, manifold pressure prolly goes up a few psi when its cold out in your car. A turbo'd cars wastegate will regulate the boost and a supercharger generally has nothing to regulate boost, So in my experience supercharged cars do seem to pick up more than a N/A car in the cold weather.

no i dont see why, i explained why for my reasoning can you explain yours more.
you said it will be packing more oxy? you cant just say that with out giving a reason as to why. a n/a car will benefit from lower iat's also so you can rule out that arguement. and egt's are a problem area created by boosted cars not a help (n/a cars dont have problems with egt's usually) so you can rule that out also.

It was 108 degrees outside at my last tune and my tuner said intake temperatures were between 130 and 140. The best the car put down was 364whp. That was August. Two weeks ago the same shop had a dyno day. Temperatures were in the high 40's and low 50's. The average of the three pulls was 388whp. Same setup on the car. Same dyno. Same giant fan facing the FMIC. I doubt many naturally aspirated motors could pick up 25whp. I think forced induction cars might like the cold weather a little more.

well good kills! i really wanna run against one. when i was heading home one night on the highway. one came up next to me and spooled up his turbo to try and get me to run. but it was kind of raining here and there. so i wasnt going to risk it. but good luck on the next run. KEEP US UPDATED..

There's a difference between loosing power on a hot day and actually GAINING power on a cool day.
You're not gaining power on the cool day, you're just loosing it on the hot day...
If that makes sense....................

I picked up a solid 2mph in the 1/8th alone going from the summer in 80deg weather to 50deg winter weather. No other changes, even the tune remained the same.
