Turbo Charger or Super Charger? Bad for tranny?

Thats more correct 
And horsepower is horsepower. If it makes you all feel better my friend doing his 11s for 2k build with a gtp doesn't even run a filter at the track. The hot air doesn't make that huge of a difference. If you bring in cold outside air, its going to warm up in the intake/throttle body anyway. Also, cars have run carbs/intakes for years, sucking in hot air and they have made absolute gobs of horsepower with it. A bigger intake is a bigger intake, unrestricting it with a $15 filter will do you just as much good for your car as putting that $15 filter in a $200 box.

i honestly don't think i've ever seen a supercharger for the LS4. Even if there was one, you'd have absolutely no room to mount it, run belts, etc.
Also, you'd be going through tranny's like you wouldn't believe. Even though it's "HD", it can barely handle stock power.

How much does it pull? I bet the air isnt much hotter then the air sitting in that stock box.

If you don't plan on doing anything else to the car though, maybe a cold air box might help you on long runs in city in summer. BUT the times for winter, and the times when I am on highway going like 60-120+mph, I think It matters less.
Honestly when I got my first intake, I got it to save gas, and save myself the many trips to get a cabin filter replacement(I also didn't know what engine I had in the car too at that time, like what is a i4,v6,v8 etc? back in like 07 or 08) But got a ebay intake(still feel ripped off, so I told myself from now on, it's custom build intake if I ever do another air intake). Didn't know how to install, just asked a friend with more knowledge at the time. Strapped the pcm, watched him do everything... Drove off, didn't care for gas mileage(of course I never got higher than 22mpg ever yet... my past year I have been getting 15-17 especially with turbo now...). Became power hungry. A very serious disease I must say, like why does it matter how fast the acceleration is etc... I dunno till this day, I guess the rush from modding for power is just addictive.

depending on the setup the temps can be 50* higher! engine bay temps can and are in most cases 120+* and right above the exhaust cross over i would guess they are more like 140+ i know on the DOHC, and 3800's after 108* it pulls 1* then at 122 it pulls like 3* of timing going up to 6* for like 140*
so you could potentially loose a lot of timing. if you have access to a tuner you could set it so it doesnt pull timing... i have heard people have done dyno tests and have found with boost it doesnt matter the temp of the air, so long as your getting enough air. for example an NA car could benifit from a FWI where as a SC car likes a big 4" dia neck filter giving it more air. im am thinking that for NA it could be the lenght of the piping that forces the air to increase velocity and that higher velocity of the FWI carries thru the TB and speeds the airflow thru the intake manifold... and since the Turbo or SC is doing the work it just needs more air.

that is one of the resons why i got the trans cooler for my monte to help every thing to keep cool. plus having a extra fan put in for the cooler as well it comes on when the engine fan comes on. i got the dealer to put it on when i got the monte. they comected the fan to the radiator fan as well i know heat is a killer of every thing. from hp to life of the power train as well as lack of cooling reduces of the fun and enjoyment of what you have done so far as tun cia to built engine and trans. i doubt that any one hear will due what i done but i would also sugest to put one on for the longjevity for the trans as well to ensure to help it keep cool to help the hp to stay there. pluse i dont think any one here wants to put in a 3-4k moded trans for there monte to match there hp sooner then later
