Any truth to certain track prep?
 

I've read things things like removal if headlight(s) foglight(s) intake filter, deflating reaer wheels and inflating front wheels can be of benefit at the track.
However, there's just as many people saying the opposite.
So my question is are any of these valid?

I know inflating front tires will provide less roll resistance and deflating the rear is for traction but the rest I'm unsure of.

If one doesn't have traction issues would inflating bother the front and back be beneficial?

Thanks

Anyone care to offer insight?

Iv heard with a cold air that sits behind the headlight taking the headlight out is good for .1 usually never heard removing fogs

it does depend on tire and pressure for the rear. you can run too little. on a radial you want as much pressure as you can hook on

as far as headlight. if you have the air filter behind it you could see gains. when i sprayed my 4.8 i took out the headlight and air filter. picked up maybe a .1

if traction is no problem yank off the tailgate as well.

the colder the air through the intake to the mainfold the colder the charge is to the engine, the more horsepower it will make, ive seen bigger gains pending on weather. tire pressures can fluctuate from track to track!

Ways to go faster. 1 put front tires on the tire max pressure. 2 rear tire pressure all depends on the tire. 3 remove right headlight to ad cold air into engine 4 remove all you can to remove weight. Like seats, tailgate, spare tire and etc.

Much appreciated. I'll do all of the above. Fingers crossed for getting into 13's on Friday night!

I am a big fan of leaving the gate on. It is well known that the tail gate on will provide better areodynamics. The weight it puts on the truck is in the absolute best location, and I along with plenty of other people have not seen gains from taking the gate off.

I have see a few guys have very solid numbers showing an improvement with the gate on and up. Nothing major but on a fairly fast truck I think it was .1 or .2 and something like 3 mph faster.

I will say from my own experience, my buddies truck picked up almost .1 every lap when he removes his headlight. He has a home made CAI where the filter is open right behind the headlight.

My truck has a SLP CAI that uses an airbox to enclose the filter. I modified the box so it has a large hole behind the headlight. When I remove the airbox lid and headlight I also get about .1 quicker.

With me also being 4WD, I inflate all 4 tires to 40-42 to help with rolling resistence. I take the tailgate off because at my power level the weight loss helps more than the aerodynamics.

We dropped .1 by removing tail gate
