Who in here has proof that an Intake or Exhaust gave them any HP or TQ?

Hey Guys,

I been reading up on these eco boost motors and doing a lot of research since Im trying to get my truck to a certain HP. The only way to do this is simply by going with a full custom turbo kit and tune. The factory exhaust and intake will give you the same amount of power as all/ if not most of the aftermarket exhaust and intakes out there. From what I read and talked to a bunch of "trusted" tuners, guys I been dealing with on all my projects thru the years, these trucks simply dont pick up power from Intakes or Exhausts. I want to see if anyone has actually put their truck on the dyno after a tune or before with just adding and intake or exhaust and picked up any power at all? Need some guidance on how much power I can really make with TUNE/EXHUAST/INTAKE/DOWN PIPES vs tune only. From what I know from one local shop they did a tune on a truck and than added all bolt ons and the truck barely picked up 3-5HP. Is this true? not sure but I do trust the shop, and this being a Raptor Forum maybe other members have better input as far as real hard proof of it giving good power.

My truck feels faster type of answer is not what Im looking for. Im looking for I either had the truck at the track and ran a way better time after the bolt on mods or my truck made this much more power on the dyno vs a my stock truck before. Stock trucks will make dif power #s on a dyno depending on truck and weather/air conditions. So looking for a truck that has been dyned before and after with bolt ons with tune or without.

I know Intercooler will make the truck more consistent but def not more power.

The Great Intake Face Off - RESULTS!

I realize that this for a different forum and a different vehicle, but there is usually no data like this available to compare modifications. BTW, for you FRF OGs, this is a test BigJ put together before he got his Raptor.

Improving performance is a cause and effect process. Every "performance" part you add will have impact but sometimes the change is not of any real advantage like, perhaps the peak HP occurring 50RPM sooner. CAI have been proven time and time again to offer no real advantage on modern vehicles. The stock systems are designed very well and have very little restriction. As for exhaust, reducing restriction will net you a performance gain, but only if you remove the restrictions from front to back. The exhaust can only flow as good as it's worst bottleneck. So to see gains, you need to open improve it from the manifolds back (i.e. turbo, downpipe, cats, and all the exhaust from there back). Now consider that the stock exhaust from the cat back (the part everyone replaces) on most new vehicles (including the Raptor) is the least restrictive part of the exhaust. So all of these bolt on mods are never going to net you any real performance gains.

That is exactly what I read before I posted this and was wondering why so many people think that switching out their K&N or whatever filter for an Intake would give them power.

AGREED. Thanks for the input.

Crazy to see that here! I am a long time LXF member just recently got a Raptor so started hanging around here. Great information there!!

I gained 72HP from my could air intake and 119 HP to the wheels with an exhaust

Incorrect. A good aftermarket IC will absolutely allow more power than the stock IC.

So if the truck is cold and does a dyno run it will dyno less than a truck with the intercooler on it?

With a tune right?

Yeah man ! I use a Whopple piggyback tune thing, its good for at least 850 wheel horsepower at the crank
