New intake

Just installed my new intake! S&B. I was skeptical of the difference, but after the first test drive I'm more than sold. Way more throttle response and the turbo spools up much faster. I can actually hear the thing start to sing at about 2500 rpm. Too cool.
If I can manage to stop mashing the pedal to the floor I'll probably get better mpg, too. At 75 on the highway it used to run at 2050-2100 rpm. Yesterday I was consistently at 1900. That's gonna equal some savings for sure.

New MBRP 4" stainless exhaust going in on Monday.

Raptor pump showing up mid-week.

Okay, so maybe after dropping all that $$ the savings will be a while to come to fruition, but hey... what's a guy to do when the bug bites you......

SCRATCH THE ITCH!!!!

haven't heard that one yet... PMS?? Bet its good though.

Love the helicopter definition! Have a buddy that's a mech. for USCG birds - he describes a helicopter as a million little pieces of highly engineered metal that all want to get away from each other as quickly as possible. My favorite is his description of the nut that holds all the blades etc. down onto the shaft: Jesus Nut - cause if it fails Jesus is the only one thats gonna save your ***.

PMS= Powerstroke Mod Syndrome

I doubt you'll se any MPG gains...even if you can keep your foot outta it
Just curious how you could loose a 100-150 RPM @ 75MPH
with a different intake???

That's good!

Your probably right, but I'm told I could/should get upto 10% gains from the intake.
Cuda, you know WAY more than I do about this so I'm not sure about your question. But does it stand to reason that if the engine is breathing easier and running easier would the rpm's drop as well? Maybe it doesn't work that way, but for whatever reason I'm running 1850 at 75 mph! That's gotta equate to more efficiency.
Your thoughts...??

My thaughts exact.......

With torque convertor locked you have a mechanical lock from flywheel off engine to the tires on the road. If your doing 75mph your engine has to spin "X" amount of revolutions to move the truck down the road at a certain speed no matter if you make 1000hp or 100 hp.

Unless my reasoning is flawed...............

I agree David's97f350, I was concerned his torque converter may have been slipping before the intake was installed.

Your new intake will mainly reduce EGT's. You may get a little better throttle response but I highly doubt the MPG hype. Most aftermarket stuff unrealistic claims.

BTW: There is no cure for PMS
