No pics yet, but I'm new to the Expy.

I have the baby motor. 4.6l
Going to be doing the GOTTS mod tomorrow.
Thinking 3/2 lift, on 17" Black Rhinos
Not sure of tire size yet. Input would be great.

Just looking for overall advice on performance, and any other helpful hints and tips!

Welcome . mods are on my signature. Feel free to ask questions.

You got a big boy! I like that. I'm interested in the Silencer delete, and throttle spacer...what does the throttle spacer do for you?

THANKS!! The throttle spacer gave me more low end power, take off, at least 1 more mpg. And the silencer delete makes it sound like a real truck if you do everything at once you will feel a lot of difference. If you need help on doing the silencer delete let me know.

 

[droogle]

I'm definitely interested in learning both. Anything I can do to make it feel like a real truck, would be great. And wouldn't mind the improved MPG. lol

l found this picture, the one on the bottom is what you need to take off.

Awesome! Something to add to my list to do tomorrow. Also replacing the dang EGR valve. 157k on it, and has never been cleaned or changed. Surprisingly, not burnt up to badly.

welcome to the site...not sure if i missed it but i dont see what year you have...also...i beg to differ on the performance of the throttle space...how can it increase air flow when air flow for more low end torque and increase when it is only increasing distance...search throttle body on the forum becuz this is and has been a hot subject with a lot of information on it...contreversal for sure

 

[BIG GREEN FORD]

It gains more air in the intake, its been dyno Tested people gain up to even 18 horsepower, and 25 foot- pound of gain in torque

 

[DetroitDarin]

No. Effin' WAY a throttle spacer helps an engine MAKE HP. Big Green, I luv ya like a brother, but Serious :bsflag: - The spacers were designed to help prevent heating the air intake charge; there's nothing else it can do.

Now - by effectively lengthening the intake track sometimes torque is raised. But we're talking about a 1"? spacer?

No way. Never, ever, ever, happen.

The Gotts mod is worthless, but the spacer is probably MORE worthless.

If I saw a back-to-back dyno, on the same day on the same truck on the same dyno I MIGHT be convinced, but not if the dyno was done by a shop who sells the spacers.

Want a good power-adder? Try a tuner; pick a brand.

Maybe it was cuz I did all the mods at once. Sorry for the wrong info guys

No need to apologize - here's what tends to happen with mods:


Somebody buys a mod. The install the mod. The mod causes the truck to lose power down-low but up through mid-range the power rushes back to where it was stock and the driver SWEARS he/she can now FEEL the power increase.

Or - somebody gets a baseline dyno for their truck. They use the dyno Schmedlapp Tuning...air temps in the 90s. Next year they add a bottle of snake oil to their engine and re-dyno and the plots now show an increase in power! holy crap it WORKED! Except it didn't - what they did was dyno on a different dyno, with air intake temps in the teens.

OR - Somebody baseline dyno's their truck. Then then pour in the snake oil and re-dyno on the same machine within the hour and holy-lord LOOK a gain of 5hp at 2800rpms. But...below 2800 and above 2900 they LOST 12hp. But...see? PROOF they 'gained power'.

OR, OR - They spend $1500 for a mod that gives their truck a 5hp gain at 5000-6000 rpms. Yup. Real honest gain. WHILE at 5000rpms. So they paid $1500 for 5hp across a 1000rpm band they almost NEVER see while driving.


Once I had a car gain 25hp across a broad range of RPM and still had the same peak power rating. All the gains were below peak - and the mod worked awesome (removed a cat from a turbo charged car). Gained REAL solid power because the turbo would spool faster; get faster into boost. Yet the plot showed that at the limit the cat was NOT restrictive whatsoever.

See how goofy 'making power' - specifically - MEASURING power can be?

 

[droogle]

Well. Any tips and tricks??? And year is 2003

Back in the good 'ol days there was a saying "there is no replacement for displacement".

Stick in a stock V-10 and have reliability and some more pulling power. If you want to be really different stick an Allison or manual 6 speed behind the V-10.

I'm pretty sure there is a thread on here where a member did the V-10 swap. Interesting read even if your not going the route.

 

[DetroitDarin]

I am a firm believer "Forced Induction" is the replacement for displacement. Whipple Charge that *****.

Be warned - adding systems to engines tends to "never work out, long term" unless it's a Flyin' Miata turbo to mazda miata.

I agree with Darin.
In today's multi port fuel injected motors, there is no possible way a throttle body spacer can generate more HP. In certain instances with carbeurated engines, a carb spacer could generate more HP by allowing the fuel more time to atomize with the air. With fuel injected engines, the fuel is still sprayed at the exact same point. You could add a 10' long tube to the intake and not change a thing!
I did the Gotts mod to my Expy, as well as my sister's f150. Does it help? Never pulled a dyno run to find out. But for the $7 in parts to make the mod, I thought it was well worth it! Giving my engine the ability to pull more cool air only makes sense.
I do know that "cold air" intake's are an oxymoron. How can you pull more cool fresh air into your engine when the filter is stuck in a housing directly inside your hot engine compartment?
Still on the fence about the silencer delete. One of these days I might get ambitious and get an intake tube from a wrecking yard and try it.
