hey guys,

do you think the 4.6 is a little under powered for a SCREW? i drove my brothers 5.4 SCREW and it felt pretty sluggish. how do you 4.6 guys manage? and what kind of mileage does the 4.6 get in a 2wd SCREW? thanks for any help you guys can give me

 

sluggish compared to what? For a 4.6, my screw does seem to pick up pretty well from 0-60 no problems. The 4.6 is great for heavy commuting since i spen 2+ hours/day in heavy Los Angeles rush hour traffic. I get 19-20 mixed city and highway ever since I bought the truck. When you said the 5.4 felt sluggish, is that compared to your 4.2L?

 

My first SuperCrew had a 4.6 in it. I had tried both the 4.6 and 5.4 before getting settling on one and yes the 5.4 had more pep but I felt I could live with the 4.6 and I did so for 3 years.

Gas mileage was around 15-16 in the city and got up to 20 on the highway. This was a 4WD.

I guess all things are relative. The 4.6 was a drastic improvement over the 2.9L V6 I had in my Brono II. My current SCrew has a 5.4 in it and that is a better combination, but the 4.6 did work. I never ran into a situation where I needed more with the 4.6.

Speaking of the 5.4 being a little sluggish, when I took some 2003's out for a test drive one of the SCrew's with a 5.4 did not impress me at all. I also had a similar experience with a 2003 Expedition. They were not much better than my old 4.6. I suppose it's possible there may be some lemons out there or maybe the transmission shift points are not properly calibrated which would explain the lack of acceleration. The one I have now certainly is no slug and is quite an improvement over the 4.6, but I do miss the gas mileage. My first tank of city driving was around 11 MPG.

 

yea, i was talking about my 4.2. i know there is a HUGE weight difference in the trucks...but i was just expecting more i guess from the "5.4". but..i do like what i am hearing about the mileage with the 4.6...that is totally what i would like. i dont get that good of mileage in my 4.2!!!

 

Get your ***-meters calibrated!!

My friends 4.3l Blazer feels quick because its small! My truck doesnt throw me into the seat, and it doesnt feel that fast, but when we line em up, all he see's is my tail lights!

Its got nothing to do with feel in large trucks.

 

My 2001 4.6 Screw with Superchips is plenty quick. I tow 2 different boats and it has plenty of power towing also. No complaints here.

Oh yeah, I get 15 city and 20 highway

 

Ok, I visited the local speed shop and had my ***-meter calibrated!
The only problem is, my 5.4L still walks off from my friend's 4.6L SCrew like he's runnin' bad gas. I don't know, it might have something to do with a couple add-ons to my truck (cat-back exhaust, AF1 intake, and SuperChips Microtuner). Guess my ***-meter still needs a little fine tuning.

If power's your thing, buy the 5.4L and mod it with what you can afford!

If I were just driving to work I don't think it would matter. But when I've got the coolers, the stove, the dutch oven, the chairs, the tent, the clothes, the food, the bikes, three kids, the wife and myself and I'm climbing up the Sierras from the east side heading to Yosemite I'm glad I have the 5.4.

 

If you live and drive in Florida (read that to mean flat and sea level), a 4.6L is more than enough if you don't care about leaving people in the dust, so to speak. The 4.6 does an admirable job for such a small engine.

Where the 4.6 falls is at speeds over 55, up hills, at higher altitudes, carrying a heavy load, and hauling a heavy load. That's when the torque of the 5.4 comes into play.

I needed maximum towing capacity, so went with the 5.4 which comes with a bigger rear end than the 4.6. I had a 4.6 in my '97 SC 4x4 and I was impressed with what that truck could do with that small engine.

I'd be satisfied with the 4.6 in my SuperCrew. I can live without worrying if I'm going to spin the wheels at every intersection whenever I'm infected with the heavy foot syndrome.
