Really? Is that why Porsche can get 500 hp from a 6 cylinder and your not getting close to that with a 5.4 V8?

Its not about discplament, but how well its built

Craftsmanship and inspired enginering is a replacement for displacement any day

I know its apples to oranges, but that is a very broad statement

 

Which Porsche 6 cylinder is producing 500 hp?

 

^^^I was about to say that!!!!!

why do you think drag racers use 600-700 plus cubic inch motors to do over 300 mph in a 1/4 mile?!?!

lmao twin turbos ftw.... and you're comparing that to a 5.4... Can someone put twin turbos on a 5.4 and run the numbers please?

I found an article on turbos on 4.6 and 4.2 motors. Can't imagine the numbers on a 5.4. Here's a quote from the linked article.

"The 4.6L 2-valve motors are usually looked down on by their 4-valve brethren,
but we ran a twin-turbo system (from HP Performance) on a mild 4.6L 2-valve motor that produced
over 700 flywheel hp with just 13 psi of boost."

There really is no replacement for displacement.

 

idk guys i drive some pretty fast 4.2's at work. They are factory supercharged 4.2L 4V V8 in the 06-09 Range Rover, and 06-09 Range Rover Sport

they would definitely beat my truck in a race

 

The statement was there is no replacement for displacement.

I found a replacement, more HP out of a smaller displacement engine.

Hell, the 2011 mustang V6 is rated at 305 hp and the 5.4 is rated at 310. Im sure I could find 5 hp somewhere...

Im saying ingenuity can be a replacement, if your smart about it, you can make these 4.2L really fun to drive.

Yall sound like those people who only drink imported beer because, well its imported so it HAS to be better.

 

I can't remember all the post I was going to comment. If I remember right, I agree with Raoul, 4x4 and 4x2 make a difference.

I loved my ol 302, it ran like a beast. Kinda just ran good, no problems.

Im NOT saying my truck is fast just simply showing a friendly race. I have no problems with V8's. Just for Gods sake showing me and my buddy racing.

 

 

That was actually a good read jake. I might have to save that one.

 

ok to be clearer, a 5.4L scab could be quicker or slower than a 4.2L depending on what gearing the trucks have. if you have a 3.08 rearend and my 4.2L has a 3.55 rearend it will be a lot closer than if i had the 3.08 also.

yeah and what rearend does your 4.2L have? and a 2010 5.4 is probably the 3v which we were not talking about in the category of ones we would have a chance at. it would be interesting to find out how the 4.2L fairs against a 3v 4.6 or 3v 5.4L but we i already said i would probably lose the the 3v ones.

i am 25 and my 04 and my 08 V6s were my 7th and 8th vehicles. i already had my 96 trans am that would smoke anybody on this thread, but really, who give a crap? i would have got another trans am but i couldnt afford it. insurace company would see another trans am and they would kill me with the bill. i already paid $224 a month for insurace on the trans am with no accidents. after wrecking it it would be probably about double. i got my V6 f150 because i wanted an f150 and i wanted a manual. unfortunately a manual only comes with a V6 or a diesel. well sorry but 30k+ for a diesel is out of my reach. i bought my 04 and my 08 for myself. parents didnt help at all with them. the 04 was used with 23k and it was $13k. my 08 was brand new, i actually had the dealers look for it. they drove it 139 miles because of a dealer trade and was around 20k once the remainder owed on the 04 trade-in was added on.

what do you mean by stock gears? you do know that there are more than one right? and the 4.2 isnt meant to go fast. either is the 5.4....its a freakin truck....

it depends...can the 4.2L be a rental? i would ramp the hell out of it to keep up if i had to lol.

thats correct. ever wonder why the 4.9L I6 was replaced by the 4.2L and why the 5.0L was replaced by the 4.6L and the 5.8L was replaced by the 5.4L? because they make more power and are more efficient. but they have less displacement. its not just ford. dodge 5.2L replaced by 4.7L, 5.9L replaced by 5.7L, chevy 5.0L replaced by 4.8L, 5.7L replaced by 5.3L... i could go on forever...my 96 trans am was a LT1 350ci 5.7L V8 rated at 285hp, but in 98 the LT1 was replaced by the LS1 which was still a 5.7L but was 346ci and they were 305hp and moved up to 325hp by 02. its everywhere, engines can be made smaller and have more power and be more efficient. so there IS a replacement for displacement.

 

both f150s were run on the same area of the same road.
and just fyi, a 4.2L manual against a 4.2L auto with the same setup are two different animals.
my 04 heritage 4.2L 5spd with 3.08 rearend reg cab longbed 2wd. 1st vid is 0-60, 2nd vid is 0-100 but the clutch slipped in 1st gear so use the 60-100 in the 2nd vid and the 0-60 in the 1st.

my 08 4.2L 5spd with 3.55LS rearend reg cab shortbed 2wd

and just some food for thought, my dad's 00 sierra. 4.8L V8 rated at 275hp with about 65k miles in this video, well maintained. push button 4x4 but it is in 2wd. it is a ext cab shortbed auto with a tow package, rearend unknown but i would guess 3.73s. sorry no sound. both of my 4.2s would beat it. the 08 would beat it easily. 04 would have had some trouble i think.

This thread is just ridiculous.

 

X2 but at least its entertaining.

 

Not one of them beat my old and tired 5four 4x4 w 3.55's, Close! Well maybe it's not so tired. Thanks for posting
