dont forget about the diesel's.

they have some kick.

 

yeah until 4000 RPMs when the revs run out. I'm sorry but torque does not equal speed/accel. A diesel just cannot be balanced to produce high-rpm power.

To OP:
Shame on you for thinking that your stage 2 STi can stand up to

Imagine the aerodynamic efficiency of those tires.

 

um...

 

well, explain all those diesel trucks that run 10's.

watch out who you race, they might end up handing you your ass and your smug grin all in one fell swoop.

If you produce enough torque, anything is possible. BUT, a similar gasoline engine can typically achieve much more precise ignition and be balanced for much higher revs meaning more power up top. Diesel vehicles will give you a nice kick in the ass down low though...

That's part of the fun, don't you think? :tongue:


EDIT: I take that back, I suppose gearing can be set up to take advantage of the high torque of a diesel engine. It would put a large strain on the driveline/tranny, but possible.

 

those gearboxes are already putting up with 1000+ lbs ft of torque. chances are if they change the gearing, they're going to be replacing the parts with something that will handle the power.

i drove my friend's 2 foot lifted f350. i don't remember the size of the tires, but they were massive as well. putting out somewhere around 800 lbsft and it was slow as balls. but then again, that's because the gearing was low as it was set up for offroading.

around where i live, there are tons of extremely fast diesel trucks. they will destroy my wrx, and i'm pretty sure they'll destroy an STi as well. STi's are quick, but keep in mind they are only rated 70hp more than a normal wrx.

i'm just meandering through my thoughts now, pardon me.

 

I have never heard of a dodge truck with a viper engine in it. That sounds interesting. Also this thread confused me cause almost everyones name starts with f haha... flyn, fly, fox, fire... I kept doing double-takes to see who was saying what

Anyway, keep showing those good old boys whats up I suppose, just be careful if you see a gun rack

 

I have never heard of a dodge truck with a viper engine in it.

Dodge produced this truck for a while. It was called "Dodge RAM SRT-10" and used the 10 cylinder from the Viper SRT-10. I just don't see the point of adding an engine like that to a 5500 pound truck... at least the turbodiesels make sense...

 

:rotfl:

The idea that a diesel truck can't be fast is absurd. There are hundreds of trucks out there that run mid 12s or quicker, lift kits & mud tires included. The quad cab and/or 4x4 models weigh 6500-7000 lbs too.

Then there's the ones that look stock:

Yep, no top end power in a diesel at all!

Ram SRT-10:

The Ram SRT-10 runs 13.0s from the factory. The quad cab is automatic-only and runs a second slower. They do get quicker because most people who buy them also mod them, and when dealing with an 8 liter engine you get results quickly. They get Viper-type seats and brakes to go with the engine too.

I don't want to get in a pissing match with you, but what I mean by no "top end power" is that there is no top end! Diesel redline tends to be around 4000 RPM. Here's a snippet from wikipedia (I know it's not a credible source, but convenient and in this case, accurate):

While diesel engines tend to have more torque at lower engine speeds than petrol engines, diesel engines tend to have a narrower power band than petrol engines. Naturally-aspirated diesels tend to lack power and torque at the top of their speed range. This narrow band is a reason why a vehicle such as a truck may have a gearbox with as many as 18 or more gears, to allow the engine's power to be used effectively at all speeds. Turbochargers tend to improve power at high engine speeds; superchargers improve power at lower speeds; and variable geometry turbochargers improve the engine's performance equally by flattening the torque curve.

:baaa: And what's the point? The Viper will run low 11s with the same engine. You don't get much more utility with a truck like this, since the suspension is designed for track rather than load. I'm not saying that a truck can't be fast, I'm saying WHY WOULD YOU WANT IT TO BE? Plus with all that weight up front, a truck will get mad understeer. Buy a nice Silverado for the utility and a Corvette for the speed :screwy:

 

Different strokes, etc. People get attached to certain types of vehicles due to culture, who they hang out with, geography, whatever, and someone somewhere will want it to be fast. The market and aftermarket responds, and there you go.

We cling to our own, comfortable preferences and do all of the namecalling, just as there are many groups of people out there that think modified Subaru's are "stupid". It's easy to get caught up in it..Months ago my wife and I came across an Evo driver at a gas station who gave us the evil eye because we were in my WRX. We had a good laugh. :rotfl:

Thats funny, yesterday I passed an evo and he waved at me haha

 

I was cruising down the freeway one day....going about 70...next thing I know this black truck goes flying by me like I'm standing still....it scared the crap out of me...I never saw it coming...yep...it was one of them dodge srt 10's!

 

Ray, putting things into perspective, as always... :tongue:

I really didn't mean to namecall and I really have nothing against trucks, even diesel trucks. In fact, I almost bought a Tacoma instead of my WRX. I just don't understand anyone who would compromise the utility of the truck for speed when it's completely out of it's element. But as you said, some might say the same for a modded WRX

I wasn't directing the comment at you.

Thats funny, yesterday I passed an evo and he waved at me haha

Yep, I get that a lot of the time, as well.

 

i'm curious, what does the fact that diesels are low reving engines have to do with there hp/tq abilities? i got lost on that. engine rpms does not determine max engine output. i happen to drive a 10 wheel truck that makes 1550lb tq at 700 rpms and shifts at 2000. but yet it seems to move 60,000lbs nicely. just because it's not a conventional way of thinking doesn't mean it doesn't work very well.

 

horsepower = (torque * RPM)/5255 at a specific engine rev

Your power (HP) depends on how much torque the engine makes at a particular RPM. Physically, power = torque over a specific rotational speed, hence the revs in the equation -- measure of angular velocity. Thus, it is important to understand the torque curve of a car to apply gearing. Put simply, a very torquey engine will tow very nicely, but unless the torque is applied at high RPM, the power is not produced. Power *typically* defines acceleration and top speed. Think of a body builder who can lift a lot of weight, but is very slow due to all the bulk.

BTW, as stated earlier, if the transmission is designed with a lot of overdrive gearing, the low revs of a diesel engine can be negated by the large torque output, but that requires extremely durable gearset and driveline components.

 

Driving a modded truck fast is so stupid. Especially on the highway. If you have to quickly turn to avoid an object you are going to flip it. The center of gravity is very high on these trucks. In my opinion it is a death trap. Not only that it is more dangerous to every one else on the road. :screwy:

 

mmmmm, imaginary numbers.

 

speaking of the srt-10...has anyone seen the video where a guy does a burn out and flips over? Its pretty darn funny, ill search around for it a post a link

Lol at the video about the srt. And that movie is awesome! Part 1 and 2. "chainsaw arm"

 

Then there's the ones that look stock:

yeah thats fast....

 

:bs:

 

Some, trucks are fast. But not many of them are.

 

Some Subarus are fast. But not many of them are.

Just a quick reality check-in. :tongue:

 

What's considered fast? I consider something to be fast only if it's running single digits.

Someday I'll own a fast car.

 

i went for a ride in a '09 lamborghini gallardo superleggera this past saturday.

the owner drove the piss out of it for me, hitting 110 in only a few seconds.

call me crazy, but save for the gearshifts on the flappy paddle gearbox... the car didn't feel all that fast :screwy:

i mean, i know a 550 hp car is going to be fast... but it didn't feel fast.

 

And the guys who run 7s in the quarter think the cars that run 9s are slow.

The guy who runs 14s for the first time thinks he's got the fastest car on the road -- until he runs 13s for the first time.

It's all relative.

 

agreed.

 

Bugatti Veyron.

 

if you like paddle shifters

Even the Veyron doesn't seem to break into the single digits stock:
