Well, one of the reasons why people (myself included) won't buy Hennessey is the way they've treated their customers in the past, and their rip-off pricing. When it comes time to mod my go-fast toy (Z06), it's easy choice - shell out big bucks just to have "Hennessey" on my door sills, or piece...

Right..... because refusing to drive an auto when it's clearly superior, is the ultimate measure of manliness. There're many great feats in this world that test the boundaries of a man, trust me, driving a stick is not one of them.

Are you taking the manual ratios? Because with the auto, I have: 3.59x4x4.1=59:1. Keep in mind if you compare the manual, then the auto's torque converter makes up for a LOT of the difference. For the RRS, the transfer case is 2.93, and 1st gear on the 8 speed ZF is 4.71. So they put in a 3.33...

Hence it's offered for the 0.5% of owners that wants a real Range Rover. Even that might be exaggerated! On the plus side, the new RRS with low range and 8 speed ZF would have an absolutely amazing craw ratio. Might even be better than designated crawlers like the Rubicon and Power Wagon.

What if we go past the looks and analyze the hardware underneath? The old Sport was HEAVY as hell, one of THE reasons I'm not into it, at all. The new one is 800+ lbs lighter, that's no small feat. Not only that, offroad ability, from clearance to water fording, actually improved. The new full...

550 lb-ft I'd believe, with really good intake/headers/exhaust, and whatever cam they throw in there. 400 hp @ 3200? No way in hell! Simple math says you need 656.5 lb-ft at 3200 rpm to make 400 hp. That's way beyond the technology of those old big blocks. Hell, my LS7 would have trouble making...

Yeah, I hear that about the 3V motors. Wish they offered the old 2V with the 6R80 transmission, and modern 3rd gen chassis. Guys in cargo vans have put over 1/2 million miles on them! Another spec I dug up: 10" of travel out back. Yeah it's still no Range Rover L322 or LC200, but pretty damn...

IMHO, the latest generation of body on frame SUVs from Ford is the most under-rated. SUVs, like dinosaurs, the best species evolved near the extinction... I've got a baby Expy - an 06 Explorer. The frame is one of the toughest in its class - fully boxed, 55% stiffer than previous gen, and 444%...

Don't know why you guys are so against a modern electronic range selector. The macho factor? Keep in mind big bad 18 wheels of steel, and 54,000 lbs GVW tour coaches, run across the continent, day and night, in all weather, using electronic push buttons to control either automatic Allisons or...

Zeke, Very few "luxury" and high performance engines won't run on regular, just depends on how well they run (how much timing they retard). Ferrari has done testing in remote Chinese villages where equivalent octane was a little over 80, and their high compression V12s made it no problem...

That can be said for any comparison between a more purpose built, vs stock vehicle. Take a highly modified Jeep - you'd pick a stock Rubicon for both on-off road. Take a highly modified track car - you'd pick a stock BMW M5 for both street and track. Take a purpose built commercial flatbed...

Weight diff may not be as small as you think, Edmunds list 4525lbs for the 1999, and 5636 for the 2011 model. That would definitely swing things in your favour!

What was the weight difference and rear axle ratio? You also have to keep in mind torque management on newer truck purposely tone down off the line torque. Almost every instrumentation testing of modern, low torque, 6/7/8 spd transmission vehicle beats their older counterpart of similar weight...

Better stick with a 19' pole then... What cracks me up is 15 years ago, a 300hp in a truck was a powerhouse. Now, all of a sudden, it's an underpowered "car" engine? And the whole torque argument might be valid with an old 4 speed - torque was needed to make up for the large gaps in gears...

You need to be in high management at EPA! Last time I checked, that WAS America. Nowadays CAFE killed big blocks, EPA killed fuel efficient diesels, and pretty soon, my Detroit 6V71 (the most beautiful sound this side of a Lambo V12) won't be allowed in California, thanks to CARB. Yeah I'm...

Basically gave your own answer! Wheel, and more importantly tire weight, only affect acceleration and braking forces. At steady state cruise, they have zero effect, theoretically. Their effect is also magnified if the vehicle is light, high hp / weight ratio, and of good aero to begin with...

In case anyone is not aware, just want to add that as of 2012 MY, the PW comes with 66RE instead of the ancient outdated 545RFE. This new transmission is a true 6 speed, using the same gear ratios as the diesel 68RE. This makes the PW an even better workhorse! (Note this transmission is...

Very few 71-series Detroits are turboed, though an 8V-71T can make serious power! On 92-series, the blower has a bypass. When turbo boost kicks in, they're feeding the engine directly. Again, they have a blower, not supercharger (the Eaton blower makes 0 psi boost)

$44k ??!! These days an 03/04 MkIII can go for $12 to $15k. For $44k it better includes lifetime warranty and modding contract from previous owner!

Greg, Are you talking about the old Detroit 2 stroke marine motors? Because I have to say, I've never seen a modern 4 stroke diesel with a supercharger and turbocharger. And for those that don't know, a Detroit needs the "supercharger" to run. Otherwise, it's 2 cycle combustion would have no...
