Yeah, I want a CAI too. I hear it adds about 1 mpg for the V10, for $200 it might be worth it. that is true though, those things will save you fuel!

BTW, at your fuel prices, and the PSD getting 20 and V10 getting 15mpg (assuming we both mod as mentioned above), after 100,000 miles, the PSD will save about $3,000. Your savings is $1,500 and mine $240 per year. Where you will really save though is when you sell your truck, because you will recover $5-6k of the cost. So really you 'll break even in less than 2 years. It will take me about 10 years to break even though with the mileage I drive.

Read it again. The V10 can pull the same hill faster.

I just pulled 14,000 pounds over Eisenhower Pass the other day. Can your V10 pull the same hill faster with the same load?

Well of course, cause he will come up with something that will make the v-10 sound like god touched it. You know the v-10 guys need to realize that yes their trucks might be able to tow the same amount but what engine will last longer doing all that towing.

So whats supposed to be so cool about the V10's? they don't last long, all their power is in the higher RPM band so taking off from a stop grossing 20k must really suck, and they are slow... pointless engine. V10s should be in cars where high RPM has a purpose, not a truck that weighs 8000 lbs.

What is the torque like on a decently modded V10 anyways? i ask b/c i don't know. decently modded means spending less than around $2200...

My truck @ 21K lbs combined weight,and up a slight incline merging on the highway:

Tom's 6.4L @ 19,500 combined weight on flat ground:

23 seconds for Tom's 6.4L PSD, and 27 seconds for my 6.8L 3V, Only 4 seconds difference even though I was approx 1500lbs heavier and running up a slight incline.

You know what I just realize is that the v-10 guys are just as bad as the LS1's guys.

And what gearing did the psd have? I bet not 4.10's.

You make it sound like 5200 rpms is "screaming" and excessive. That's only 1700 rpms more than most diesels spin to nowadays. My Tbird has the 4.6L in it-same engine technology and design. I tore down the original engine when I swapped in the built engine at 215K miles. After 215K miles of 6500 rpm shifts and literally thousands of dragstrip passes and daily driving duties, I checked dimensions on every internal dimension of the engine. EVERY SINGLE COMPONENT in the engine was within original factory specs.

Plus how many more times would you have to fill up compare to the psd if you ran it 1700 rpm higher?

And if you put 4.10's in the psd it would probably gain another 5 seconds or maybe a little more so that would put it 10 seconds or more faster. That's alot since the v-10 makes more power then the psd.
