Yea, I've seen that new Volvo engine, its called the D16, and it is a beast! Even with all the emissions crap on it still sounds realy cool, and from what I hear they will snap your neck when the truck is unloaded. As for the C-15 talk, my company runs 4 Kenworth w900 tractors with twin turbos and honestly they are not much to talk about. We had a Cat 425 in a 91 Peterbilt and that thing would pull 2 of those new tractors backwards at the same time! Personally, I am a Cummins guy, but Cat has made some good engines in the past.

you can unplug the wire to the engine mounted fuel filter  and get a plug from cat tht fits it and wire in a 100 ohm resistor you can get that at radio shack  it makes the computer think you have at least 5 pounds of boost and perfect fuel temp so it helps your timing out . you get about half a gear and quicker spoolup out of it  .you can also unplug it and hook it back to the filter if it goes in for warranty work and it wont show on your ecm  total cost is about 5 bucks

I've got 2 of 'em.  An 05 & an 07.  They are miserable.  My 05 has been bumped to 550hp, which by the way will cost you 1800.00 through CAT for the additional warranty to cover the HP, (that is if you're still under warranty).  I bitched how shitty the truck ran for almost a year, so I got the uprate for free to shut me up.  Fuel mapping has been recurved, which did yield more power & MPG, catalytic mufflers replaced with old C-15 mufflers which resulted in better MPG but a little slower to spool up.  I drive this truck & don't let my drivers near it.  It runs OK but my new truck coming has the Cummins ISX 500HP in it, which will spank both CAT 550's.  The 07 is a factory 550 & seems to run a little better but is still unimpressive.  The boy I have in that truck came out of a Cummins ISX 565HP & I still hear him *** about how much better his Cummins was at his last employer.  Anyway, stay away from the ACERT at all cost.  MPG SUCKS.  

As for performance upgrades, Google Haynes Performance.  They make some stuff for the CAT motors that could help you out.  Also Pitts. Power as mentioned before.  Lastly, I think Donaldson makes a set of reuseable high flow air fliters for the trash cans that yield some more boost.  Hope that helps.

C-15 acert, C-13 acert are twin turbo the C-9and C-7 are not at least in the truck applications. C-12 is older engine they never put vva's on it I think the latest were mbl or something.

I have to laugh at your ISX spanking an Acert. I pass ISX's all the time I even pull past 600 ISX Cummins. My Cat is a C15 Acert 475Hp. Anytime you want to bring that 500 horse turd around I'd be happy to show you. We put a 100hp power wire on a 485ISX in a 2008 Pete. So it "Should" have been a 585..Still passed it. I ran a 600 they are a lil more work to pull on but, I can still do it. A properly tuned Acert is a damn good running motor. As for fuel mileage. The ISX junkers are getting 3.2-3.7 in the 08 triaxles. I get 4.3-4.7 .

im a x cat mech, your yr of trk should be a 6nz cat engine, single turbo, pdi manifold, and a borg warner turbo for a 600, its non waste gated, 1.32 a/r ratio and a 78 mm intake wheel, is worth 80 hp, then add a marine/industrial cam for a c-18, pdi also has a reground  cam to this specs, it worth another 65-80 more hp, all  without changing any factory computer settings, still need more go to the 58 series injector (6nz runs a 57 series), there worth about 60 hp but will need to update he computer with injector codes, you also can update the codes and tls and fls settings  with stock injectors ,but when you do that the engine becomes rough with the higher of setting and you get pryo temps spikes and engine temp isues, turbo and manifold will keep engine and pyro temps under control,and cam will also,stilll need more go to 59 injectors there worth 200 hp, but youl have to convert to a holset 1919 turbo, good for 60 psi, but the engine better be in perfect condition, and have a liner protrusion of 4- 6 thousands to hold the pressure
my current set up is a 2ws 550 , 600 hp engine flash, 57 inj, borg warner 600 turbo, manifold and the idustrial cam for a 800,  dynoed 774hp at the wheels,or 970 flywheel, pyro (pre turbo temp) is 1180-1230 degrees( after turbo temp is garbage, if the heat hits the turbo (1350) it to late and you start cracking heads, any ?s
