If I went the Limited/Overland route it would most likely be a sleeper, maybe some mild exterior hints as to what it really has. hope that helps.
also are the AWD systems on an SRT and Overland the same?? I know the SRT has QT on demand and overland has QT II, what's the difference? I know the SRT AWD system can handle well over 500hp. If they are close or the same, i'd think the QT II could handle about that as well.
If you decide on a SRT8 check out the Red site. I know there are some stock ones and some Built ones for sale. I know Navyavi is selling his over there for around 40K and it's well worth it (0-160 in 16.8 seconds
What are the prices on the Limited/Overland vs the SRT8 in your area?
Should be about 10K difference? With that 10K you could forge and stroke a 5.7 or
replace the 5.7 with a 392 or a 426 or
Turbocharge it up to 7psi safely on the stock internals.
The SRT8 and the Laredo both have the same trans housing (W5A580) but the internals are different. The W5A580's are known for their trans issues (leaking seals/failing electronics/shuttering).
The SRT8's transfercase has issues when you drive it like you stole it alot or if you mess with the ESP!
The SRT8's are known for horrible freight train sounding brakes.
The SRT8's crank and cam are forged but the rest of the internals are cast and the pistons have a very very small ringland so becareful if you push it.
Please don't get me wrong it is a very nice and fast vehicle, I am just pointing out known issues to make you aware.
The Limited and Overland have the 545RFE trans. I have had no issues with mine YET (we will see how much it holds soon enough
) - nor have I heard of any so far. According to my sources it will hold 500whp no problem, 600whp is pushing it...I should point out that the Torque Converter
is the weak link as it can only handle around 400whp.
The NV245 Transfercase used in the Quadra-Drive II system is bulletproof and has been problem free sitting behind a Stage 3 racing 545RFE Trans powered by a supercharged 392 installed on a Dodge Ram Super Bee. This 5100 lb. vehicle currently runs 11.29 @ 115.77 MPH, 60ft. - 1.521 seconds, 330 ft - 4.501 seconds,1/8 mile - 7.095/94.44MPH, 1000 ft - 9.359 seconds, 1/4 mile - 11.294/115.77. The NV245 has also ran in stock form many many Baja races with no issues.
As for the (ELSD) Electronic Limited Slip Differentials 7.9 front 8.3 rear in the QDII system. I know they have held 7psi with no issues so far...we will have to see how they hold up to 10,15,20psi's when I get mine back. The 15 and 20psi's will be after I install my Stage 3 race trans.
The stock internals on the 5.7 are not made to push them too far as they are cast and the ringlands on the pistons are very very small...keep an eye on your EGT's and get better internals
The 5.7 block has a thicker piston wall than the 6.1 and it also has MDS which can be used with most cams and provides a 20% increase in fuel economy if you drive like a grandma!
All in all it's up to you and how far you want to go. There are also small differences in each model year and the 05 is the only one with a second owner transferable warranty (7/70K at $150.00 to transfer within 30 days of purchase) all the rest are lifetime for original owner or 3/36K only for second owner.
