    The wait is finally almost over...

    From reading your previous posts, you went through a lot of crap to get where you are today, but looking at those pics...man, it had to be at least somewhat worth it. Your car looks awesome.

    Gen IV - Nitrous & Dyno Vid

    The timing would be the issue...normally, you'd pull a few degrees of timing when running nitrous. Yes, you could get the AFR in line by changing the fuel jets, but you'd have to reliably trick the PCM into pulling the correct amount of timing. Race gas might help, but it would be at the...

    Gen IV - Nitrous & Dyno Vid

    Reflashed what? I'm assuming they mean "Mopar PCM" since no one has cracked the rolling encryption, but I'm all ears...

    Gen V dyno - New Vid

    Here...read this article: http://www.hotrod.com/techfaq/hrdp_0405_chassis_dyno_guide/viewall.html 4th gear is 1:1...it stays 1:1 regardless of rear axle ratio. That's why the rear axle ratio is a variable input for any dyno...if you told the dyno it was a 3.07 and you really had 3.55s...

    Viper V-10 recieving upgrades in future?

    You are right, but they have to make them cheap enough for mass production, and also reliable enough to get through at least the powertrain warranty, and longer if the company that goes this route doesn't want to look like they put out engines that die as soon as the warranty is up.

    Gen V dyno - New Vid

    Well, if a Gen IV is an S2000 with a V-10, then a Gen V is an S2000 with a V-10 and a nice interior. You are right...there's definitely a different vibe in here, and that doesn't appear to be a good thing.

    Gen V dyno - New Vid

    I don't think that's too much to ask.

    Viper V-10 recieving upgrades in future?

    Where exactly would you suggest a cutout be installed on a side-exhaust Viper? There's just no room due to how it is routed. You can see where it runs down the side sills in the pic above, but that is because the body panels that cover it have been taken off. And both examples...

    Viper V-10 recieving upgrades in future?

    The clunkiness you aren't seeing (but is still there) is being absorbed by the torque converter. Additionally, the only Challengers I see offering Chrysler's MDS are automatics, not manuals. http://www.dodge.com/en/performance/2013/

    Viper V-10 recieving upgrades in future?

    Is it an automatic, or manual?

    Viper V-10 recieving upgrades in future?

    The dual mode exhaust makes sense on the Vette because you can easily bypass the mufflers with the layout they have chosen. On a Viper, bypassing the muffler really isn't an option, at least not with the current configuration. If they ran the exhaust out the back, it could be an option. AFM...

    Viper V-10 recieving upgrades in future?

    The downside? Heat generated, and extra weight to try and dissipate said heat. Look no further than the curb weight difference between a ZR1 and ZO6 Vette, or a ZL1 vs. Z/28 (or SS) Camaro, etc. You don't get something for nothing. I'm still waiting for the inevitable "must be DOHC"...

    My second round of mods-Car is going to RSI

    Are they planning on replacing the oil cooler? I'd probably go ahead and have that done in case any junk from the engine made its way into the oil, and possibly the cooler. The last thing I'd want is little pieces of metal from the old oil cooler circulating into my brand new engine...

    small oil leak

    If it is the lines, I'd replace everything. If you want to go aftermarket, I'd go with the ones from Dan Lesser (Viper Specialty): http://viperspecialtyperformance.com/catalog/product_info.php?cPath=22_34&products_id=196 I replaced mine with these...not the easiest install in the world...

    LED Replacement Lighting Thread

    They take the standard 194-base bulbs, one each.

    LED Replacement Lighting Thread

    The top cover around the steering column directly behind the steering wheel comes off...I can't remember if it has a couple of screws or not (I think it does)...after you get that off, it should be right there.

    small oil leak

    I'd place a healthy wager on the oil cooler lines.

    My Amazing Gen 5 Viper Adventure!

    I don't know how common it is, but it seems right in line with the results I've seen from similar combos. I just know which car this is since the owner frequents another forum I'm on (LS1Tech), which is where I first saw the video.

    581 RWHP - it's a heads/cam car done by LMR.

    Question on Mixing fuels

    I just don't even have a generic OBD scan tool, so I have no idea what is possible to scan with a Gen IV.

    Question on Mixing fuels

    Yes, you need this to display the A/F ratio based on the fuel you are running, but they still all measure in lambda. In other words, the sensor only knows lambda, and the box is doing the calculation after that measurement to display the A/F ratio based on the user's input of what they think...

    Question on Mixing fuels

    Will they advance timing? No. Will they pull it in a big hurry? Yes. The Gen IV computers are very sensitive to anything even remotely resembling knock, and they'll adjust accordingly at the expense of power. I'd expect no less from the Gen V given they use the same engine (mostly).

    Catch can plumbing

    Question on the vented cap...does it allow air to flow both into and out of it? It needs to do both in this case. The typical vented cap like that will only let air out, not back in since it isn't filtered.

    Question on Mixing fuels

    It wouldn't matter if it was narrow (0-1V) or wide (0-5V)...either will operate on the same principle.

    Question on Mixing fuels

    There was no MAF sensor on the Gen I-III Vipers...there is on a Gen IV/V. O2 sensors are lambda sensors...in closed loop, they aim for a lambda of 1.0. Lambda is fuel agnostic...doesn't matter if it is E85 or good old 93 octane, it will get you to stoich either way - that's how flex fuel...
