Thread: Viper Modding

Just picked up an 08 srt viper, wondering what the best bang for your buck mods are for them? love the car will post pics soon

Exhaust, high flow cats or headers, sct tune... That will be some extra ponies right off the bat.

Headers/exhaust... go check out the Belanger system

Unless I missed something no one has cracked the 08+ PCM. The only "tuning" is a Mopar PCM which you will need if you decide to run no cats. I prefer the American Racing Headers over the Belanger and that is what I had on my '09 ACR.

Depends on budget.

Intake, exhaust, and headers. Might gain 80hp at the flywheel

If you want more then that, do cams.

If you want more then that, and you've done the above mods to get it breathing better, supercharge it. You'll be up in the 700's then.

If you want more then that, turbo is pretty much the only way to go.

Or you can always toss NO2 on it, for a quick hundred, but I'm not a fan unless its a drag car. When the tank runs out, you got nothing.

You might be right... just did the tune on my 03 and didn't check for the gen 4. The Belanger is a better choice for street driving. If you plan to go to the track, pick up a set of the American Racing headers with a nice cat back. I have Corca track with Random Technology high flow cats.

On my '06 I went with the Corsa and Hi-Flow Cats + Intake. I did an SCT tune, but as mentioned think your '08 needs the Mopar PCM. After that is done, let us know as the decisons after this are bigger ones and ones that will cost you a bit more $$$

Congrats! Post some pictures up. I have Eibach springs and a Vipar suspension kit I need to sell if you are interested in lowering your car...I just installed KWs yesterday.

None of these mods will work unless you want to spend the $20k+ on Motec, the factory computer has not been cracked. UGR and Hennessey are the only ones I've seen mod an 08+ Viper, both were running complete Motec standalone. They changed alot more than most people think; drive by wire, Higher compression, cam in cam vvt.

Are you looking at performance or visual mods too? If the latter is correct, then some D2's to set it off!
