Has anyone seen any articles on this?

Google was useless.

My old man has a decent sized RV and is a total dog on it's way up mountain sides etc. (we're talking 35 MPH on the shoulder over the grape-vine).

We've kicked around the idea of centrifugals, twin screws, roots, head work, etc. but it always comes down to how much of a pain in the ass it is to do motor work on an RV.

A wet nitrous system seems like it would be the easiest thing to do. On open road, the thing works fine. It has plenty of power to do what it needs to do. It's only those trips up mountain sides that it needs some help.

I'm thinking a plated system or maybe even single nozzel wet system. The thing has a fuel injected 460 in it. It's been modified with a Banks induction and exhaust system. I think that's about the only engine mods it's had.

Before alternate suggestions start flowing, a super built 460 with all the race trimmings is not an option nor is it an economical solution. Converting to a powerstoke diesal is also not an option.

We're still kicking around the idea of installing a centri-blower but that would be last resort. The thing doesn't need help very often. Only occationally.


Here are some consideration factors:

Nitrous on an FI 460
100-200 ft lbs of additional torque
Easier breathing at higher elevation
Fully remote activated


What are the down sides to introducing nitrous on a low RPM application that's chugging it's huge ass up the side of a hill?

I should also mention that the torque converter in this rig is already an after-market, heavy duty upgrade (at the behest of the RV shop). A more efficient, after-market trans cooler is already in the works.

A wet system would be the way to go. It will give it that kick it needs. I have never heard of any one doing this, but it can't be too hard. Most of the guys I know with RV's have blowers.

Yeah.... that's still an option but a blower usually means higher octane gas. I'd like to get this done with a large enough shot that it'll make the torque target above but still be able to run 87 or 89 octane gas.

I figure that with a nitrous system, we'll able to jet the thing so that we can run safely on low-grade.

How about one of those tailpipe turbo setups?

I would definitely go with nitrous...and about 3 bottles worth. You could get crazy and build a nasty 460 but it would kill you on gas mileage. With the spray it would be otherwise stock (while driving normally) and then open the flood gates when needed.

but then your gonna have to get some kind of timing controller, cuz it will be even more of a dog if you pull 2-4 degrees of timing for the nitrous right?
When your not running nitrous i think it would worsen the power loss due to the loss of timing.

Nitrous is great for torque. The HP gain is accurate to manufacturers' claims, but the torque gain will be almost double. I think it's a good idea..pulling some timing might be a good idea, though. Make sure it's a wet setup as well.

Have to make sure that the nitrous gets activated at 2500rpm or higher,otherwise it will overload the enigne and parts will break.

Single nozzle wet type set-up will work best for ya,and be the least expensive.

As for the ignition timing look into geting a MSD 6AL and the adjustable timing control for it.

Also,has it had a differant cam instaled? That would probably help.

It wont work. You'll blow that sucker ski high on the 1st pull! It's too much load/weight to be adding a jolt of HP/torque like that. Especially against Mr. Newton!

Maybe a 50 shot, but much more and you are flirting with disaster!

I dont see it breaking,but I agree that caution needs to be taken and like I said,only active above 2500rpm, full throttle,untill it gets rolling fast enough to disengage it.

And I think a 100hp shot would be more that enough,but anything over that maybe look into a progessive controler.

What you need is more torque, and in a perfect world a turbo set up would do you justice! But in reality a H/I/C swap would be the best application for your delema. JMO

Daggs,maybe look into getting a rebuilt 6-71 and building a blower set-up,lol.

lol at the 6-71 maybe, but the concept is good!

I don't see any reason a nitrous kit for an EFI wouldn't work. You mentioned having some Banks induction parts on there already? I bet Banks Engineering has some ideas for you as well, or may even be able to recommend a kit.

I gotta admit, when I saw the thread title, I thought this was a joke.


Are the tranny and diffs solid enough to handle the boost? I'd hate to see it blow one or the other with the sudden increase of power....especially with that type of load on it.

How about regearing......?
