I just happened to buy a Rolls Royce Viper 301...

[Johansson]

Hello guys!

I got an offer I couldn´t resist on a Viper 301 yesterday, the guy who owned it bought it from Everett Aero for a jet pickup project but when it arrived it lacked the starter, the ignition modules and some kind of pressure pickup.

I know the guy and he isn´t exactly handy so he has had the engine in storage for a couple of years without making much of an effort to source the parts needed, I got it very cheap just because he was tired of the whole mess.

In a week or two I will pick it up (he lives 500km from here) and get a better view of what parts I need to source, I know that the starters are very rare and bloody expensive if one can be found. I have an idea of fitting a hydraulic starter and use an IC engine coupled to a hydraulic pump instead of an electric starter, much cheaper and easier to move around as well since I won´t have to drag two truck batteries with me.

I would appreciate any kind of information about the 301, PDF manuals, tips and tricks etc etc.

Cheers!

Wow! Nice!

Here are some articles on the Viper Turbojet engine.

Here is a cut away picture, notice the evap tubes   and the starter/generator in front.


Here is a 301 starter/generator for sale

Since the starter also serves as a generator you will have to install some sort of clutch system on your hydraulic pump or the turbine will spin the IC engine once it spools up!

Hi Erik, thank you very much for the links! You are right about the hydraulic starter, might have to rethink that one.

The thing is I don´t want to spend more money on a starter than what I did om the engine, so unless I stumble upon a cheap electric starter that can be modified to fit the Viper I will have to figure something else out.

I haven´t found anything about where the 301 was used and what makes it different from the 100 and 200 series, anyone who knows?

Cheers!

Hi Anders

Good one :-)

I think Ernie might have a 301 or two in storage. He might have some documentation

[Johansson]

Indeed John, should be fun to have a "real" engine to blow some gravel across the yard with.

I´ve asked him and he said he would check it out.

You are a gold mine Erik! The Powerjet homepage seems to be weird though, I can see the pictures on my cellphone but not on my computer and the link to the homepage is dead.

Can you please upload the schematics as pictures so I can get them?

Hi Anders

Anytime!
I think I fixed the links & also uploaded the pictures.

Thanks!

[stoffe64]

Fantastic,congratulations on the new toy,now you will have to build a bigger kick and sit on top of that viper, hehehe

[Johansson]

He he, no kick build with this one Stoffe.

I think the Rocket Launchers crew hit the end of the scale with their 130kg thrust kick, more than that and you don´t really want to be standing on top of it steering by bending a pair of steel runners.

[Johansson]

The Viper is loaded and ready for its trip back home tomorrow, damn this girl is heavy!



Cheers!

Hi Anders

Nice cradle .

Heh heh , she'll take up a bit of room in your workshop ;-)

Hi John,

Yeah, that is the downside. At least it can double as a coffee cup holder when I am working on the turbine bike.

Cheers!
