What do you get when you bolt a supercharged 1,000bhp engine, hitherto found under the bonnet of a four-wheel-drive monster truck, into a home-made motorbike chassis?

Most people would probably say “trouble” or possibly “a ride in an ambulance”. But for engineer Nick Argyle, it seemed the obvious thing to do when tinkering with some bits in his garage one day.

Argyle had built his own monster truck some years previously before selling the chassis but keeping the whopping 8.2-litre Mopar V8 engine. Lacking the space to build another truck, he decided that the ideal home for the supercharged powerplant would be a two-wheeler.

Called the Rapom V8, the result is the most powerful road legal motorbike in Britain, with between 1,000 and 1,200bhp depending on the boost from the Littlefield supercharger. That makes the Bugatti Veyron, the fastest car in the world with 987bhp, look rather tame.

And if you thought your neighbour’s SUV was a gas-guzzler, the Rapom consumes a gallon of pure alcohol ever four miles. Fortunately Argyle only uses it for the 10-mile trip to his local dragstrip in the Cotswolds and then only in the daytime as the bike lacks headlights. The frame, constructed from massive, 3cm thick steel tubing, is extra long to prevent the bike flipping over under hard acceleration and as it tips the scales at 1,000lb, a reverse gear is needed for manoeuvring.

With such a surfeit of power, just two forward gears are needed in the API racing transmission. Stopping power provided by racing brakes gripped by six-piston callipers.

didnt know where this was appropriate, mods feel free to move it if need be >_<

thats the radiator not the cooler. it isn't intercooled. the supercharger runs like a drag cars. straight into the intake.

by the looks of where the handlebars are, you would almost be leaning against the back of the blower when you ride it.

I cant see the handlebars :S im sure there there but there hard to see...

also the seat sits heaps far back from the bars, stearing this would be fun...

Would not want to experience a blower Back fire...... shrapnel for breakfast. :laugh:

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
