Rotrex Superchargers

Uncategorised

Rotrex supercharges work on a principal of a turbine the same way that turbochargers operate. For this principle to work the turbine spins at very high speed.

Rotrex achieves speeds of up to 250,000 rpm using planetary gears and its own oil system, the result being high pressure from a compact unit the size of an alternator.

This produces a linear increase in boost pressure and power band right to the red-line using very little crankshaft power so what is done with the throttle is transmitted directly to the rear wheel. There is no heat build up so components run cooler which reduces fatigue,exhaust temperatures are lower, efficiency over a turbocharger can be up to 10%.

Other Advantages:

  • Wilder camshafts can be used to take advantage of the boost increase
  • Lower compression means easier engine starting cam chains and shafts less stressed
  • Less cost as $ per hp cheaper than normally aspired engines
  • Progressive power means no stressed engine parts
  • Nitrous injection cools the intake charge reducing knocking effect.
Cold Kiwi Rally

Cold Kiwi Rally

My Triumph next major outing was down to the annual Cold Kiwi Bike rally. The Ruapehu Motorcycle Club  formed this iconic rally in 1972. Waiouru on the slopes of Mount Ruapehu is the venue every year in September. My bike was entered in the burnout competition which...

The Roundabout

The Roundabout

Whilst I was partaking of a Sunday ride and navigating a roundabout. Probably coming in too quick,on quite a lean angle the new exhaust headers became hooked on the road. This  caused the front wheel to lose direction and resulted in the bike throwing me off while...

The Show

The Show

Come November I entered the bike at the 2018 NZ Motorcycle Show in Auckland. We dollied the bike up, as I had entered it in the Café Racer class. Our results were outstanding as it scored a deserved second place. The bike attracted mush attention throughout the...

The Tune

The Tune

So off I went to see Brett at BRM Dyno in Paeroa who specialized in motorcycle Tuning. I had installed a power commander V as part of the kit so changes are available. It would take some time so I left it there, returning a couple days later. Brett had worked his...

Finished

Finished

Very soon I had the finished article, and WOW did she look so good and very shiny. My first start up was cautious, let her idle. The engine still needed tuning and being careful I had done no damage. However I soon noticed we had a major oil leak behind the new...

Clutch Modifications

Clutch Modifications

I now had all the main components mounted. I added heavier clutch springs to handle the extra power through the transmission without the clutch slipping. Nothing serious to dismantle I just unscrewed the bolts retaining the old springs. While it was apart I inspected...

Radiator Mistake

Radiator Mistake

A Cosmetic mistake was made when I mounted the supercharger and the bend hit the radiator. Finding nothing in the instructions I chose to grind a 20mm space off the radiator housing to fit. Big Mistake. Hooking up the inter-cooler the supercharger hoses were too...

The Dismantle

The Dismantle

  Very soon my bike looked like a skeleton.  All packed in a few boxes of parts now littering my garage.  The kit came with a good set of instructions on what to do and how to do it, make sure you read them.  All dismantling and re-assembly can be done with small...

My Journey Supercharging a Production Motorcycle

My Journey Supercharging a Production Motorcycle

Having owned and maintained motorcycles for  quite a few decades it was time for something different. Why not “supercharge” a motorcycle give it more power so the engine can really “breathe”. After much web searching  TTS Performance based in the UK revealed itself...

Chasing Curves

Chasing Curves

Settling on the seat, turning the key the bike breaks into life, lights flashing, dials spinning, electronics whirring. Then the starter button is brushed and the bike throbs with the contained fire inside the cylinders only inches from one’s knees. First gear is...
