Thanks for that

Not to worry, RRMan

The boost will be the same as yours, just putting cooler air into the engine... max RPMs will stay same as I run now. The Echo turbo runs much higher boost... necessitating forged pistons and rods.

The specialized cams have a much longer exhaust duration, which helps cooling with forced induction.

Hope you're right. I can't wait to see the intercooler setup. Could be something I'd save up to add to my supercharger.

Hi guys. It's a little time since I posted but business is good and I can honestly say the R3 supercharger conversion has exceeded all my expectations on sales. It is my number 1 conversion with now over 70 kits sold world wide. Recently we have had an issue with crank spigots working loose. This baffled us for a while as we have some early kits still going strong with just a short 10mm bolt holding everything to the crank. After some serious investigation we found our parts were too accurately machined for Triumphs interface. I.e. our crank spigot slides over the crank cam sprocket. The crank sprocket has a 28mm dia. shoulder, we made the spigot 28.02mm. This would keep the spigot concentric to the crank and slide through the outrigger bearing. what we have now found on later bikes that the crank sprocket diameter can be as big as 28.10mm. The result is that our spigot was binding up on the sprocket and not sitting back on its face. In use the spigot was fretting on the sprocket and slowly working its way back by maybe only a few thou but enough for the pulley to work loose and hence the failure. The only answer was to go to the expense of a combined sprocket and spigot, in top quality steel. This was not cheap to produce (my cost $240) But it has stopped the problem. The kit cost has not gone up in price. (the $ needs to gain some strength though to help sales in the US, or around the world for that matter). Incidently the type of cam chain used is the same as the Hayabusa but if you looked at the sprocket tooth form you wouldn't believe it. The R3's teeth are way to deep and this is probably why Triumph have had failures and revised the part (even though they still haven't got it right). So all future kits will have the new part and of course any failures now or in the future are covered by my warrentee. The new part means removing the cam cover and the camchain tensioner. THE CAMS DO NOT NEED TO BE REMOVED! With the front cylinder at tdc, you remove the cam chain tensioner and blade. There is enough slack to remove the sprocket and refit our part. If the chain jumps a tooth because of valve spring pressure you can just lift it back with your fingers. Refit the blade and tensioner. DOUBLE CHECK THE CAM TIMING. Fit the cam cover. Full instructions will be with each kit.

INTERCOOLER.

Thank you Hombre for your order and patience. The combined rad and ic cores were received today. Radiators have to flow water, intercoolers-air. So the cores are different. Our supplier has provided us with a custom 1/3 ic, 2/3 rad core. The rad core being thicker to compensate for frontal area. We have to fit the tanks on the ends and brackets for support and fans etc. We should have the prototype done next week. The plumbing in and out of the ic with be bottom and top respectively and the outlet will go under the tank as the original. We will put some cosmetic guards down the sides so it won't look so dissimilar to the OE part. It is not cheap to produce and will add about $1400 to the conversion price ( would have been less than $900 5 years ago). I hope to have bhp results before and after on the same bike if all goes well.

So there we go guys, a total update. Get your President to sort the $ out and you can all afford one in the US.

Remember the blower has a 2 year warrentee.

Ride free and fast. Richard Albans

Excellent Richard. It's good to know the cam shafts can stay in place to change out the sprocket. Really shouldn't lengthen the kit's install time much since most of the junk on top of the cam cover will be taken off for the conversion anyways. Simple matter to take off the cam cover then.

Great work you do, by the way. I can tell you put in a lot of effort into designing your products.
