I've seen it all now!

Anyone fancy blowing up their engine for £400?

That's a lot of money for a 12v hair dryer

I’d need two though, one for each bank.
Would that double the power increase?

At least 10 years ago there was a chap in the TR magazine who put together a beautifully engineered and finished supercharged TR6. His initial experiments (I think to see if any increase in power) started with a heater fan, some tubing and a big relay. It worked but didn't last, but I don't think he expected it to - it was just a lash up to see if it could be done.

I think he ended up with a unit from a Mercedes Kompressor.

A pal and I lashed up a turbo from a Ford on a Mini 'A' series engine. It went like stink until the turbo oil seal failed!!

For reference,-
The GT6 turbo project worked.
The 2.2L engine made 380bhp, with the nitrous on, so don't say it can't when it can!

It started to snake at 120mph!!

I finally opted for smaller bores in the thing, cos the large bore engine used to knacker head gaskets.
As far as I am aware that's by far and away the most highly tuned real triumph motor ever done.

I wish I could find the article, Gareth. I remember it was very bright red and I think he claimed a little over 220 BHP. I also recall that he had an engine management system and had dialled back the possible advance as well as the amount of forced induction, rather than risk throwing a rod or blowing a hole in a piston. I am pretty sure he red lined it at about 5000 as well in the interests of engine preservation.

I have heard anecdotes of huge increases in power and torque via this method which didn't survive the test drive. I think a lot of people don't consider the additional force unleashed which is kind of my original point.

I supplied the pistons for that engine (they were made from Cosworth blanks) so the chances of holing a piston were absolutely NIL.
The fact is it became very hard to measure the power output as 220bhp was at only 5000rpm without nitrous, whereas the thing leapt off at 6000+, and then started to snake wildly when the nitrous came on.

The main reason he opted eventually for YB Cosworth engine, is quite simply - you can get more than double that dead easy and it's 4v per cylinder with a modern alloy coscast head, rather then an ancient lump of iron made by a cutlery manufacturer in Sheffield (Bilchrome).
