SuperCharger

[AMSQ3D]

Has anyone ever fitted a Triumph straight 6 fitted with a supercharger.

[Nick Jones]

It's been done

Here's one: http://home.mchsi.com/~downersteve/wsb/html/view.cgi-about.html-.html

Reported to make 230bhp but bearing life v short!

And some turbo ones: http://www.turbo-tr6.info/

And Josh Bowlers supercharged Spit: http://www.bowler.fslife.co.uk/triumph%20spitfire%20supercharged.htm

'gt6 user and abuser' is currently going through this process aswell

There's a few blown sixes here too http://triumphs.50megs.com/blower.htm always fancied a blower myself, one day I'll do it - in a 2000 or maybe even a Stag :-)

[Nick Jones]

I've thought about it too - but space is a real problem under a Vitesse Bonnet - you could get the supercharger itself in but nowhere for and intercooler/chargecooler - and you'd just bust the rest of the drivetrain.....

.....whereas a Triumph 2000 engine bay is mahooosive if you move the battery :-) The drive train i s also very tough and can be beefed up a bit of you are going to be brutal - whicj of course you must!

My dream car! Mk1 2 litre with a supercharger.... imagine the noise!

High pitched Witor wail with the supercharger whining away...

Fora while I toyed with the idea of dropping an old Marshall blower into Karen's Mk1 2000. That was a big supercharger, too big for the engine capacity, but there was just enough physical clearance to get it in with all it's plumbing. A more sensibly sized blower should go in easily enough,

Stop it Bill... you're making me make whistling noises as I walk around the house...

The problem with superchargers is they are a lousy inefficient way to get power..contrary to belief!

In the case of the Range Rover sport (Jaguar XJR) the Eaton blower is the biggest culprit.

The darn thing uses a GOOD 70+bhp to drive at peak revs, and that translates into collossal pumping inefficiencies and heat generation- which means HUGE fuel consumption.

The only decent car I ever saw with a supercharger installation was the G60, but again we had to vent the bonnet to get the charge temp down, - no easy job, and it still had massive fuel consumption.
In that car we added nitrous and that brings temp down to a more realistic 30-50C,- so you then get SERIOUS torque.
Nitrous of course is not cheap (per fill) so still makes a nonsense of the current fashion for superchargers as against turbos, which are inherently far more efficient devices.

There is a better solution to the Eaton/Rootes type vane/Lobe blowers, but these are patented in Sweden from Lysholm

Such a screw type, brings charge temperature down about 20C and has a power saving of about 30-40%.
So you see how the motor industry sold us out yet another stupid outdated system in the last 10 years, while the superior products again got sidelined mostly for commercial reasons!

70 bhp!?
I think you have calculated wrong!

Supercharger's.

Have you seen under the bonnet of a SL55 S55/E55 AMG Mercedes's.

Mercedes bought the Kompresser to us in the early day's and have made it far better than most people think.

I'm not bias I work on these car's for a living.

The big ones certainly do take up a lot of power...

For something the size you'd fit to a Triumph - it says 25bhp - which on a stock Spitfire is 1/3 of the engine power to begin with!

Always dreamed of a blower - one day it will be mine, oh yes. They do make a lovely noise but I do want to keep it all inside the bodywork and looking standard ish - a Q car :-) Not like my mate Chris This was with the "old" 9 litre - it's got a bigger blower on it now!
