Yep from 5th Gear last night the VW Golf 1.4 with both a supercharger and a turbocharger. I loved the way at the end of the segment VB-H man/lady said "and now you know all about them" when they had actually explained dick all. I would have liked them to have got quite a lot more technical.

Does your average 'company car allowance' type NEED to know how it works? No. They just need to know it is there, and that it is good, so they can bray loudly about it to their mates in the next 'management booze-up'. Motoring-lite, for those who wouldn't be seen dead in anything that wasn't silver and more than 3 years old...  |

I spotted that they didnt explain anything about them as well - so I had to then bore the missus with a 5 min expalanation on the difference between the 2.
Why has it taken this long to use the 2 together, when the 037 Lancia was doing it back in the early 80's.
no doubt in 5-6 years time, when the barry boys get their hands on the golf - they will be chipping them to the max .............350bhp from a 1400cc or something daft - resulting in lots of blown up motors 100 miles after fitment.
no doubt this little golf will end up a retro classic in time.

watch this space dudes after xmas I should be in my twin charged imp, check out page 64 in the new retro cars mag (pic is pre supercharger mounting)

Why so secretive? Its not like its some new undiscovered form of propulsion set to take over the world!

I've actually been running through the possibilities in my head for a fantasy car monster using all the bits I've seen on cars I've owned.
Skoda Estelle (I like the 4 doors)
Skoda Rapid 135 RiC (low compression early injection with electronic ignition) engine.
Mini Cooper S Supercharger
Toyota CT26 twin entry (from the UK/US model not the J import) ST185 GT4
Magnetic clutch from an aircon compressor
boost pressure swich similar to the overboost limiter in a Saab 900, basically a hobbes switch reach a certain boost level and it cuts an electrical signal.
Revs based cutoff switch.
Set of GSXR750 throttle bodies on flanges bolted to DCOE manifolds for the Rapid with a nice big carbon fibre plenum.
Megasquirt'n'spark-extra
Mount the turbo onto the standard exhaust manifold Blow into the supercharger.
Use the Hobbes switch , rev switch and the mag clutch to control whether the supercharger is huffing. If boost is lower than X PSI or revs below Y revs (when the turbo reaches spool up) run the supercharger, else the disconnect the belt by removing the current to the magnetic clutch.
Maybe even have a play at sticking bigger injectors and a decent fuel pump in, and create myself some ethanol from brewing horse feed and triple distilling it. higher octane but needs more because it is a lower calorific value (like running LPG) but it doesn't eat fuel system parts like methanol does.

you need more ethanol because the stoich ratio is about 40% lower than with petrol, so instead of 14.7:1 air fuel, you need about 9:1.
Got a load of interesting bumpf on it if youd be interested?
Oh and it sounds like an ace idea for a car!

Oh and it sounds like an ace idea for a car! J I've found a few US sites about doing it, especially to carbed cars. But yeah any info would be cool. I think I better A) get a job first B) find a workshop/lockup C) find the right car then learn to break it. D) learn to solder to build the 'squirt. |

The guy from a well-known west london engine builders (he told me it was all top secret) was telling me about this engine he was building for a MINI racer that added the turbo to the supercharger. It had cost a fortune to develop, and just the valve to switch between the two was about £1500.
One of the main reasons they'd done it was because the car was used in endurance racing and they'd had turbo failures and supercharger failures so this was actually capable of running on one or the other or both, which I thought was a bit clever.

£1500  someone got ripped off! A twin charging system can be developed for not too much moolah, then again a bit of lateral thinking goes a long way. If you just want it and have money then i guess you have to pay for lateral thinking! J |

It may be possible to use a changeover valve from a twin-stage turbo application? Like a PSA 2.2 or the new land-rover V8 diesel. Saying that, I can't imagine one of those valves will be super- cheap.
