I have always wanted to supercharge a car, so I fitted one to my mk3 Triumph Spitfire |
|
| here are
some of the ingredients
what you see is a BMW mini cooper Eaton M45 supercharger with a bit of the pulley tensioner, and my homemade adapter plates. A modified Jackson racing outlet pipe with the mini bypass valve fitted to the back. A Vauxhall rascal mini van alternator, a custom made crank pulley, a pace 3 core charge cooler, Volvo 480 electric water pump to flow water around the charge cooler and a Toyota supra oil cooler to cool the water! |
The pulley is based around an early triumph 1300fwd crank pulley with the billet charger pulley bolted to it |
|
The fuel is delivered by 2 Dellorto DHLA 45m turbo carbs which were fitted to the Lotus Esprit turbo |
 Fuel is delivered by this Facet 20psi fuel pump and is controlled by a boost sensitive regulator, a fuel return line back to the fuel tank needed to be added for this. the fuel pressure always needs to be mores than the boost pressure otherwise it will get blown back into the tank! |
 Here is a test fitting on a dummy engine, the tensioner shock absorber is from a mountain bike, the spring is from a VW G60 tensioner |
 Here you can see the the charger and pulley during the installation process |
 Above you can see the installation from the carb side.... |
 And here it is from the supercharger side, |
| The install took about a day, collecting and making the bits up took considerably longer! I imagine I will be fiddling with jetting for a while, With the bypass valve I am able to limit the psi, it will boost up to 11psi if I let it! I have set it at 5psi for day to day motoring. 1st impressions... its a lot quicker than before with a totally different power curve and LOTS more torque. I need to fit a blow off valve as I get pressure spikes when taking my foot off the accelerator pedal. | |
