Seat Leon 421Ps

The supercharged Leon is one of our favorite children, for they are popular, powerful, and can easily become even more powerful. With additional effort and sufficient know-how, they can be transformed into true "Kings of the Road." The omnipotent Leon is one of the most recent powerful examples of our work.

John, the owner of the almighty Leon is crazy about his four wheels with the powerful engine. Known by its nickname "E'Lui" ('and him', as the Italians say), it made its presence known at the last Drift Challenge me the SEAT Leon.

He stated to Power Techniques:
"When you go to a dance, you dance .I couldn't leave it untouched, but I didn't expect to wind up with a monster. When on the other hand, on the road you see a horsepower reading rise together with an adrenalin rush which ever increases with every touch to the gas pedal, you become dulcified. You can't get it out of your head and you always ask for more.Good for Lambros! He managed just fine, and now there are only a few details left. We believe that we have the best Leon on the Greek streets , and one test drive will convince you". . .

At the rear part of the motor, a large Garret is in command, supported in a tubular mollusk . It's made of fireproof stainless steel, designed and manufactured by Stratis Autosport particularly for the powerful 1800 model with large turbos. There is a special place for the external American Tial wastegate, having a diameter of 40mm, and it's "puddened" with a thermo-insulated DEI exhaust wrap. In this manner, the temperature of the engine compartment is kept at reasonable levels (not just for application, but for the season as well); and the turbo is assisted in making the fewest revolutions possible.

The remainder of the exhaust system, with its competitive metallic catalytic converter and two independent boilers, are constructed similarly of stainless steel by Stavros Skrivanos of Neos Kosmos. The same is true for the turbo tubings which send air to the huge front mounted Sparco intercooler (which with dimensions of 45 x 56 x 7, takes up all of the space between the bumpers and the air conditioning cooling unit); and directs the air to the 65mm damper, patented by Stratis AutoSport. As seen in the photo, all of the elastic connections are effected by a SAMCO silicone collar. The disengagement of breathing neither stops at the damper nor at the HKS "mushroom" funnel. Since the cylinder head improved, and the manifold introduction was modified in order to apply perfectly to its well-bred pipes.

A competitive ??? fuel pump has been installed in the SEAT with an output of 260lt/hr and competitive fuel injection nozzles registering 520cc/min. For extra security, we use Jackson Racing's water injection, with nozzles of 0,6mm and pressurized valves. Once the 0,6 bar is passed, the intake pipe fills with fog! The pyrometer doesn't ever pass 900, independent of the amount of pressure placed upon the engine. In all, there has been a major undertaking to ensure the safety of the engine.

Everything has been lightened with the exception of the crankcase. Unorthodox Racing provides the engine block kit for the crankcase, the generator, the water pump and power steering. They are made of aluminum, perfectly balanced, and the whole set weighs 620gr, while the factory's exceed 2,4kg! And Unorthodox's aluminum steering wheel weighs only 5,5 Kgr compared with the factory's 11,8 clump of a wheel.

The low boost is 1,2bar and its owner chooses it mainly for city driving. In serious situations, the pressure is elevates to 1,8bar. While the car has capability of operating over 2bar, that probably won't happen. As its owner says, "With whom would I use it? I'm already leaving them in the dust at 1,8!"

The pistons are made by Arias of normal diametrical dimensions for powerful motors, and the Pauter connecting rods are made of drop-forged steel, imported by Stratis Autosport. With competition flanges, we have 9:1 compression, and the car burns super unleaded gasoline without any problem at 1,8.

Superchips is responsible for the fantastic work that has been done on the computer, the best work of all being the attempt to produce a software program for this car - without halts or hesitations, or a conceivable "safe mode". In other words, a perfect software program for a perfect automobile.

The LEON in action proves to be a supercar .

The result? We should have been placed side by side with other models, so we could say we have a true competitor. The LEON goes head to head with automobiles like a 360 Modena or a Carrera GT3 ! The 0-60 km/h runs in just 2,39 seconds, and the 0-100 km/h runs in just 4,43 seconds. The LEON continues headlong, and in 10,09 seconds from a dead start reaches a speed of 160km/h, matching that of a Ferrari and a Porsche. It reaches 200 km/h in just 15,94 seconds! The LEON did the Dragster 400 in 12,73 seconds, exiting at 178,95 km/h.


Greek Power Techniques' test of the Audi was impressive in its performance and demonstration of raw power. Its power measurements registered as follows:

All tests where done with 2 persons in the car and a half full gas tank

Significant editorial comments:

-"On steep downgrades, the automobile is very neutral, reacts immediately to steering, and holds a steady course even when the gas pedal is floored. Of course the Haldex helps (which can be felt morning, noon , and night not only with its double horsepower which

SEAT determined for this car), but the car is fixed to run virtually on its own. It banks minimally, only when necessary to avoid unwanted slippage by the driver, who nevertheless retains the right to play a bit with the rear end, tapping the brakes, making the car's "nose" angle a bit with a light touch of the steering wheel. It's wise, to be sure, to first deactivate the electronic monitor ESP.

On closed tracks, the car challenges you to react quickly. The adhesion of P. Zero Nero is very high along a longitudinal and transverse axis, but with properly dispensed and timely use of the gas pedal, the car's tail end can be turned delightfully. What's needed is a soft touch, especially when the road is slippery, because up until the Haldex senses what's up, and until it can balance the heavy chassis, the LEON slides on all four wheels. But at higher speeds, as we found out afterwards on the national highway, the automobile behaves very well. It neither clatters nor bounces under various irregular conditions, even on long trips. The 225/40-18 read the road, but not in an annoying way, but for one thing increases the information from the steering and the suspension. In fast road extensions, the automobile inspires confidence, and won't scare the driver if he should suddenly run into a strong side wind or an unusual spin during a turn.

-"The times are beyond any doubt. Let's not forget that the LEON with its 18cc engine, its 1.440 kg weight, its almost full gas tank and two passengers, is a road car for daily use, not a thoroughbred machine for drag racing. In spite of its amazing performance ratings, it retains sufficient homogeneity, advanced features and predictability, while remaining flawless in its friendly responses, whether in a city intersection gridlock situation or ???? ????? . Need we say more?
