Modified Magazine, Import Tuner, Super Street, Turbo, Sport Compact Car, EuroTuner and Lowrider are set to square off in a no holds- barred engine build-off - the Castrol Top Shop Challenge. Each magazine has teamed up with a shop and chosen an engine. The goal is to build a motor that will outlast, outmuscle and outrival the competitors in the following categories:
-Best peak horsepower and torque per liter of displacement. Forced induction engines will be given a multiplier of two to level the playing field against the naturally aspirated engines. (e.g., a 2.0-liter 4G63 engine will be judged as a 4.0-liter engine.)
-Power under the curve. An engine that produces a broad range of power rather than big peak numbers will be rewarded in this category.
-30-minute drive cycle. Engines will be tested on their longevity and build quality.
-Build quality/craftsmanship (judged by a panel of three experts). It's not all about the numbers. The best engineered and executed engine will win this category.
The rules are simple. Only production engines found in production-based cars will be allowed. Only one forced induction system per car will be permitted (either a turbo or a supercharger - but not both). The fuel is limited to 100 octane. No additives, methanol, auxiliary fuel or water injection is allowed. The rest is fair game! The final testing will be done on one engine dyno. Teams will have the ability to fine tune their engines before the official runs are made.
The rules for the Castrol Top Shop Challenge are wide open, so the competition will be fierce. Luckily, we've got arguably the best tuning shop in the nation on our side - AMS. Considering their extensive knowledge and R&D of the 4G63 engine, deciding what motor we would build really was a no-brainer. We're not going to give up our secrets just yet, though. Expect to see some tricks up our sleeves, because it's going to take more brains than power to win this competition. In the coming months we'll give you updates on the competition and the goods on how we plan to out build them all.
