Tecklenburg, Mazworx Fire Up Wild Triple-Turbo Celica

Born out of a pit-side conversation, this wild triple turbocharger, compound-boost, power-adder system is the brainchild of tuner extraordinaire Shane Tecklenburg (Tuned By Shane T), who was asked what the craziest thing was that he could think of to try to make the race car he was tuning at that moment, quicker and faster.

“Team Tekno Toyz had been running a single-turbo SR20 in Modified Compact and Pro Import 4 cylinder categories at Orlando and Maryland,” Tecklenburg begins. “I started with them around 2017, worked on the car little by little, and at the end of that season, we were up in Maryland and another friend of mine, Ralphie Navarro, who I’ve done some land speed racing with and who’s into motorcycles, was there and hung out with the team. He stayed with us the whole weekend. We were having a few beers after qualifying and he says, ‘What’s the craziest thing you could think of to try with one of these cars?’ I told him I would put a compound turbo in one of these (referring to the SR20 in the Team TeknoToyz S15) and put it in the fives. Everyone laughed, and I notice Ralphie over there in deep thought and then he asks, ‘What do you think it would take to do that?’ ”

Tuesday after the race, Navarro contacted Tecklenburg and asked him if he was serious, and if so, what would it take funding-wise to accomplish that goal. The money was wired the next day and Tecklenburg got a duplicate single-turbo SR20 engine build going with Mark Mazurowski/Mazworx Racing Engines in Sanford, Florida, who assembled the billet block and added one of its race-ported, stock head castings. The original single-turbo engine combination was designed with a 10:1 compression ratio, which Tecklenburg and Mazurowski decided to carry over to the compound version.

JT Oliver was tasked with fabricating the compound turbo system, which was designed to bolt onto the single-turbo setup and feeds the single Precision Pro Mod XPR 88m turbocharger on Matt Scranton’s engine dyno. He also incorporated two TiAL wastegates on the high pressure side and one for each of the low-pressure turbos, all in an effort to go prove the concept on the engine dyno before it was put to use in a car.

“The two [turbos] on the front are Xona Rotor 88mm compressors with a smaller GT42 exhaust side, because we are splitting the exhaust flow to the Stage 1 Turbines and that will help get them to spool at the right time,” Tecklenburg explains….
