What's the point of drag racing if you're limiting performance via rules and regulations? Varun Sharma gives us a rundown on the 3.3L 2100HP at 75PSI Oceania College/101 Motorsport X275 Drag Radial JZA80 Supra which runs a methanol fed Bullet Race Engineering Billet block-based 2jz engine with a best ET of 6.79s at 212mph making it the fastest Sport Compact in Australia at the time of filming at Sydney Jamboree. Discussed is the decision behind running a TH400 3 speed automatic and the lock up converter setup that is required to prevent transmission slippage as they dial the power level higher and higher. The safety a billet block offers is also touched on along with how despite the extra weight the team run a water to air intercooler setup. We also talk about some of the class limitations including the tyre size which see any loss of traction turned into an aborted run and how the old independent rear suspension setup is much more difficult to get dialled in for the drag strip along with behaving differently too. The X275 Drag Radial class sees competitors restricted by tyre and power adder sizes among other rules added and changed over the years around the use of a stock location firewall, factory roof and quarters and an emphasis on equipment that was originally produced in an OEM form or is readily available in the aftermarket. As Varun explains this, along with the use of a 1/8th mile strip at many events, helps keep the competition close and the costs lower to help ensure a healthy field of competitors. 0:00 - Introduction 0:49 - Why A Restricted Class? 1:46 - How Limiting are 275 Radials 3:12 - What Is Controlled? 3:58 - Chassis Setup 5:27 - IRS vs Live Axle Rear 7:31 - Supra Setup 8:12 - Water To Air Intercooling 10:09 - Bullet Billet Block 12:03 - Why Billet? 13:04 - Transmission 14:28 - Lock Up Converter 17:35 - Outro Want to learn how to tune EFI?
