Freddy aka Tavarish on his YouTube channel sometimes shows what not to do when fitting and driving supercars. Freddy regularly repairs and rebuilds cars on his channel, so it’s only fitting that he now has one more car to add to his rebuild list. Unfortunately, this time it turns out to be quite an expensive project, as it details the extensive damage caused to its 2016. McLaren Engine 675LT.
Not only does Freddy blow up the engine, he destroys the entire bottom end. After showing the incident that ultimately spells the end of this particular 4.0-liter twin-turbo V8, Freddy rolls the poor McLaren into the shop to see the full extent of the damage up close and personal.
The 800hp McLaren 675LT has too much power for the stock in-house engines
Freddy is driving with his friend filming when he hears loud noises and smoke starts coming out of the engine compartment. Stepping out of the beautiful 2016 McLaren 675LT in bright blue with gold trim, Freddy looks annoyed at the huge puddle of oil under the mid-mounted engine.
Freddy is the first to admit that he may have been too aggressive with his latest tune on this McLaren 675LT. It increased over 100 HP from the stock 675 HP. He also notes that the McLaren block can handle around 600 lb-ft of torque, and lets out a grin when he says he may have surpassed that number.
Ultimately, the internals of the stock casting engine no longer whined. Although lighter than their forged counterparts, the internal sand cast components sacrifice strength. Freddy explains that the McLaren 675LT engine is light and built to allow high RPM, hence the engineering choice for cast internals.
The broken rod in the McLaren 675LT breaks the engine
Freddy rolls the McLaren 675LT into the shop and once on the lift, details the actual damage to the engine block. Huge chunks of engine parts and bits of metal are left loose in the tray as he pulls it out of the car. Shining your flashlight on the engine itself reveals a huge hole in the bottom of the block.
Freddy examines the inside of the block and concludes that he blew off a connecting rod which led to a chain of other massively destructive events. With the entire bottom end unsalvageable, he asks his friend Kevin from Supercar Garage for an appraisal.
Kevin explains that Freddy is looking at over $100,000 total to get and replace his McLaren 675LT engine. Freddy concludes that it might be wise to build the new engine for reliability before installing the performance tune.
