When having a turbo malfunction goes right

Great article.

How a Broken Turbo Gave this Nissan 1000+ Horsepower and Nearly Set a Speed Record

Entering the 1990 race with the new Mulsanne chicanes installed, the concept of massive top speeds was quickly forgotten—a thing of the past. Well, at least until Blundell strapped into his No. 24 Nissan, engaged first gear, and pulled onto the circuit.

It was here, as the Briton describes in full audio detail below, where malfunctioning turbo wastegates ensured the R90CK shot past the 1000 hp mark—to a maximum figure that is still unknown—and snapped his head back with every upshift.

The Nissan's raging twin-turbo V8, oblivious to the constraints of time and space, launched Blundell down the new stop-start Mulsanne sections at an incredible 238 mph. Imagine what the number would have been without the chicanes. Faced with the same Mulsanne chicanes, the best top speed from the 2016 event went to Audi and its hybrid R18 turbodiesel: 213.4 mph.

That is an incredible amount of speed. I am also surprised the engine didn't let go. Makes you wonder what these cars and engines are capable if they were allowed to be put on full power for a lap or two.

Yeah, how over-engineered was that car.

Engine Master's did an E-Bay turbo kit build, and I one of the problems they had was the waste gate was not sufficient for the build, or didn't work right. So the engine built MAD amounts of boost, and survived, for a while anyways.

Many of those Ebay kits use sub-par wastegates. Not only too small but bad quility. Plus the design of the hotside and wastegate position is less than ideal. But those kits are better than they were years ago. The turbos and hotside are horrible. Put on a good wastegate and modify the kit some and you have an ok kit for a cheap build.

Pretty sure that car had a better quality set up than your average eBay turbo build

Was probably pieced together off Craigslist...lol

That is flying considering the record was 253 before the chicanes where installed and the car only lasted 53 laps after that.
