Fully this. Technology/development has come such a long way in the last few years. Making '1000hp' is much easier than it used to be. Fact is people expect a lot from built engines and they are pushed to the limit. Guess what, they break. They all do. After you have sunk 30k, 40k, 50k (and the rest) and you have a failure, it all becomes very hush hush. People only see the timeslip and ridiculous MPH and think wow. what a street car, when in fact they have lunched multiple engines to get there or have spent another fortune chasing that tenth.
Any of these high powered cars are very much not street cars despite what people portray on so social media. Driving it to work once then doing highway pulls on the odd saturday night does not make it a street car. It's a race car with rego plates. If a highway patrol pulled you over, youd be f**ked.
Get a billet block, fill it with expensive gear and send 70psi through it. Please tell us how it goes.
