The heated sprayer on my Century/Ninja extractor is also 200 psi, but IMO it wouldn't be of any real help with engine bays. If you want something along those lines that's potent, use a pressure washer or a steamer. I'm not gonna be using my extractor for engine compartments, simply not the right tool for the job IMO.
But hey, I've never tried it either, I could be completely wrong
