Hyundai IONIQ land speed record

On November 2, 2016, a modified production IONIQ set an FIA speed record, at 157.825 mph at Bonneville.
* nose was tweaked
* airdam was extended
* wiper delete
* some gaps taped
* air curtains sealed off
* mirror-delete
* lowered
* belly mods
* MOONs
* Goodyear EAGLE racing tires
It's fascinating that, again, when the reputation of the corporation is at stake, the convex, full disc, wheel covers are preferred, and the drag-reducing air curtains are abandoned.
It's an easy GOGGLE. Some nice high-res photos.

Running on Goodyears wasn't a bad idea just a day ago.

My guess is, that Toyota engineered all the engine components for a limited BMEP, and adding extra atmosphere sent it over that threshold.
In the Prius, the electric motor assist is equivalent to the nitrous injection. Pistons, con-rods, and crank journals never feel a thing.

Your guess is (as I am afraid is very often the case here) quite wrong. I supercharged - and then turbocharged - a Prius over 15 years ago and the engine coped without any worry at all.

Did you operate at W.O.T., continuously, for 12-miles ? What was the difference in B.M.E.P.?

Your search term is https://duckduckgo.com/?q=autospeed+turbo+prius&ia=web

There may be a summary page, there're 55 pages of feature cars maybe it's in there.

This is typical Aerohead. Completely wrong, so changes the proposition of the argument.

You said:

You are wrong. But rather than recognise that, now it becomes:

No I didn't, and that is not what was required to prove that your point was quite wrong.

The car didn't go on a dyno, but BMEP would have been up considerably - I ran highest boost at peak torque.

All in all, a good example of Aerohead's posts - about half are are wrong, misleading or irrelevant.
