Boost does not directly = hp; it all depends on the setup (as this proves). HP and torque is what stresses the engine, which is not a direct correlation to boost level between different setups. This was just an initial shake-down run from what I can tell and they were using race gas to provide a margin of safety in the initial tune; why risk blowing up the engine due to detonation? Detonation can kill an NA engine just as fast as a boosted one.

Also, as this is an engine dyno, the IC is most likely an air-to-water and they probably have some huge water resevoir (probably a 100 gallons or something) with temperature control to keep the water at a constant temperature.

If you click the link in the article to Part I, Eric explains some of the aspects of the engine dyno, including perfectly controlled environmental conditions.

 

I already did. He mentions "we don't have a cobbled together system with and intercooler wobbling all over the place" or something to that effect. I wondered if that means "no intercooler" since I did not see one in the video or some other setup.

Boost does not = power... but using a huge turbo and running low boost = low torque. They would be better off with the stock turbo at those boost pressures. If this was a "shake down" run I can understand running low boost.... sort of silly to put your shake down run on the internet without the followup runs.

Good numbers but seem normal...

 

Called a teaser? Like a movie preview? And there was some good info in there; 400 crank hp at 14.5 psi is nothing to sneeze at

 

More power= more strain on the motor.

Regardless of the boost a stock motor at 400 flywheel hp is putting more strain on it than stock.

It's not over the top but I bet that motor has a lot more in it that's just not in the video!

if boost was all it took to make hp, why even get a new turbo? the gt35 probably moves more air @ 14 psi than the stocker does @ 21+

 

was the cosworth intake on that motor?

 

No, looks to be the stock one. I think they want to push the stock parts to the limits of flow to establish a good baseline, hence the big turbo. Then install their different variations of heads and intake manifolds for comparison. My guess at least.
