We purchased a good, running 16k mile take-out engine from a 2010 Taurus SHO for engine development. This will lead to some exciting things...

I was going to document the entire tear-down, unfortunately the guys in engine build got excited to see what was inside..

Interesting!

Rick, I've noticed the the 3.7 NA engine has a much higher rpm range and higher NA power level vs the 3.5 EB. I surmise that the camshafts are a large part of the difference. Is there any chance of retrofitting 3.7 cams into the EB, or does the HPFP drive make that impossible? It could be worth 40+ hp, if my math is correct.

Very nice. Keep us posted of any developments.

Seems like a lot of carbon on that piston for only 16k miles. Even down past the second ring. Yikes

N/A hp is largely due to the compression ratio. If the ecoboost didnt have turbos it would be a turd. But cam profiles etc do come into play of course too.

The 3.7 and 3.5 aren't even a point different in SCR. DCR and cam profile are way more important these days.

Actually all the power in a motor really starts with the cam... Compression ratio kind of compliments it.

Forced induction motors really don't need the same style of cam as a naturally aspirated engine since its forcing air in... Sure you could likely improve on it but if you're going through that trouble then why not just go bigger turbo.

As the others said. Half a point of compression is about 2% hp - basically less than 10 hp. However, if the 3.5 EB were naturally aspirated, it would be in the 250 hp range. It's missing over 50 hp.
