To add, this was done on a completely 100% untouched f20c w/ 125,000 miles running 22psi.

EDIT: FIXED VIDEO AND ADDED DYNO CHART

 

this is why Steve does all my tuning

 

That is sick David. I heard that they could make a lot of power but I always assumed it was always by replacing some internals. 600whp is simply sick!!

Bottom end on the S2K is forged already. A thicker head gasket usually does the trick.

I would've kept mine if I didn't live here.

 

Yea Carlos, its pretty stout stock. Open deck block design too so people shouldnt worry too much about the semi closed 4b11t The 601whp is on a dyno dynamics which reads really low too! I still find it hard to believe considering the almost 11:1 compression ratio lol. It made 518whp on 93 octane.

 

Impressive! I've heard it done as a local shop in GA pumped out 631, but kept on breaking rear diffs.

 

holy crap!? i never thought id be impressed by a honda in my life!

 

Just realized the video link wasnt working... fixed it
