The engine in the previous thread is also an lq4 also. Granted the power difference stock isn't a whole lot, but 1 whole point of compression increase does mean bigger numbers with aftermarket cam, intake, head work, etc. There is a big difference between 9.5:1 and 10.5:1.

Agreed. Compression makes the power.

I was thinking LQ9 for some reason...that is the engine I was discussing. My bad

Compression + headflow = woopow :smoke:

No replacement for displacement! 472 BBF 12.2 compression on a single mixer to keep the game fair! lol

If anyone's interested, look up chuckstuning or hhp on instagram/facebook. Their a local shop that pumps out some nasty n/a combos along with a ton of boosted ls setups.

I'm surprised nobody has mentioned the difference between an "inertia" dyno like a dynojet vs a load based dyno like a mustang dyno. The inertia dyno will show a significantly higher hp number than the load dyno. This is real common in the drag racing world, and the reason that you see these "500 wheel hp" camaros running 12.5 1/4 mile times.

You mean the ones people tune their civics on to pick up 100 horses?

I was only sharing with you what the engine builder who builds these all the time said to me face to face. He said he had no idea what it would be at the wheels since the jeep wasn't done yet and he didn't do too many rigs with LS's on tons and 43's prior to my build.
