From what I can remember they have ten something to one compression and my question is what will people use to significantly increase horsepower? It seems the only way to go will be nitrous and the coyote engine seems like it wouldn't respong all that well to bolt on's because it seems like they've squeezed every last bit of power out of it they can from the factory.

people will use boost because the engine is perfectly capable of handling it. people will also use bolt ons, because evo has already made 415RWHP over a stock 385RWHP(IIRC) with the basics. the sauce is already being used.

How much boost can it take though? It seems with its higher compression it would need race gas.

You will be able to run enough boost to overwhelm the connecting rods. Detonation will not be the limiting factor on power, internal strength will be.

It will handle 8psi on pump gas with stock compression.

Oh, and it's 11:1 not ten something.

The early cars (live Evolutions) are gaining 40 HP from the early bolt-ons (375 to 414). Over time, there will no doubt be more unleased.

This "maxed out from the factory" garbage was internet rumor that detractors started. Only time will tell, but it appears this engine may make just as much "bolt-on" power as GM's LS3.

i wouldn't quite say that detractors started it, because i was certainly assuming that this thing wouldn't gain much from bolt ons, lol. it really is amazing how capable this engine is though, i mean it shouldn't have this much left considering its factory HP/l, lol.

Even though i hate to say it. that is not true
the ls3 has the displacment advantage. 5.0 to 6.3

the ls3 will benefit more from bolt ons. in the end.

the coyote has FAR better flowing heads, as well as the twin variable cam timing. while it probably won't erase the displacement advantage altogether, it will certainly help to minimize it.

I think not...from ownership. more cubes but old technology. my ls3 did 384 with a tune and a intake- EVO stock 2011 made 385 stock..... then i made 410/409 with LTs intake and tune EVO did over 400rwhp with a drop in KN mid pipe and cat back with no headers:rockon:

good point

good point as well.

seems like most ls3s are in the 370-385 range stock.

Yeah, I felt all alone those days lol. Check my posts from about 6 months ago, you'll see what I mean. ;-)

where have you been? its 11:1. and so far the cars dyno 365-378rwhp stock and bolt ons have yielded 414rwhp. please update your facts. no offense.

look fellas. if two engines use the same heads with exactly the same compression the larger engine will simply make exactly the same hp at a lower rpm. if the coyote heads outflow the LS-3 heads, and have cams to take advantage, as well as rev high enough, they will make more hp.

everyone was arguing that a 5.4 2v could not make more power than a 4.6 2v, and now suddenly cubes are god. even though the smaller motor has better heads.

I see most dynoing in the 360s stock

Don't tell many CF LS3 owners that ;-) You would swear all LS3's dyno 390rwhp SAE and run high 11's bone stock, all of em! The new 5.0 dyno's higher and easily achieves more power with simple bolt-ons than the LS2. My C6 made 410rwhp/407rwtq SAE with a cai, Vararam, FAST, 1.85 rockers, full-exhaust (1 3/4" long-tubes & cat-back) and tune.

Was that on a Mustang dyno? 384 w/ intake & tune seems a bit anemic. These are numbers I typically see out of a stock LS3.
