Ok so far this is what I can give you. On our dyno mule which is a stock bottom end 4.6L using our heads, intake and 270 Comp cams. The motor made a just a bit more than 400HP. Now keep in mind this is a dyno motor so it has an electric water pump, long tube headers and some other tid bits your average car may not have.
We are always running the dynos and as soon as get more numbers or graphs I will post them. Keep in mind this is early in testing.

if its hitting 400hp, you are looking at 140hp more than stock!!! thats a heck of an improvement. so in reality, you are looking at around 360rwhp roughly and with a lot of room claimed for more porting, we are looking at 400rwhp 2v's in the not so distant future. If you need a car to do some on road testing and to see what an actual car would do with your heads, let me know. i would love to have a set of these things for my car!!!

dang, i guess i missed my chance then. lol but i definatly think that we will see some pretty impressive numbers with more compression, more aggressive cams, maybe some larger primary longtubes, porting of the heads, aftermarket intake manifolds, and other things. im setting my expectations high. but i bet anything that they put down will be awesome and will be more power than anything else offered out there for our cars n/a.

porting won't give you 40rwhp on a 2v. If the motor has the heads, the intake manifold (which I would believe is also consisting of the TB/Plenum trickflow also offers), cams, LT headers, electric pump, and other stuff, that's pretty much a full bolt on motor. Still very good for a 2v, but if the heads are also ported, and its a full bolt on motor, they should see a good 380rwhp, so that would be quite impressive. I'm looking forward to seeing some dyno graphs in the future and seeing that power curve.
They are also only using comp cams 270's, which are using only .55" of lift, and these heads are supposed to support up to .6" lift on the stock bottom end. Imagine higher compression and bigger lift on a forged bottom end, I can imagine seeing 400+rwhp on the 4.6L with a stock or a 283CI displacement.
