I have a friend with a hemi (rated at 345hp). I have a 2004 VHO(rated at 345hp). The hemi with tune, headers, exhaust, and CAI, makes 288hp to the ground. My truck with tune, cat-back exaust, and CAI, makes 325hp to the ground. This was done the same day on the same dyno. So if you want horsepower you buy a hemi and see what you get.
the Hemi has good power but its a gas hog especially in Dodge's heavy ass pigs. Like down8 said the 6.1 makes 425 and our 6.2 makes 403 basically untuned if you think about it because everything that GM knocks down from the factory. Tuned 6.2s and ls2s are putting close to 400 to the wheels. Dont get me wrong the 6.1 hemi is a badass engine but when there are 5.3s out there making close to the same at the crank then I could care less :kthxbynow:
I do understand, I am not saying that the Hemis HP is strictly due to the heads. I suppose that I went on a tangent. I was wondering what heads, cams etc.. i could get to make more HP, but still retain mileage. I know that I need a tune, an FIPK and more freely flowing exhaust.
I would love to be able to be able to spank one of those jeep srt8. That would be sweet! At the same time I would like to be able to afford to drive my car. I am not a rich man, I just feel like the Gm products are superior in every way except stock HP. I would feel good to pull up to a stoplight next to one of those and smoke it!
