BC4 didn't make 330hp, there's nothing they added to them to do that.

As for factory freaks, I have no belief for them

not such a thing as a factory freak your guys cars were made with the same as mine, they didnt accidently throw a set of roller rocker or headers on a car from the factory, lots of people like to claim factory freaks or stuff like that then they start modding and find out oh this this and this was already done.

There is a possibility in the head making process that they are slightly different. There is no way for them to make every single head or intake absolutely identical, there could be less material here or less there, true engines are identical, but where do you make power?...heads, if they are slightly different you could see slight differences in power.

You guys have to remember where some of these guys with "freaks" are racing. They are generally racing close to sea level with very low (and sometimes negative) DAs. You won't find a LT1 trapping 105-106 here with intake/catback. It takes headers to trap that here...where the same car might trap 108-109 somewhere else.

True, but dyno numbers would be SAE corrected. I felt my car was strong as it dyno'd 260 rwhp with only a muffler. Not even a full catback. Jordon's car had 266 with catback, gears, and a CAI. My car only went 101, his went 105. I'm sure weight played a part in that tho, as I weigh 385, and unless Jordon is made of lead, he can't be anywhere near that. A local guy around here has a BONE-STOCK 97 and it dyno'd 277 SAE. I thought that was crazy.

Maybe I'm off my rocker, but I think a LOT of people have their cars tuned wrong (not just programming tuning). Does a hot cam car really only make 325 rwhp roughly? If so, its not worth the time. I've compared my dyno sheet to more than a few hotcam cars and they have less power everywhere until about 5200 rpms. Maybe its in the fuel injection, maybe its in the opti, but there should be more power in a lot of the cars on the forum.

Some people call mine a freak...but I don't think so.

My friend has a 1993 Formula with Loudmouth and a cheap CAI, and went 13.1 at 105. Definitely the fastest bolt-on car I've ever seen...especially with under $450 in modification.

The fact that dyno numbers are SAE corrected means you could dyno 266 rwhp with say a 1.07 CF...that means you would only be putting down much less than 266 uncorrected rwhp in the "real world." I think if everyone corrected their ET/MPHs, there wouldn't be as many "freak" cars out there. However, this has it's limitations. My car, corrected for 4800' DA runs a high 11 at around 117 mph. Will it ever do that on this setup, hell no.

I see what you're saying about the dyno v. real world, however, if your car dyno's 335 sae and my car dyno's 300 sae, and we raced on the same day in the same location, your car is faster right? However, if your car dyno'd 309 STD in high altitude humid day and I dyno'd mine 311 STD with say a -450 DA, and we then raced, again, in the same place, same day, regardless of current conditions, my car is NOT going to be faster than yours. That's why there is a correction factor - to compare, not race. Also, I've never raced someone over long distances, i.e. me in SC other in AZ or whatnot. Usually you start right next to eachother.
