Does anyone out there have a non supercharged non turbo C5 pushing over 600hp out there? anyone think i should supercharge mine at some point?

Yes, along with a lot of members here. A few ways to do it. This I how I did mine.

Sinful Thunder

im currently at 640 before the tune. i did btr stage 1 cam, new headers, had some work done to my heads got tripple springs in there as well, dual intake, double linked chain buch of little stuff and NA pushing over 600 is awesome. theres like no videos anywhere with 600+hp with no superchargers hoping to be close to 700hp to the crank at least before any forced air. car is a screamer. neig=hbors called cops last night lol

What size/type of engine do you have?

Sinful Thunder

5.7 ls1 no Z06. just the base 2004 convertible

You won't get there on a 5.7 ls1

Sinful Thunder

what you mean? what you think ill end up at after the tune? if im curently at 640.

30rpm

You had it dyno'd already?

Sinful Thunder

no dyno is tomorrow

30rpm

How do you know its at 640hp?

Sinful Thunder

3k snap-on scan tool we can adjust a lot with it but not a full tune. it tells us 640

30rpm

Ok, I thought you were asking how to get over 600

Sinful Thunder

i was kinda asking if anyone else has theirs over 600 with no forced air. no supercharger no turbo. there are 0 youtube videos with 600+hp without the forced air. so it makes it look like you 100% need 1 to get over 600. but its obvisouly not true lol since lots of people have done it i heard on this site.

High tq/hp numbers NA is expensive so it's almost always more cost effective to use forced induction

Sinful Thunder

what if i told you all the parts and work i put in the car was cheaper than just 1 forced air system???? i put under 2700 into parts. and still got a NA to 600+hp

Speedy?

Let us know the RWHP #s from the dyno, that's all that matters.
With what you mentioned, you are probably under 500 crank.

Sinful Thunder

scan tools shows 640. im guessing that is crank.

With the parts you listed, you're 200+ shy of 640. I don't know how the scan tool measures or what input it requires, but that number is far from accurate. As others have said, a dyno sheet will give you a much more accurate number.

Sinful Thunder

the work on my heads added 90 alone 45 a head tipple springs and some degree wok, not sure that the cam added brt stage 1, headers adding 28 intake adding 30, double linked chain for faster response. the scan tool shows 640 if i run it again ill get a picture of it. ill def post dyno stats. what type of video file is required for this site? wont let me upload any pictures or videos.
