Wow, look at the curve difference indeed. Also look at the rpms. Just as some have said. The stock heads/intake kill the upper rpm power.
What would you do H/C/I or Vortech.

That graph for sure has a more flat and stable torque curve than mine, but at 2,500 RPMs I already make more torque, and you tell me with 20 more horsies that that combo wins? I think not. The stock heads and intake definately bottleneck the potential that a supercharger gives. If you ask me do the S/C first and get the extra few horsies and enjoy them, then do the H/C/I in the future. If you don't change your parts in the future you will end up at the same result whatever you start with, so why not start with the one that gives you more power?

I'm kinda in the same predicament with my engine choices. I am building a 331 for my cobra and contemplating on whether I should go SC. I agree with what was said that a superchargers potential is not optimized on stock heads/intake. I would start with a solid shortblock, good flowing heads, good intake, and a cam choice that supports your H/C/I combo now and a supercharger in case your brother decides to get one in the future. Good luck with the project.

I thought the exact same thing when I saw the comparison of the two pulls.
First of all ... You have to be careful when you compare pulls.
I just hate it when you see a pull where the hp & tq are scaled differently. It can make the curves look less than what they really are.
As you pointed out ... look at the value at 2500. 2750, and 3000 AND be sure you get your tq values from the RIGHT side of the chart. You'll quickly see the blower is producing more tq.
What needs to be done is put the two on an equal visual kinda thing by loading up each of them using the same hp/tq scale.
I ain't gonna do it as its a lotta work unless you got the numerical hp/tq values.
anyway .......
I don't feel there is an issue of your dyno results or my dyno results winning or loosing.
Both combos have their strong/weak points.
At this point in time, at least for me, if I did it again ......
I'd go blower first but it would be KB
It's all good and I'm sure you're having lots of fun

LOL ... having gone the KB route, I'm now thinking I'd go HCI first on my daily driver. Heh, wanna trade cars?final5-0 said:
I guess the grass is still greener on the other side.
Then again, if i had a 4.6 (either 2v or 4v), I'd probably stick with the KB because that version of the KB is intercooled.

For someone that already has an intake.... sure makes me drool to get that much more power down low, knowing I would be part way there to get the additional upper rpm range bonus.

heh, did i mention mine is for sale?gcomfx.com said:The KB route also gets rid of the excuse about the stock intake.

Nope.... and I can't hear you! 
I'm trying to do the right thing and buy a new DD before I add to the stang.

the vortech would be the way i would go.. if he just wants to bolt it on and go.. it comes as a kit.. with all the needed parts.. timing retard very much needed for the blower.. the fmu.. but if he wants to get the maximum performance out of the vortech he should get it custom tuned and run bigger injectors and mass air..
as for the trick flow kit.. the stock injectors will be on small side.. 24lbs with a adjustable fuel pressure regulator would be the way to go.. but even still driveablity is an issue
i would say the best way to go..
price both of them out.. with all the supporting parts, and then figure out the negatives and positives of both..
Both need tunes to get driveability issues less.
Blower adds 50lbs. H/C/I loses 50lbs. 100lb difference between combos.
Very similar numbers. Low 300's are acheivable with the supporting products. They both would provide a good race.
People do not race to 2,500 rpm and let off.
Doing a h/c/i setup rebuilds the top-end of your engine.
The S trim will clutter up the engine bay.
Get a tune with either one and you'll have fun...

I knew that set of curves looked familiar 
Donavan ... Hows it goin
Why didn't you remind me we've worked together before
I finally remembered I already had his data
Soooo ... a quick cut & paste ... and ... Here it is
You can clearly see he has nothing to be unhappy about

Sorry Grady, I shoulda thrown that in there in the first place. I totally forgot that you already did all that work and made a graph for us, nice work remembering. I don't have anything to be unhappy about and neither does Grady, both cars push out great numbers. Whatever you choose will net you enough hp to put permagrin on your face for a while. With that said, everyone has pretty much covered the comparison between an H/C/I and a S/C, from here ya gotta take the knowledge and compare it with what you want and let us know what ya decide!

just a little tid bit i drove my car for a year with the sc and no tune and it ran fine, it was rich up top and ran 12.4's that way . the tune gained me 30 hp and some drivabilty but only because my car had both hci and blower.
