For those who have doubt in the Vortech kit please read.

Wow.

They a corrected but you will see more power because you'll have more boost at sea leave. I see it being 390- 400 at sea level.

Congratulations on that beast!

No I have the upgrade fuel pump John offers I don't remember what it is off the top of my head.

Congratulations on your new powah!!! Very glad to hear that you are happy with your Vortech system, and thank you for the support.

I hadn't thought of that. I am used to turbos where the boost is adjustable.

Get some numbers on 93!

I'm sure I am not the only one with this stance on the matter, but my issue with the supercharger option is the lack of torque, and the stupid amount of boost you have to run on them to make them comparable to most of the turbo applications out there already.

12psi on the stock motor isn't the greatest idea, and overall HP isn't what I'm looking for - it is the TORQUE that I want. Turbo kits like AVO's 5psi offering on standard 91 octane (most of us have 92 around) and zero fuel system mods puts out 230whp/197tq - which is more torque and close to your HP figure after you converted to e85, new injectors, new fuel pump, and a smaller pulley. FA20Club's kit nets even more on 5psi. 286whp/210tq.


The bottom line is there are more cost effective, scalable, and more efficient options out there. Supercharger on this motor doesn't appear to be worth the money.

Just to confirm - the only difference in mods between the last two plots are the upgraded compressor and a smaller pulley? That's a lot more power than I expected to be gained from just that. I guess the corn juice is really making this thing open up.

And shit, I just noticed this is on a heartbreaker?

Agreed - but can we not turn every Supercharger dyno thread into a Turbo vs. Supercharger discussion? There are plenty of people who have valid reasons for considering a Supercharger over a Turbo, and nowhere in this thread was the OP trying to say one was better than the other.

So then dont buy a supercharger? Spend your money the way you want. OP obviously liked this route.

Nice results!

[NorseLegend]

I'd love to see those, or even just 300whp on 91 w/ 12 psi and the smaller pulley. That would be epic.


All your base are belong to me.

I wouldn't necessarily call an old software Dyno Dynamics a heartbreaker dyno. I would also liked to have seen these runs done in Shootout mode.

With a thread title specifically targeted to those to doubt the Vortech kit, I am simply stating my reason to doubt, not saying one is better than the other, but rather (as I stated in my first sentence) this is MY issue with it. Good day to you, sir.

Understood - but doubt doesn't only come in a Turbo vs. Supercharger format. Either way, I hear what you're saying.
