Sprintex or Vortech, which setup has more potential?

i believe @moto-mike may have recently done a setup just like that, no? if not, @FA20Club.com might have. I'm not sure @DeliciousTuning has done any smaller pulley setups yet (unless @robispec is running one)

fixed your post. if you're going to insult the man, don't try to church it up.

Not knocking his credibility or abilities, just how these guys avoid all the straight and hard questions about the kit and the issues.

They skip those and focus on the marketing and cherry picked dynos.

You are still drawing power from the motor to create 12 psi but only using 9psi of it and bleeding the rest off.

This runs the charger and gearbox harder but doesn't really use it. You can probably see where i am going with this.

Waste gated centri SCs generate more HP then same psi level non wastegated centris, also IATs drop when the wastegate actuates, I didn't believe it either til I did some research on mustangs and corvettes... The info is out there, just have to look instead of posting.

Nothing i said is incorrect. Running the smaller pulley increases drag on the engine(more parasitic drag). The charger is ran harder(more rpm), the gearbox is ran harder(more rpm).

I didnt say it would heat up the charge or make less power.

Anyways we havent seen anyone even attempt this yet.

Wasn't the car-b-que car running this setup, pre cookout?

Side note: I really wish the nearest E85 retailer wasn't 30 miles away

Expect about 250-270whp with that set up.

270HP 93 Octane (Change Fuel Pump/Injectors)
250HP 93 Octane (No fuel system or other changes)
220HP 91/92 Octane (No Fuel System or Other Changes)

Stock Car with Innovate Non-Intercooled
300HP+ (Not Possible without intercooler if at all)
280HP E85 Octane (In Future)(Pulley Change Fuel Pump/Injectors/Meth Injection)(Clutch Wear Heavy)
250HP E85 Octane (Fuel Pump, Injectors)(Consider Meth Injection)
220HP E85 (No Fuel System or Other Changes)
205HP 93 Octane (No other changes)
190HP 91 Octane (No changes)

I'm at 274hp tuned on 92 WAWA gas, much to moto-mikes misery. Still alot left on the table, very safe tune with only 20degrees timing.

Negative he was running flex-fuel setup with 12.5 psi pulley.

That's the thing, it doesn't since the back force exerted on the blower does not go up, heat is the by product of wasted energy, if your IAT's go down, your not wasting as much energy.

If parasitic lag increases, you would generate less power at the same psi. I just realized your trying to make 2 opposite statements in that post. Google, wastegated centri vs non wastegated centri.

I'm almost postitive that it was wastegated as well, not sure that was ever publicized though.

here's the video of their dyno when it was on pumpgas:

I do know there is a wastegated vortech being installed w/ the 12 PSI pulley and hitting the dyno any minute now, pretty sure it's going to be run on 93 exclusively.

Gems? Thought he was on e85 and a different blower.

Nope. Another poster here (on the right coast). I'm sure he'll chime in with dyno's shortly.

Oh the great fire chucker... 290 is nice, not worth burning in a v-irey inferno though.

It will be nice to see, I'm doing some driver light weighting before I do the wastegate, so another couple of months before I do mine.
