Sprintex or Vortech, which setup has more potential?

[bfrank1972]

I personally would like to see a TVS roots supercharger adapted for our motors.

Thanks swift! That's what I was looking for

Seems like the Vortech only makes the difference between 7-7500RPMS, which I could give a crap less about since I don't use those RPM's frequently enough.Then again, it's not a totally apples-to-apples comparison as you were using E50 and a better header with the Innovate unit.

I've driven a few examples of both. The vortech has a little more surge up top, especially if tuned to rev to 8k rpms. They aren't far off but I feel like the innovate has more mid-range thrust/torque. So on the track I like that as in higher gears I can push the car forward with the throttle. They aren't drastically different in power/performance. I'd love to drive a 350whp vortech on E85 though, that would be a different ball game.

I should have a 350whp vortech on e85 setup soon that you can drive.. the car is awaiting the parts to be shipped. Now I really need new brakes!

If it wasn't ethanol vs 93 you'd have my attention

that was also a very early revision of his innovate tune. i'd venture to say he's making comparable power to that dyno on 93 now or will be in the near future.

the innovate is not a good pick for 250-280whp. at least not as it is sold today and not on regular pump 91 or 93.

I'm not looking at it as though I won't upgrade from the standard package, though. It's a question of how much headroom I have to improve. The Sprintex S/C is supposedly capable of handling up to 2bar of boost and is best paired with 1-2L engines. Exhaust/fuel/cooling/tuning upgrades should squeeze more potential out of it, but how much is what I wonder.

I'm kinda leaning more towards the Vortech because it seems a more common choice, it's readily available with an air-to-air intercooler, the unit can be upgraded to a larger one if need be, and the support network seems greater. It's just that everything I've read elsewhere tells me that a twin screw is the superior unit from a basic engineering standpoint.

Oh and I know it's an incredibly stupid reason, but I like the packaging of the Vortech better; having the blower atop the intake plenum looks out of place if you ask me.

I think the Innovate kit is becoming more and more popular, just due to the simplicity and low cost of it. I don't think the IC is going to give tremendous results, just add a margin of safety on crappier gas. As for the coolant capacity, it's not hard to add a larger external reservoir if need be, but it adds more weight overall, and with the IC sitting above the engine like most Subarus, it will heat soak eventually.

There is a Jackson Racing S/C kit coming out shortly as well also using a centrifugal S/C, should be very similar to the Vortech in terms of performance.

I've compared Innovate and Vortech plots on 93 and E85 and generally the Innovate makes more torque throughout most of the powerband, but it runs out of steam around 6500 RPM where the Vortech will keep up all the way to redline. That's why it makes more HP than the Innovate, but it's at the very top end.

For a daily driver I'd take the Innovate all day long. 300whp though is going to be a struggle with it, like completely maxed out. I think both will require E85 to hit 300whp but the Vortech is going to get there much easier.

Turbo is always going to give the best results as far as torque and HP, the units people are putting on these cars are good for 20psi and they are being run at 8-10psi. Turbos like the GT28 and PT55 P&L is using aren't really laggy either on this car.

Here is a guide for you:

Stock Car with Vortech
301HP+ (Sustained Usage, requires clutch, Fuel Injectors, pump, pulley)
300HP E85 (Smaller Pulley, Fuel Injectors Pump)(Clutch wear will be heavy)
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)

Moto-East hit 220whp (dynojet) on 93 octane with the stock Innovate pulley and 250whp on E85.

They are at the end of this video:

Not knocking it but Moto-East is in bed with Innovate.
Secondly Moto-East posts about as much detail about his testing and tuning as Innovate does. They are both good at talking about dyno numbers that's about it.

I would love to see the same results replicated more than 2-3 pulls with the hood closed back to back after the kit heat soaks.

"Not knocking moto-east, just totally questioning his credibility."

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

I'd like to see the Sprintex/Innovate unit with intercooler, smaller pulley, 93 octane, full exhaust and upgraded pump/injectors. That would help me make up my mind.

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