Innovate (Sprintex) Supercharger Owners Topic

I get a picture to paste.

My point whether I'm a myth buster or not is we are seeing the Sprintex IC kit out performing the Vortech.

Case closed until I say told you so, very soon

The issue is there are lots of tuners on here like Bill@Delicious, Mike@Moto-East, Shiv@Vishnu/OFT, and users like Mike@CSG who have experience with every type of SC kit for this car. They are all going to say and and show you the same thing which isn't what you are saying.

It does come down to the efficiency of the blower and how they operate. Like just said, the PD supercharger isn't very efficient when spinning at high RPMs but the fact the boost isn't directly tied to RPM gives great low and mid-range.

Now the 335 is large enough it just overcomes all of that and the 210+ is supposed to just be more efficient in its design so you don't take the hit up top like with the current kit.

I'd be interested in seeing a dyno plot with the 335 on the FA20.

It's very interesting, and very bizarre data. If you convert the numbers on the Ryan's plot then it says that the Innovate made peak 207hp/176tq and the Vortech made peak 193hp/156tq. Those numbers are crazy-low! They're just numbers though.

But look at Kspider's plot running a smaller pulley and e85. Kspider's plot probably does show more power than a centrifugal plot on 91/92 octane.

However, it seems incredibly crazy that the same kit with a bigger pulley and crappier gas would make the exact same power. The sample size on IC Intercooler plot is extremely small, so anything is possible I suppose, but this just doesn't add up.

Not what he thinks of the kit overall but of air flow, efficiency and top end power which is what is being argued by Ryan. Bill has the innovate kit for other reasons one of which is to further refine the tune that he was contracted to do for innovate.

Mine has been clicking for a year.... On off throttle clicking I was told was due to the race pads I have. Maybe not?

Does anyone else have this clicking coming from the rear axle?

I was making the right turn at light and got on it hard in second gear

Should have spun the tires harder.

Maybe I have the click too..

It tells me that by tuning the higher drag system for smoothness and driveability he's able to translate those improvements to the other kits, thus quartering his work. I see zero fault in this, in fact if it's true I'd applaud him.

With a PD blower like a twin screw, the displacement is tied to RPM. With a centrifugal, the pressure ratio is tied to rpm.

Note that as IAT (post blower) goes up, mass flow can decline even though displacement is (nearly) constant. I'm really curious about downstream IAT on the twin screws. I suspect that increasing charge temp (and therefore lower charge density) is at least part of what is killing the top end.

Good grief, both good options:

pretty sure its vortech vs innovate. Vortech with the higher top end and innovate higher up to 6.5k rmp

Most likely, but just like to be sure.

He said the twin screw has lots of drag on the motor and probably takes 30-40 whp just to spin it. Hopefully he can chime in.

It is a real toss up and highly dependent on what you are looking for as the end customers. Here is the difference from my perspective and why I chose an Innovate on my personal development car. Though our second development car has a Kraftwerks kit, which is a LOT different.

The twin screws offer tons of immediate torque as low as 1500 RPM's and torque across the board. It is a wonderful feeling to be able to cruise in 6th gear at 1500 or so and floor it and be pushed back in your seat.

The centrifugals are similar down low, but not enough in my mind. I wanted something with a flat torque curve and they just do not offer this. But the benefit is efficiency and top end power, especially on the Kraftwerks kit. There is definite top end improvement, but you sacrifice a little low end torque.

Being I am not one for the top end and wanted a wider power band I opted for the Innovate. Though the Kraftwerks kits on our second development car hauls butt on the top end, which makes me a little jealous also, but I do not want a "good drivers award".

Cheers,

I have been following the SC options, and I have decided on an Innovate kit. I haven't decided if i want the tuner or the Carb kit. Is that graph with CARB tunes? Or custom tunes?
