Old vs New ( WEISTEC INSIDE) results
Hi guys
Here is the difference between old stage 3 Weistec vs New Gen3 Weistec
Big differences in flow and design

So finally got the results for the GEN3
what surprises me is how efficient this blower is and how the boost has raised
we used the same 67mm pulley the same belt same fuel in the tank same spark plugs
Weather was exactly the same
we could only do 4 dyno passes as car snapped a strap on the dyno
ECU didn't have alot of time to learn but I'm sure with a few more passes it would of gained a little more power and that dip would of cleaned up
In a couple weeks we will be leaning on this tune a little more as car is a little boring
but I cant wait to get out there with the 60mm pulley and try and run some faster passes

I think the surprising part is that boost is raised throughout the rpm range. I would have expected the improved volumetric efficiency would only been noticeable up top. Basically the new design give better airflow everywhere.
Interesting though how rough and irregular they left the casting in the previous generation. Seems like there was a lot left on the table.

Proof is in the MPH this test was done on 67mm pulley on pump fuel

Generally speaking, boost drops when a charger is ported. It's to do with the airspeed (most likely) slowing down (by a small amount) vs the increase in overall flow capacity/ability. For boost to have gone up along with increased flow (let's assume there's more flow), the revised design must have been very well thought out indeed. Either that or the original was far from optimal.

He was also on the lowest boost pulley

Nice Brad. What’s the reason for the more pronounced dip at 5k rpm?

Its a mix of tune and fuel
Its pretty much dropping 2000 bar of pressure from 5k onwards
Needs a fuel system mate

That blower upgrade is definitely next gen! You picked up power everywhere and boost! Absolutely no negatives from the new blower.i was thinking it would of lost power under 5k rpms
You got me wanting to supercharge mine now lol

Yeah, I am 95% certain that it's a VVT thing which on my car wasn't 100% optimised because I was focused on peak power above 5000rpm. I actually think I managed to iron mine out and improve a little on the peak output, but haven't been able to dyno yet.
I'm not sure why Brad''s car has it though. He kindly sent me a log, but I'm not sure if the answer will be in there as it doesn't contain VVT numbers.
It could...just be a timing dip. My car seems hell bent on pulling 2 degrees from 5900 to 6300 rpm and then back up again after. It's not knock. I've managed to work around it, but it's not ideal.

....on that note....has anybody with a supercharger had a VVT tune done yet? It's not like they need more power, but damn I wonder what potential lies therein.
