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 New https://cimg4.ibsrv.net/gimg/www.mbw...e5a16351f5.jpg OLDhttps://cimg1.ibsrv.net/gimg/www.mbw...bcfa06af9f.jpg OLD https://cimg7.ibsrv.net/gimg/www.mbw...ef7489fd87.jpg NEW https://cimg9.ibsrv.net/gimg/www.mbw...e6f747b3f0.jpg OLD https://cimg0.ibsrv.net/gimg/www.mbw...cc59f27044.jpg NEW https://cimg4.ibsrv.net/gimg/www.mbw...cdfd00547e.jpg New https://cimg6.ibsrv.net/gimg/www.mbw...75155138ff.jpg Old vs new https://cimg3.ibsrv.net/gimg/www.mbw...493853fc38.jpg Together Stage 2 and 3 and Gen3https://cimg5.ibsrv.net/gimg/www.mbw...ead7c09264.jpg |

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 |

Nice gains mate! I'm also surprised boost went up with same pulley. These track times will be killer!
|
Curious why you guys are surprised the boost increased? The impeller design is improved so isn't that a direct byproduct?
|
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. |

thought you said your car made 700whp?
|
Proof is in the MPH this test was done on 67mm pulley on pump fuel

His car traps around 140mph. |
He was also on the lowest boost pulley |

He was also on the lowest boost pulley 30wkw gain but its leaning out looks like i need to adjust tune and fuel pressure for 98ron https://cimg1.ibsrv.net/gimg/www.mbw...83502cc66e.jpg |
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 |

I didn't notice that. But now that you mention it, my car has that dip also, yet I hardly ever see it on an M156 dyno plot....

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.
