Supercharger Porting Q&A and Resource Thread

[EvolutionArmory]

I hit 1389 on the stock blower with a 3.2 ratio and don’t see power cuts on the Ultracharger file

I’ve never logged MAF when DA is -2000 or lower but I bet I’d hit 1389 for much longer if I did.

Fred, it’s funny that you think 2 c or d level “tuners” know more about the Magnuson blower than the company that wrote the original software for it. 🤣🤣

You don’t know that IAT’s weren’t the issue with the Magnuson. Summer hasn’t even started yet…..

I also have the Ultracharger file, and at 1389 the BPV opens to limit and hold a max of 1389, just like all the other files on the market.

Post your datalog..

None of us are running the Magnuson file so none of our data logs are relevant to the discussion we’re having about the Magnuson.

I hit 1389 on the Ultracharger file, but not for any sustained amount of time.

So, you hit it for a fraction of a second and then couldn’t sustain the value of 1389, doesn’t really prove your point.

Nonetheless, show a snap of your BPV position or just share the datalog link, odds are even at such little amount you spent at 1389, the BPV still moved slightly.

And like I said before, neither is running the APR Magnuson tune so you have no idea what they did or didn’t do to the tune.

You/we can speculate all we want but don’t know what they did.

What we do know is at that point, they were able to go faster than anyone else had before in shitty DA and 105 degrees ambient temps.

Any update on this? I would think that a non-race port would really just be opening up the inlet and outlet like you're doing here.

[Fresh.S4]

Their really doesn't need to be a term called a "race port".
You either are gonna do the full job grinding all the required spots or your not. Why would any porter offer different levels?
Even Brett quit doing that option years ago.

Jokerz stopped doing a port where he ground off so much material that epoxy was needed. He found that machining less material actually flowed close to the same amount of air and made about the same power. Close enough that it wasn’t even worth mentioning the difference in airflow.

A more “aggressive” port doesn’t always translate to more power. The idea is to remove only as much material as necessary to get the job done.

I will never buy a hand done port from anyone. It’s impossible to get repeatable results by hand.

Race ports are still a thing. Brett only does like one a year for our platform when he comes across a particular variant of our blower that has more material supporting the bearing wall. What Brett has explained is that the amount of material you remove from the bearing support affects the timing of the rotors. That rotors act like valves sealing back against that wall. The ports that have very little material left in that area are considered race ports. The peak power gets made at a higher rotor RPM on a race port, so your you need more pulley ratio to take advantage of it, and as we all know, cooling becomes even more of an issue. Windows need to be cut in to the BPV area in order to remove that much material so you're creating another point of failure, so he switched to a good all around port that is optimized to a 3.25 ratio that you don't have to wring it out to take advantage of.

Fred, what criteria does he use to determine what is suitable for a “race port”?

Is it a specific compressor housing part number? A certain production year range? Just chance variations in the castings?

Did he tell you?

When I talked to him he didn’t mention anything about that but you’ve probably talked to him more than once unlike me.

When I talked to him he just said he does the less aggressive port now because opening it up more didn’t offer any more flow.

It's an early variant of our SCs. If you look at the BPV area, it's solid , no ribs. I don't know the year/vehicle that they are found in. Screenshot_20230725_094437_Facebook.jpg

Good info. Thanks.

It would be cool to know what the part number variant was.

Ya'll are gonna flip here, but the last bit of power is by modifying the rotor blades at the inlet. By doing should have a similar effect to opening the case as Roofrails describes allowing much more inlet flow and changing rotor timing by a lot........Somebody do it!

Looking to port my supercharger but I can only find Jokerz offering the service. I messaged Shane Horning and Performancebuilds months ago and received no response. With Jokerz it would be over $2000 given that I’m in Canada, shipping would be another issue. With the winters here (-30c) IATs are no problem

Contact VastAZ. He's your guy.

B5 S4 - Laser Red // Stage III
C7 A6 - Magnuson TVS1740 // 10.69@128

[EvolutionArmory]

Vast AZ is the only real solution right now. Brett from Jokerz told me he’s getting out of B8’s because he doesn’t make any money on them, all the guys that were porting blowers a few years ago like Shane Horning and Matty are hard to get ahold of, JHM offers porting but I’ve never seen anyone posts results from one so that leaves Marshall from Vast AZ.

So far my Vast AZ ported blower is working out great. I’m able to run decent times very consistently now and am way less dependent on decent weather to run good times. It just performs all day every day now.

In 80 degree weather with the port I’m able to run the times I needed 40-50 degree weather to run with the stock blower and that should just improve when boost season finally gets here. Marshall from Vast AZ is the only porter that is actually putting out work and showing results in 2024.

If you are looking for a completely solid hand ported blower, ive got one ready to ship now, no waiting weeks.
I learned from Brett, Matty, and Brad years ago right before they left the scene pre covid. With their information I am able to replicate all of the universal cuts and smoothing to insure maximum flow. No different 'stages', just one solid job all the way through so there is no confusion. I do these as requested, mostly local but there are a few of my ports floating around from folks that ive shipped to and haven't had a complaint yet from the folks who have my units.
I purposely price my jobs low because 1) i am a long-time community member and 2) everyone should be rocking a ported blower.
$1250 shipped (conus) gets you a completely ported blower all the way through, new bearings and fresh oil.

send me a pm and ill square you away with a fast turn around time.

I've been doing a lot of research and speaking to a lot of people I know about power increasing for my car. I have been playing around with the idea of a ported or aftermarket blower. No matter what combo of fuel, blower, and cooling I start to research, in our cars the factory setup/system with the IC bricks sucks when you start climbing over 400hp (which is stage 2 and up).

If I do take the plunge the only way I am doing it on my car is going to be using a cooling system that uses the AC refrigerant to cool the IC bricks. The likely setup will be eliminating the IC core in the front bumper and just running the chiller (the IC core would actually put heat into the system and is counter productive). I also plan on doing meth/water injection in addition to the Refrigeration cooler along with pump or race gas along with a rebuilt/stronger HPFP and a more stout in tank setup. (I don't plan on using any corn fuel).

Using the above mentioned setup, I should be able to avoid any fuel starvation or detonation and keep the motor together and strong.

Sounds to me like you’re going to want to get the forced induction inter chiller universal kit. It’s not to be confused with the earlier inefficient killer chillers. Only about 1600 USD . I have one just not installed

A real world 60-130 ported blower comparison done in about as even conditions as I could. The difference equals about 40-45 wheel horsepower in my case.

Jackal 93 and meth tune. Vast AZ race port.

The Vast AZ ported blower keeps dipping deeper into the 7’s.

This is on Jackal’s E40 meth tune with VP Speed Sauce Plus.

This is a 3.2 pulley ratio. With a higher ratio I am pretty confident it would be a consistent low 7’s car. It just runs 7’s every time I try now.

He acted very professional all throughout and provided helpful information while going above and beyond. His work looks very consistent with competitors with a significantly lower price. Attention to detail is incredible.

If you’re looking for a ported blower I highly recommend him.

Hello everyone. Late to the party but interested in porting my blower for my c7 a6. I already have all supporting mods and currently stage 2+ Jackal tuned. Is Shane still in the game? Seeing options for ports, I also considered VastAz but want to see what others think

Is this their race port? What other mods do you have?

[Nillious]

Anybody ever ported a charger on stage 1? Would the tune just bleed any extra boost you got. I have a spare charger laying around and have the equipment for porting.

People have. If there's room on your stage 1 tune to increase boost to match the map_sp, then definitely.

C7 A6 - Magnuson TVS1740 // 10.52@131

Yup!
That's how I started. Apr stage1/ ported blower.
Does it bleed boost? Probably
Was it overkill for mods? Probably
Was it worth it? Yup.
Highly recommend that you go for it, getting a ported blower early on will just augment the power increase of other mods as you add them. BUT! I think only if you know you will make your way to going stage2,tp, pullies and matching tb (in order to really maximize). Or for folks who are going all in on the under stuff maintenance and the blower needs to come off anyways.

[Fresh.S4]

next ported blower will be ready this weekend.
$1275 shipped, conus.

optional 80mm tb kit.

[EvolutionArmory]

Any performance data on any of your ports yet Ted?

How do they stack up compared to Vast?
