I have not but jokerz has ported his own, seems pretty easy

I've ported my 1.3L eaton and it isn't that difficult, just majorly time consuming. I have a 27gallon compressor and it can't keep up so you spend some of the time waiting for the compressor to build air pressure (you can keep porting with lower pressure, but it doesn't eat the material as fast). You're also going to need eaton's blue needle bearing grease, some loctite gasket maker and some eaton/gm gear oil for reassembly. Also, check torque specs on the s/c case bolts before disassembly so you have an idea during reassembly.

 

Those bolts are supposed to be one time use, TTY.

Just saying.

 

Not realy worth it for the time involved and to do it right the snout needs to be welded in spots if you send Jokerz a assembled blower he will return a assembled blower. His results are consistent and if you keep the blower under 25k rpm he warrenties his work. He has many 9 sec cars with his builds and a car knocking on 8s.

Anybody can port superchargers or cylinder heads, and polish it up to look pretty.

You're paying for people with the knowledge to do it right. Hogging out some aluminum is not the same thing as skillfully managing airflow. Obviously a supercharger is not as complex as a cylinder head in terms of curve and flow, but the idea is there.

 

If you want consistent quality, expectations, and performance, I really doubt you will surpass that with hand ported blowers.

We have one design, two throttle body openings, the only one offering an o-ring on the large snout openings so you don't have to use any sealant there, and we are the only one that spins the blowers on a test stand, under load, prior to shipping out.

I'm not saying our competitors can't match our performance, but I am confident we make as much power as anyone and are more consistent than anyone.

Yeah, we cost a bit more, but our lead times are usually two weeks or less, and the results are there.

Well jokerz is fastest one around so you can't argue that. He must be doing something right.

 

I can argue it, I choose not to.

Do you think, honestly, a 5 hp difference from one blower port to another is going to make much difference.

In fact, I know the two blowers were on a dyno test recently and zero difference.

I don't market as well as he does, I will admit that, but I won't admit his design makes more power, period.

Those are just some of the times my customers have been putting down

My design is consistent regardless of what is being said. No one knows my process of porting. No one knows what I do how i cut or where I go. Anyone who does porting in real life and is hands on knows that air creates a air boundary layer that's fills in imperfections . The other thing is my design takes into consideration how the air travels inside the case and how the shapes you port effect the air. My other feature that helps me gain the edge is low pressure high pressure points inside the case. Meaning if you port a low pressure area you just lost horsepower. Guess what I know those points. I know as a positive others did not do the amount of testing I did. 15 designs and 15 different areas of testing on blowers I can tell you I can swing he dyno from 24 hp gained to 42 hp gained with some minor changes in porting. I can make torque at the flick of a switch.

Recently did a test With one of my old ports vs my new port design and it picked up 1.5 lbs over the old on the same day

Here is the test from last week same day

I would argue any decent ported blower would give similar results Brett. It's a ballpark 30rwhp mod on a 9 second build that is a drop in the bucket.

Not like porting is adding 100+hp. Good marketing but a bit misleading.

Off topic: That 9.001 would of hurt. Soo bloody close.

 

I wonder if anybody has the option for people who want a ported blower on their 24/7 daily car and can't have any downtime? Like, the porting company would send the customer a ported supercharger in its entirety and the customer would send the porting company their old supercharger once the new ported one is installed.

I was personally told of a back to back test where the results were the same power. I don't document like Brett does, as I have a day job, kids, family, and if course, spend countless hours on this forum, lol.

The place that I work with to do the CNC porting is very well known. I brought them a blower in February 2013, as there was a void in the community.

The void was that while the performance of a ported blower was pretty consistent, relatively, the visual quality was severely lacking.

Unsolicited, friends, and strangers, would pm me, text, and email pictures of the inside of their blowers.
They were disappointed that they didn't look like the pictures.
Jagged edges, very rough and messed up looking.

As for the times posted avove, again, I don't have and collect the data, shame on me, but I do know that a few tuners with the fastest V's in the country sends a big box with 3-4 blowers at a time for CNC porting. I don't ask which car it's for, what times does it run.
Let's be honest, there are guys out there that race for money, and a lot of it, and don't want others knowing what's in their sauce.

I had an exchange program, but a few times the blowers, whether being sent out or coming back, were GM rejects and the solid coupler didn't fix the noise.

As such, at the time, we discontinued it.

Now that I have access to a test stand that can put the blower on a 10 psi load, I can reconsider it, but currently have few good cores, and I'm not ready, yet, to swap them.

But, now that I can package new rotor packs, though they are expensive, it's something to consider.

Anyway, my apologies to the OP, this wasn't what he asked about, but I felt the need to respond to another person's comments.

Some do port their own. Some are quite successful.

We're fortunate to have a couple-Jokerz, Karch-reputable guys that from what I've seen do high quality work.
My only personal experience was with Brett aka Jokerz, well and Jesse Bubb-we don't want to talk about that..
Not only was Brett's work top notch he bent over backward for me.
I was also impressed with his integrity and honesty. I needed a really quick turn around. Brett told me he wished he had more time as he knew he could do more.
I could tell it pained him to hand it over in what he considered less than perfect.

It looked pretty dam good to me with gains in-line with has been stated.
Work was performed 07-23-2015

 

I am just here to say that I 100% agree that Jokerz ports are nice and if I didn't already have a ported blower I would buy one of those but I will also say those blowers damn sure ain't the reason the cars are running what they are running. Even if they made 20-30hp over the next guys port that is nothing in the grand scheme of things lol.

 

I would add, however, that all the little improvements add up. Port the blower, snout, add quality heads, headers, a good intake and 102mm TB, good exhaust system. All together you do make a big difference. If you've got a great blower and snout port but stock heads and LS9 cam, stock TB...the higher power levels get difficult.

I know some guys have done amazingly well with a setup with the LS9 cam, stock heads (ported?), and something like E85. But without a full-on assault on airflow upgrades the upper stratosphere is much harder to reach.

To repeat what many, many have said before me: You can't compare a single part swap fairly. What you are measuring is a system. The part you just swapped is part of that system. What netted one setup 30whp might add 50hp to another with a different combination of parts....

 

We offer it in house as well.
