Had Brett port and powder coat my Audi supercharger. It looks and performs great. Definitely recommend Jokerz to anyone looking for a porter. Performance definitely exceeded my expectations.

Brett went way beyond my expectations rebuilding, porting then painting my TVS 2.3 supercharger. Wouldn't hesitate to use him again. Absolutely fantastic work! Thank you!

I have had the pleasure now of doing business with Brett and his Jokerz Performance twice.The first time was when I had to go into my engine to repair a bad cam install and I figured while I was there why not change the heads on my CTS-V from the stock LSA heads to some aftermarket heads. The pairing of his his blower and those heads and someone else's cam got me to 760 horsepower at the wheel. Everything I wanted it to be.Fast forward a couple of years and the LSA block, is starting to give me signs that it's in its waning days. So I decided to replace the 376 with a 393 block and move his blower, which was working perfectly onto the 393 and use the existing heads I had. But then I got the looking around on his site and wanted to change up this color scheme of my motor so I got his red powder coated blower and matching valve covers and hoses and now it will look just as good as it goes fast.

Zero customer service. I sent in my supercharger to be rebuilt, and there was zero communication. Any calls were answered by a recording that they are busy working and to send an email. Any emails that were actually responded to were answered with broken sentences or single word responses by Brett. Most emails weren't answered at all.I received my supercharger back in what appeared to be a box of trash. There was not paperwork and I never received any documentation as to what was done to it.I would not recommend this company.

I sent In my SVT Lightning Eaton blower to be ported. Brett and I had several phone/email conversations, and even with the holidays, he returned it to me promptly. I appreciated the discussions, and the work was completed beautifully.

Highly recommend Jokerz Performance. Brett is very professional. He is a great guy and pays attention to every little detail. I have an older discontinued supercharger and Brett made sure to take extra care of it and was able to hunt down the parts it needed. He kept me up to date during the whole process. He really cares about his customers and their goals. Jokerz is the best in the business period!! Wouldn t use anyone else. Highly recommend Jokerz Performance for all your supercharger porting and needs!Service: Supercharger/blower/turbo installations

Sent my lightning supercharger out to be ported and powder coated. They had it for about a month and half, which is a long time. Gave them a call. Everytime I called I felt better about them working on it. I tried to paint it myself but ended up looking horrible so I had jokerz powder coat it. He wanted to make sure it was a good product, they bead blasted, washed and installed new bearings. They also had to wait on the color which came out great! The port was nice and even. They even touched up the bolts and the snout pulley with some paint and made it look great. They package in between two blocks of foam. Nice to know it s packaged so nothing will happen to it.

Working with Jokerz performance has been a great experience, Brett is so very knowledgeable on IHI superchargers and products. Done an outstanding job on porting/polishing my snout on Challenger Hellcat. He made himself available for questions and went above the call of duty to help answer them even though I know he was busy but he cares enough to take the time to return calls. There is no one else I would let do my work.Keep up the great work and customer service Jokerz.I recommend them to all my mopar peeps and also anyone that needs high performance work done on any make/model superchargers!Thanks Brett!

Company is named properly. The whole company is a joke. Took almost 4 months to port a brand new blower, communication was terrible, pathetic excuses when asked about delays, and forgot to ship parts back that were part of the supercharger. Was recommended this place by many people and my experience was absolutely terrible to put it nicely. Not to mention they charged the shop that is building my car twice claiming they never received the first payment for the porting service when after the payment was made, shipping instructions were provided. Moral of the story, if you are not a big time performance shop on the internet, you will be treated like dirt. I will never recommend this company to anyone. Let s just hope whatever porting they did actually works.Service: Supercharger/blower/turbo installations

These dudes are the Absolute best , Brett has always treated me more like a friend then a customer which I appreciate.He's a straight up kinda dude and most importantly he doesn't talk to people like he is a god and no one knows anything that he knows, Theres a certain other shop will treat you like he's surprised you can tie your own shoe laces.The quality of Jokerz work is always excellent and also always reliable. I would recommend them before anyone else in the supercharger rebuilding industry especially if you don't want to deal with bs.

Customer Service is unmatched!... Before even sending my blower in for porting I reached out to get some questions answered and Brett spent a decent amount of time on the phone with me talking though the process and advising me on what to do based on my set up and goals. I was impressed with his knowledge and could tell his passion just from speaking over the phone and I didn't even spend a dollar with his company yet!I sent my blower in to get ported and had tremendous HP gains! Was elated at the results!... 6 months in I had an issue with my blower. I reached out to Brett and he said to send it in so they could diagnose the issue. Thought it would take a while being that they're very busy, but they literally had it fixed and sent back out within a couple business days.Brett called me and explained what happened and went ABOVE AND BEYOND to help out and get it back to me. Finding people who stand by their work and product is rare these days and Brett is an amazing business owner and absolutely awesome how he helped out anyway he could. I wish I could do more business with Jokerz, thanks again Brett!- INV800

Brett and Jokerz are the only place that I will let touch my supercharger. Brett is an excellent business man and his work is top notch.Don t let any negative reviews turn you away Jokerz is legit. Some people you cannot make happy no matter what but for me I am ecstatic with their workmanship, customer service and the speed of service.

Brett is extremely knowledgeable when it comes to porting blowers or manifolds. With his expert skills he is able to get the most power out of a blower or manifold with his porting skills. Brett is easy to deal with and is straight forward. I send all my customersParts to him. I wouldn t trust anyone else.Service: Supercharger/blower/turbo installations

Purchased a SuperCharger from Lance Draeger and had it rebuilt, powder coated, and the snout ported with a grip tech pulley installed. The quality of work was excellent and delivered on time, during packaging the by-pass valve was accidentally left out. So I contacted Bret about the issue to which he asked for a photo of the missing part and promptly replaced it. I have contacted him a few times with customer support questions and he has always been extremely helpful and courteous. Certainly will be a customer for many years to come. Thanks guys!Service: Supercharger/blower/turbo installations

I gained almost 100 whp and 100 torque with his Full Tilt port on my LSA 1.9 blower. No other changes at all! Brett is honest and straight forward with his business. He will give you the truth, whether you like it or not. He won t tell you something will work unless he knows it will work. You can trust him to make more power with any supercharger out there.Service: Supercharger/blower/turbo installations

I had heard awesome things about jokerz performance and the owner brett prior to me using them. When it came time to send my supercharger off. To be ported I knew I had to use them. As soon as they got the supercharger Brett called me and let me know it would need rebuilt, which I expect, i always mentioned to him I was concerned about my. Short window coming up for my tune. Brett let me know this shouldn't be a problem and they would get out to me before the tune date. They not only accomplished this but went above and beyond on taking care of me. I definitely am referring people jokerz performance.

Horrible customer service. No follow up when I asked did they get payment. I even sent a screen shot. Didn't take me serious at all. Charged me $93 PayPal fee without telling me I will be charged and I asked to at least split the differece. If I sold a $3,100 blower to a customer, I'm sending it signature only and following up with them.
