** Awful experience with Carson Performance** **Please read** I own the white Rx7 FB which can be seen in Monkey London’s recent youtube videos and on instagram. I want to let people know of my frustration and dissatisfying experience with Carson Performance. The problem was (still is) that my car can’t get up to the correct temperature. The water and oil temps were around 55c and 53. When I dropped the car off I informed Simon that the car was over boosting & asked him not to put his foot down. A week later my car was on YouTube being rev’d until it hit the limiter to make it flame to create YouTube footage. To treat a customers car in this way is both unprofessional & disrespectful. The footage I saw could easily damage my engine. A couple of weeks later I’m told by Simon to buy an original water pump housing so he could fit a Mazda thermostat to solve the issue. After purchasing this part & sending it to him I was then told his original idea wasn’t going work. Waste of my time & money. Two months after I dropped off my car Simon finds & fits a aftermarket thermostat that will join straight to the water hose. He finally called to advise me that my car was up to temperature. He just needed to test drive and then I could collect it. Great! I reminded Simon again about the over boosting problem for the test drive. On collection I paid for the work done & began my drive home however I soon noticed the temperatures hadn’t changed. Why would you tell a customer you’ve fixed the problem when it’s so obvious nothing has changed? As soon as I got home I called Simon but it went to voicemail so I left a message explaining nothing has been fixed and to call me as soon as he gets this message. Days went past and no callback from Simon. Now I’m pissed off. Then a week later to my horror I find my car on you tube again. With the title “Rx7 rips up the street!” I haven’t given permission for my car to be used in a video and for some random person that is not a mechanic & doesn’t even work for Carson’s to come along for a so called “test drive”. Through the entire joyride Simon did not once look at the the gauges. If he had he would of noticed that the water and oil temps were in the 50s still! Hence why the rev limiter was cutting in at 5000! Any person would think “that’s not right” and check the gauges but a mechanic should know that’s not right & check.. but not Simon. He then proceeds to accelerate over and over not even caring he’s continuously hitting the limiter. Again Simon did not once look at the gauges as he would of noticed the over boosting warning light flash at him every time he accelerated. There was no half throttle or fevering of the throttle at any time during the joyride as stated in the video. The car was over boosting by 6 psi and over 30c under what the water and oil temperatures should of been. The combination of the two wouldn’t do any engine any good but to a rotary engine this can have devastating consequences as confirmed by a rotary specialist who approached after seeing the video on YouTube. The only thing that saved the engine from detonating was the limiter that he chose to ignore. Two weeks later I still haven’t heard from Simon. So I phone again to let him know how displeased I was with his work and actions. And gave him a chance to explain himself. What I got from him makes It’s safe to say he is disrespectful and has little knowledge in his field. I’m sure he is capable of bolting on an exhaust and suspension parts but in my opinion that’s about it. If you’re thinking of using Carson Performance in the future I would think again. Thank you for reading.
