You need to learn to feed your self knowledge.
I believe you will be driving this car as much as possible. The high HP MKIV guys only take their car out once in a while. How many have you seen delete it versus keeping it? Jesscia Barton does 9.2 in the quarter mile on a six speed, makes 1100+ HP on the same motor for a while now and still has the stock tensioner and her engine bay look nice, as well as other things on her too.
If you want to delete something, learn the purpose of it. The 7M is the grandfather of the Supra motors, I am excluding the early 6M and 5M, and everything was improved throughout the years. They had your bracket style tensioner and went to a spring loaded tensioner on the JZ series and even there newer cars have the spring loaded tensioner. There has not been one Toyota to use the bracket tensioning system that I have seen in a few years.
Take a look at when your car is running, that tensioner does not stay in one place, it will constantly move, your bracket will not allow that movement.
Let me spoon feed you once again and tell you that I have seen people delete the tensioner and ending up changing out seized water pumps and what not. You are creating the potential to put an extra strain on the bearings inside the water pump, power steering and alternator. I am not taking about one time, I have seen it a lot and not only on Supras but RX-7s as well.
When people advise you, don't response with "reason being?". That obviously shows that you believe we know nothing. Sure, there are some idiots on here who don't know anything but when advice comes in, read, listen, research and then respond with something intellectual.
If you want me to really explain what you are doing by running a shorter belt and bracket, I will draw a diagram showing the forces, there components and what it will do when your motor's pulleys are spinning at a rate of 7,000RPM but I highly doubt you will understand that.
If you want to go ahead and run the Venom parts and delete the tensioner, you are free to do so but you have been warned, so please don't create a thread saying you jar weird noises or your car is not charging properly and so fourth.
Don't think of it as us being douchebags in your thread but we are teaching you something and potentially helping you save money. Jetjock once told me, after searching for a solution to my 7M not idling and doing everything which no thread could solve, to block the turbulence from the fan clutch it see if it works. It did. Nobody had that problem in any thread and he helped me on that. He did not do it right away, but his theory was, instead if fishing for the man, teach a man to fish so he can feed himself. I told you to look at what you are doing by eliminating the tensioner and the reponse was "still doesn't answer my question.". See what I am talking about?
We are not in here to shit on your build thread because if you read all of that, you are probably thinking that. Instead of me saying, "Yeah, nice build," I saw something wrong and notified you. Message Tweet on here, he asked for my number for some advice on his build and for everything he said, I had a question and advised him what to do. He later posted in a thread where I asked another member why he would leave cables exposed and said "This guy always has question...jk jk."
I am not trying to put you through a quiz, which he probably does understand, but I am trying to show you problems that can happen. That enough of my rant.
