Hey guys i'm not sure if anyone of yall have done this but i was told by a local tuner that removing my clutch fan would make my engine rev quicker and also free up some stolen horses:icon_bigg. what am concerned about is with this mod i would have to use a pair of spal fans or upgraded radiator with a pair of spal fans for cooling would this really benifit my 7M as of now i have no cooling issues and where i live its hot all year round i don't wana do this if i'm going to run into problems. Please advise guys if you have any information on this subject
Clutch Fan Removal/Mod good or bad?

Where do you think the power for the electric fans comes from? One of the tuning magazines tested this myth years ago, forgot the car, but they only saw a couple HP on the dyno (within it's error range mind you) and lower HP when the e-fans turned on.
It's a crock.
It's a crock.
waste of time and money. as stated the extra power draw on the alternator cancels out the hp gained. you can go to a fixed fan setup and delete the clutch, but if the fan ever fails, it will do some damage

I agree with what ur saying i'll leave her as she is. What ways can i make her rev quicker without putting a lighter flywheel? i currently have a 3.9 Ratio diff is this my problem do i need to put a 4.1 which the manual supra comes with stock? The reason it has a 3.9 is because i did the Auto to Manual conversion using a R154 gearbox but retained my same automatic diff is this whats holding me back?
Autos have the same diff. In fact they went to 3.73's on the later models. Turbo car is never going to have the response of an NA, and reving is independant from acceleration. If you want to go faster, you need more power.
One piece driveshaft made a big difference for me, I snagged an aluminum one piece from shaftmasters I believe.

Would a better flowing turbo kit on my current setup answer my prays? cause i was planning on installing a precision 6262 turbo by June once God spares life. I feel that i'm pushing the limits of my upgraded CT26 currently i run 13-14psi when i push it to 15-17 i feel no difference if you wanna know my supporting mods just ask. But i would love quicker revving/more acceleration stronger mid and top end am i going the right way? is there anything else i can do?
I AM GOING TO ANSWER THIS QUESTION THEN A MOD SHOULD CLOSE THIS THREAD....
Me: Have you ever heard of an engine called the 2JZ?
Noob: Yes.
Me: That's good. Do you know how much power they are able to hold?
Noob: 800HP?
Me: Yes, that is pushing it but built is well over a 1000HP to the wheels.
Noob: Wow....Can the fan clutch hold that?
Me:Yes, want to know something else?
Noob: Sure.
Me: Many of them still run the stock clutch fan, so it won't make a difference on your street car so stop trying to convert to a less effective electrical fan setup.
At 15-17 PSI, you are going past the CT-26 efficiency range....

al lewis: That wasn't the point IBoughtASupra he was making.
Like stated, the power from the fans comes from the alternator, which gets it's power from...?

Don't forget about the asteroids Ian.
If you listen more than you talk, you will learn a lot about any engine. My point to show YOU, THE OP, was that those cars are making 1000HP to the wheels. A good portion of those cars are daily driven or driven very often. Many of them are running the stock fan clutch and it is not shredding into pieces at those power levels. That goes to show it is a reliable piece of Engineering that will work better than any aftermarket Electrical fan.
If a 1000HP car is using a fan clutch with no limitations, do you think your street car will have a problem?

I got that point a long time ago but the way u come off isn't pleasing and u need to chill i've been past that i wasn't even going to remove it i just ask a question since someone suggested it to hear yall's feedback now i'm on a different topic but i think i should open a new thread for this.
When talking about the forums, nobody is going to spoon feed you. Your question could be answered by a Google search, but like SupraCentral said, "The search police don't live here."
So I responded with a little story to see if you would understand my point but you were not able to comprehend what I was saying, you know, the moral of the story. Instead, you took that time to respond to me thinking I was trying to insult your 7M, which was the last thing I would do. I have helped and put together one of my own 7Ms just this other day.
I was not trying to insult you buy I am not going to spoon feed you as well. If I make a thread about something, trust me, I have searched well enough and PM'ed the most knowledgeable people. Ask Ian, IJ, how many engine questions I asked him before putting together an engine plus I has experience helping others put together their engine.
Here is a little story. My 7M, first one we put together, would not idle. I adjusted the TPS with no codes, checked the ISCV and it was in spec and then I changed my AFM with a known working one. I searched and all threads said the TPS needs adjusting, AFM is bad or ISCV is bad. I knew all those parts were good, so I made a thread.
Jetjock decided to chime in with a sarcastic comment. I did not post any angry smilies or say anything offensive. I said to myself, "look at this DoucheBag.". So he goes through the thread and suggest me check voltage, since an O-Scope is need to properly check the AFM. I did that, even though I knew it was not the problem. I posted back with my finding and waited on a reply.
Jetjock once again makes a post to another use, saying "teaching a man to fish for himself," so I again said to myself, "look at this fucking DoucheBag."
I posted a picture of my setup, a T4 setup. My AFM housing could not fit in the stock location and was angled slightly because of the intercooler piping.
Jetjock saw the picture and said turbulence from the clutch can cause my engine from not idiling, so I asked what should I do, he said put a filer on it since I did not have one. It did not help. So I looked at the setup myself, even if I put a filter on the AFM housing, air would still be pushed into through the filter by the clutch fan.
I went and got a piece of cardboard and put it in the middle between the clutch fan and AFM housing, not a good separation but it was good enough to block most of the air. I went and started the car and it idled with a slight misfire. I was happy because in six months I could not figure that out and with a lot of help and trial and error, it took another month, but was ready for the Summer.
The next week after I started it, the car sold right away, I didn't even register it, just sold because of my time and effort to make it right.
If I did not even try what Jetjock said and thought he was insulting me, he did to some extent, but I was new and wanted to be spoon fed which is not the way to learn about cars, I listned and learn a lot and now I am building my own engines. Sure I don't know everything but I sure do a lot more than people think I do, especially with internals.
The number one person I PM when I need help to a question is IJ. Shoots I even asked him how would a EFI engine work in a original carb car without the use of a standalone when I had no intenions of doing that kind of swap.

Damn he was just asking about if he should take the fan clutch out or not, then u told him to go 2jz and this whole story about your 7m not working...
It wasnt such a bad question...
