Who wants aluminum rad for $210

[selfinfliction]

I just read this whole thread and here are my thoughts:

1. Electric fans suck balls if you're in any kind of warm climate, I haven't seen anything that tops the stock clutch fan. If you run a DECENT electric fan then you have to upgrade your alternator and pray that you don't get stuck in stop and go traffic and your fan doesn't outrun your alternator at idle.

bad assumption, my 16" knock off pro comp e-fan did 2500cfm @ 13.* amps. if your altenator will not support that, the electric fan should be the least of your worries.

plus, removing the approx. 5 pounds of rotaional mass from the drivetrain will be a big difference. hoosier advertises for every 10 pounds of rotational mass removed, the car will respond like it is 100 pounds lighter.

WTF are you talking about??

An electric fan introduces more failure points into the cooling design of this car than there was to start with, not even counting the fact that the car wasn't designed for one anyways. If Toyota thought that the E-fans would work better, they would be one there, same goes for a 2JZ.

E-fans may cool more at Idle (if you have big ones and your stock fan clutch was in need of a rebuild) but they pale in comparison to the cooling ability of the fan clutch when giving the car hell. Tell me this: which is easier to keep running for at least 15 years? A hydraulic fan clutch that will only need it's fluid changed out about every 5 years to keep it running top notch, or an electric fan, that has been wired into the car by the owner, thus introducing several failure points in the design (care to search on here how many user's have lost a motor over E-fans? And I'm not talking about Gumby-Dumb-Fuck next door, I'm talking about competent builders who have rebuilt their motors and are making large amounts of horsepower.)? Who knows? You may be an electrician, I don't know nor do I care. I'm just advising you of the proven facts that have been posted on here previously.

So I guess what you were trying to get at in your post was that you would rather sacrifice a proven cooling method for this motor over a slightly faster car (according to your bum dyno)?? :3d_frown:

 

[selfinfliction]

a few points on your post...

it's not a "bum dyno" efans will free up hp, that's proven, i was referring to how the car acts, because dynos should only be used as tuning tools, not accomplishments.

as far as indtroducing more failure points; any part added to the vehicle that adds hp, also adds more possible failure points.

i searched for a few minutes and couldn't seem to find a large amount of people as you were insinuating that have "lost a motor due to e-fans" AND if they were because of overheating, was it because of inproper installation or just a lack of knowledge on finding the correct product for the application? like a single ebay 14" efan on an oem radiator with no shroud installed.

if everyone was worried about their car lasting 15 years, they wouldn't be running larger turbos either, now would they?

there's been plenty of guys in the mk4 community as well as the mk3 that have run top of the name brand e-fan setups most as the kit that was made for the car, once making power they fail because they can't supply enough air.

Even the glorified ford taurus e-fan can't keep up. now having a small pusher fan for idle i do believe in. Believe it or not on the supra's your doing damn good if you can pull out 3-4hp just by swapping out fans.
There was a fellow that tested this theroy on a 7m years ago and got a 2hp difference.

e-fans are decent for midly modded stock turbo supra's and possibly upgraded ct supra's..

btw you probably couldn't find them because the site has been hacked and gone down a few times, try supraforums for that info plenty of it there.

btw there are vehicles lasting longer than 10 years on larger turbo's....

selfinfliction, go out to a road course and run your car with electric fans.

Talk with the other guys in the pits during sessions who are stitting there waiting for the car to cool down so they can run again.

Scratch your head and wonder why all those other guys are still going around the track.

In my 1,200 + RWHP drag car? Electric fans - every HP counts, and the total engine run time is a couple of minutes per run.

On my road course and street cars? Belt driven fans. Where reliability, longevity and the ability to dissipate heat over more than a few minutes matter.

I have yet to find electric fans that are up to the task when you actually look at things like oil temps as well as coolant temps. Or consider running the car hard for more than a few seconds at a time.

When you look at the minuscule amount of power that you are talking about, unless you are racing professionally in a sport like drag racing where a few 100ths of a second can make a difference, it's not worth the tradeoff for reliability and overall cooling efficiency.

I've been doing this for a lot of years (probably 25 years in racing and about 17 years specifically with Supras), and this debate comes up over, and over, and over. And everytime, the guys who have the cars that last, and can be run hard for extended periods of time, they always have a mechanical fan.

Just my $.02, your mileage may vary...

I have no need to further support my claims, they have been backed up with people who have more experience with racing, building, maintaining these types of motors for longer than you've possibly been alive. As far as motor failures go, take some time and dig a little deeper for curiosity's sake, there are a few on here still.

Not everyone who upgrades their cooling system is running larger turbos. Why do you assume that everyone is here to build the motor to make power? You'd be surprised by how many on here have a near stock car and are plenty happy with it and plan to keep it that way .

Ok folks - enough of jacking up this poor guys thread. This thread is not efans vs belt fans.

It about a $210 radiator group buy.

Let's get back on topic.

 

[Rennat]

Do you have a target time period when they will have produced them? I dont want to be told the radiator will be done next month, and then told i have to wait another month... and another month... just curious.

 

[88mkIIIproject]

I'm in for a $210 radiator, hopefully you can get a group buy organized soon!!

 

[Mk3runner]

any new info if the hydro fans and fan shrouds can be used with these?

it seems this is the primary question we all keep asking.

Lol, i was just about to say.

Release date that i've been reassured time after time is in 2 more months, so March.

The MISHIMOTO RADIATOR group buy is officially on!!! Look at the following thread and discontinue use of this one!

So will the hydrofan work with the radiator?
