Well right now I have the car apart and the stock fan out so I could get the head back on with the raceware head stud kit. So I am looking to leave the stock fan out and go with a EF setup. What is the best kit to go with or any other solution?

Spal fans are great and that is what comes in the Supreme Power kit. Their prices tend to vary. I picked one up for 110 on sale years ago.

Add this for independent temp control or wire in your own on/off switch.

One more mile,

Did you notice a difference?

It has been more than three years since the install. It did improve throttle response a bit.

What does the SPP kit include?


I already have a switch to turn the stock electric fan on/off since I no longer have AC, I use it to cool the FMIC between runs.


Do you think I will need the fan to come on at a set temp if the car is only used for drag racing at the time?

I had the SPP EFK on the car and I did feel a difference when it was on. Better throttle response when it is on. I didn’t get a switch for the on off though. Worth it IMO

It comes with the fan, mounting hardware, wiring, and a machined pulley to replace the fan. The instructions have the wiring spliced to the other fan. You would probably want an on/off switch so you could know it was off for the run and then flip it on and run it until you stage again.

The electric fan moves more air than the stock fan does at idle. That helps cooling in the pits or paddock. On the other side of the tach we see another benefit. You're not spinning a stock fan at 8500 rpm anymore. I don't know how much energy it takes to spin a fan that fast but I bet it is significant. The electric fan just spins up to it's efficiency sweetspot and starts moving air regardless of the vehicle's speed or rpm. The alternator is already spinning and is more than sufficient to charge the battery so the energy the electric fan runs on could be considered surplus.

Mike,

Why are you removing the head. Did it lift with the stock bolts?

Yeah it shouldn't be a problem seeing that I already run the stock electric fan with a relay/switch so wiring another one to come on at the same time will be easy.

Mike at PureMS ended up ordering me a shorter belt so I dont have to run a pulley in the stock fan location at all, so I will have to do is order up a fan that will fit and mount it.


Mike,

I think thats what happened when I ran 134 mph at fontana.

Install instructions. You may be able to source the same fan for much less and just splice it in with your existing fan. No sense buying parts you don't need. I don't think there is all that much mounting hardware.

I will most likely just end up mounting the fan directly to the radiator and then adding a adjustable temp sensor control on top of already being able to turn it on with a switch.


Here is what I am looking at ordering.

you need a VERY slim fan...

i had the 14" SPAL that came with the SPP EFK...

also, if only for drag racing, just wire it in to your current on/off switch... no point in going crazy with a thermo switch, if you know when youll want it on and off anyways....

I went the DIY approach, got a shorter belt and removed the old hub assembly, I'm sure thats worth at least 1 HP right there.

I got a fan from Jegs, cheap Mr. Gasket 12", flows 1400cfm, 3" mounting depth, fit with no problems - http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_744363_-1_10117

I'd go with a Spal if I had to do it again though, and probably a 14"

I also got a lower temp fan switch from neuspeed, forgot what the temps were though.

You probably don't want it running while you're blasting down the 1/4 mile anyways, so the stock fan switch with a manual override is more than adequate.

The fan I am getting is 3.25" thick so I shouldn't have any clearance issues mounting it to the radiator.

Fan Diameter (in): 14.000 in.
Height (in): 14.750 in.
Width (in): 14.000 in.

thats a good set-up mike, pretty much the same thing that we run on my dads corvette race car

Thanks. I will make sure to take plenty of pics when I put the fan setup on. For the mean time the car will be without the driverside fan but I still have the passengerside till then. I hope to have the fan on before the SCE event which is in 2 weekends. Then it will be off to the dyno(dynojet) and then a few of us plan on heading back to SAC raceway, well thats if those JHM boys get their cars up and running by then.[;)]

there is a shorter belt you can run so you dont even need that pulley there.
i know the part number is somewhere on this web site for the belt
but if you cant find it let me know ill go look at mine if you want

Its already on my car, mike at Purems ordered it for me this morning and actually put it on my car when it showed up at 3pm since I wasn't there.

bitter and I installed mine when we did my tbelt. It was the SPP EFK kit that came with the pulley. we just removed the old fan and mounted the new one in place with the supplied tabs. I can't say I really noticed a difference though...maybe a bit of perceived throttle response improvement???

the temp control switch would be a nice addition too.
