Hey all,

I'm looking to keep my 2000L relatively 'stock' and at this time I'm ruling out mods such as a chip, 4# pulley, nitrous, etc. I just don't have the desire to make my truck a member of the 12 second club...yet!

The next mod I'm looking to make is the E-fan with Cobra R water pump from JLP.

Are there any adverse effects this mod could have on the electrical system of my truck? Does this mod really improve gas mileage and bump horsepower up slightly?

Has anyone ever dyno'd their truck before and after e-fan installation? Or have track results before and after?

I want to keep my L relatively 'truckable' as I use it ocassionally for towing and hauling stuff. Thanks for your replies!!!

 

I have both on and I noticed the temp did go up alittle when I switched to the fan and pump.I went to a 160' thermo and noticed a nice drop on the dummy temp gauge,after the fan and pump install It seemed to go up to the old mark,just wonder if the pump doesn't move as much water.I have the fan set to a toggle switch,I only use the low setting which you can run on a 30 amp fuse,high setting needs 40 amp,low moves plenty of air.plus when you want to run someone shut it off.and its nice at the track to leave on between runs with the truck off.

 

I can't tell you how the JLP fan will work, I have the JDM fan and it is one of the best mods I have done.

 

if you want power dont bother with the fans, its a mod that most of us use when were looking for the absolute last bit. its like the single blade throttle body and a catback. its a very small peice of a puzzle.

 

I don't disagree with anything easter says above, but it will be my second engine mod (JLP filter first). Here is why -- slightly more HP, slightly more MPG, but, most importantly, quicker warmups, better temp maintenance, and no more obnoxious fan noise. I like to start from the foundation and build from there.

I would skip the so-called "Cobra R" (just a Mustang) pump though. All it does is flow less water, freeing up a couple of HP (although several tests have actually shown a loss after installing the Mustang pump). It is actually less efficient than the stock 8-blade pump.

 

That's probably because the "Cobra" pump flows less water than stock.

 

Tim, your thoughts on the meziere electric water pump?

 

thats Eaton tim, Eaton is the name. anyways i think it was your website that spoke a lot about the whole water pump thing, anyways probaly the main reason i wont switch to a cobra pump even if it gained a few HP is that if for any reasons the efans go out on the road or something, theres bound to be a place somewhere close where you can buy a stock fan setup and screw it on where with the cobra you cant.

 

all i notice with my flexalite fans is that the a/c works better and the engine revs quicker than before. gas mileage seems to have inproved a lil bit too.

 

I don't really have any. It seems like a great idea -- no parasitic losses and can be run even when the engine is not running -- but some have had trouble with the Meziere. No one seems to have stock pump failures.

So it's really too close to call. BUT, I have no experience with either. Everything I know is from reading these boards, so I'm just bench racing.

 

 

There should be more people like you in this world.


Electric fan is nice because it gives you more room in front of the engine to change lower pullies. I have the flex-a-lite fan which is lower profile than most "tuner" fans and is capable of 5500 cfm. It has performed well for over 20K miles. The cobra waterpump is not needed for this fan because there is ample space between the fan and the stock water pump. I have a cobra pump and an underdrive pulley on it and it cools my engine just fine for the last 12K+miles.

 

Didnt Dons Bolt have his Meziere E-pump pulley shear off his motor not to long go......

 

I have a Cobra-R waterpump sitting on my work bench, and Tim says it blows! About to cry but easter says his works great with underdrive pulley... I also have a set of Ruslow underdrive pulleys sitting right next to the pump! I feel better. Thank you easter.

Tim (El Esqueleto),

No flame intended, thank you for always have great input!

 

so yea save a hundred bux and dont get the cobra pump.
