Flywheel Results ?

So what where your results, I remember hearing about that flywheel more than 10 years ago. Are your results better for off road or street, or both? I would like to know, tell me, tell me

and TRI-COUNTY GEAR's 10 lb flywheel weight.

AWSOME

IAT sensor cooler

O yes i did it, by the way I will be painting it black or grey. It has been working great as far as a tad more power on top end and real good on increase MPG.

IAT power Cooler

Well guess what i did or did not do. I did not relocate my IAT sensor yet, but I did raise it about 1/4 in up. I used a washer like shape made out of virgin teflon. It has great heat insolation specs. Raise my IAT upward 1/4 in and insulated it from the intake manifold which was like a hot plate. Yes grant you it still picks up heat being close to the manifold and the threads touching the manifold. But so far been running it for about 2 weeks now and has yielded a difference. I get better throttle response, it feels like more fuel is beening injected, along with slightly advancing the fuel and timing curve. Its the same science like relocation, just more on the mild side. Still warms up but does run cooler. Enough for me to feel a longer fuel spray at wide open throttle. Also noticed a increase in MPG. I use to get 35MPG on 1/4 tank and now get about 60 mpg on 1/4 tank. Sounds like alot but good for me. I will try to attach a pic.

DirtyRob a 4.0 swap would save you a lot of time and dissappointment
04-27-2014 08:13 PM
JMO69 I'm interested in doing a lot of these mods, efan,4.0 throttle body, header,injectors and such. I know gearing is best, but my 2.5 has 175thou and rattles like an SOB!, PLUS I have a spare 2.5, AND a spare 2.5 head to play with on the side while I wait for my current motor to die. It runs fine, but I figure with the rattle it's only a matter of time, so my best bet would be to get my spare all ship shape with maybe some little mods, (honed? bored?),ready to drop in.

The 4.7. It came from factory with 3.92 rears, 31s and the tow package is awesome. Even the freakin power steering has a cooler lol.

I did take off the 5 blade clutch that came with it and put on a 9 blade off a Ram 1500 . Sounds like a jet plane but I LOVE the cooling.

Currently at 189,374 original miles and still runs like a purring kitten.

Locruid Just for reference.

My wife has a 2000 Durango. It includes both a Clutch fan and an Electric from Factory.

About Aug I'll take the clutch fan off and run straight Electric. I think I have the temp go above 200 when I'm sitting for some silly reason in traffic but other than that it NEVER gets above 185. I even towed our Pop-up Trailer 200 miles each direction (with a couple good 6% inclines) and the Fan came on only once or twice in November. I usually install the Clutch fan around May but that's only cause we do a LOT of camping and towing full loads I like to have the extra cooling.

Last July with both fans, We had the A/C going, 5 people in the Durango, the trailer STUFFED and crap on top of the Durango and still never got above 210 even on the hills at 60 mph.

Yes been tossing that quick disco thought around, I do have the exact size wrench right next to me where it is handy,and your right it takes me 10 seconds to remove antenna. Thanks for that, I heard that before and hearing it again I just made up my mind not to get the quick disconnect or fold over. The HD spring alone holds up pretty good even at highway speeds and still bends under limbs and stuff. Yep with the spring its probably high enough. Right now my radio is modulating pretty good. I do need to fine tune it with a meter. Thanks

quicksand97 Yes my concern is reliability of the e-Fan, so many more parts that can go bad, motor,relay,thermo sensor and what ever else is required. I mean as it is its a job to keep my lil 97 2.5 L in tip top running condition. Under the hood its tweaked out pretty good except for e fan. Well time and money will tell. Lately I just started messing around with my old CB again and got a new 4 ft firestik, new mount, new stud, and trying to tune it with no meter. Got a firestik spring on it also. Just the good old groovy CB thing. Gonna get a new 95% protective coax cord for it next and maybe a noise supressor. Man wish I had the bucks for a 10 meter radio. Now those things put out. Anyway I have been tinkering with that. Read some interesting stuff at stus off road under reviews or other stuff page. Yea I decided to use my old existing typical aluminum L angle mount with the 4 holes and screwed it on just above the right tailight. Does not look bad at at. I think it looks pretty serious with 4ft of antenna above that. Now I need a quick disco our fold over adaptor.

I wouldn't say that is true, but it does not free up enough energy to make it worth the time or money. Belt driven fan is more reliable. Only good thing that came out of my efans was the new radiator I had to put in after the 4th failure. 1st was the Taurus fan, then the temp sensor, then a relay, then the mark 8 fan. If you like mud you won't like efans.
02-16-2014 06:31 PM
quicksand97 O yea you guys are right about regearing yields much greater results, thats been said and proven for a long time now. Yep a bit costly, I have that on my wish list to regear to 4.56 since I am a mild/partime off roader and only run 31s. Might use different gears if I decide to go to 33 x10 pizza cutters. Time and money will tell.

02-13-2014 10:50 PM
W5KVV The best thing I ever did to my Dodge 4x4 was re-gear to 4:56's. Night & day difference.

I have 4:88's & full rebuild kits out in the shop waiting to go on the Jeep.
02-13-2014 04:36 PM
DirtyRob I have seen other Jeep owners spend gobs of money trying to overcome the lack of torque and power of the 2.5
I have researched and even helped a few guys do the e-fan, 4.0 throttle body swap, intake, headers, exhaust etc. I have yet to be impressed at all.
My 90 2.5 TBI supposedly cannot benefit from the mods above, so I kept it stock. I am on 33" Swampers with 4.88's and I can keep up no problem and they are running 31" at's with the factory 4.10 gears and every "mod" we could do besides re-gear. (93-95 YJ's)
Re-gearing is the best upgrade hands down. The other stuff really doesn't do as much and costs about the same in the long run.
They can pull a hill a little and I mean just a little easier.
I am now looking into a 4.0 swap. makes much more sense to me. I don't care to do the a v-8 swap personally as most stock older motors will not give me much more power and torque.
02-13-2014 11:49 AM
Frenz thanx for the e-fan switch reccomend.. I'll use that in conjunction with my thermo sensor.

You must upgrade your wires and suggest new rotor and cap with new hotter burning plugs for the hi perf coil to operate .. if it gives the kind of results I experienced with the 750cc suzuki mc... then I'm ecstatic. I'll keep you posted.

02-12-2014 04:44 PM
W5KVV I'll try one of my Taurus fans if & when the stock clutch goes out, but I'm being realistic about it. I don't expect an e-fan to turn it into a screamer. Its still a 2.5.

With the terrain I'm going to be on, the Taurus fan should hold up.

Yeah, I do more hardcore mud stuff than most. I killed a Taurus fan super fast in about 3-4 trips. Mark 8 fan lasted longer but still died. Last one died in the woods while mudding and I didn't notice until my radiator popped. That is when I got pissed off and switched back The kill switch was for crossing deep water, but I killed it at other times to see if I got any increase in power or gas mileage but got neither.
02-11-2014 04:07 PM
stykthyn You are supposed to have a cut of switch in the cab for when you hit water and mud. I didn't really see a performance gain. Engine would rev easier that was about it.

I read in a Mopar Muscle mag years ago where they did tests on the factory rigid fans of some small block cars. The ridid fan robbed anywhere from 10-15 hp at WOT. Now, factory fans on these Jeeps aren't rigid, they're a clutch style fan, but they still create drag aka parasitic loss.

Lots of folks will say by running an e fan you're just moving the load from the water pump to the alternator. But, if your charging system is in good order, the added load on the alternator by the e fan will be nowhere near as great as the load from the mechanical fan.
I had an electric fan with a kill switch for about a year. I would kill the fan at highway speeds, but never had a performance gain from it. Went back to stock fan after killing two electric fans with mud. No difference.
02-11-2014 12:09 PM
stykthyn I've already got all the by on mods, I just couldn't justify the price of the screamin demon setup. If its what they advertise it to be I would be willing to try it.

02-11-2014 11:29 AM
stykthyn Is the screamin demon kit really worth that much over the factory set up?
02-08-2014 05:25 PM
quicksand97 Yes Sir Mr Frenz your right screamin demons coil is 45,000 volts, but I believe they cost a bit more because because of name. I believe its exactly like the one I have from CRT Performance for a lower price. But its all good. O yes on that E-Fan yes I have read its best to run a in cab off/on swicth. Sounds good guys. Happy Wheeling and take care.
02-08-2014 10:13 AM
Frenz DONE THIS ONE ... Let you know in a few weeks. Tri-County Gear has never had one returned and I keep hearing good things. we did have to do a lil grinding.. no problem. they give you everything you need for the install and so far I am very excited about this mod.
