Worlds Fastest Comanche

Just a plug, they put a story about the Bonneville comanche on this site, here is a link http://www.myrideisme.com/Blog/land-racing-jeep-commanche-yeah-you-heard-me-a-jeep/ Really not a bad place to post pictures and information about your Truck ( unless your name is Jake and you don't own a truck) Thanks

It does look good, and the price is reasonable. I have used the 1 ton Chevy stuff on other trail rigs, but the tapers were bigger than the Jeep tuff, so you had to reem everything out. This looks like a nice solution. Parts Mike sells the chevy setup for $250, but he will make custom lenghts.

Heading down to Maxton to try out the Bonneville truck. if you are in the area stop buy. Deatins on the ECTA website http://www.ecta-lsr.com/

We were having some problems with the toe changing when the body lifted on our MJ. The factory linkage is kind of a wishbone setup, and probably not the best. We decided to change to the setup used on the YJs where you have a solid rode between the tires and a link going up to the steering box. The toe is set with the solid rod and will not change with body movement in relation to the axle. I used parts from a 90 YJ, you have to purchase the tie rod, the end on the drivers side, the adjusting link for the tierod, and a new rod to go from the tie rod to the steering box. You can reuse two of the existing ends. The part numbers i purchased from Rock Auto were MDS1050 MDS1051S MES2322L MES2323S I think it ended up costing me about $100 to make the change.

I picked up a Cherokee for $200, but the engine block is cracked. Looking for a replacment engine not too far away from Northern Illinois. Would prefer a 90's motor if available.

I put a facebook page up for the Bonneville truck, just search for "pages" and type in "comanche" Tha actual name of the page is "comanche LSR 3" I know i will probably get a bunch of crap for this, but look at it this way, anything that helps promote Comanches is good.

Here is a link to a company selling the side ground effects, also a great picture of the factory eliminator package. http://www.groundeffects.com/ge/jecomanchee.htm

Found this link , it has dyno curves, etc. Maybe a 5 banger would be a good swap? http://www.nc4x4.com/forums/showthread.php?t=50703 Just a thought on the ecotech, if you can get them in a bone yard for 500-600 $, maybe they are disposible. Blow one up, buy another! Here is a gerat link on what bell housings work with what engines and will adapt to an AX15. http://www.jeeps-offroad.com/showthread.php?t=4740

That is a v6 motor i believe? If i were to pick a V6 i would go with the Chrysler Phoenix V6 that they will be putting into the Wranglers and grands (2011 model year) . It is 270 hp with no turbos here is a link http://www.allpar.com/mopar/phoenix-engines.html The whole point of the thread was to find a afordable swap that would get you more hp and less weight. Using a newer motor would probably be way more expensive than a $600 ecotech. I am looking at the cost to build a stroker motor and add some performance modifications (about $3,000) So what else could you do for $3,000 to get you an engine that has maybe more preformace, less weight, and better gas mileage.

What do you think of the LL8 motor, do you hate that too?

I think the inliners board has a thread on this, some guy is making a new oil pan with a rear sump. The 4200 or LL8 motor was used on the trailblazers. My wife has one in her car, great motor 270 hp and 18 mpg around town in a heavy car. the torque curve is really flat. I they cost about $1,000-$1,200 in junkyards, so the price is cheaper than a turbocharged ecotec and a ablut double a non turbocharged. There may be a height issue in an MJ. The DOHC setup makes the engine very tall. I like the ecotec because of the light weight. the LL8 motor would be less weight than a 4.0, and probably the same weight as the 4 banger. The less weight you have the faster you will be off the line. Both engines offer about the same hp ( if you compare with the cobalt ss motor). the 6 has more grunt with peak torque being at a lower RPM Here is a link to the ll8 info http://en.wikipedia.org/wiki/GM_Atlas_engine#LL8 I think the big issue will be total cost, if you buy a motor for $500, than a bellhousing cost you $300, wiring harness $500. Computer $150, custom motor mounts ?? Exhaust work? I think $3,000 or so before you are done. I think the decision between the LL8 and the Ecotec would be made on how much performance you want in the end. Lots of performance stuff available for the Ecotec, not much for the ll8

Well, i guess everybody has an opinion. The Ecotec is now a mature motor, and allot of the early problems have been corrected. Will it go 250,000 miles like a jeep motor? probably not. The ecotec has been used in drag racing and land speed racing. the 2.2L turbocharged drag version puts out 1,400 hp so about 500 hp/L the same engine was downgraded for land speed racing and only puts out 700 hp Probably continous service at 350-400 hp is ok. the Cobalt ss is rated at 260 hp ourt of the box, and chiping it can put it over 300 easy. As for the gauges, if you put it in Comanche, most of the gauges are not run from the computer. Solutions are availble for standard transmissions, but not much for automatics. you could go with a GM non computer automatic (700r4) The first ohv 4 cylinder in the jeeps was the GM iron duke, and the first year of the comanche they put a chevy V6 in it ( also a french diesel). The J trucks used Buick 350 motors, and prior to 1972 the Buick v6 was an available option on the CJ. No mater what motor they had, they were still Jeeps. The engine is a DOHC, 4 valve per cylinder, cross flow head. Direct cylinder injection versions are also out there. here is a link to more information. http://en.wikipedia.org/wiki/GM_Family_II_engine#Ecotec

Too much time on my hands these days, and i was thinking about cheap engine swaps for Comanches , especilly the 4 bangers. I guess if you have a 4 banger, the quick and easy swap is to go to a 4.0 l or Stroker motor. Not bad, but gas mileage could be a issue. I checked boneyard prices on the Ecotec motors, you can get a good late model motor for about $500 and the turbo version for about $1,500. the bigger gas version is about 175 hp, same as the original 4.0 and the Turbo version is 260 hp. the engines are way lighter than any of the stock power plants. Much more engineering in these motors (dohc, 4 valve per cylinder, etc) There was also a supercharged version that was 205 hp, these are usually around $1,000. GM used a Asin trans in th solstice, so you can get a bellhousing from GM. Anybody got a 4 cylinder truck with a tired motor and a couple of grand and wants to give it a try? Just a note GM does offer the HT 3.4 motor which should bolt to the 4 banger trans for about $1,800. It is only 160 hp and it is still an antique design, No efi, carb only 4.0 would be a much better choice then this.

You are correct, 175 is slow for that class, He is in the 350cid class and the current record is 210.473 It probably takes double the HP to go from 175 to 210, so he gave up and decided to drag race the truck. This is a bad class because you can run the 360 cid nascar motors in it. You can't really got more high performance than that. I found an article last night on the 1990 cyclone truck. It had a version of the chevy 4.3 bored and stroked to 5.0L it put out 563 hp @ 8000 rpm It had a allot of trick stuff on it. that truck went 210.469 mph

I have seen it, but does it really count if you put a Chevy V8 into a Comanche. Maybe it should be called a Comanchevy. I run in a production class, he runs in a Modified class, because he is highly modified. Mine is all Comanche!

Ok here is a link on this site for all of you who don't want to log on to the Stroker site http://www.comancheclub.com/forums/viewtopic.php?f=7&t=23150 But it still is not a bad idea to look around the stroker site. I think it's a good idea to put a 270 hp stroker in an MJ, A stroker costs about the same as a rebuilt engine. The Comanche club site is great, but it is a little light on big performance upgrades.

Peak torque was about 410 ft/lbs @4,500 rpm. The torque curve is basically flat, and that is more important that peak torque.

Here you go!

I will get it up on photo bucket tonight, you could always just join the stroker site!

We took the LSR 3 down to Hesco this weekend while the LSR 2 was being auctioned off in Michigan. We dynoed it. You can find the final run here http://www.jeepstrokers.com/forum/viewtopic.php?f=5&t=739&start=15 near the bottom of the page . Anybody want to race?

Hey guys, how about comming out to Maxton on May 23 to cheer me on, see the post here http://www.comancheclub.com/forums/viewtopic.php?f=8&t=22676

I am not sure what the fees are going to be this year, but in past years a day pass was $10.00 and a week pass was $40.00 If you become a BNI member, which costs $70.00 you get a week pass , news letters, poster and a rule book. here is a link to the SCTA home page http://www.scta-bni.org/

I'll buy you a Beer if yo go over 110

They run a top speed challange at Maxton, somthing to do with Hot rod Magazine, if you go less than 120, no roll cage is needed. Check out the Hot Rod magazine site.

If I had the money, I would buy it, If sombody else wants to buy it and needs a place to keep it, I can store it for free. It is probably a great used truck if you pulled the roll cage out. The engine is special as well as the computer. It does have some rust form the salt, and the front suspension is modified. It is a 2wd and only a dana 35 rear. It is manual steering and manual brakes, so you would have to do some work there.
