Re: Mods for the Adventurous Experimenters

[QUOTE=amw5;628506]Never heard of the TCI unit on a 5.7L...doesn't mean it isn't good, just don't know anyone running one. The chevy guys like to run them, so they're probably well made. The SLP/Powerbond pulley is a proven performer on the hemis. However, you should give the TCI a try and let us know how you like it, IMO. As long as it has the lip on the back to keep the belt from slipping off, you're good to go.
QUOTE]
well, i've been looking and that tci doesnt have much info out there. the place i linked has NO description for it. Summit also sells it, but it says "pulley included" I'm not to sure about that. I might just get a SLP- lots of good feedback on it. Unfortunately, thats all i'm gonna change A.T.M. My XJ decided to crap out on me - collapsed a lifter and when i pulled the vc, shiny metal "glitter"....everywhere

Re: Mods for the Adventurous Experimenters

Been thinking these are SFI rated,but
quick question: do we use the car or truck pulley?

Re: Mods for the Adventurous Experimenters

Probably the car ones, since the Jeep uses the LX motor.

Re: Mods for the Adventurous Experimenters

Did it come with a new crank bolt? If not, it should be changed.

Re: Mods for the Adventurous Experimenters

Well,i finally got this done! I changed to a 6.1 tensioner (just to be safe) new waterpump,changed the oil,and THE PULLEY.For the sake of comparison, I did NOT clean the TB, air filter,seafoam it etc...
I live about an hour from wichita,ks . the last time we went,with a 75 mph hwy avg and a bit of town driving the evic showed 15.4 mpg. last nite we went with the same 75 mph cruising, and a bit more in town driving (and yes i hit it a little bit) but this time the evic showed 15.8 mpg! I know thats not much, but it IS better. My plugs are due for replacement, but i wanted to get a good idea of what just this pulley did,before changing them. Oh and it revs quicker too MUCHO BEDDA!

some pics: 5.7 tensioner- note the 2 "springs"


and the 6.1 has 4

the pulley was a pain,had a problem with the bolt threads, but big difference

if anyones gonna do this here's the belt you need

Re: Mods for the Adventurous Experimenters

I didn't realize you were going to pull the front cover too. I would have recommended you advance the cam while it was apart. Would have been easy to do and, I still say, it would make a fair difference on an otherwise stock engine, especially in the low/mid ranges where it's driven most of the time.

Re: Mods for the Adventurous Experimenters

I was thinking about it, but i plan on spending good time at the track,at high rpm's. No doubt it would be very helpful around town and help mpg's as well, but i LOVE to romp on it.
