Can anyone tell me if the Craven 15% reduction pulley works well, and if it has a lip on it that helps prevent the belt from walking off? if there is a better pulley that can be suggested, please do tell.

 

Great pulley, been running one for a couple years with zero problems!

 

Did you need to go to a spark plug that was one grade cooler?

 

You need to cooler spark plug.

 

I did, one heat range cooler.

 

For a 15% you can run regular plugs. I know many folks that are using stock with no problems.

 

If the pulley is aligned properly, you shouldn't have to worry about the belt walking off. Both stock and -1 ranges work fine - the best choice for you depends on your driving habits.

 

Might also depend on what gas you use. I've got stock plugs and generally use Arco gas, I get pinging under heavy loads. I am currently running Chevron to see what happens with the pinging. My long term solution will be colder plugs (Brisk).

 

Had ours for a year now with no problems and it does fine with the stock plugs. Nice improvement!

 

Minibiker-

Our stainless steel pulleys do not have a lip, but if you request a black pulley, it will have the lip.

 

Just installed mine, with the cooler plugs - absolutely LOVE IT!

 

Mine just came in. Yahoooo. Went to get the belt today that's a tad shorter, plus the Iridium plugs one step cooler. Will do this Saturday early AM.

 

Hey, is the pulley a tough job to do ?

 

An hour for the pros, 1/2+ day for shadetree.

See Randy Webb's How-to https://www.northamericanmotoring.co...8-how-tos.html

 

I got it down to about 1.5 providing that I have the tools ready. For someone that hasn't done it, give yourself 3 + hours.

 

Actually waiting until next weekend now. All my tools will be ready. Are there any Stars head tools required? Or all just metric hex bolts? Oh yea thanks to all NAMmers for the help !!

 

Uhh you really need to go to a colder grade least i did with the 15%
I mean you can run it but I found the car alot smoother and more driveable with the Brisk cold plugs.
Just my personal deal you know?
the cravin is a good pulley i know danny from mini corsa reccomends it.
I personaly have the Alta V1 and dont have much of an issue with it.

 

Metric hex, cross tip screws and special tools (jack stands/puller and such).
