bvfd_gordo Posted August 26, 2010 Report Share Posted August 26, 2010 Mike I ran stock pulleys on my 305 and 350 only time it would throw a belt was when the belt was worn or pulleys not in line. If you are not taching over 6000 rpm's it should not throw a belt. Do you run an underdrive belt? Link to comment Share on other sites More sharing options...

dancer52 Posted August 26, 2010 Report Share Posted August 26, 2010 short reply.....stock pulleys are a crap shoot...if you can run aftermarket..do it...the grooves are deeper and there tolerance is tighter. Also..make sure your running a 3/8 wide belt...they sit in the grooves better. I hate stock pulleys... aftermarket pulleys are much cheaper than an engine...and with a kid running the car..I would not count on them using common sense and pulling off..EVER..lol I know...mine dont.

AJ i dont know if my boy is just that tallented .. or crazy .. but he drove this car for ten laps or so at cc .without power stearing . the stock stearing wheel is 14 inches and worn plum out .....i lasted two laps in this car last year .and was tired when that belt came off ..... i has stock pulleys ..and another thing i didnt mention .. the belt goes around the water pump as well ..thats why it got hot .he lost both items ... as for commen sense and not pulling off .. YOU GET AN A .. but then all rookies including us when we started would not pull off .....i blew up four motors . for not pulling off ..this one maybe burnt .... but have a exstra we can build ....for next week ..... ... i told him yesterday ..now that you have gone foot down .. and had your go anywhere on the track excersize ..its time to slow down and learn to drive ...... i will add a light to the dash .. dont know if he will pay attention to it ..but i will ,and have him black flaged ...lol i know he see.s the flag man .. he heeded the move over flag everytime .........

THANK YOU AND DY 97 .......BTW JUST GOT THAT CAR LAST THURSDAY AND SPENT MOST OF OUR FREE TIME .GETTING HIM FITTED ..... if you do have the money then yes aftermarket is the way to go.. if you dont.. run a seperate belt just around your crank and water pump.. this way if u do sling the power steering it wont get hot and run your powering steering around just the crank and power steering.. with 2 short belts you have alot lower chance of slinging them Link to comment Share on other sites More sharing options...
jwmbishop Posted August 26, 2010 Report Share Posted August 26, 2010 Unless the belt you sling wraps up in the others and takes em all anyway! Link to comment Share on other sites More sharing options...

DirtRacer9s Posted September 7, 2010 Report Share Posted September 7, 2010 Having the belt wrap around both the water pump and power steering can be a good thing especially for a rookie. If it looses the power steering that means you need to pull off because you no longer have your water pump either. Just a back up plan if they forget to look at the temp guage. Just a thought. Thats how I do it. Link to comment Share on other sites More sharing options...

Thats how I do it. man how we know all aboult that ...forget to look at the temp gauge .... seeing he had neither water pump and power stearing ..and his first night with big eyes .and exsitement.. ..and now it is comeing out .i suppose 400 degrees or so .may have helped in its retirement do you think .....gave her onelast chance to survive another night .. .. cost him a couple of posible wins. so a throw together may make it this weekend .
