ATI and Callies.....post some info please. Posted: 12 Sep 2002 16:54 Post subject: Just talked to ATI and Callies
--------------------------------------------------------------------------------
Ok first off I called ATI today about the broken bolt in the blower. Surprizingly they gave me a RA number and said just box it up and ship it there. I have heard tons of horror stories about their waranttee stuff so this came as a deliteful surprize this morning
Now on to Callies
Well I called and after playing phone tag for a while I got a hold of them this morning. We talked back and forth about how many miles were on it with and without the blower, how it was put together, I told him the front bearings looked brand new, and what all happened to the motor when it broke. He told me that after looking at it the timing gear looks like it make just a slight score line around the crank when it was seated. Which is no big deal 99% of the time, however for some reason this time it must have just started a stress risor and that is where it broke. He said that he had never had one break like mine did and that a race shop had just called in yesterday and it sounds like they have the same thing going on with the blown Z that they built as well (they haven't torn it apart just yet). He is going to talk to Nu-Tek (right down the road from them, they specialize in LT1 motors http://www.nu-tekmotorsports.com/ ) and see what they have to say because they use a lot of Callies stuff as well. One of the possiblities is that they might start making a blower spec crank for LT1 motors with a BBC snout on it. One problem this might lead into is that a special crank gear will be needed, special balancer, hub, and the front cover is going to have to be machined as well for the BBC seal. We had aslo talked about going to a cogged system as well, and he agreed that it would eliminate all of the rolling stress that was caused by the tension on the 12 rib belt setups. The only problem would be a slight harmonic that was caused by the belt to pulley interacting together but said that as long as it was balanced (which Callies balances all rotating assemblies and cranks) there would be no problem with that at all. So they are going to send me back the snout and hub. He wanted me to do some hw on different pulley setups and how they work, the distances that the different blower pulleys stick out off of the crank and to see if we could find out how much tension that blower is putting on the crank.
We didn't talk about getting a replacement crankshaft just yet because we're still trying to figure out how and why it happened and to see if we can stop it from happening again but so far I must say Callies looks like a real stand up company that really wants to get to the bottom of the problem to make sure that it doesn't happen to you or anyone else again. Once I get some information about the blower setups I'm going to call him back and I guess we will go from there and see what he has found out from Nu-Tek and see if maybe a new designed crank is in order, if I just get a free one and start over with a new belt drive or what. But anyway at least we are making progress
I know this is on a LT1 car but I want to know how they mount on LS1 cars as well. Also are your snouts bigger than regular small block cranks or the same size? Also how far how does the crank stick out from the timing cover?
