So simply move that one idler pulley to the new position which there is already hole to put it in, and change from 93.5 belt to a 79.5 belt?

 

i guess. the plate didnt change, so ya if you can replicate that routing, its in your best interest to do so.

and ya 79.5 for a 3.33 pulley and 1/2" smaller for each pulley drop.

 

I have never heard of a catch can collapsing, how would that even happen?? I can't imagine creating enough vacuum to collapse and aluminum can that has properly routed hoses??

 

Str8 thanks for noticing and for all the info, much appreciated! I have the 3.12 but heard with the gtm pulley to add .5, so think the 79.5 should work. I sent all the info to the shop. Definitely want to make sure I don't have any belt slip when I get the car to the dyno.

 

I read this:

Not one, but multiple people had problems with the welds breaking, and it having lots of problems.

 

383HP, 335TQ @ 10 PSI @ around 11.5AFR @ WOT.
How's it look?

Im pleased with the results. Im glad Im not pushing the 400 envelope. Can always do straight pipes and 2.87 in the future.
