This is cjmatts old car, i had a ton of problems with the cog setup that was on it and bracket flex, so i did some changes. Made a dual plate setup for the blower to stop the flexing. Added a Tial Q BOV in place of the vortech Mondo, no more problems with pipes blowing off and compressor surge. Also switched from the 30mm cog drive with 68/26 pullies and 3" single bearing tensioner that kept shredding teeth off the belts and was just not able to take the stress. A 10-rib setup using a 7.8" crank which required some machining to work, 3.25" dual bearing idler which is a manual tensioner, and a 3.12" blower pulley are now installed. Belt length ended up being 44.5" which is the only size available in that area ($41.70), but it fits perfect with this pulley, i can do a 2.95" on the blower the way i have it set up, or could go with the 3.33" if i wanted. I need to move the tensioner slot on the plate a bit to get extra adjustment for any more options. Once this change is made i think i can get the 3.47 and 2.75 to fit all with the same belt, the next set of brackets i will move the blower 3/16" out to take up the belt with the small pulley. If the 3.47 doesnt work so be it, no reason to use that big pulley with this blower anyway. At any rate i have gotten around 350 miles on this setup already and its awesome. I have no belt slip, i even loosened the belt a tick yesterday to take some stress off the crank (can turn it 90*) and it still hasnt shown any slip. I am going to really lean on it and take some vid this weekend, but thus far i have seen 11psi but its hard to watch the guage! I think im gonna make a couple sets of these to order later this year (cnc plasma cut) if anyone is interested as well. If i recall this should work with s, t, and ysi correct?

















And some idle vid with the BOV and a quick pull i made, camera died after this. That BOV is fooking loud

Nice. I like the brackets and manual tensioner.

 

Looks good Gary! We look forward to seeing some numbers from that beast

looks and sounds nice. glad to see ya got that 2 bar setup working!

 

yeah the 2 bar was a real pain in the ***, but i have it down pretty good now. Gonna make a couple changes again this weekend and should be able to go closed loop and be done enough. Going LSx ECM for next year so im not gonna waste much time on this POS
