Um ya it is different
I don't think you used the VORTECH not Vortex in the late 80's since the Company begain in 1990.......not sure why you had the problem with the T and YS do to they both were built with Heavy Duty race bearings that can support a cog system......The only failure that I ever experianced is once my oil feed line got clogged with Silicone and seized the S-trim head unit due to lack of oil......
Ok you right I just remembered was in 1991… beaus I build ASSC 1990 Mazda Miata with 302 install & custom blower bracket setup for A trim than was R trim at same time I build custom 4 link setup also for that in 1991 for ASSC.. that time I was associate with ASSC .
BTW thanks for correct VORTECH spell I was responding to you at 1AM.. So whether late 80s or 90s doesn’t matter
Same time don’t under estimate me I been around to long... I know what I am talking about
Yes it was bearing failure every Time
There excuse was to much tension on bearing …which I agree …if there is no tension on that belt will been slipping & drop in boost … at same time SN bracket were to weak or flimsy wasn’t design for maximum power… you can see the bracket flexing under boost on dyno…I have the car on dyno now with T trim setup ... it’s not just me How abut the member 2 posited after me.. Way his bearing is noisy
I send the blower just to install $30 bearing & $10 seal almost $800 with shipping
Because they have flat fee of $650 to $700 …for ½ to 1 hour worth of labor
So you are here under score in me that's cool...You are sponsor by them or you on there teem fine I can see you defending them …but I am not knocking the product down….just because I still using there blowers
I know what problem I had if you want to argue about it AL drink for that here is # 847 678 3000 thanks nile
