The t-trim upgrade is a little more then $100. here is the link Supercharger upgrades... - ModularFords.com. it lists out the prices. One downside to upgrading a s-trim to a t is that the housing cant except HD bearings and you are still limited to 52000rpm so you cant get the max performance out of it.
And I was wrong about the price to uprade to a si trim, its only 329 and the t is 617.
You said you could upgrade to the Si-Trim for $400 and I said for another $100 ($500 total) you could get a T-Trim. At the time when I upgraded to a T-Trim it was only like $500-$550.
Why couldn't the T-Trim use HD bearings it uses the same housing? Also the T-Trim has a 55,000 rpm limit and also flows 1200cfm compared to the S-Trim's 1000cfm
