S/T Trim Difference?

What is the difference between the S and T trim? It looks like the T trim is the same as the S, but with greater potential. The kits are priced within couple hunfred$ of each other. I was gonna buy the T, but I don't see many people posting any info in the T forum. I know the S has been around forever and thought the T replaced it....

T didn't replace the s..the s puts out 1000 maxpsig & T puts out 1200 maxpsig..I have ran both.The T was the next step up from the R-trim..the diff is u get the low end power of the s and the top end power of th r which had to be spun to 55k..the t only has to b spun to 52k..there is daylight and dark diff in power..given a choice i would choose a T any day...The T comes w/heavy duty brgs, and is built for a cog drive(no slippage)or can be ran w/a serpentine belt.hope this helps....

Thanks for the info!
