After seeing what kind of power you guys are putting down, Im thinking of going as big as possible this time. I had planned on going with the T trim, but after talking to Vortech I can get the YSi for about $200 more. The only difference is that the YSi trim would require the mounting bracket to be modified.
T trim
Straight cut spur gear
Fits engines up to 825 horsepower
Maximum airflow: 1,200 CFM *
Maximum boost pressure: 26 PSI *
Maximum impeller speed: 55,000 RPM
Adiabatic efficiency: 73% **
Available with straight or curved discharge and clockwise or counterclockwise rotation
YSi trim
Fits engines up to 1200 horsepower
Maximum airflow: 1,600 CFM *
Maximum boost pressure: 30 PSI *
Maximum impeller speed: 65,000 RPM
Adiabatic efficiency: 78% **
Available with straight or curved discharge in clockwise rotation only
What do you guys think? What do you think it would cost to have my bracket modified?

 

YSi My bro has one on his stang and that blower is sick. Much better blower that the T trim with lots more room for growth.

 

Its time to order some pistons and rods now.

 

I'll be going with a 9:1 forged 364 and a 4L80 most likely.
Anyone have any ideas as to who I could go to for the bracket modifications and a price??
Im curious if the bolt pattern will be the same or if every thing will need to be changed.

 

Damn green you are getting serious.

 

Thats what i was thinking...these trucks are getting nuts lately...stock ls1 cars have to be carefull now.

 

Im just tryin to keep up with you turbo guys I guess I'll give Vortech a call tomorrow and see if they can tell me anything about the physical differences in size and mounting. I know that the inlet and outlet are quite a bit larger, but that shouldnt make too much difference. I may go with the T trim if Im looking at $1500 for the bracket as I believe some of the F body guys were paying.
Id rather stick to one power adder, but I will probably get a wet kit if I have to stay with the T trim.
