Well I've been running S-Trim for over 5 years, and it finally is time for a rebuild, but also the perfect time to upgrade.
The current combo is
331 8.5 c/r
TFS TW 2.02s (300/230)
Cam Motion Custom (564/239/114)
Port matched Holley systemax
1 3/4 LTs
S-Trim 13psi
60lb injs, dual 255inlines, -8feed, -6 return (in work)
Alky inj
TKO600
The car made 588rw on 13psi running outta fuel at 5400rpm (on the 42lb injs and stock lines rails)
Now I was only making 13psi but spinning the S-Trim for all its worth...I ran a 2.75/7" which obviously was over spinning the S.
I'm sure you all are aware of the CFM ratings of the S/T/YS....and the reason I'm leaving the YSi out is Vortech doesnt rec. it on a curved volute (kills eff. they said) and said the YS performs better on the curved discharge.
This car is a weekend cruiser/drive on nice days to work or whenever I feel like cruising..I'm looking for a blower that will give me room to grow, and I wont have to spin it so hard. Looking for 15-18psi w/o even thinking twice, and obviously some nice CFM.
S-Trim 1000cfm 50,000 max impeller
T-Trim 1200cfm 55,000 max impeller
YS-Trim 1600cfm 65,000 max impeller
And yes this car is driven on the street 98% of the time
My goal is mid 10s
Thanks
Chris
