Default Sold the GT91-What twins for my STREET driven 404

So I just sold my GT91 because Ive decided I want to go with twins since this car will see alot more time on the street than the track.

Motor is a 404ci ls
lsa heads
holley hi rise
cam will be spec'd by liljohn
9.5 to 1
internals should be good to over 1200hp

my goal is to have a highly responsive setup that will put up big numbers for the track but still have good street manners, probably try and keep it around 10-12lbs of boost on the street and 18-20 for track. car should weigh in at around 2900-3000 and hope to crack off a mid to high 8 second pass

No class requirements
Im trying to stay under $800 a turbo

Heres the ones ive been looking at.
BW s366 66/71
Turbonetics TC70 70/68
Comp ct3 6765

At this point I really like the bw just beacuse i know they are a super durable unit and the price is on point, my only worry is spool.

Curious to see what the experts say

heres an option above for 7.96 at 180mph,,thinking with your motor you really dont need boost on the street ,pretty stout as is,then in boost run 180mph..

good luck in what ever you decide..

I run a gt91 on the street and I am very happy with it. Its very responsive and spools quickly. Its a shame you got rid of it.

What's the spool time like? How many miles have you put on it?

Spool time with a circle d 3600 in my 4l80 is almost instant. I am very happy with it. I have about 1000 miles on it and counting. I only have it on 12psi now. Going up soon.
