Wow, just stumbled onto this thread, and I see everyone else on here already knows me!
Thanks everyone!
I would love to see what the S374 does, but it is much more along the frame of a GT42R, and would require me to do some extra modifications to try one out.
Personally, I think -- More power to you! Run one and post up the results -- it is all about trial and error, and sometimes you get lucky.
As for streetability -- I think that my GT4088R is extremely streetable. I normally have it setup for street driving with fast spoolup (modified ignition map for early spoolup), resulting in up to 40psi+ of boost reached by 4000-4200rpms, and the insanity ends at redline (set at 8500rpms). For the track, I change my ignition timing back for slower spoolup since I am using a 2-step without anti-lag to build boost at the line. Even with the slow-spoolup ignition timing map, I see full boost around 4500-4700rpms.
The car has currently put down 753AWHP/713TQ @ 40psi peak, falling to 35psi) on a new DynoJet AWD dyno at Beyond Redline Performance in Green Bay, WI after changing over intake manifolds.
It hasn't been to the track yet, but the previous numbers were 741AWHP/696TQ at 49psi peak, falling to 42psi; on a DynoCom AWD dyno (also at Beyond Redline Performance), and track times of 9.96 @ 143mph with a best MPH of 147.88mph at 35psi on Q16 fuel in a 3200# street car on Hoosier QTP slicks.
At 30psi of boost, the old intake manifold (magnus) vs. the new manifold (Beyond Redline)
made an additional 108.97 HP and 74.23 TQ with just a manifold swap. The car now makes around 635AWHP at 30psi on Q16 gas.
New Intake manifold numbers:
30psi = 635AWHP/590ish TQ (can't remember)
40psi = 753AWHP/713TQ (boost falling to 35psi at upper rpms)
50psi = ??? -- hopefully around 825AWHP or so.
I really like the Garrett turbos, especially my GT4088R. I definitely would love to see some more numbers put down with these Borg Warner turbos though. It might be worth checking out!
As for popcorn eating..., I am currently on Transmission #16. The car will be back up and running by next week.
My goals for this turbo is to put down solid low-9's, and 155mph trap speeds.
