i have a switzer s300 that i am sending to bullseye power to get a race housing put on it.
the turbo currently a 60 mm cold side with a 110 hot. i have HBP S4 motor and was getting great spool by 3200 RPM.
i would like to get some more flow out of this turbo anyone have any suggestions for this turbo
bigger wheels?
any special housings?
thanks

 

Rather than getting bigger wheels, you would be better of selling it and getting something like a 62 or 66mm compressor. You have the 1.10 turbine housing on yours? That would be a big on the S4.

 

Agreed. Sell it and move up to a unit ~66mm from Borg Warner, Garrett or Turbonetics.

 

hows the spool time on somthing like that?

 

Depends on the turbo. You could also move to something like a Precision 6265 that spools quicker than a 66/67mm but makes power like most of them. A 66/67 will also make a ton more power than a 60mm.

 

well i have a bullseye s372 with a 4inch exhaust and am seeing about 12lbs at 4000rpms on a rough tune in 4th gear. I just got the car on the road and its sick, cant wait to get it on the dyno
