Street Port
#1
I bought and engine the guy thought he blew the whole thing but it was just a coolant seal and the apex seals still have spring to them. Its a gsl-se so it have 3mm I'm not for shure but I assum they 3 peice seals so I can't do bridge. What kind of numbers can I expect out of a big street port using a holly 600. Does any one no if I could do a half brige with the 3 peice seals.

Racing Beat got ~225 HP from a street ported 6 port. The carb was installed "backwards" (ie carb secondaries to engine primaries) for best HP.
Yes - you can do a half bridge with GSL-SE seals. Just keep the corner piece pointed away from the bridge port.

Not a good choice unless you are a holley type of guy with loads of suitably modified carbs lying around.

The power curve on the holley was awful though. It lost huge amounts in the low end to the mikuni 44, and only caught up at 7500RPM IIRC.

I have to wonder if the Holley fell short due to being a vacuum secondary and not having the secondary actuator "perfect".

Aren't they only 2mm apex seals on the s3 13b?
tuning the Holley will require patience, but it will easily clear 200 HP (flywheel) on a streetport 13B, and you can retain excellent mid-to-high RPM power (based on my tastes)

Thanks alot everybody I'm glad to hear that 200 hp isn't going to be out of reach with a street port. Now that I know that I have 2 peice seals I might try a judge ito bridge. Does anyone have experience with the ito bridge. So which carb would be the best. Oh I have no loyalty to any carbs what ever gives me the best performance
