What's the scoop on this new Pro Systems SV1 throttle body style carb? Looks very cool!

I've had one on my 545  for several years now,  the newer versions seem to be doing a lot better than the early  models.
I had mine back to Patrick  3 times,   it killed plugs at idle like nothing else I've ever had..  The third time  the main body was replaced with a new one with all of the improvements.  Huge difference,  it's much more responsive to adjustments now.    A very frustrating experience at first but from all of my dealings with him, Patrick stands by what he sells and took the time to make it right  and I'm very happy with it now.

I was thinking of trying one of these myself. Glad you brought it up. I can't find much feedback either.

Decent amount of feedback on yellowbullet and they aren't generally liked. Majority put a dominator back on and pick up et, so I read.

Some certainly like it.

bbcoupe (with the 3900 lb Aussie Falcon - 545 with 255 radials) went 10.43 @ 133 mph. Not too bad for a mild solid roller effort with an SV1 on top.

I agree with you, his car does run well and he definitely seems to like how it runs. That said, most of the reading I've done on YB leans toward users preferring dominators.

No personal experience here Cool

Yeah, there's  been  some very heated back and forth over them  on YB,  I don't go over there very much...

The newest models have updated metering blocks, I haven't upgraded to them, although  I did buy the shear plate.

Still no passes since 2012,  looking forward to finishing up some other projects  and get it back out again.

I'm hoping for mid 10's,   myself,   the best I've done  is 11.10 @ 124.6 mph...

I haven't seen anything about it recently online  other than it was sold a while ago,  but  the guy named Frank with the green Torino wagon  "Torinosaurus"  had one on his motor also and was running pretty well..
