super sucker
 

Awhile back there was a discussion about carb spacers . I went to the dyno yesterday and i ran my open 1 inch spacer made by transdapt and then i ran a 1 inch super sucker spacer.....well i was shocked as the i lost 14 hp with the super sucker over the transdapt.........we did 3 pulls with the spacer with same results...

I honestly am not suprised I've used the super sucker before with same results. I still am liking this one

That sucks. :P

What intake did you use ?

super victor

Just curious, we have seen some spacers actually loose power, the only thing we can think of is there was enough or to much plenum volume.

The transdapt spacer by hamburger is a nice spacer, we have been using this spacer as well and see 7-10 hp gain on most builds.

What kind of power did you engine make ?

My builder just got done with my motor today and about the last thing I have to buy is the carb spacer and I am at a little bit of a loss here. This motor has to sustain 7600-8000 rpm for 12-15 seconds.

My motor is a BBC 540, 14.2:1 comp., Dart 355 CNC heads, R.M. CNC Super Victor intake, 1200 cfm Pro-Systems gas carb, cam is 799 & 765 lift w/ 284 & 294 durations @50, and a vacuum pump.

Any guesses on the hp and tq?

I made about 12hp and smoothed out my powerband when I used the 2" wilson manifolds tapered spacer vs. 1" open spacer. But I'm running a standard victor jr on a 434, so I think my motor wanted the taller spacer.
