SU Ram Pipes\Velocity Stacks
Posted 03 June 2009 - 12:40 PM
Me again....must be getting sick of me by now.
I'm looking at getting some ram pipes for the HS6 SU's I have, and I noticed there are several on the market available. Main difference seems to be length of the pipe, as pictured.
Does anyone have any info\opinions on what is better?
I'm thinking of using the short type so that I can still fit them under my Redline Chrome filter housing, instead of buying socks.

NFI on whether this is true or a complete load of bollocks.

he had a section covering SU's and they saw a 5% increase in power with the stub stacks and a 3.5% power increase with the longer air horns. Althouh the longer airhorns did make slightly more torque at a lower rpm.
If you are running a real racetrack where you have to slow down a lot then I'd say those would be the better option, but for the drag strip, HP will win out over low end torque unless you are really hoooking hard off the line and even then increased HP will normally win. I've tuned my car both ways and it's about a tenth slower in the 1/8 mile when tuned with a slight bias towards increased low end torque.

Maybe the reason that a standard cover works best is the cold air??? I would bet its not the flow characteristics. Make a plenum with the stacks in it and it would be SWEET Have a look at the V8 supercar stacks and they're about 10cm long.
-EDIT- Cannot remember if they were Supercar stacks or otherwise that I saw at a race meeting recently...

No, in all honesty I think rb30x is correct.. anything to increase velocity speed is defintely a plus. supercharging follows the same basic principle..

so i got the redline ones
might try and rig up a bit of a CAI once its on the road
