    Thread: Velocity Stack + short ram

    1. 05-27-2008 01:06 PM #1
      Ive searched around for this topic and was unable to find anything but thread related to Cold Air-intake. I cant get a CAI because i live in florida and with hurricanes and flood the chances that ill go over a puddle and end up with a lake inside my engine are great. How about the velocity stack + short ram without heatshield...is a p-flow better? what should i do? thanks!

      The temp from the intake will make little difference if it comes from the fender or behind the battery. Either just drill holes in the bottom or the box or get a bpi flow stack and filter.

      i bought one of these. it mounts in your engine bay but they give you a long tube to route it anywhere. the tube isnt long enought to suck up water.
      personally i love this even though its quite expensive but alot of people on here are selling them.
      read about it. that what sold me

      bpi flow stack and filter? whats that? is it something like a neuspeed p-flow?

      Ive been running the BPi stack for at least a year and a half and love it

      Go on ebay. they have them w/ blox filters for $50 shipped! worst comes to worst you can just get a K&N filter for $40-50.


      I've got a Forge velocity stack + filter on the way for a short ram.

      does it matter if you run the bpi stack and filter without a head shield? i have a ghl cold air intake now..if i switch to bpi will i loose power?

      This is a turbo car, not NA. The heat from the turbo and compression will bring the temps out of the turbo to roughly the same temps and when it leaves the ic it will be the same temp.

      thats a better deal than strait from AEM. think you can fit the 8" one in there?

      This is not entirely true. The outlet temperature of the turbo is a function of 3 things; the compressor efficiency, the pressure ratio and the inlet temperature. What you will find is that a 10* increase in inlet temperature will propagate into an outlet temperature that is more than 10* higher. When you get to higher pressure ratios and less efficient compressors, a small change in inlet temperature can lead to a significant change in outlet temperature.

      edit - and once you get downstream to the intercooler, the hotter inlet temperature will allow more heat to be removed (in terms of Watts), but the outlet temperature of the intercooler will still be higher than it would have with a cooler compressor inlet temperature. As the effectiveness of the intercooler approaches 100%, the outlet temperature will all approach the same temperature (ambient!).

      I live in the worst weather condition you can have.
      Canadian winter...

      All my dubs i owned i run the swiss box mod combine with a KN panel filter all year long.
      When you search here you can see that often it's the best setup you can run and it's cheap 2.

      it's not the best setup. Is it a good setup? yes.

      Is it the best? no.

      A proper velocity stack will yield smother airflow and will pull air in easier than a flat drop-in filter / airbox.

      There is a velocity stack in the stock box

      Shielded with a air duct from the bumper to the heat shiled/box is the best set up with a stack. That is already out however, its called the Vflow

      Just got my forge velocity stack + filter. I was really surprised. The filter is very very good qaulity. As good as a K&N for sure.

      While in school this is correct, in the real world you have to factor in the part about how the compressor sits an inch away from the satanic inferno-like turbine housing. Whether it is 60degF or 80degF going into the compressor, it will more than likely be equally hot as ballz coming out when your turbine housing is glowing red

      Looks good what are the dims on it? 6" inlet with 3" outlet?

      unfortunately the inlet is 2.5", but it is long enough that you can cut it where it goes to 3" and still be safe. That's what i'll do.

      So you'll get a 3" OD tube slip it overtop trace it, cut and weld a 3" stub?

      The temperature rise of the flowing fluid will be ~equal for each inlet condition due to radiant heat from the turbine housing. For the sake of this thread (and because you are I probably the only ones who care), PM me if you want to discuss.

      If i can find some 3" aluminum yes i'll TIG on a little stub to it. If not, i'll cut it and just use a coupler, it shouldnt slip off.

      ^I gave up thinking about thermal-fluid systems when i graduated I think the moral of the story is that you can either have hot air or hatass air coming out of the compressor; however, the difference is negligable, and is proven so on the dyno...where it really counts
