Centrifugal setup with velocity stack or no filter

[OXFORDS550GT]

Is there any benefit in running a centrifugal setup with a velocity stack or no filter? I can't find the answer anywhere. I've seen it on a ton in race setups.

less restriction is always more power

i wouldn't run open blower on the street, too much dirt, we pull at the track, but not on the street

Do you have to have a tune for it. I saw Lund tune a car without the intake a few days ago ?

So I posted about this. I dynoed the car with the stock PC setup and then removed the entire inlet on the blower. Gained zero. Maybe the velocity stack would add some but I can't see much that is worth the risk. YMMV.

Has anyone done back to back dynos with the stock air box vs. open blower or JLT intake with Paxton/Vortex?
Trying to decide if the after market intake is worth the cost when I order a Paxton.

Cool!
Did you dyno or run it at the track before & after JLT vs. open blower?

Is there any sound difference also, like more spool?

Hasn't been on a Dyno yet. The Supercharger has a little more "whistle" to it at idle. Haven't had a chance to really get on it yet to see current boost levels. I should be around 8-10psi. I also haven't been to the track yet, I plan on going soon.

My last dyno run was after adding the cat delete kit. For shits and giggles, the last run I did was without the intake assembly. I went from 577 to 604 on hp. without the filter setup.

Nice do You daily your car? Do you ever find dirt in your intercooler ?

Mines a DD. And no dirt.... I just started driving with the inlet screen. Going to put the JLT intake back on soon and run the screen at the track. The odds of something getting into the inlet are pretty slim.

Was this because of the cat delete or the open filter?

I would imagine that the cat delete attributed to the higher numbers.

The 577 was cat delete with filter and 604 without.
