Velocity stack position

**Quest** · 13-08-2008 12:20 AM

Has anyone here installed their velocity stack infront of the radiator behind the front bumper? Planning on moving mine from behind the slotted fin and change the ex flex pipe with pvc bends etc. Looking for install or space constraint issues. Thanks in advance.

I just thought that it would scoop more air, being nearer to the front of the car with a larger surface area of the stack being exposed to direct air...where it is at currently, behind the fin, the holes are smaller than the dia of the stack, which means that the true purpose of a larger dia scoop is not being used properly...apart from that, air is not being rammed in or scooped, but blown through the smallish fin slots in the middle of the stack.....which is basically redirected air, as the bumper surely disturbs this.

Am I making sense? These are just my personal novice opinions

...and I am just questioning what I think is being taken for granted.

LOL dodgy ghetto style i pierced a hole in the pipe to cable tie it, then cause it was impossible to stick my phat arms into just next to the radiator i couldn't cable tie it to anything.

*note: i was too lazy to take bumper off*

i'll fix it up when i can be stuffed cause i have a fair bit of aluminium piping left

So fed it from next to the radiator > around the corner to the resonator and up to the hole.

Maybe these illustrative pics will help...even if I use aluminium, don't you think the is more chance of ram air as opposed to the negatives of the radiator heating up the pvc pipe..surely, this can be made heat resistance....also, the problem will only arise when you are slow moving??..If you are on the freeway, the air will be blowing the heat back towards the radiator anyway?
