Our man Paul aka spunone is one awesome dude. the guy is an artist.... and a wicked friend.
check out these babies!! 3" tall, 3.75" Big OD and 44mm ID. paul. you outdid yourself. thanks buddy! (IMG:style_emoticons/default/boldblue.gif) 4 total. will look great siamesed together on my webers. but thats another thread LOL Attached image(s) |

Yep, saw the fixture that Paul used in person today when I picked up the stainless steel fuel lines racerchris set out here.
Looks great, and Paul is another terrific teener owner that I am pleased to know through the non-club. |

OOO...nice...are these available for purchase? I have been itching for another reason to weld some alum recently, and my pair of 44 webers would love these (IMG:style_emoticons/default/welder.gif)
Great job regardless, can't wait to see the finished product. Tony |

Tony motor needs 6" tall filters for these stacks..... which is being less than fun with tall manifolds (IMG:style_emoticons/default/smile.gif) |

Awesome craftsmanship, but I still dont see why there is a benefit of having the ends shaped like that. The 29.4mm restrictors on GT3RSR motors dont have the flip at the end. Does anyone have an answer?

No Prob A_Ron . Matt I've heard it has something to do with smoother Air flow no edge to cause turbulance .I've made both think of air as water will it flow over a smooth smooth rock better than a sharp rock ?? Wax on Wax off (IMG:style_emoticons/default/chairfall.gif) at least thats what me be hearing

those look slick. will they fit side by side on top of the carbs or will you have to notch the edges? too bad no one will see them with the filters on. i guess you could make up clear plastic filter tops.

LOL on the clear tops..... theyd be covered in fuel mist from reversion instantaneously |

AC you prob can just sand One stacks edge and the other will nest in it .Just an Idear (IMG:style_emoticons/default/smash.gif)

spunone,
I need some more goodies from ya... I'd like to dyno this stack design too! |

I'm hitting the road tomorrow for my 3000 mile R&D trip with the Hot VWs project engine installed in my test car.... we'll talk when I get back...

Wax on Wax off (IMG:style_emoticons/default/chairfall.gif) at least thats what me be hearing Well, two quarters of fluid mechanics have taught me otherwise, but working with new race stuff for the last 8 months has taught me to test everything before passing judgement. I'd love to get these in CFD. My guess is that there would be a stagnation point where the curl meets the outside of the stack and the air would turbulate and not help anything. But then again, airflow is pretty funky shit. Can you toss out some numbers so I can CAD them up? I'd like to compare my results to jakes. And what kind of air velocity will these things see? |

Damn, I thought I had COSMOS Flow, but I dont. I'm pretty sure its on campus. I'll give it a try on monday.
I tried it by hand and here are some of my thoughts: The important quantity now is Reynolds number. Reynolds number is a unitless value that tells us how the air flow will react. Its calculated based on velocity, density, and relative size (Re= velocity times diameter (of a cylinder) divided by kinematic viscosity). We'll assume the diameter of the object is 5mm (which is the approximation of the curl put on the velocity stack). The kinematic viscosity of air @ 50'C is 1.79x10^-5. I dont know what the air velocity is, but I do know we're solving for a large reynolds number (to see if the air "seperates" at the peak of the radius and creates a turbulent "wake region" at the base). Re= (V)(.005)/(1.79*10^-5) = 10^5 V would have to be 358 m^2/s, which is a very slow air speed. So I'm comfortable saying there is sufficient Reynolds number to have boundary layer separation at the base of the velocity stack. Sorry if that was hard to follow. |
