what i have done in the past is tap into my map sensor, at wot through the power band i look for less than .5 in of vacuum.

if you are already at this or better, a v stack wont really help because the air stream is already unrestricted at that engines airflow needs at high load

if you are over .5 in vacuum and want to improve you could experiment with a v stack , BUT the restriction might not actually be the filter but throttle body or ducting


I'm not even sure if ima put it my car

#321221 Well sometime maybe next week I'll be able to make it. The CNC program I had to write for it was a little bit over 4 pages long just for the part and I typed it all in the controller, fixed all the bugs tonight and watched it run the part on the screen and it worked great! But I found out last week I'll have to write another program to bore out some jaws for the machine to fit the 4 1/2" diameter piece of aluminum since none of the jaws are big enough for it. :thumbdown: if I can remember I'll take some pics of everything I've done so far and I get my friend to take a video of the part being made. And as of right now I'm just making it for my class project since its basically my final exam grade in that class.

#322146 Well tomorrow is my last day of this class for the semester so I get to make the part tomorrow so more pics tomorrow night :thumb: would have done it Tuesday but I decided to let the others go since I'm making the biggest part it will take the most time to make everyone else's part was between 1/2"-2" Long and 1" outer diameter max and my part is 3 1/2" long and 4 1/2" outer diameter I figured I'd be more likely to fuck the machine up and take the most time :thumbdown:

#326617 if i had to make a v stack i would use a piece of metal tube and put it on a lathe. then work the v stack shape like making a bowl

also for a daily/track car i always wanted a exhaust cutout on my intake. one side a nice stock intake on the other just a push of a button away a v stack no filter..... dreaming for right now

#329097 what kind of machine you turning that thing on? I work as a cnc programmer. its always exciting to talk to another machinist.

We have a small haas CNC lathe I'm not sure of the model but its small and old and the piece of aluminum I had was to big so we was gonna have to cut jaws to use it and we never got to do it so I was gonna try and use a manual lathe in class but they are small to and I tried to flip the jaws around but I don't like holding on to a part that is 4 inches long by 1/4-1/2 inch and spinning it at high speeds to cut it so I never really got around to it but we do have a big lathe I could make it on but I have no idea how to use it :thumbdown: but I have managed to make a shift knob for my car and my friend has been making pedals for his blazer so I think I'll make pedals for my car now since mine are starting to wear down

Here is my shift knob

#329203 imo seeing as I think you said your cold air intake went down into the bumper.. I would probably make a bumper air duct that fit in the fog light hole.. I think that would be pretty sweet.. but then again its only my opinion

edit.. I guess I should have looked at the dates of these posts lol

#329217 thats awesome man. haas makes a nice machine. i use a haas super mini mill 2 every day as my main machine these days but my last shop was a production company of hydraulic motors and gear boxes. i got to use some sweet machines man. a verticle lathe with live tooling as tall as the warehouse that i had to load with a crane. turning 300lb motor body housings for the most part. also a 5 axis milling machine that was sweet but you had to use mastercam to program it because it gets crazy.

now i just do little aluminum prototyping stuff. nice because my back doesn't hurt as much, but keep it up man CNC is a great way to make money. I'm only 23 and i'm already pulling close to 40k a year.

I wished we had a 5 axis mill in class I could make some crazy stuff then. We just got a 3 axis CNC mill and a few manuals but we upgraded one manual to where it will cut pockets and circles and lines it's pretty sweet and our teacher is trying to get the college to get another CNC mill and a few more machines which would be awesome. I like running the manuals more since you can make something and be like yeah I made that and be proud of it unlike on the CNC where you make the program and put it in and it make the part for you but we don't have master cam yet so we have to manually write the program and since I already took both CNC classes I won't be able to learn master cam

#329261 my old boss just gave me a copy from the machine shop and i learned how to use mastercam that way. i do most of my programming on the spot now, i just type them up in microsoft note pad and use a usb port to transfer the program, but mostly because my new job has bobcam instead of mastercam and it sucks. i feel yea on the manual machining vs. CNC thing but at my new job i use ten thousandth diameter endmills to make micro groves for injection molds for gold micro-connectors with tolerances of .001"+/- and basically without CNC fuck that, but simple shapes i just use our bridgeport old manual mill. thats fucking awesome that you have a retrofitted manual that can do radius's, that would make a world of difference. stick with it man, and when you get to do crazy multi axis machining you'll appreciate CNC more just the ability to make fucking anything no matter how small.

#329292 If we had a 5 axis I'd port my head haha :thumb:

#329342 i bored out my moped and got a little 40cc motor going 60 miles an hour. its 70cc now i think, but you don't get to fuck around with the machines much just because of how high the over head is on machine shops. you know the saying if the spindle aint turning the shop aint earning.
