how can I make a blow off valve??

make long story short.. SEARCHED

how would you guys suggest I go about making my own Blow off valve? I don't mean pouring resin, but maybe you guys have your own tricks of the trade as usual? :thinkerg:

i do appreciate :thumbsup:

Get a fairly thick piece of round styrene and carefully shape it with knives/files. :confused:

Sounds like the best way to me.

Do you have any pictures of the BOV that you want to replicate? Because I have seen a few different styles before... :smile:

try looking around here.

This is also a turbo build up too.

Good thing I bookmarked it.

Here is how Walter Ma made his.

I still got no clue on how he made the it, but the Integra was always very nice!

those are some lengthy threads you guys pulled up there. those are good ones though! anyways, not really helping me too much. I like your idea to scrape and form one from sprue, that would be what I would do, but like I said I just thought I'd ask around 1st and see what ideas you guys have. anyone else? :dunno:

that is it

wheres the turbo on that?
thats pretty much just an intercooler kit, i dont even see BOV

When you bought it the turbo come !! them that go un the exaust and under the headers!!










If you know nothing about a real car
:loser: :bloated: :rolleyes: think about it

I like it:banghead:

what did you use for the clamps?

This is how I would go about it...

Below is a real neat tool that I highly recommend, its a punch and die set by Historex. It allows you to punch out small discs from styrene sheet, they are used alot by military modelers and sadly they don't come cheap! This set cost me nearly £30 (I think!) - that's nearly $50US:eek: But a worthwhile investment if you are a keen scratchbuilder:smile: In the model car world these can be used for such things as bolt/rivet detail in engines etc, gauge faces, shock absorbers and it just so happens we need to make a BOV:biggrin:

This literally took me 5mins and required zero amount of skill - apart from whacking something:biggrin: All I did was to punch 3 discs of styrene from .010, .020 and .030 thickness sheet, the .010 was punched through a slightly bigger hole. I made no attempt accurately work out the size, just picked what looked ok for the purpose of this demo.

The 3 discs were then sandwiched together:bigthumb:

Interesting method, Chris :bigthumb:

Heres some more reference:

I'd carve it out of a thick styrene tube.
