home made twin throttle body

[VN-88]

hey guys, im currently doing this course in a tafe and i have access to many things like welders ect, even tho i have my own, but we gotta do a project and i wana make my own twin throttle bodies, im trying to decide on how to do it and if i should, if any one has pics or plans or anything to help id love it.

any thing u can tell me would help so much, ive got alot of other mods and i think this one will just top my car off

Shouldn't be to hard. Just make a metal box to fit to the current inlet valley. Like cut the top of the valley off as much as you can. Then on the metal box make mounts to take the two throttle bodies.

[CSL]

the best way to do it as i see it, is tig weld, or even spot weld up a box, prob about 300mm long, and 200 wide and 150 deep, now get a hold of an old elbow for the vn(the bit just passed the throttle body) and cut the flange off. now mount that on the box, but off set from centre so the box doesnt foul the firewall. get some 3mm mild steel, and chop up some squares with holes in them, to reinforce the box, cut 2 holes in the box, and mount the throttle body on with screws and gaskets. now their is a little pin where the cruise control hooks up to, measure the distance between those two pins and as accruatly as possible get some flat bar (~3by5byX(x being the distance between the TB's)) and join em up.
now i just made that up then, but in my head it looks alright, however will probally not work, however you should be able to find a pic somewhere, but cheers for getting my brain movin

I'll try and draw you an easyish one to make soon when I'm not so sleepy

I assume this is for the 6? what sort of power gains we looking at here?

i made one a few weeks ago i tryed to post pics but it wouldn't work
all i did was cut the top off made a flange to weld back on and an Alloy box about 300 long 185 high 125 wide at the top and 75mm at the bottom. drilled 2 60mm holes in one side and made adapters to suit tbs

still havent fitted it. Im half way thought making a buggy running v6, gearbox, diff brakes and suspension out of my spare car. so i think i will test on that

not very hard to do the little fiddlely parts r the worst

tapping all holes makes fitting easier

mild steel and alloy???

[VN-88]

they all seem good but will i need acurate measurements for the size ect so the car will still run right, thanks for some diagrams and plans foamy, that would help so much


also i was thinking, what if say were the corner part is between the penium and the tb u made it so it comes of around both sides the penium and next to the fuel rails, so u can have on tb on both sides?? would that improve it at all or even work?

[VN-88]

Does that help ?????

Berlina,

Being such an unltimately lack-luster engine in its N/A form (thinking of V6 Vengance) has your sons walker manifold made much of a difference? I Wonder if the manifold is strong enough to force some air through it.

has he got the plans on how he made it, it would have to make some difference maybe not much but some.

so if there are plans can u please post em here or pm them to me

My son's Vr is also N/a....No turbo Yet!!!!

It made 185.5 rwhp @ Summernats. With leaning out top end...My fault I think, I didnt turn the malpassi back up to where it should have been for the magna injectors.

A proper tune @ Sam's Performance should fix the leaning out prob.

I dont think Anthony (Walker Performance) will give me the plans as this is his business

Cheers
