Hi Guys,

I'm on the lookout for some TB trumpets, the need to fit a 40mm O/D Throttle Body.

Oh and I need 4 for them


TIA

Scott

still struggling to get some sensibly priced ones phoenix?

what bike are they from again? Ill keep my eye on ebay for you.

Ooooh! So do I!! If all else fails I might end up fabbing some out of GRP... Turn some floral foam on a pillar drill to the required profile and use it as a buck to make some trumpets....

once i get up and running in the workshop, im going to start making these because it seem like everyone want them

I could do with some longer ones as well for my 55mm jobbies

Are they not available from the OEM? I am using a Triumph engine, and the rubber inlet trumpets are £6 each from Triumph...

Yup still struggling, being a cheapscate, I really don't want to spend £100-200 on then, also there going in an airbox so I don't really need shiney ones, just some plain old plastic ones will do. The TB's are off a Kawasaki GPZ1100.


Cheers

The GPZ1100 airboxes dont come up often unfortunately.

Have you actually asked Suzuki spare parts? They will probably be a cheap spare part if they are still available.

This is what I made when I first went for throttle bodies - they are 40mm internally , but I can only find three `leftover's` the same - they are allso quite long (110mm) as they were for a very short manifold setup .
I dont have any carbon , but I could knock up a set in aluminised glass fibre cloth ? (like the odd one on the right)

Crossflow bits
Or.........if others are likely to want the same , I could turn a former to whatever size needed ?

Thats kind of what I'm planning on doing but with a very shallow trumpet (not much height in the airbox) and a stepped bit so that they slide on to the end of the 40mm tube as it enters the airbox without an internal restriction or ridge....

My plan of attack is

Floral foam
Pillar drill roughly file to shape (IE attack with dremel with sanding drum)
Car body filler
Smooth on pillar drill with files / sand paper
Wax
PVA
4 epoxy GRP trumpets....

I was going to make some moulds out of wax and then melt out the wax afterwards (I even made a little wax lathe to turn them on) but realised it was much easier to make a buck....

Get the saw out then

hint: look at the bike airboxes on ebay. They often have the rubbers attached...

e.g. this CBR600 box has 3 of the 4 still attached...

Imagine this, upside down with the "egg" bit removed



Might look a lot like a stainless steel trumpet......?

Clicky

<---- I used a 48mm bare aluminium spinnings on mine and connected them using jubilee clips and fuel filler pipe .... don't seem to do 40mm, though

Ian Richardson from Wildcat Engineering www.roverv8engine.co.uk supplied mine at a very reasonable price - give him a ring he's a good guy.

The R6 ones are 45 mm long and 42 mm I/D in black rubber, will reduce to 40 mm with ease...and cheap
