Question as per the title really, I don't have a G60 throttle body to hand and need to know the diameter of the boost bypass valve, can anyone help?
I'll choose my words carefully Jon simply because I know you know what you're talking about but those dimensions seem huge, in my head I thought the primary was about 28mm and the secondary about 42mm and the bypass was about 28 too.. back to the drawing board for me then
The one I have hasn't got a primary/secondary set-up. Just a single butterfly. It looks std, but I'm no G60 expert. Jon
Hi Jon, thanks, but thats not a G60 throttle body. The G60 throttle body is the same as a mk1 GTI, Mk2 16v etc throttle body with a primary and secondary valve but with the addition of a third valve underneath to dump boost pressure.
Mickey your right. 52 and 35mm ID's resp. There is a single inlet as specified earlier which then splits internally into a primary/secondary butterfly. Will have to use this for something now...... Jon
Feel free to hijack away Jon Does the one you have NOT have the third butterfly underneath? In all respects it sounds like a G60...
All the numbers above are correct, I am 99.9% sure its a G60 TB In summary, primary butterfly ID52mm, sec 35mm combined to a overall single 55mm port and bypass 40mm Jon
