My daughter has a 355 stroker in her VT Clubby. It is having idling issues, and was wondering if a 70mm throttle body may help.
It is running a mild cam, and stock heads, HSV extractors, and Auspac twin 2.5" exhaust.
It has heaps of grunt, but just doesnt idle as smooth as it could. Its not the cam. Seems to need more air at idle.
Do you do a throttle body for the VT Holden motor, and how much? Thanks, Ian.

Hi Ian,

To be able to best help out can you please list the complete specs of your daughter's car? Manual/Auto cam specs, custom tuned etc

Thanks in advance,
Steve

Your problem is elsewhere, there is no way a bigger throttle will affect idle. Is the idle air control valve working? A bigger throttle may make a bit more power up top but saying it will fix the idle is like adjusting idle stop screw out on the throttle you have.

 

[MACE]

To be clear for us to suggest that a larger throttle body would solve idling issues would be very premature, if anything the seal on our throttle bodies can be better then from factory so it would likely make the problem worse not better , hence my answer to the question

Sure cracking open or drilling a hole in the butterfly are effectively zero cost solutions, it may also be masking the underlying problem/trait of the setup, which isn't a good idea

What he said ^

so its 190$ for the 70mm throttle body if a standard 5l throttle body is sent in for you to bore out?
or have i read that wrong ('changover' price)
