Or at least what I think it is :-)



So after doing the double throttle mod I decided to do the thermowax mod.
It's the little thing on the rear of the TB which has waterline connections on the upper left (near firewall) and lower side. Both coming and returning to the engine block (rear plate)

I have seen several ways to 'solve' this, and this is mine.

First pic: the TB line comming from the rear plate near the UIM. water hose running upwards to where the TB should be (removed in this pic)

Second pic: TB water hose routed towards the entrance on the rear plate (near oil pedestrial)

Third pic: thermowax unit removed from the TB. No block of plates needed as no water is running through it.
throtle valves are able to open fully under any circumstance.

This is how I did it and by no means a 'proven modification'.

Any comments are most welcome.

 

any comments?

 

in the 2nd gen section this is widely being discussed but they close some holes by welding it. IS this also necessary on the 3rd gen TB?
