dandan Posted August 20, 2009 Share Posted August 20, 2009 (edited) OK guys.... Can I simply chop off and grind down all of the casting around the trac butterly areas to tidy up the throttle body? Can the throttle body be welded like any other piece of aluminium or is it some strange oddball material. I would need to get the trac butterfly spindle holes welded up as well as the tapped hole for the brass bung you an see. What's the verdict?

Tricky-Ricky Posted August 21, 2009 Share Posted August 21, 2009 (edited) what are the benefits of doing this and what does the trac do Looks nice and clean when polished, and removing the butterfly is said to release 0.005 BHP;) most people remove the TRAC relay anyway, as its a PITA. Edit, TRAC is a primitive traction control, that usually leaves you semi motionless half way out of a junction when you floor it and it senses wheel spin and closes that butterfly.

dandan Posted August 21, 2009 Author Share Posted August 21, 2009 I've had no butterfly in there for quite some time and seen as I'm fitting a replacement body I figured I might as well tidy it up a bit and get rid of all that crap on the outside. It will hopefully make for a better water injection spray as well as the water won't impinge on the (redundant) spindle. Quote Link to comment Share on other sites More sharing options...
