As in the 2 larger throttles in the t-body, or DAG is only used on the Port Throttles?

Yes, the 2 larger throttle bores in the t-body

OK cool.


Just an illustration of the confusion which can occur when referencing LT5 parts as "secondary or secondaries is often used in reference to the Port Throttles.


I just saw a gentleman who is sell DAG-213 for $15.00. He said the quantity sold for $15.00 would be enough to do a few sets of throttleblades. He states that suppliers sell this product in large quantities, like over $500 per gallon and that it has a shelf-life of 24 months from time of manufacture. He suggest using the $15 tube amount that he sells within 30 days, and keep it in the refrigerator to help lengthen its useful life.


Here's his link, sounds like he's a carb rebuilder

Or 5 gallons for $1550 down to 30ml for $25.95

Over the years I've looked over several TBs and only one had DAG applied to the secondary throttle blades. This leads me to speculate DAG was applied during the factory dyno test if acceptable idle behavior could not be achieved otherwise.

Phil,

Well doubtful there’s any DAG on bored out 63mm TBs like mine. I don’t experience any idle issues.

Dom,
Same with my 63mm TB

I took my throttle body apart a while ago, including removal of the throttle blades. The blade alignment is NOT something u can take for granted when u tighten the bolts. There’s enough play that they move around and can easily be out of alignment with it not taking a mm or less to screw things up. I ended up w a sticking throttle.
I took it to Marc for realignment and he also provided a “helper” spring to make sure things close.

DAG Was applied at the Tbody production facility, it is used to control the "Shipping air rate" of the unit on the test fixture. AKA Leakage
