Annular boosters on a Tunnel Ram
Ok for those interested I started working on these main bodies this am.
First I measured and verified the supplied air bleeds. .033 MAB and .070 IAB then the squirters, they all measured.033.
Next I drilled and tapped for transition slot restrictions. I use a 10-32 tap so I can use the brass for either TSR or Air bleeds.
I did notice that the transition slot passage had a shoulder inside that measured.086 so I’m assuming that if/when it comes time to tune the transition slot I have a starting point at smaller than that.
Then I sprayed everything down good with carb cleaner and blew everything out with air. Wrapped them back up and now it’s time to pull the carbs off FF the car and start the cleaning/swapping process.
Thinking I’ll drop 4 numbers on my main jets and maybe .001 on my IFR’s to start with and go from there.
Thoughts?
