no one else with input?

 

Why do you ask? This is info I would not even have a clue as to what it was with out running out to the car and measure it with something.

Tell us more!! Working on something big?

 

Comparison sake!

More info contributed the better!!

 

Brad
here are my set up.

13-B big street port using GSL-SE internals pin rotors, etc etc. (both engines in the RX-3 and FB have SE internals), GSL_SE flwheel, 4 puck (RX-3), 6 puck (FB) and 3500 lbs pressure plate.

48 IDA
42 or 43 mm chokes**
Idle holder/jet: 120/75
Main Air/Fuel: F2 & F11, 150-175/220-245**
2 1/8 dual exhaust to a magnafow muffler. Yes, there are 3 ft long glass packs but they only lasted less a week. One of these days, I will take them off completely.


**depending on my mood for that day.

 

what rpm do you shift @ Mel for normal driving?

 

13b half bridge-
48 ida
43mm chokes stock velocity stacks
8500rpm

12a stock port with header-
48 ida
37mm chokes
7k rpm

 

about 3500. due to my large ports and large venturies, my low end suck but good for top end. wish I can find my video tape reving the engine past 9500 at standing still.
