I Know youve probably answered this question a million times but I searched all over the board and couldn't find it. Will it support a superam with an accel base????

Yes it will, but when I switched to a 58mm on my Superram I picked up 2 mph in the quarter. Some will say it's overkill but the SR has 58mm throttle body openings anyway so why not use one? It worked for me. Besides you probably have other serious motor mods if you're using the SR anyway...I would never put one on a stock engine.
