Big bubba bov
Anyone running a BIG BUBBA BOV on their A&A KIT? I am finishing up my build and thinking about swapping over to the BIG BUBBA from the Raceport 52mm.
Any benefits in swapping over?

I have a Big Bubba one on my kit that I am getting installed. I heard it's loud as hell, lol. Not sure if there is a ton of benefits to it vs the 52mm Raceport

Yea I heard it is loud, but the few videos I have seen on youtube it sounds pretty damn good. I am a bit confused though because the A&A site shows the Big Bubba as a 52mm. When I bought my TI kit I got the 50mm Raceport. So guess trying to figure out if bigger is better when increasing power. I am planning on pushing the TI head unit to about 800whp+, and probably upgrading to the YSI in the future.

You are right, the Big Bubba is 52mm and the Raceport is 50mm. Not sure if there is a real difference in the two. I also have the TI kit. I am building a 416 stroker and adding the kit to that. Should easily be over 850 whp with the supporting mods. I am shooting for 1000whp with no meth. Going FORE dual or triple pump setup with port injection and flex fuel. I really would like 1000whp on pump 93. Not alot of E85 around east Texas.

If you want the sound go for it. But it wont add any power. Under boost the blow off valve is closed.

Nice man sounds like you are building a beast. I did a drop in kit on my stock 376. Thinking about building a 427 later in the future. I upgrade all the DI stuff XDI 65% and LPE Big Bore, DSX lowside. I thought about doing the Fore Dual as well, but curious how my setup will do with current mods. I will not be doing any meth trying my best to stay away from it. I am in the same boat not alot of access to E85 here on the island of Oahu either. So fingers crossed I can get ole girl to the 800WHP mark. Ryne Cunnigham is tuning her and he said should be doable. I am thinking of adding port later own as well. Trying to hold our to see what DSX comes up with on their kit. Keep me posted on your build man definitely wanna see where you end up.
