Florida_1959

All, I am in the final stages of my AA supercharger install on my 2012 GS manual trans. I have upgraded to the Prospeed dual fans, alky controls meth injection and will be using a BAP. I am running a 10% OD pulley. My question is, with the added dual fans, BAP and Alky system, do you think the stock alternator will be sufficient? if not, what amp alternator can a upgrade too before I will run into problems with the computer? Im trying to do everything all at once so that I dont have to go back into it, as Id rather just be one and done then enjoy the ride. I live in south florida, so you can almost gaurantee the AC will be running all the time too.

Also I have heard that Horse Power sales closed, anyone have a tuner that they can recommend that has proven themselves.

Thanks for all the help from the experts here.

For dyno tuning, I would recommend using Howard Tanner at Redline Motorsports in Pomano Beach

Shop specializes in late model Corvettes and Howard is an excellent tuner ...

I have the Prospeed dual fan set up, and at idle in hot weather, the voltage would drop with the stock alternator due to increased draw from the fans. I got a Mechman 170 amp alternator from Bret (blownbluez06@rktperformance), who is a forum vendor. No more voltage issues and it looks better.

I added one of Brett’s 170 and it does great. Wonderful upgrade

If you're wanting to do it all at once then I would just do it and be done with it. The alternator both suggested above seems to be the one everyone goes with and has great feedback on. I have pretty much the same mods and fan setup and my voltage drops to high 12's to low 13s when it's hot out with the stock alternator
