You for got the alky. How large a radiator you run george? Size of fan? I am planning on upsizing the radiator too. Perhaps the extra capacity will require less fan and pump use.
It all works now. I just think the optimas have very little reserve capacity.

I have a pretty good sized radiator with 2 10" fans. Yes I run Alcohol. The yellow top Optima I have is Group size 31T it has 155 reserved minutes. I like running an alternator for its consistency in volts (very important) 13.5 or so all the way down the track pass after pass after pass.
Seriously there are a bunch of different ways you could go.............this combo has been working for me for years and years. GTO George Last edited by GTOGEORGE; 01-02-2016 at 12:33 PM. |

16v is the way to go. I had an issue with the electric fan popping the fuse. Called the manufacturer and they told me to put a bigger fuse in. I questioned it but it hasn't given me any other problems. Increase your volts you increase resistance.

Mines pushing 15-1 and the 16v does better than 12v. Just saying.

Agreed.........compression makes a differance 16 volts would help the starter. You can still run an alternator for consistency in volts. GTO George |

The 6 volt starter in my old Baja Bug cranked so fast with 12 volts that I think the engine slowed down at idle. LOL Never hurt the starter.

Throughout the 90s when I was mud dragging, I switched over to 16 volts to compensate for the voltage drop that I encountered from not running an alternator. I was running a 399 cubic inch sbc with 13:1 compression in a 1974 Chevy truck with factory wiring still in place. Typically I would make 6 passes at around 4.4 seconds per pass (150 foot track in 12-18" foot deep mud) plus staging and warm-up. By the end of my 4th pass, the throttle response would get sloppy with the 12v battery in place, but with the 16v it remained crisp throughout the day. I was running a MSD 6AL with a 2 step box, trans brake, ACD air shifter, Moroso water pump drive, large electric fan on the radiator, a Holley blue fuel pump and an electric fan on my trans cooler.

FYI
I had been running 12V Optimas in my 72 Olds 442 race car for 8 seasons. Switched to XS 16V last year. Never going back to 12V. Everything is better.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
