The next source of frustration - starting 'er up

<< < (3/4) > >>

JrFuel Hayden:
All of the Heritage Jrfuelers use two 12 volt battery in series to start their cars. With just a good Hi-Torque flywheel starter.
We run 15.5 to 16 compression and a 20 amp MSD mag. Now you may get by with a single 12 volt battery with lower compression and your vertex. I have found some great, but not cheap supper light weight batteries, like less than 10 lbs for both batteries. Hayden Wheels sells a remote battery pack, and I could sell just the batteries if you are interested in mounting the batteries in the car. It helps if you should ever kill the motor on the burn-out and no crew member has to haul the battery or cables back to your tow car. We use the remote BatteryPak, because JF is very weight aware. 3.5 lbs per CI with driver. I switched to the Hayden BatteryPak when I found the light batteries because all of our team is over 70. We don't need to charge the battery all week-end, just before we leave for the races, and we have been using the same batterypak for 4 years. I also use a one pound 14 amp battery in the car to power the transbrake and RacePak. 
One other thing that might help you, we spin the motor over with out plugs when we 1'st start the car in the morning, that gets our fuel system bled, and oil pressure up. We look for fuel coming out the plug holes.

  Thanks for the 16v idea. I'll look into that a bit further. One battery instead of two. Sounds good.

retroboy:
Thanks everybody for your ideas. I like the idea of spinin' her over with the plugs out to get the fuel up. I'm going to borrow a guys standard Chrysler magnetic dist and MSD6a on the weekend just to see if it helps.  Failing that I'll try increased battery voltage. I'm in Australia so Jon's set up might be tricky but I know I can get the 16 volt jobbie mentioned. Maybe I can find someone locally who can lend me one to try. I'll post next week after I try the ignition change.

PSweeney:
you don't say what CR you're running but if I were you, stick to 12v, lose the mag and get an MSD pro-billet dizzy. Either the mags bad, starters on it's way out or you have another issued building compression when cranking, ie tight lash, leaky seats, head gasket or rings.

retroboy:
Well I'd like to say yep that's it as simple as that but the Mag has just been serviced and magnets recharged, the starter is a new gear reduction job that has maybe six starts plus a bit of tryin' ! And the engine has 15 mins running time here in my shed. Going to try a conventional ignition and will report back.
