3 bolt's on the crank pulley? Could end up like this one did.

 

Wow...that's not good

 

ok I will bite.... Hemi what the hell was that carnage from. looks to be a old V-belt setup.

 

88mph?

 

Yup, your correct. It came apart after a 9.8x pass@138 mph. That steel drive pulley only spun an altenator, not a blower. The engine was a 605 cubed Hemi making 805hp/800ft lbs, tq. An F1A series blower is capable of making up to a 1000 hp at the same rpm as the 605. My concern is how much that Procharger aluminum crank pulley can handle only using 3 bolts. We have a few, off the wall Procharger builds going on at this time and none use less than 6 bolts on the drive pulley. Just my .02

 

loox good

 

More specs on the motor, please. I've never seen a F1A TBI.

 

Well its not going to be TBI for long

Motor Specs
383 , Eagle forged crank, eagle H-beam rods, Diamond forged pistons and rings JE pins 4bolt studded mains, AFR 180 Heads with ARP bolts; 8:7:1 Compression, Factory roller block, Crower roller cam 220 / 228 @50 .531" / .553 lift, Com Cams magnum roller rockers screw in studds. Moroso Deep Sump pan.

THis summer I will be changing the TBI out for a Accel Proram system with thier DFI ECM and a transgo trans controller. I have a 5" pully on the F1A to keep the boost down for now.

 

It lives.....
