Look what came in the mail this morning. My BS 3" pulley for the e force. $39.99 free shipping.
E force pullies at 6000rpm make an amount of boost based on driven/snout diameter. Estimated at 2 psi less for 5200rpm. When used with the stock drive/crank pulley.
- 3.25" = 7.5~9.5psi
- 3.00" = 9~11psi
- 2.75" = 11~13psi
This was so easy to , pull, and press. The results are immediate. It blows my mind. Why did I waste all that time building small block combos. This smokes any normal build, and have no detonation using the MSD BTR. It actually works and retards dialed to 26 total at 5200rpm. 91 octane and 9+ psi, the power is coming on harder than I ever thought a 305 could put out. The performer cam with a LSA of 112 is perfect, and works with the 906 1.94/1.50 60cc vortec heads like a charm. No plans to rev it higher and change cams.The heavy 85 C10 feels like a toy with the Dynamic built 3000 stall and 3.73 gears.
Every 2.5 psi is supposed to be 40-50 hp. So if My performer cam vortec 305 made 250hp NA, and e forced at 5psi made 350hp. Now it is making an estimated 450hp! Never has my 350s or 440s been this streetable at anything close to that power level.
Thanks Edelbrock, I am $2000 happy. This 305 hauls. I can twist the trucks 85 mph speedometer completely around in less than 10 seconds .
Should I try the 2.75" pulley? $40 bucks for another 50 hp. The OE block is good for 450hp or so.
